If it does not glow, it is not working. You can try another usb port to make sure it is not the usb port that is broken. Other than opening the mouse and finding the loose connection, it will need to be a new mouse.

Mouse not working? Computer virus?
1st suspect is the mouse. try it on another computer or try a different one on urs. It seems like too isolated a problem to be a virus. could be a driver issue.

Wired USB mouse left button stops working
Try reinstalling the drivers. Also, check to see if the mouse works on other computers. See if another mouse works on your computer. These are things that you can try to help figure out where the problem is (driver, mouse, computer). Comment back to tell me the outcome.

What is the best gaming mouse?
It just depends on which games you are playing.For example someone playing a MOBA or MMO would probably need a mouse with more macro buttons on the side.E.g. The Razer NagaWhereas someone playing an FPS game may prefer a mouse with fewer macro buttons. E. g. The Razer DeathadderPersonally I think that you can never have too many buttons but it's a subjective choice depending on multiple factors.Also, some gamers I know prefer to use wireless mice (and keyboards) so they have full freedom of movement.Finally, if you are going to be using the mouse for long periods of time I would also suggest finding one which fits your hand size and does not cause and cramp on your wrist or fingers.

computer mouse broken? need help fixing it...?
Mouse balls get dirty and should be cleaned often. Use clean tap water. If really dirty, you can use a mild soap. I know people who used to clean the ball in their mouth rather than get up and run it under water, but I do not recommend that method. You also should clean inside the mouse where the ball rolls around. Dust and grime collect there too. However, a mouse is very cheap to buy, so why not just get a new one. I recommend a mouse without the rolling ball. It uses a light sensor instead. And they may cost a couple bucks more but are worth it. I also like USB connectors, but the oldeer PS/2 works okay and should be really cheap.

how do i fix my frozen mouse?
I also have a Logitech wireless mouse, and besides being a great mouse, it does kick out sometimes. I find moving the receiver closer to the mouse and pressing the reset button works most times. You might also have other devices interfering with the signal. Also try plugging the receiver into another usb slot. I am not totally sure about the mouse not showing up on screen. You should try rebooting. Also try a corded mouse just to make sure its the mouse and not the computer.

What is the focal distance of an optical mouse?
The focal distance of the laser lens and the distance from the target (i.e. table) that an optical mouse will work with are two different things. You ask for the former, but it seems that you want the later. To answer the question that you asked: Every mouse is different, but you can expect on the range of millimeters. If you can remove the lens from the mouse, then hold it with pliers and move it closer and further from a white sheet of paper under the sun. The height at which the sunlight makes a point on the paper is the focal distance. On a cheap mouse laser lens that I tried, I got about half a centimeter judging by eye.To answer the question that you meant to ask: Every mouse is different, but you can expect on the range of millimeters to just a few centimeters. My nice modern Microsoft Curve wireless mouse fails to work at more than 2-3 millimeters above the mousepad. My Logitech G500 works a good centimeter above the mousepad, and I remember when optical mice first came out how I could hold the mouse a good 5 cm above the desk and still have it detect the motion.I recommend trying to get the oldest optical mouse that you can, the sort with the bright red laser. By my own testing, these seem to work furthest from the targeting surface.

PLEASE TELL ABOUT COMPUTER KEYBOARD IN SIMPLE LANGUAGE?


Hi there, It is a computer peripheral to allow the users to interact with the computers. There are different types of keyboards, some wired and other wireless. Some come with multimedia functions to access your multimedia software. They come in white mostly but black are available. Each language has its own keys settings .i.e for English speaking countries , they use QWERTY keyboards whereas the French use AZERTY keyboards. The keyboards have not changed much throughout the years compared to computer mouse or monitors. A computer cannot be used without a keyboard. I hope this is enough for you to get going! Cheers.

