Logitech Chaos Spectrum wireless Bluetooth USB connector

The new mouse claims to be as good or better than its wired counterparts.

We’re living in a world where the mouse and keyboard are quickly becoming legacy inputs. The future is a quickly-changing concept, now filled with gesture recognition and voice-only interfaces, and it surely doesn’t look the same as it did when the first mouse was brought to market in 1981.

But the basic idea of a mouse hasn’t changed in the last 25 years, and it’s still a staple of desktop computing, especially for gamers. What has changed, though, is the level of technology in these mice. Advances in sensors, microcontrollers, and wireless protocols have kept users satisfied over the years with increasing reliability and responsiveness.

However, when it comes to wireless mice, there has been a disconnect between perception and reality. Wireless mice are seen as laggier, not as accurate, or incapable of holding a charge for long enough.

Logitech, a Swiss company known for their gaming peripherals, wants to destroy those perceptions with one product.

Today Logitech is announcing its G900 Chaos Spectrum gaming mouse, and with it, a list of hefty claims. The wireless mouse is reported to respond faster than wired alternatives, and immune to high levels of radio interference. It also only weighs 107 grams, lighter than its competitors by about 20 grams. However, it also claims to have longer battery life, clocking in at 32 hours of continuous use.

The G900 Chaos Spectrum has been in development for 3 years, a joint venture between Logitech’s Swiss and Irish R&D centers. The mouse is Logitech’s big play to become an even more dominant force in professional gaming, and in that pursuit they set to create the professional’s wireless gaming mouse.

These are bold claims. So, Logitech flew us to Switzerland to test it for ourselves.

Nestled in the hills next to Lake Geneva, Logitech’s Swiss home is located on the École Polytechnique Fédérale de Lausanne campus, about an hour outside of Geneva’s city limits.

Here, the company does most of its latency and wireless testing. Their building houses a full anechoic chamber, which completely isolates anything in the room from any wireless network or connectivity. The compound is also home to a host of custom contraptions meant to poke, prod, accelerate, decelerate, track, and jog computer peripherals within an inch of their life, and then a little bit more.

In the room containing the anechoic chamber, a cart with plastic shelves overflows with gaming mice. And not just Logitech’s. Here, the company tests its mice against its competitors with a standardized test it has devised.

The mouse is placed on a styrofoam platform, in a contraption they call a “jogger.” It’s a clamp around the mouse with a moving paddle underneath, which causes the mouse to endlessly draw circles. The RF receiver is placed about 3 feet away, and a cord connecting the receiver to the computer is snaked through a tiny hole in the chamber’s wall.

The mouse is set to jog, and perfect circles can be seen on the computer outside. Then, an antenna in the chamber then blasts the mouse with wireless traffic on multiple bands and frequencies like Wi-fi, Bluetooth, and 3G. This simulates a noisy RF environment, like would be seen at a LAN party.

As the mouse is being blasted (which is a silent process), I’m standing outside the chamber with two Logitech engineers, who are patiently explaining how the mouse jumps from frequency to frequency in order to mitigate interference. The G900 is running perfect circles.

Inside the anechoic chamber, the Logitech G900 is seated on the jogger, which simulates the mouse moving over a surface. Dave Gershgorn

After a few minutes, we switch mice. Somebody suggests the Razer Mamba, Logitech’s biggest competitor in this space.

Same test, same interference, but suddenly the circles are oblong, and the input jumps erratically.

An engineer explains that when the mice jump to a different frequency, they don’t hand off the input perfectly: that gap in transmission accounts for the jump.

We test mouse after mouse, blasting more than 20 times the levels of RF Logitech recorded at a LAN party before we had arrived. None drew perfect circles except the G900.

Top, the G900 tested against heavy wireless interference. Bottom, a competitor fares against the same level of wireless traffic. Dave Gershgorn

This might spoil the ending, but Logitech consistently outperformed their competition (albeit in tests of their own design). The methods they use are interesting, and the data speaks for itself, but what’s important to remember is that these are improvements that very few people, if any, would be able to perceive. Even with a 144 Hz monitor, the millisecond different between the G900 and a wired mouse, or even between other wireless mice, only means about a frame of video. While that frame might mean virtual life or death for the most professional gamers, it’s not something I could notice.

