Reading http://support.acer.com/acerpanam/notebook/0000/acer/aspire4520/aspire4520sp2.shtml I see the same design as the doomed HP dv6000/9000 line.

Try the usual reset noted at the top of this forum and tell me how many Volts the BIOS BATTERY is reading.

Good luck and the usual fix is to swap in a new motherboard.
