Two times, I managed to get the keyboard working. I have no idea how (last time I was trying to hold the shift key when booting, but when I try now it does nothing).
When the Jumper logo shows up at the boot screen, on the bottom right corner there is a two digit number. When I received the computer, this number was 92, and everything was working smoothly. Right now, it starts by 98, changes to 92 for a few miliseconds, and finally changes to D7. When this happens, keyboard and mouse inputs (including external USB) do not work.
When I managed to get the keyboard working (where I got code 92), I resetted windows to a clean installation. However, after the reinstallation I started to get code D7 again. Now I’m back to square one.
Any ideas what this might be?
