when I boot into my ubuntu it is very slow. In ubuntu it keeps typing the lower case of letter "o".
I wanted to update my BIOS, but there is no chance as I´m using Ubuntu and the BIOS-Upgrade ist only available for Windows. I tried to install Windows 7, 8 or 10 but the Laptop freezes while trying to start the installation (rotating circle). I let to boot it overnight, but it is still stuck at the same screen. Even booting WinPE does not work, stucks at the same point. I guess, the reason is the continuous typing of "o".
I unplugged the internal keyboard and attached an external one. But this didn´t solve the issue either.
