Laptop keyboard stopped working on both Windows and Ubuntu after Ubuntu update

in flag

I installed ubuntu 20.04 LTS for the first time on my laptop a couple of hours ago and when I finished the setup everything was working perfectly fine. I was going to install some apps such as chrome and discord but ubuntu showed a message for an update and I decided to do it after I finish downloading.

So after I finished downloading, I went back to settings and downloaded the update then I clicked reboot. After the reboot my keyboard was not working at both login and desktop screens.

Then I booted back to windows (dual boot) and my keyboard was not working in windows too. I checked windows device manager and my keyboard was not showing up. So i checked show hidden devices box and the keyboard was there but it was saying that the drivers were not completely installed (error code 24). I tried checking for drivers but windows couldn't find one. On the Ubuntu end I don't know what to do.

p.s: External keyboard via USB is working fine.

Thanks in advance.

This sounds like a coincidence. There's nothing that could have happened in Ubuntu that would have affected the keyboard in Windows

Is your internal keyboard working in BIOS? If not, I personally think the cable might have come loose somehow.

If yes try these :

Can your check your xinput --list output and see if keyboard is showing up there ?

you can try these commands as well

sudo apt-get install xserver-xorg-input-all

startx

It's not working in BIOS too. I don't think it's because of the cable since the keyboard lights up. I also found out it works for a few seconds when i boot up.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
