Just talked to Dell support and got it resolved. I needed to download the latest BIOS from Dell support resources and install it. It took several minutes to install, restarted the laptop and now everything seems OK. (keyboard is working properly)
Recently i've installed a BIOS update to version 1.12.0 via Dell Update application. The update finished as intended, there were no issues and the PC rebooted succesfully. However, I noticed that my keyboard doesn't respond to my actions and doesn't work at all (even though the drivers are up to date and I've tried uninstalling/reinstalling them). Right now the only way for me to type is to enable a screen keyboard and/or connect another one via USB . Besides , I've noticed that my PC charge percentage doesn't change when plugged in (it stays at 18% and goes into power saving mode when unplugged). All of the above issues started as soon as I updated my BIOS version. Is there any way to fix them?
