I have ubuntu 18.04. The touchpad works an the power button works. I plugged an external keyboard and it works just fine
I have tried installing/reinstalling keyboard river but it didn't work
sudo apt install xserver-xorg-input-all
sudo apt install --reinstall xserver-xorg-input-all
I have also followed this link but it didn't work
UPDATES
so I honestly really don't know what's going on anymore. the keyboard doesn't work from windows nor the ubuntu liveUSB. I have gone to a professional to see it. they don't think it is a hardware problem because my asus keyboard has lights, and those lights work just fine. and according to them if it was a hardware problem the power button wouldn't work nor would the lights. I insisted on them to at least open and see and they did but found no problem in the hardware. I also opened it myself and tried to remove and insert the battery again with no results. The last thing i did was completely reformatting my laptop. it didn't work and the problem is still there :(
I just have no idea how this happened to begin with. I ran out of solutions from the internet. My last hope is one repair store that would take 3 weeks to look into the problem with very expensive fees -I have to pay 300$ just to open a request to fix it-
Update 2
I fixed it!!!!! I went to BIOS and clicked reset default and now it is working :D
edit: nevermind after rebooting it went back to not working
Update 3
I went to high-end fixing place, they changed the keyboard and it didn't work, they suggested replacing the motherboard, which costs the same as the actual laptop price so I refused. That's the end of my journey I guess, I will just use an external for a couple years until I finish studying then buy a better laptop once employed
