" rel="nofollow - Hi all,

due to another isse I'm facing at the moment, I wanted to reset the CMOS of my Asrock Z170 Extreme 4:

- I unplugged the power, swapped the CMOS jumper for 10 seconds and set it back. Nothing, CMOS did not reset.
- Unplugged the power, pressed the clear CMOS switch at the I/O panel for 10 seconds -> Nothing, CMOS did not reset
- Unplugged power, removed battery for one minute and tried again -> Nothing, CMOS did not reset
- Unplugged power, removed battery overnight -> It worked, CMOS reset

Surely there mus be an easier way?
