The laptop keyboard and touchpad are not responding. What should I do if I can't use the external keyboard and mouse?

Answer: There are hardware reasons for this situation, as well as software reasons. There is a high probability of a malfunction on the part of the software.

When dealing with the matter of quick resolution, I would like to give the following suggestions.

1. Check for software problems.

Restart the system first to see if it can return to normal. If it works, continue to use it. If not, go to the next step.

Recall what important things you did before the failure. It may be caused by your operation, such as uninstalling the keyboard, mouse driver, and serial communication driver (U port). It can be solved by restarting.

After restarting the system, some or all of the keyboard and mouse drivers will be automatically restored and ready to use. Of course, it is also possible that the driver will fail to load. When connected to the Internet, most systems will automatically load regular device drivers and automatically restore the functionality of the keyboard and mouse.

If it fails, go to the next step.

This step requires recovering the operating system. If the system doesn't have important software, such as financial software, etc. You can consider restoring your system, of course, before you have a backup.

Otherwise, let's reload. After reinstalling the system normally, the function of the keyboard and mouse cannot be restored. Go to the next step.

Hardware checks. Second, check for hardware problems.

Reboot the system into the BIOS, it is not possible to operate with the keyboard, if it can be operated, go to the next step.

Insert the USB flash drive with PE bootability, after starting PE, try to operate with the computer's touchpad and keyboard, if you can. Replace your operating system. If not, your computer needs to be disassembled.

1.What to do if your laptop, mouse, and touchpad don't work.

If the touchpad is broken, it may be that you turn it off (disabled) by default, and you can open it in the control panel.

If the mouse is broken, if it is wired, it should be poor contact, if it is wireless, it should be that the battery is dead, provided that your mouse is not broken.

First, make sure that you haven't inadvertently turned off the touchpad. Multiple key combinations may turn the touchpad on or off. Typically, the touchpad turns on and off with pressing the fn key (usually located in the bottom left corner of the keyboard) while pressing other keys.

What other keys can cause the touchpad to turn off? Although it may also be other keys, the most likely one is one of the function keys (f1-f12). Look at the keyboard, especially the small icons (usually blue) on some of the function keys.

Pay attention to the icons that indicate the status of the touchpad.

2.The keyboard and touchpad of the laptop are not used when there is no reason.

If the drive is not installed, it will be like this!

Find a professional to get it!

It's not that you can reinstall the drive and you'll be fine!

The consequences of choosing the wrong step in the drive are not the same!
