Hi again I forgot to ask this on the other message I'm sorry After I swapped in the 2300 system board something strange began happening. The system started booting itself with no one touching it. I'd perform a shutdown close the display and about 15, 20 minutes later I'd hear the startup chime and it would boot up. This only happens with the battery in place ac plugged in or not. Battery removed it doesn't happen. This never happened with the 280 system board, have I goofed someplace Thank you Gary
