The mouse is an input device for computers and an indicator for positioning the vertical and horizontal coordinates of the computer display system. It is named after its mouse-like shape (called mouse in Hong Kong and Taiwan). Its standard name should be "mouse", and its English name is "Mouse". The use of the mouse is to make computer operation easier and faster, replacing the cumbersome instructions of the keyboard.
3. How to restore the keyboard and mouse that are useless after reinstalling the computer system?
Method 1 1. Restart the computer first and press the shutdown button to shut it down (not force shutdown). 2. Then turn on the computer and press the F8 key (the keyboard will definitely be usable at this time), and then go to the advanced startup options and select [Safe Mode with Networking]. 3. At this time, boot into safe mode. If the USB mouse and keyboard are also usable, they are connected to the network. At this time we just need to update the USB driver. 4. Finally, after the update is completed, the USB can be used after rebooting to normal mode.
Method 2:
Check if your computer interface has an old-fashioned mouse interface, that is, a PS/2 (round port) interface. If so, use an old-fashioned mouse interface, and then install the USB driver. .
4. After reinstalling the computer, the keyboard and mouse cannot be used.
1. Press F8 to enter safe mode after booting, and then exit. Normal mode (repairs registry).
2. If the fault persists, please use the system restore that comes with the system to restore it to the time when the fault did not occur (if the normal mode recovery fails, please turn on the computer and press F8 to enter the safe mode and use system restore).
3. If the fault persists, use the system disk to repair it. Open the command prompt and enter SFC /SCANNOW and press Enter (there is a space between SFC and /). Insert the original system disk to repair the system. The system will automatically compare and repair it.
4. If the fault persists, it is recommended to reinstall the operating system.
5. What should I do if the mouse and keyboard are useless after reinstalling the computer? It depends on whether your current system can be used. If it can be used, when you turn on the computer, you can see whether the keyboard light is on. If it lights up, it means the keyboard is not broken. Check what interface it is. It may be a little slow to start the system. Try waiting for 2 minutes for the system to load. If it doesn't work, use the method below. :
2. Open (OPEN) the case and discharge the CMOS.

Open "E00E0804", you can see the "Layout File" sub-item in the sub-item on the right, double-click to open the item, change "kbdus.dll" in "Numeric Data" to "kbdjpn.dll", "OK" that is Can. By analogy, you can change the "Layout File" in all subkeys ending with "0804" to "kbdjpn.dll", depending on your commonly used input method. Then restart the computer and it's fine! There are many reasons for laptop keyboard failure. The more common ones are the ones introduced to you at the beginning. In addition, some viruses can also destroy computer keys. It is recommended that if you encounter laptop keyboard keys failure, you should first disinfect the computer. Use the above method later. When the computer starts up slowly, we can do the following steps; after the computer keyboard fails, it is recommended to transfer the keyboard to another computer for testing. If the keyboard fails, please repair or replace it. If there is no fault, please repair the system. Computer keyboard failure repair steps 1. Turn on the computer and press F8 until the advanced options appear. Release it, select "Last Known Good Configuration" and press Enter to repair. Computer keyboard failure repair step 2. Press F8 to enter safe mode after booting, then exit. Select restart or shutdown to boot, and then you can enter normal mode (repair the registry). Computer keyboard failure repair step 3. If the computer keyboard failure persists, please use the system restore that comes with the system to restore it to the time when this failure did not occur (or use restore software to restore the system). Computer keyboard failure repair step 4. If the computer keyboard failure persists, use the system disk to repair it. Open the command prompt and enter SFC /SCANNOW and press Enter (there is a space between SFC and /). Insert the original system disk to repair the system. The system will automatically Compare and repair. Computer keyboard failure repair step 5. If the computer keyboard failure persists, set the optical drive in the BIOS as the first boot device, insert the original system installation disk, and press the R key to select "Repair Installation". Computer keyboard failure repair step 6. If the computer keyboard still fails, it is