✔ Best Answer

Have you tried changing the motherboard battery? On a desktop unit, it's a small circular battery that should be immediately visible on the board, usually lying flat, and can be removed with a small screwdriver.

The motherboard uses a tiny battery to store settings whilst the machine is off - without it, the machine will not store the BIOS configuration.
