Windows 10: Laptop in-built keyboard not working in Windows 10

Hello community:


I have a 7 year old Toshiba laptop (specs below) that originally came with Windows 7. I updated to Windows 10 Home about 3 years ago and all went well. Just about 2 weeks ago I boot my computer and suddenly the keyboard is not working. I shut down the computer by holding down the power button, turn it on again but this this time I enter the BIOS screen. In the BIOS the keyboard works perfectly, the arrow keys work, F1-F12 keys work, CAPS LOCK and NUM LOCK indicator lights turn on/off when pressed. I've tried all configurations in the BIOS to see if it solves the problem, including resetting the default configuration, but nothing works. As soon as the Windows 10 logo appears the keyboard stops responding. Interestingly enough, the CAPS LOCK indicator light turns on and it cannot be turned off when pressing. It goes off eventually and then the NUMS LOCK light does the same.


I've tried all standard procedures found in the internet, even mess with the registry. I've been able to solve other problems by following online tutorials, but not this time. Microsoft Tech Support remote accessed my laptop and did all sorts of troubleshooting but nothing worked. The keyboard drive in device manager is not detecting any problem, and it says the device is working correctly.


The problem, as I said, started 2 weeks ago and my Windows 10 Home version at the time was 1803. Windows never upgraded to version 1809. As part of trying to solve the problem, I did a complete clean install of Windows version 1903. The upgrade went well but the keyboard still doesn't work on Windows. A connected USB keyboard does work.


Please help. All the specs are here:


Toshiba Satellite P755D Laptop

Processor: AMD A8-3500M APU with Radeon(tm) HD Graphics 1.50 GHz

System type: 64 bit operating system, x64 based processor

Pen and touch: No pen or touch input is available for this display

OS Edition: Windows 10 Home

OS version: 1903

OS installation date: 6/1/2019

OS build: 18362.145


Thanks.

Built-in laptop keyboard works in BIOD but not in Windows

Since that is the case and even updating the device driver does not allow the built-in keyboard to work in Windows 10, we suggest that you uninstall the current device driver of the built-in keyboard. Doing this will allow the system to install a clean copy
of the device driver and correct any errors.

You can follow the steps on how to uninstall and reinstall the device driver for your built-in keyboard that is available through this

link. Refer to the last section of the article where the steps are indicated.

Regards.

Built in keyboard not working

I recently purchased an ASUS ROG GL553VD Notebook Computer and a few weeks ago the keyboard stopped working. After a few restarts it worked again, but today the problem came back, and was not fixed by any amount of restarting. Several people on past posts said to reinstall they Keyboard driver, but there was no Keyboard section in the Device Manager. I am currently resetting the laptop to factory settings to see if that fixes the issue. Any other suggestions would be greatly appreciated.
