Keyboard and Touchpad not working

[MKC5527]

Hi - I had to unplug the battery earlier today. When I plugged it back in and turned on my laptop, my keyboard and my touchpad are no longer working. 

I did not disconnect them initially, but I did double check and make sure everything is connected ti the system board properly. 

After many unhelpful “my keyboard isn’t working” threads where the solution was “restart and press esc/F10” which I obviously can’t do because my keyboard isn’t working, I went to settings>advanced startup and after I entered UEFI - my keyboard was functional. However when I launched the computer as normal it wasn’t working again. 

I have done the HP PC tests, failed the keyboard and the touchpad tests because, obviously, they aren’t working. 

I have gone in Device Manager and searched for drive updates, there are none - I am apparently running the best driver available. 

I have disabled and enabled the devices, changes nothing. I have uninstalled the and restarted my laptop, changes nothing. 

In the advanced options startup I have not tried the Uninstall Updates or System Restore yet. 

I do not want to reset my laptop. I don’t want to have to redownload every thing. 

Again, HP Envy 360x 13-AP0013dx - Windows 11

I also did a system restore to a point almost 24 hours ago and still no change. 

PS - I do not own an external keyboard or mouse that I can plug in. But since the keyboard works in BIOS it shouldn't be a hardware issue.

For anyone checking this post out - I finally fixed it. 

I went to the “Optional Updates” section and just downloaded and installed every single one. Three of them required I restart my laptop, when it booted back up it began installing a BIOS firmware update. Once that completed and I got logged back in my mouse and keyboard were working again. 

I have been having an issue the last week with the cursor moving around my screen, sporadically jumping from place to place when I try to click on things. Maybe this solved that issue as well but I’d much rather have a jumpy mouse than no mouse at all!
