Enter into the BIOS after power on with the F12 key. Search under "Power Management" "AC Recovery" and select "Power Off".
Expert advice please! After a loss of mains power, my 3020 tower PC auto powers up when power is restored. This is OK if during daytime, but it can & does happen at night. How do I set the PC to remain off after a power cut? Many thanks, Niloc1017
