Resolved Question

My keyboard doesn't work at all (HP ProBook 450 G4 )

Oct 9, 2018 2:47AM PDT

After putting my laptop to sleep 2 days ago, I opened it and the keyboard didn't work at all.

I tried:
- restarts
- system recovery to get before the last Windows update + again the previous
- to find drivers for the keybord, but there are none (only mouse, camera...)

According to this link, the keyboard was dead:

Luckily, this link gave me some hope:
https://www.laptopmag.com/articles/access-bios-windows-10
I chose "Factory Settings" in BIOS and the keyboard started to work.

BUT
BUT
BUT
When I put the laptop to sleep, after waking - THE SAME PROBLEM!

So again Factory setting...

WHAT SHOULD I DO?

Can anyone help, please?

Thank you!

It fails after sleep/wake. If you activate it again in the BIOS, does it fail also after shutdown/reboot and after hibernate/reboot? If those work, don't use sleep.

Does an external keyboard still work after sleep/wake?

Does a replacement internal keyboard still work after sleep/wake?

Hibernation works!

I tried Hibernation instead of Sleep and it works! Thanks! Happy

I know it will probably not be a permanent and ideal solution, but I have no time to nurse the laptop further. Sad

In the end the final solution was BIOS update - everything works as before. Happy

Try these troubleshooting steps that might help.

Try these troubleshooting steps that might help.
- Open Task Manager, press Windows key + R and type "devmgmt.msc" and press OK.
- In Device Manager expand keyboard and right click on the driver for keyboard then select Properties.
- Go to Power Management tab and remove the check on "Allow the computer to turn off this device to save power" then click OK.
- Reboot the PC and test it again.
- If that doesn't work go back to Device Manager then Uninstall the keyboard driver and reboot the laptop so it would install the driver back automatically.

No "Power" option
Oct 9, 2018 11:00PM PDT

This, unfortunately, I can't do, because there is no "Power" option at the keyboard
But it could be the thing, I guess.

I solved the problem for now by using Hibernation instead of Sleep. I know SSD doesn't like it, but what can I do...