However, the methods of testing were nifty.

The sensor acceleration and deceleration were recorded by connecting the mouse to a computer, and placing it on a mechanically spinning surface, like a turntable. Knowing the exact acceleration of that turntable, the engineer could match the input of the mouse to that data. The test mouse looks like it’s paying for some horrible crime committed against peripherals everywhere. It’s hot-glued and clamped to a metal bar that holds it in place during the test.

The top two charts show acceleration start time for the G900, pitted against the Razer DeathAdder Chroma (a wired gaming mouse) in on the left, and the wireless Razer Mamba. In both tests, the G900’s acceleration time proved faster. The bottom two charts show the quality of acceleration from G900 on the left, and the Razer Mamba on the right. A more consistent wave is better. The G900 has some aberrations, but is overall more consistent than the Mamba.

Material design represented a huge effort in the production of the Chaos Spectrum as well. The result is a mouse that isn’t built like anything else on the market.

But the heart of Logitech’s pitch is more than just this one model of mouse. The G900 is more a proof of concept than anything else. Wireless can be better. Even inviting me and other journalists into the Swiss lab was a show of bravado meant to justify the numbers.

Posters in the facility hinted that wireless keyboards could be the next on the horizon. And that’s a good thing. We’re living in a time where billions are invested in being able to wave our arms at computers, so they can tell what we’re doing. But somewhere, nestled in the hills of Switzerland, there’s a company that’s trying to perfect what we already have.

The Human Race Will Come To An End. What’s Next?

What does the future have in store for the human race?

In his new book, Chip Walter analyzes how modern humans evolved into today’s dominant, and only surviving human, species. Here he speculates on humanity’s next chapter.

Evolution, as the past 4 billion years have repeatedly illustrated, holds an endless supply of tricks up its long and ancient sleeve. Anything is possible, given enough millennia. Inevitably the forces of natural selection will require us to branch out into differentiated versions of our current selves, like so many Galápagos finches… assuming, that is, that we have enough time to leave our evolution to our genes.

We won’t, though. Instead, we will come to an end, and rather soon. We may be the last apes standing, but we won’t be standing for long.

A startling thought, this, but all of the gears and levers of evolution indicate that when we became the symbolic creature, an animal capable of ardently transforming fired synapses into decisions, choices, art, and invention, we simultaneously caught ourselves in our own crosshairs. Because with these deft and purposeful powers, we also devised a new kind of evolution, the cultural variety, driven by creativity and invention. So began a long string of social, cultural, and technological leaps unencumbered by old biological apparatuses such as proteins and molecules.

In ourselves we may finally have met our match: an evolutionary force to which even we cannot adapt. At first glance you might think that this would be a boon to our kind. How better to better our lot than with fire and wheels, steam engines, automobiles, fast food, satellites, computers, cell phones, and robots, not to mention mathematics, money, art, and literature, each conspicuously designed to reduce work and improve the quality of our lives. But it turns out not to be that simple. Improvements sometimes have unintended consequences. With the execution of every bright new idea it seems we find ourselves instantly in need of still newer solutions that only seem to make the world more complicated. We are ginning up so much change, fashioning thingamabobs, weaponry, pollutants, and complexity in general, so swiftly, that as creatures genetically bred to a planet quite recently bereft of technical and cultural convolutions, we are having an exceedingly difficult time keeping up, even though we are the agents of the very change that is throttling us. The consequence of our incessant innovating is that it has led us inevitably, paradoxically, irrevocably, to invent a world for which we are altogether ill fit. In ourselves we may finally have met our match: an evolutionary force to which even we cannot adapt.