recommended to reinstall the operating system. (1) If the computer cannot detect the keyboard after starting up, you can first check whether there is a problem with the keyboard interface. Because it is the most convenient to check without having to disassemble the keyboard. First unplug the keyboard cable from the chassis, then plug it back in, and then turn on the computer to see if the fault disappears. This can rule out computer keyboard failure caused by poor keyboard interface contact; if there is still a problem, you can use a multimeter to measure the keyboard on the motherboard. interface, if a certain voltage of the 1st, 2nd, and 5th core is measured to be 0 relative to the 4th core when turning on the computer, it means that the connection is broken, just find the breakpoint and reconnect it; if there is no problem with the interface on the motherboard, remove it. Open the keyboard and check whether the keyboard fuse is normal. If not, replace it. If it is normal, use a multimeter to measure whether the voltage at the keyboard cable connector is normal. If the voltage at the motherboard keyboard interface is normal but not here, it means there is a break in the middle of the keyboard. Cord, replace the keyboard cable to repair the computer keyboard failure. (2) Troubleshooting method for failure of a computer keyboard when a certain key on the keyboard cannot spring up after being pressed: The reason why a certain key on the keyboard cannot spring up after being pressed is due to the aging of the springs under some keyboards and keycaps, which weakens the elasticity, causing The spring is deformed, causing the contact to fail to separate in time and thus fail to spring up. The fault repair method is: replace the spring under the keycap cover, or slightly stretch the spring to restore its elasticity, and then reinstall the keycap. (3) Troubleshooting method for computer keyboard failure and no response on the screen when pressing a certain key: There is no response on the screen when pressing a certain key. The main reason is that there is dirt on the internal circuit board, causing contact between the contacts of the keyboard and the contacts. Defective, causing the button to malfunction or the spring inside the button to be aged and deformed, resulting in poor contact. The fault repair method is: first dismantle the shell of the keyboard, use a soft brush to remove dirt from the circuit board, and use absolute alcohol to clean the part below the keyboard keys that is in contact with the keycaps, and then test after cleaning. If the fault persists. Then disassemble the keyboard shell again and replace the problematic keys.
After reinstalling the system, the mouse, keyboard and USB disk cannot be recognized. It may be caused by the mismatch of the USB driver of the 100 series motherboard.
Solution 1. Restart the computer first and press the shutdown button to shut it down (not force shutdown); 2. Then turn it on again and press the F8 key, then go to Advanced Startup and select [Safe Mode with Networking]; 3. Now boot to Safe Mode mode, update the USB driver, it is recommended to use 360 Driver Master or Driver Wizard; 4. Finally, after the update is completed, restart to normal mode. Ready to use.
Thank you. In fact, I often encounter USB devices including keyboard and mouse that all fail under WIN10. The main reasons are: 1. Computer Low hardware configuration causes slow system speed, mainly due to temporary driver failure caused by too slow hard disk speed. Restarting the system can generally solve the problem. It is recommended that the system and driver software be installed in a good quality SSD hard disk;
Second, the USB port power supply is insufficient or If you bring a lot of equipment, especially the Corsair RGB keyboard with a lot of lights, if you use it with other RGB headsets and mice at the same time, it is easy to have insufficient power supply and unstable equipment, causing temporary malfunction of the equipment. Generally, this can be solved by re-plugging all USB devices and the system will beep. If it still doesn't work, it is recommended to equip the computer with a multi-USB port hub with an external power supply of 24v or above. In addition, it is recommended to lower the light brightness of the device appropriately during daily use;
Three, if it is the fault of the keyboard and mouse itself, such as the keyboard USB cable Or if the PCB has a weak solder or an open circuit, you will need to contact after-sales service or find a professional to repair it.
Fourth, if there is a problem only with win10, it may be caused by the compatibility of the USB driver of this model of motherboard under this system. You can only change the system or wait for system patches or motherboard driver updates to fix the bug.
