Apple desktop computer refuse to boot
A friend of mine shut down his office computers yesterday only to arrive this morning to discover that 3 out of 5 Apple desktop computers refuse to boot. The sockets (power outlet) was also turned off, and no other person had access to the office.
We have checked the sockets and the cables, and they are ok but the computers refuse to boot.
Please can somebody please help as we are not professionals in this area.