We are undoing ourselves because the old baggage of our evolution impels us to. We already know that every animal wants power over its environment and does its level best to gain it. Our DNA demands survival. It is just that the neoteny (youthfulness) that has made us the Swiss Army knife of creatures, and the last ape standing, has only amplified, not replaced, the primal drives of the animals we once were. Fear, rage, and appetites that cry for instant gratification are still very much with us. That combination of our powers of invention and our ancient needs will, I suspect, soon carry us off from the grand emporium of living things.

Stress, as the experience of lab rats everywhere has repeatedly testified, is a sign that a living thing is growing increasingly unfit for the world in which it lives, and as Darwin and Alfred Russel Wallace astutely observed more than 150 years ago, when a living thing and its environment are no longer a good match, something has to give, and it is always the living thing.

How are we handling our stress? Not too well. Rather than relaxing or getting more exercise when pressures mount, studies show that we instead skip meals, spend more time online or in front of the TV, then overeat and lie awake at night perfectly prepared to enter the next day bleary-eyed, short-tempered, and exhausted. What triggers this behavior? Those old primal drives and appetites we struggle so mightily to ignore.

Which returns us to the question, what next?

Our demise doesn’t have to be a Terminator-style annihilation that leaves the world emptied of all humans, postapocalyptic cities stark and decaying with the smashed remains of our cultural accomplishments. It may be more of a butterfly-like metamorphosis, a transformation in which we step over the Rubicon of our old selves and emerge as a new creature built on our own backs without ever realizing, at least early on, that we are no longer the species we thought we were. Did the first Neanderthal know that he, or she, was no longer Homo heidelbergensis? Those passages are made gradually.

Perhaps we will simply morph into Cyber sapiens,* a new human, infinitely more intelligent than you or I are, perhaps more socially adept, or at least able to juggle large tribes of friends, acquaintances, and business associates with the skill of a circus performer. A creature more capable of keeping up with the change it generates. To handle the challenges of time shortages and long distances, Cyber sapiens may even be able to bilocate or split off multiple, digital versions of themselves, each of whom can blithely live separate lives and then periodically rejoin their various digital selves so that they become a supersize version of a single person. Imagine being able, unlike Robert Frost’s traveler in his poem “The Road Not Taken,” to choose both paths, each with a separate version of yourself. It makes you wonder if something essential in us might disappear should such possibilities come to pass. But then, perhaps, that is what will make the new species new.

A whole group of Homo sapiens are already contemplating what the next version of us might be like. They call themselves transhumanists, anticipating a time when future anthropologists will have looked back on us as a species that had a nice run, but didn’t make it all the way to the future present.

Transhumanists foresee a time when beings will emerge who will literally be part biology and part machine. In this I suspect they are right, the logical next step in a long trend. We are already part and parcel of our technologies after all. When was the last time you checked your cell phone or simply walked to work, hunter-gatherer style? We have long been coevolving with our tools. It’s just that now the lines between humans and machines, reality and virtuality, biology and technology, seem to have become especially blurry and will soon twitch and blink away.

The question now is, can we survive ourselves?Transhumanists predict that by melding molecule-size nanomachines with old-fashioned, carbon-made DNA the next humans might not only speed up their minds and multiply their “selves,” but boost their speed, strength, and creativity, conceiving and inventing hyper-intelligently while they range the world, the solar system, and, in time, the galaxy. In the not-distant future we may trade in the blood that biological evolution has so cunningly crafted over hundreds of millions of years for artificial hemoglobin. We may exchange our current brand of neurons for nanomanufactured digital varieties, find ways to remake our bodies so that we are forever fresh and beautiful, and do away with disease so that death itself finally takes a holiday. The terms male and female may even become passé. To put it simply, a lack of biological constraint may become the defining trait of the next human.

There could be a downside to these sorts of alterations, I suppose, should we find ourselves with what amounts to superhuman powers, but still burdened by our primal luggage. Our newfound capabilities might become more than we can handle. Will we evolve into some version of comic-book heroes and villains, clashing mythically and with terrible consequences? Powers like these give the term cutting edge a new and lethal meaning. And what of those who don’t have access to all of the fresh, amplifying technologies? Should we guard against a world of super-haves and super-have-nots? It is these sides of the equation I wonder about most.

