Hello:
I have a C640 that has been working fine. Yesterday, I switched it off normally and when I power it up, it doesn't boot. All the lock LEDs ( on the top of the keyboard) and the 2 LEDs on the side ( Power On and Hard disk), stays on solid for a 4-5 seconds and then everything dies. I searched these forums but couldn't find any information. What could be the issue?
I tried using battery alone, outlet power alone and both, without success. Both the battery and the power adapter works fine with another C610 I have, so they are not an issue.
Thank you very much.
Raj.