How Do I Clean My Computer Keyboard?
On my standard desktop keyboards I've popped off the keys and cleaned them up. It's a slow and tedious job but it works. First turn off the computer, you do not need to have it on. I usually start by turning the keyboard upside down and tapping it (this hopefully will get any large debris out. Then use the vaccuum/brush to dust off light items. If you've got more stuff in the keyboards you will need to do a little more work. You can carefully lift the keys out (do not jam any sharp object underneath the key). Just try to lift the key from the corner. I usually do a few keys at a time - do not do the whole keyboard at once unless you like puzzles or know all the placements before hand. clean off sticky or caked on stuff from the keys using a damp cloth - I spray windex on paper towels. Make sure keys are dry before replacing them on the board. Everything should be fine when all is done My mother often eats/drinks while on the computer and her keys get sticky and gross ... there's times when things have gotten under the keys and we could not dislodge whatever it was, keys would get stuck or not be able to push down. I was told that it's not really a risky task by our companies computer programmer over 20 years ago. And fortunately with desktop keyboards they are relatively cheap and easy to replace if you should damage them (they sell replacements because accidents happen like spilling a drink on them). Over the years I've cleaned quite a few keyboards without a problem. Just use common sense and be careful, you will do fine. Hope this helps.

How do I fix my computer? The keyboard and the mouse don't register, even during the BIOS bootup. I tried USB and PS/2, but nothing works. I have Windows 7 Pro.
Borrow someone elses keyboard and mouse. if they dont work, probably your ports are fried. You could double verify this by seeing if your keyboard and mouse work on a different computer. I take it you cant see if the BIOS is messed up because you and cant press keys. But your BIOS does not state keyboard error? or beep a lot?ah i see some one else thinks the whole board is failing. its probably a specific chip. If you can solder, this can be fixed if its a worthy board. If not a great/expensive board, all your components are still good and you can get a much better board with some research, maybe with a higher bus speed and latest ports! once you figure out which board you probably ebay it cheap.

I like my computer keyboard but the letters have nearly worn off
My keyboard is going the way of yours, but not yet so much.Perhaps you could try engraving the lettering somehow, to prevent it wearing off immediately. Then run some paint into the engraving.I do not have the tools to do that, so I might try to scratch the letter into the key top, and run paint into that. Another thing I might to, is to drill one or more small holes near the corners of the worn key tops - one for the A, two for the S, and so on, and run paint into the holes with a toothpick or similar. I am sure I would soon learn that the one-hole key is the A. It's more information than a blank key top.

After trying the G Huang Pro during 618, Cherry has been a passerby since then.


During the period of 618, I successively bought wolf brand CIY68 (G yellow pro) / RK87 (gold powder shaft) / Pill Ling FL980 (BOX red). After using it for half a month, I still feel happy, and I have been watching it on Tieba and Aunt Zhang. From the comments and replies of the bosses, it is found that the bosses say that keycaps are also very important. Because both CIY68 and RK87 are ABS keycaps with OEM height, I bought 2 copies of blind boxes at Baldhead’s house for 100 yuan. They said they were blind boxes. In fact, you can choose by yourself. If you don’t leave a message, it will be random by default. After reading the comments, I chose the original villain Mario and Bai Shimmer.


After I got it, I installed a set of white shimmer on the RK87, and it turned out that the opaque keycaps were really hurt. Then there was a set of villain Mario left, and I was not willing to use it for CIY68, so my hands were itchy, and I started looking for switches and keyboards again. For switches, I want to try Jiadalong’s G white pro and G silver pro, and then see During the keycap process, Hua Danniang was brainwashed. So I got 3 more keyboards, and finally I can use the mechanical keyboard for a week without repeating the same. Borrowing from the old man’s reply in the previous article, the key ring leeks are very serious. There are several sets of keycaps every month, and then new switches are released. More and more parts, more and more keyboards.


Hey, it's time to stop, I'm afraid of being known by the family leader, the keyboard is hidden.