Given evolution’s trajectory, short of another asteroid collision or global cataclysm, we will almost certainly become augmented versions of our current selves. That has been the trend for seven million years. Apes increasingly endowed with more intelligence, and more tools, becoming simultaneously wiser and more lethal. The question now is, can we survive… ourselves? Can we even manage to become the next human? It’s a close question.

I’m counting on the child in us to bail us out, the part that loves to meander and play, go down blind alleys, fancy the impossible, and wonder why. It is the impractical, flexible part we can’t afford to lose in the transition because it makes us free in ways that no other animal can be–fallible and supple and inventive. It’s the part that has gotten us this far. Maybe it will work for the next human, too.

Excel’s Iferror Puts An End To Messy Workarounds

Before the introduction of the IFERROR function in Excel 2007, if you wanted to hide errors displayed by some formulas you had to employ a combination of IF and the ISNA functions, which resulted in Excel having to do the calculation twice. Once to establish whether the result was an error, and again if the result wasn’t an error.

It can be used as a ‘wrapper’ to hide many different errors; #DIV/0!, #NAME?, #NULL!, #NUM!, #REF!, #VALUE!, and one of the most common being VLOOKUP’s #N/A error.

In this tutorial we’re going to look at using it to solve VLOOKUP’s #N/A error.

We’ll cover why we might want Excel to hide this error, and how we can tell Excel to display something more elegant in its place.

Let’s recap VLOOKUP formulas:

Exact Match VLOOKUP:


find this value


in that table


return the value in column x of the table


but only return a result if you can match the




Sorted List VLOOKUP:


find this value


in that table


return the value in column x of the table


Excel will return a #N/A error if it can’t find the value it’s looking for in the table.

Problems with #N/A

2)      #N/A’s present in any cell of a row or column will prevent you adding it up. The result of a SUM on a row or column with #N/A’s will be #N/A.  That’s a show stopper right there.

3)      #N/A’s are not very informative. Something like ‘Not Found’ or ‘Missing’, or ‘0’ would be more helpful.

4)      Just like you can’t add up a column containing cells with #N/A’s, you can’t apply any other formulas to them either. It would be more helpful for Excel to enter a 0 (zero) which won’t break any dependant formulas (well, unless of course you’re dividing by 0).

IFERROR Gets Rid of #N/A

By wrapping your VLOOKUP in an IFERROR function you can tell Excel to hide the error, or put something else (text, a number, or nothing) in its place.

Taking our VLOOKUP example above, and wrapping it in IFERROR, in English our new formula would read:




find this value


in that table


return the value in column x of the table


but only return a result if you can match the




if you can’t find it put the word 'Missing' in the cell


When we enter our formula in Excel, and apply it to the example we used for our VLOOKUP Exact Match example it would look like this:














If we wanted Excel to put a number, say 0 in the cell instead of a word our formula would look like this.














You’ll notice the 0 doesn’t have double quotes ” ” surrounding it like the text ‘Missing’ did. The rule is if you want Excel to enter text you need to surround it in double quotes, but for numbers you just enter them without the double quotes.

To enter nothing, it would read:












To enter a dash – it would read:









) Other Uses

As I mentioned above, it can also hide #DIV/0!, #NAME?, #NULL!, #NUM!, #REF!, and #VALUE!

The other most common error is #DIV/0! 

Say we had a calculation that was =10/0 the result would be #DIV/0!. To hide this we can wrap our formula in the IFERROR like this:


and instead of Excel displaying #DIV/0! it would display ‘Error’

Or if we wanted it to display 0 we’d enter it like this:

=IFERROR(10/0,0) One last thing – Cell Error Print Options

There’s a simple print setting that will allow you to define how errors are displayed when printing.  You can choose to either enter a — in the place of any errors, or leave the cell blank.

In the Page Setup on the Sheet tab choose how you want cell errors displayed from the drop down list.

To Double Capacity By End Of Month, the U.S. Department of Health and Human Services’ troubled insurance-shopping website, will double its user capacity by the end of the month in an effort to eliminate sluggish response times when thousands of people are on the site at the same time, officials said.

