After waking from sleep, my HP P laptop keyboard doesn't work, and I have to restart

[gajah2555]

I have been trying many steps from the internet to get this resolved.  But nothing has worked.

• External keyboard and screen keyboard work, but after logging in, laptop keyboard still doesn't work.
• I have reloaded the relevant drivers
• I have checked in the device manager that the box is checked so the keyboard can wake the computer
• I have repaired the registry
• I have tried Windows Startup repair with no messages
• I have performed multiple disk scans using sfc /scannow, says everything is OK
• Twice I have used the Reset this PC function, keeping the personal files.  This didn't work.
• I also tried the in-place Windows 10 reset, as directed by Microsoft chat, but no change
• I don't want to reinstall Windows, since I have so many personal files I will have to reload back on.

Do you have any other ideas that my work?

Hi! @gajah2555, Welcome to HP forums.

I understand after waking the PC from sleep the keyboard stops functioning.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your laptop?

Have you tried checking with an external keyboard?

Are the keys on the keyboard physically stuck?
