Question Acer laptop keyboard does not work after resuming from Sleep mode

[punk12345]

Dear Friends,

This is my first post to this forum. Since recently my laptop keyboard is behaving strange.
The keyboard does not work after resuming from Sleep mode. It never used to do this earlier.
I have the latest drivers for the keyboard. i even tried uninstalling the drivers and let windows install it, still no luck.
I noticed that after resuming from Sleep mode, in the device manager, the keyboard component shows a yellow exclamation for the Standard PS/2 keyboard.
However, once it restart the laptop it works fine.
I have provided my system spec below. Any help or suggestion to fix the issue is greatly appreciated. Thanks in advance.

Update your BIOS. Installing the latest BIOS version can sometimes fix hardware-related issues.

Firmware for this older system can be found here:

Is your Windows installation fully up to date?

Thank you very much, friend. You read my mind, I was going to ask where to search for these BIOS updates.

By the way, my Windows is up to date. Thanks.

Thank you for pointing to the BIOS drivers. I found out that the BIOS drivers listed in the website is v1.37. When I checked my version I found that I already have the latest version of the BIOS installed on my system :-(

Is there anything else I need to do to fix my keyboard issue. Please advise. thanks.

What, if anything, did you change or install just prior to this problem occurring?

Does this happen with an external keyboard attached?

One thing you could try is going into the device manager, right-clicking on the Standard PS/2 keyboard, and selecting "Update driver" to see if that helps. If the issue persists, a workaround for now could be to restart your laptop after waking it from Sleep mode. It's not ideal, but it might keep you going until we find a proper solution.

Also, try SFC and DISM:

Tried updating the driver. Not helping. Same problem. Thanks.

Do you recall where you downloaded Avast from?

From the Avast site. I can try uninstalling it temporarily to see if it will help.

By the way I bought a new USB keyboard and it works. But it is a temporary work around.