The site should be able to handle 50,000 concurrent users by the end of November, and the tech team working on the site expects about 800,000 visits a day by then, said Jeffrey Zients, a former acting director at the White House Office of Management and Budget overseeing fixes to the site.

The site now can handle about 25,000 users at a time before it slows down, although it was unstable at lower volumes in past weeks, he said Friday during a press briefing on the website’s progress.

The site was originally intended to handle about 50,000 concurrent users, but fell short in the first weeks of operation, Zients said. “It’s important to keep in mind here that this is not a simple website,” he added. “It’s a complex system doing complicated work. This is much more than a website for browsing or conducting routine transactions.”

“We realize that many consumers who are seeking coverage in January may have experienced frustration with the site.”

The site must process “millions upon millions of unique circumstances” that users have, including different insurance needs, plan options and eligibility for insurance subsidies, he said.

In addition to the added capacity, the site will include a user-friendly waiting queue when there are spikes in user volumes, and it will give users an option of getting an email notification of a better time to come back, Zients said. Those features will be available by the end of the month, he said.

HHS announced Friday that it is extending the deadline for U.S. residents to sign up for insurance if they want coverage by Jan. 1, due to the widespread site problems after it launched Oct. 1. The new application deadline for Jan. 1 coverage is Dec. 23, eight days later than the original deadline, said Julie Bataille, communications director for the HHS Centers for Medicare and Medicaid Services.

“We realize that many consumers who are seeking coverage in January may have experienced frustration with the site,” Bataille said. “We understand that technical challenges have made comparing plans more difficult in the first months, and we want to give consumers as much time as possible.”

The site still crashed twice during the past week, for about three hours on Wednesday and about 10 minutes on Tuesday. experienced major crashes and sluggish performance in the weeks after its launch, but Zients said Friday the tech team is on track to meet the HHS goal of having it work well for most users by the end of the month. “The system will not work perfectly, but it will operate smoothly for the vast majority of users,” he said. “While there will not be a magic moment at the end of the month when our work will be complete, users coming to the site today are already having a greatly improved experience.”

The site’s error rate when users land on a page was .75 percent this week, down from about 1 percent a week ago and 6 percent just after the site’s launch, he said. Page response times were under one second this week, similar to the response in recent weeks, but much lower than eight seconds in the first weeks after launch.

However, the site still crashed twice during the past week, for about three hours on Wednesday and about 10 minutes on Tuesday, not including scheduled overnight outages used for upgrades.

The tech team working on the site has made more than 300 bug fixes and improvements since mid-October, Zients said. The team has 50 priority fixes to work on next week, he said.

Apple Announces Finance Chief Peter Oppenheimer To Retire At The End Of September

Apple has just announced via a media release that its longtime finance chief Peter Oppenheimer will be retiring at the end of September, ending a roughly 18-year career at the technology giant. The company called it a planned transition so he could take time for himself and his family.

In naming his successor, Apple said Luca Maestri, 50, will gradually take over as CFO in June to allow for a smooth transition. As per the release, during Oppenheimer’s CFO time, Apple’s revenue “grew from $8 to $171 billion”.

It’s interesting that Maestri left Nokia in February 2011, the same month the struggling Finnish cellphone giant announced they were adopting Microsoft’s Windows Phone. He joined Apple in March of last year..

Tim Cook revealed they instantly knew Luca would become Peter’s successor after meeting him during the company’s search for a corporate controller. “His contributions to Apple have already been significant in his time with us and he has quickly gained respect from his colleagues throughout the company,” said Cook.

As for Oppenheimer, 51, Cook praised his many contributions to Apple during his 18-year tenure with the company:

Peter has served as our CFO for the past decade as Apple’s annual revenue grew from $8 billion to $171 billion and our global footprint expanded dramatically. His guidance, leadership and expertise have been instrumental to Apple’s success, not only as our CFO but also in many areas beyond finance, as he frequently took on additional activities to assist across the company. His contributions and integrity as our CFO create a new benchmark for public company CFOs.

