View Full Version : CMOS clear/reset - CG8580

Does anyone know who to reset/clear the cmos.
I made a change in uefi ( disabled fastboot and secure boot ), now system won't boot.

Cannot get into UEFI. Just a blank screen.

So I thought I would try clearing the CMOS. Is there a jumpber switch, some CG xxxx pc's have abutton on the back but the CG8580 does not.

Any advise would be appreciated.

try to remove the battery from the motherboard and disconnect the main power supply cord and wait for 5-10 mins and then put the battery back on the motherboard and then plug in the power cord and try to turn the PC back on
this should clear the CMOS
hope this helps
