Keyboard/touchpad stop working randomly


This has happened a lot since my upgrade to Windows 10, and it's really starting to get on my nerves. Seemingly randomly, my keyboard will stop responding to what I type, and my touchpad completely stops as well (no, I did not accidentally click to disable it). These problems will never resolve themselves on their own, but as soon as I reset the computer everything works again - to me, that sounded like a driver crash, but nope! I checked the driver menu and it told me everything was running just fine. What's even more strange is that I have the backlight keyboard enabled so that when I type, it lights up. And strangely, the keys still light up when I press them, so I know it's registering my typing SOME how.

You would also think that this would be a software problem since it fixes immediately upon reset, but I've noticed that this issue seems to crop up a lot right after I have moved my computer... I'm lost and I've scoured the internet for clues, but no one else seems to have this problem. Please help!

In order to possibly do testing on what is causing this (via suggestions hopefully, I've tried everything I can think of) I am purposely not resetting my computer (thankfully this is a touch screen, but this on-screen keyboard typing is obnoxious). Currently, both keyboard and touchpad don't work, but a usb mouse I use does (the computer is also set so that using the usb mouse does not disable the touchpad).

 

laptop keyboard and touchpad not working


Problem: computer starts up normally and goes to the password log-in screen, but nothing happens when I try to enter the password. The computer doesn't appear to see any keystrokes.
Solutions tried:

1. rebooted
2. removed and replaced main battery
3. attached USB keyboard
4. hit Enter key on startup: successful in opening the Advance Options menu, but am unable to take any of the actions because all require that I enter the laptop password
5. looked for an onscreen keyboard, but there isn't one because this isn't a touch screen computer

Why I think this is a Windows issue:

1. the computer recognizes when I hit the Enter key on startup
2. the USB keyboard doesn’t work
3. the keyboard touchpad doesn’t work, but the attached USB mouse DOES work

 

The "a" key has stopped working on my keyboard

Hi,

Keyboard issues might have been caused by an incompatible driver. For us to isolate the issue, we would like to know the following:

• Have you tried using other external keyboard?
• When was the last time that you are able to use your keyboard key properly?
• Have you made any recent changes to your PC settings prior to this issue?

In the meantime, we suggest that you follow the steps given on this article:
Mouse, touchpad, and keyboard problems in Windows.

We will wait for your response.