Peter is also a dear friend I always knew I could count on. Although I am sad to see him leave, I am happy he is taking time for himself and his family. As all of us who know him would have expected, he has created a professional succession plan to ensure Apple doesn’t miss a beat.

As for Oppenheimer himself, he loves Apple but “for quite some time” has wanted to “live on the central coast of California” and spend more time with his family and sons.

In a bit of personal revelation, the executive said he wanted to get more involved at Cal Poly, his alma mater, travel to interesting parts of the world and finish the requirements for his pilot’s license – “something I have wanted to do for years.” 

As Apple’s annual revenue has grown more than twentyfold during his time as CFO, Peter has overseen development of a disciplined global financial strategy, robust systems and procedures, and a very strong balance sheet. Under his leadership, Apple has built a world-class finance team. Peter has managed facilities expansion including the addition of four data centers and Apple’s new campus in Cupertino, all of which will be powered by renewable energy.

As Apple’s CFO, Oppenheimer manages the controller, treasury, investor relations, tax, information systems, internal audit, facilities, corporate development and human resources functions, reporting directly to CEO Tim Cook.

He also serves on Apple’s executive committee.

According to his Apple bio page, the executive received his Bachelor’s degree from California Polytechnic State University, San Luis Obispo in Agricultural Business and an M.B.A. from Santa Clara University, both with honors.

He is also a member of the Alpha Gamma Rho fraternity.

Oppenheimer joined Apple in 1996 as controller for the Americas. A year later, he became vice president and Worldwide Sales controller and then a corporate controller. Oppenheimer became chief financial officer in 2004, after Fred D. Anderson retired.

Prior to joining Apple, he was Chief Financial Officer of the Claims Services Division for Automatic Data Processing. And before that gig, Oppenheimer had spent six years in the Information Technology Consulting Practice with Coopers and Lybrand, where he managed financial and systems engagements for clients in the insurance, telecommunications, transportation and banking industries.

Prior to joining Apple, Luca was CFO at both Nokia Siemens Networks and Xerox.

Since joining Apple in March 2013, Luca has managed most of Apple’s financial functions and “done an excellent job leading them”, while also working closely with Apple’s senior leadership.

According to Apple:

Luca began his career with General Motors and spent 20 years in finance and operating roles in the Americas, Asia Pacific and Europe. While at GM, Luca had many significant assignments building and operating the business. He was part of the team that established GM’s regional operations in Asia Pacific, including manufacturing investments in China and Thailand. He was later CFO of the team that restructured operations in Brazil and Argentina and returned the region to profitability. His last role at GM was CFO for all of GM’s operations in Europe, which spanned over 45 countries with annual net revenue of approximately $40 billion.

Luca has an exceptionally broad international background, with time spent living and working in Italy, Poland, Ireland, Switzerland, Singapore, Thailand, Brazil and Germany, as well as the U.S.

Luca graduated from Luiss University in Rome with a bachelor’s degree in Economics and received a master’s degree in Science of Management from Boston University.

Yesterday, the investment banking firm Goldman Sachs announced that Oppenheimer has joined its board as an independent director. His 25 years of broad experience across important industries “will add a valuable perspective” to the board, the investment banking firm said.

How To Setup A Logitech Mouse (Beginner’s Guide)

You’ve just bought a new Logitech mouse, but you have no idea how to use it? Well, you don’t need to scratch your head as we bring you the beginner’s guide on how to set up a Logitech mouse.

Interestingly, Logitech has introduced various types of mice since 1982. Whether you’re looking for a normal mouse for your work or you need a multi-functioning gaming mouse, Logitech provides a variety of models.

Well, each type of mouse has a different way of setup. So, let’s jump into how you can use a wired, wireless, and Bluetooth-supporting Logitech mouse. 

How to Setup a Wired Logitech Mouse

While using a wireless mouse, you may face issues with the batteries or their connection. The same thing applies to a Bluetooth-supporting mouse. However, when you use a wired one, all you have to do is connect the two ends, and your mouse works completely fine unless there are faults in the cables.

