Was the battery and charger out at that time?
I turn the power on and the keyboard lights and the CPU fan turn on for about 3 to 4 seconds then turn off. Then there is a few second pause, and the keyboard and fan turn on again for a few seconds and then turn off. Nothing ever shows up on the screen.
I have disconnected the battery and tried to power on with just the AC adapter and get the same results. I have held the power switch down for anywhere from 5 seconds to a minute, no luck. I tried to power on just with the battery and no AC adapter with zero results.
Frustrated and ready to go gamble to make money to buy a new laptop. (or lose what little I have!)
