Acer Aspire A515-51G keyboard not working in Windows, but works in BIOS

My laptop kept getting blue screen errors. After scanning for malware and updating the drivers using Driverpack Solution, the built-in keyboard stopped working. An exteral USB keyboard works just fine, but the built-in keyboard does not.

In Device Manager, under Keyboards, the only one installed is the USB keyboard (HID Keyboard Device). Showing hidden drivers does not reveal any other keyboard installed (I was hoping to see the Standard PS/2 keyboard driver). Also, there is no unknown device or anything similar in the Device Manager. I have also tried to do a battery reset, but it did not solve the problem.

However, when enetring the BIOS or the Windows repair, the built-in keyboard works just fine, so it is not a hardware problem.

Does anybody have any suggestions?

Check for an automatic WinUpdate "restore point" a bit before the time the keyboard stopped functioning. Jack E/NJ

I even reinstalled Windows (keeping the files, though) and it still didn't solve the problem. In the Windows instalation, the keyboard worked, afterwards it didn't.

Did you turn your router off during the factory re-set? Jack E/NJ

No, I haven't

It's the only sure way of preventing a Win10update. Once you're satisfied that an UN-updated Win10 factory-reset works OK, enable system protection before turning the router back on. By doing this, Win10 update should create restore points and we might be able to identify which particular Win10update is causing the KB issue. Jack E/NJ

Has anyone been able to fix this? I tried contacting Acer multiple times but they refuse to admit the problem and won't help me.

If it is still not working then we have to do a refresh and reset

Please try step by step. Try one by one. Try keep my files first, then remove everything - Just remove my files and then fully clean the drive.

click on start - settings - update and security - recovery - reset this pc - get started

or

on start - type here to search - type reset this pc - click on reset this pc on the top - click on get started

It will show you keep my files and remove everything

chose keep my files

chose the account - type the password - click on local reinstall - click on reset

It will be in progress..

login to computer and start using the computer.

If it is still not working

click on start - settings - update and security - recovery - reset this pc - get started

chose remove everything

click on local reinstall - just remove my files - click on reset

It will be in progress

Note:

If you do refresh ( keep my files ) - all your personal files like pictures, music , documents , videos will still be intact. Only the applications will be lost

If you do reset ( remove everything ) - you are doing a factory default. It will become like a day one computer. It will wipe out everything and take your computer to day one like a new computer.

You can also do the recovery in an alternative way..

There are two alt keys on the keyboard. If you look at the bottom row of keyboard you can see the one on the left side of space bar and the other on the right side of space bar. The alt key on the right side will be looking like alt, alt gr or alt car. Turn off the computer. Hold the alt key on the left and tap f10 continuously. It will go to repair mode. It will show you chose an option, continue, troubleshoot. If it is not going to repair mode, turn off the computer. Turn on the computer. Hold the right alt key ( alt gr or alt car or alt ) and then tap f10 continuously. It will go to chose an option continue and troubleshoot..

It will show you chose an option, continue, troubleshoot

Go to troubleshoot - click on reset this pc

click on keep my files ( only applications will be lost ) chose your account and type your password - click on local reinstall - click on reset

It will be in progress

If the keep my files option is not working

Go to troubleshoot - click on reset this pc – click on remove everything – click on local reinstall – just remove my files – click on reset

It will reinstall windows.

If the just remove my files is not working..

Go to troubleshoot - click on reset this pc – click on remove everything – click on local reinstall – Fully clean the drive – click on reset

It will reinstall windows.

Note: You can also go to chose an option , continue , troubleshoot by holding the alt key + tapping f10 or alt gr + tapping f10 on the keyboard while turning on the computer. Once you see the troubleshoot option, you can stop tapping the f10 and stop holding the alt key. Then you can try the keep my files and remove everything ( just remove by files and fully clean the drive ) by following the steps which was mentioned above.