Thus, when we buy a wireless Logitech mouse, we often receive a cable along with it. This is to ensure that if there’s a fault in our wireless connection, we can use the device with the help of the wire.

Well, setting up a wired Logitech mouse is not a difficult task for anyone. Here’s a general idea of how to do it the correct way so that you do not face any issues with the connection:

How Can I Setup a Wireless Logitech Mouse?

A wireless mouse runs with the help of radio frequency. Hence, you can even control it from a long distance compared to a wired mouse. However, the obstacles in between may not help you use the mouse from a much larger distance.

If you possess a wireless Logitech mouse, you do not require a dedicated cable to use the device. Nonetheless, you need to check whether your mouse has a USB dongle or not. 

Well, most Logitech models provide this inside the box containing your mouse. If you have lost it, you can use the Logitech Unifying receiver that helps connect multiple Logitech input devices.

Before proceeding with the steps below, ensure the wireless Logitech mouse supports your operating system. Now, let’s dive into the detailed guide on setting it up.

Configure Your Mouse Battery

A wireless mouse won’t function if your battery is drained. So, it’s important to insert batteries that are working.

Well, the cells on your Logitech mouse support mostly AA and AAA batteries. For any confusion, we have a comprehensive guide on how to change batteries of a wireless mouse.

In some Logitech mouse models, you have an option to charge your mouse battery. When the device is charging, you see a green light glowing on its dedicated LED.

Plug in Your Wireless USB Dongle

Once you’ve configured your mouse batteries, now you need the dedicated USB dongle. Remember that you can’t use another device’s USB receiver. 

Well, all you have to do is take the USB dongle and insert it into an available port on your PC. Make sure you have plugged it well so there won’t be a connection issue.

Turn on the Mouse

The next step is to turn on your Logitech mouse. The button you’re looking for should be in the bottom section of the device.

By default, the mouse is turned off. To turn it on, simply drag the slider toward the On letter printed on the device. Depending on your Logitech mouse, you’ll have to slide it upwards/downwards, while in some models, you’ll have to drag it sideways. In some models, you can simply press the ON button to turn on the mouse.

Check for the glowing light to ensure your Logitech mouse has turned on. For some reason, your light may not work. In such a case, simply unplug the USB dongle and plug it back again. Then, turn on the mouse, which should now light the LED.

Note: We recommend turning off the mouse once you’ve finished using it. This way, your battery is saved.

Check Connection

In some Logitech mice, you may have to press the Connector button in your mouse. However, most modern mice have removed this option. This means that once you plug in the USB and turn on your mouse, the connection will establish automatically.

But, if your model requires a connection to be set up, simply find the connector button on your mouse. Then, use a pin to press it.

Finally, check if your wireless Logitech mouse is working or not. To do so, drag your mouse around; if the pointer is moving well, Bravo! You’ve done it.

Install a Logitech Software [Optional]

Well, you can download and install either Logi Options+ or Logitech G Hub. These programs help you change the mouse DPI or even increase the polling rate.

How Do You Set up a Bluetooth Logitech Mouse?

Unlike wireless mice, a Bluetooth mouse works only for a shorter distance. Even they use radio waves for communication but in a lower GHz. 

Setting up a Bluetooth Logitech mouse is quite similar to a wireless mouse setup. However, there are a few more added steps you need to do to ensure proper connection.

Before moving on, make sure your Logitech mouse supports your OS. Also, ensure your battery is fine. Then, turn on your mouse and press the Connector button, if available. Now, head to the below guide to set up your input device.

Turn on Bluetooth

Firstly, you must turn on Bluetooth on your mouse and your PC. To turn on the Bluetooth of your mouse, navigate to the bottom and hold the Bluetooth button for a few seconds. This will make the light on your device blink continuously, meaning your mouse is in pairing mode.

Along with the mouse, you need to turn on the Bluetooth of your PC. Here, we will explore the steps on both Windows and macOS.

On Windows 11

On MacOS

Pair Mouse With PC
