Hi there. I have a Sapphire mini-pc. Now it is unusable as I unfortunately disabled INTEGRATED GRAPHICS in the CMOS. I was trying to solve a graphics-related problem on the last version of Ubuntu and I was following a guide. Now the pc turns on but I can't see anything on my tv attached via hdmi cable. Can you help me? I also opened the case, sconnected and riconnected the battery but nothing happens. I can't find a jumper that resets the CMOS. How can I solve this big problem? Thank you in advance for your help.