RK98+ pick-up white axis


The first one is the RK98 mechanical keyboard (single-mode cable model, the factory tea switch has been removed) bought in JD.com, plus the 105 light-picking white switches bought by JD. Jiadalong's G white pro has planted grass. In addition to the bald boy villain Mario, I often use this keyboard when typing. The only problem is that the keycaps are not transparent, and the lights around the keys glow at night, and the middle is dark, which is very sad.




Compared with the RK87 gold powder switch with white shimmer in the middle, this pick-up white switch is not as crisp as the gold powder switch, and has a soft and waxy feeling. To be honest, typing with these two switches is very comfortable, and the typing sound of the gold powder switch is a little crisper, a bit like a mahjong sound. PS: I bought a double-segment spring for the pick-up white axis.



Lenovo rescuer K7 mechanical keyboard (G silver pro)


I used Jiadalong G yellow pro/G white pro, how can I miss his G silver pro? Before I bought the G silver pro keyboard, I thought about it seriously. My G white switch, RK98, cost 200 yuan, the switch The body cost 150 yuan, and the keycaps cost 50 yuan. Such a set is already 400 yuan. It is better to buy the finished Gauss HS98T. The price/performance ratio of your own set may not be high. Seeing that the price of the G silver pro switch is not cheap, I thought about buying a finished product.


So there is the rescuer K7. I have to say that this keyboard is really heavy, but it feels that the keyboard layout is a bit compact. G silver pro ultra-short keystroke trigger, playing games is really YYDS, this mechanical keyboard also supports full-key hot-swappable, three-mode connection, and built-in battery.




After using it for half a month, this G silver pro has a feeling of pointing and typing, but I still choose my pick-up white switch and gold powder switch for typing. After all, the feeling of using the G silver pro after typing for a long time is still not there. The white shaft and pink shaft are comfortable. If you still want to use it for entertainment after typing, then buying a G silver pro is enough.


Amilor Flower Girl Cherry Blossom Powder Shaft


When I was shopping for keycaps, I occasionally saw the keycap of Hua Danniang. At first glance, I felt pretty good. There are Chinese characters on each keycap, which is full of national trend. The second master in the fan drama, so I bought this Huadanniang keyboard, which I feel is still quite painful. I bought the cherry blossom powder switch. The customer service introduction is similar to the gold powder switch.


Unboxing Keyboard Artist



Take a group photo with three keyboards;



After buying so many keyboards, I found that the key ring is really deep. The Cherry MX1.0 I bought at 199 has been used for almost 2 years. I never thought that I could toss so much on the keyboard. Let me tell you a sad story. My boss found Huadanniang’s keyboard at home. He asked me how many meters it was. I said, look, there are Chinese characters printed on the keycaps. It’s not very expensive. The boss said it’s not very expensive. use. It has only been used for less than a week, and I also took my G502 mouse by the way.



Cost-effective choice: Jiadalong G yellow pro


Long-term text workers taking into account the cost performance: Jiadalong G white pro



Higher typing requirements: TTC gold powder shaft


I haven't touched the mechanical keyboard much: BOX red switch


Playing games: Jiadalong G silver pro


Not recommended: Hua Danniang


If you only like the crackling of green switches and green switches and think this is the feeling of a mechanical keyboard, please ignore my summary;


Last but not least, pragmatic brothers and sisters, it is enough to buy 2-3 keyboards. Keyboards are not a collection of electronic products, and electronic components may malfunction after a long time. Don’t fall into the pit too deep.

When it comes to choosing a keyboard, which brand do I recommend? I will choose to recommend: Lofree Luo Fei! One of the reasons why the Luofei keyboard will be recognized and recommended by me is its outstanding appearance. The keyboard is very important for a person like me who has been sitting in front of the computer for a long time and makes a living by typing. In today's society, it is very important to have a keyboard. It is not difficult, but if we have a keyboard with outstanding appearance and rich functions, then we have to make a good choice.


