Sony Vaio PCG-394L. powers up, bios posts, but constant beeping. if overheat, how to fix ? F2 can't enter bios. hard drive/ mem OK.
is there some way to undervolt it ? after bios posts, father reports it fails to boot with hard drive in place. also needs another hard drive.
is there a different key to enter bios ?
I would like to repair this myself i just have to have instructions as to what to do.
