I'm currently in the process of rebuilding a computer from Alienware computer pieces. The motherboard itself is 046 MHW, and on boot it gives 5 beeps without any actual booting. This indicates a Real Time Clock failure. I have tried replacing the battery AND resetting with jumpers... nothing. Google doesn't seem to be able to suggest anything additional, either.
Backstory: Computer was disassembled and brought overseas in a suitcase and is currently attempted to be reassembled.