No, in order to meet my own preferences (keycaps and switches), I created my own exclusive mechanical keyboard. Taking advantage of the 618 promotion, I bought the combination of Xiaoqiao 100-key tofu-colored red switch + summer invasion keycap. Let's experience it together!




Lofree 100-key customized version consists of keyboard and keycap, both of which are packaged in simple primary-color paper. The front of the keyboard switch body has the image logo and brand logo of the product, and the product parameters and manufacturer information are marked on the back. The inner layer of the keycap is fixed with transparent pc, so that the product can be seen intuitively.




As a customizable keyboard, choosing your favorite keycaps becomes the greatest pleasure. This set of "Summer Invasion Plan" uses the "blue" of the sea as an element, with beaches, coconut trees, castles, etc., allowing users to experience the coolness of summer.




Of course, in order to cooperate with users to carry out independent DIY, a key puller is also distributed together with the keycap.





As for the keyboard, it adopts tofu color; it is wrapped with a light-colored ABS material bottom bracket in all directions, and the surface is frosted, which is very textured. A good fit for the keyboard, avoiding the fatigue of long-term use. Especially after laying the keyboard flat, it is extremely stable, and there is no light feeling of the membrane keyboard at all.




Because there are not many games in general, it is only used for regular office use, so in the selection of the switch body, I chose the red switch with a moderate percussion force. After all, there are more code words in normal times, and occasionally I play games. The operation is relatively easy, and it can also release the tapping feeling of the mechanical keyboard.





The keyboard takes the red switch as the core, which has the characteristics of short key travel, fast response, low pressing pressure and long service life; in addition, it supports hot swapping, which can be changed side by side. The standard specification key switch is also very easy to replace.




Of course, as a customized model, the Lofree mechanical keyboard needs to be installed manually before using the keycaps. The keycaps have been sorted before leaving the factory, and the user only needs to install the keycaps on the keyboard base according to the arrangement; The cap took about 15 minutes, which can be said to be a great exercise in hands-on ability.




The design style of the keycap is a round retro ball cap, and the PBT material is not only durable but also oil-free. Since the four corners of the keycap are chamfered by 0.65mm, it can effectively eliminate the cut feeling of the keycap, allowing the delicate texture to be reflected through daily operations.





The effect of installing the keycap is completed, and the overall feeling it brings to me is one word "Sa"! The color matching is amazing, with dark blue, light blue and other blue as the main color tone, with various summer patterns such as castles, coconut trees, beaches, sailing boats, etc., making this Lofree 100 keys deeply attractive out of my sight.






On the whole, the combination of summer invasion keycaps and tofu-colored keyshells, blue and white, gives people a small and fresh feeling. It is very suitable for the shopping style of urban young people.




In fact, I like this set of customizable mechanical keyboards, which can be reflected to a large extent through the keycaps and key shells, because it has very good compatibility with Windows and macOS, especially in details, such as the button next to the space bar, There are both Tian characters of Windows and alt characters of macOS, allowing users to switch seamlessly. For another example, the F1-F12 area adjusts screen brightness, volume, multitasking buttons, etc. Windows and macOS can be easily controlled.




The customized version of Lofree 100 keys adopts a 9° curve slope, which is more in line with the ergonomic design, especially for people like me who sit in front of the computer for a long time and type, and are very friendly. In addition, the switch/mode switching knob is located on the right side of the support frame, and the keyboard can be turned on when it is turned to the ON position. At the same time, after connecting the data cable to the computer, it can be used wired. After the gear is adjusted to 2.4G/BT mode , you can use it wirelessly.




Behind the keyboard support frame is the Type-C interface of the keyboard. If the user prefers the traditional wired keyboard method, he can use the built-in data cable to connect to the computer for power supply, without the need for additional batteries.




After nearly a week of comprehensive experience, the Lofree 100-key customized version gave me a good experience. It can be said that although it is a customized version, the whole installation process is simple and convenient, especially the hands-on assembly is quite interesting.




当然更重要还是键盘的功能体验方面，Lofree洛斐小翘100键定制版，采用蓝牙、有线的双模连接、出众的颜值表现以及出色的手感，无论是Mac用户还是Windows用户都能快速上手，无论是追剧&看电影打字，还是游戏过程使用，整个体验都非常不错。




Of course, users can also search for the "Lofree Building" applet through WeChat, and click "GO" to enter the optional interface of Lofree Luofei's main keycaps. What a happy and happy thing to have a mechanical keyboard of my favorite style.




After experiencing this, it is coming to an end! Lofree Luofei Xiaoqiao series has launched 68 shells, 100 shells, tofu color and cement gray 4 models. The theme keycaps include: social animal banana, Alice, migrant worker, street graffiti, cute cat, summer invasion plan, There are nearly 20 models such as Pharaoh’s Gold Parade and Good Luck Peach Blossom, which can fully meet the needs of different user groups for various theme choices. I believe that there are so many themed keycaps. When you actually touch the screen, you will find that there is always one for you.

The keyboard that is equipped with an office computer is really not suitable, and the film is fine, and it is also ultra-thin, so I really don't want to touch it. A while ago, I arranged a Greenlink low-axis wireless keyboard for my child, and it feels pretty good, so I paid attention to this brand again recently, and there just happened to be a low-key compact new model, arrange it and share it with the website.


The front of the package is a rendering of the product, with three-dimensional rendering.



The main parameters and features of the keyboard are on the back.



After opening the package, the keyboard lies quietly inside the inner protective panel. The accessories include a data cable, 6 replacement keycaps for mac system, a key puller, manual and warranty card.



The keyboard as a whole has a layout of 89 keys. The high-tech LP brown switch is short and the key stroke is short. The trigger is faster. The light sound design allows it to be used in a company environment or at home. The mechanical keyboard feels comfortable and labor-saving, but it will not affect others. .



The overall weight is less than 500g, which is lighter than a bottle of mineral water. It is very convenient to carry and expands its usage scenarios.


6° ergonomic angle, non-adjustable, slightly inclined is more user-friendly, and the four anti-slip rubber strips on the back can be very stable on smooth surfaces.



The indicator light is next to the ESC key on the top, and the TYPE-C port and switch are on the top side. Greenlink KU102 can connect 3 devices in Bluetooth mode, plus wired connection, 4 devices can be switched at one time (Fn+~ 1 2 3).


Bluetooth only supports 3.0 under the win7 system, and the system above win7 can support Bluetooth 5.0, with lower power consumption and faster response.



The center of the switch is off, and the connection can also be used at this time. Toggle left and right to switch the win mac system. If you are a mac user, replace the mac keycap in the accessory to bring an experience close to the original mac keyboard, which is very friendly to mac users.




The orange functional area on the right side of the keyboard adds screenshots, emoticons, lock the computer, sleep, search, and switch light effects. It is very practical and convenient to touch fish while working or working...



White backlight + light-transmitting keycaps, the visual effect is very eye-catching, supports 15 kinds of lighting effects and 4 levels of brightness adjustment, and has a wide range of applications.




Built-in 1800mAh lithium battery, the official battery life is 15 hours in backlight mode, and it can reach 180h if it is turned off. In addition, it supports intelligent sleep, enters the low-power mode without any action for a long time, touches it again to resume the working mode, and responds quickly.



Compared with conventional mechanical keyboards, the size is significantly smaller from the thickness to the height of the switch body. The conventional 4mm stroke, this switch body is only 3mm, so it feels lighter and optimizes silence.




The purchase experience of this Lulian KU102 thin and light mechanical keyboard is still very good. It is compact, light and portable, but there are also abundant shortcut keys for people to use in the case of 89 keys. The Gaote LP brown switch is short and comfortable to the touch. He is very friendly to himself and others, and it is not awkward to carry on a business trip. Give it a push~
