when you hit the power button the power light stays on for a few seconds and then goes off. The screen never flickers, no sound, nothing.
I have tried takeng the battery out and unpluging it from the charger, then putting the battery back in. still the same, then I pluged the charger back in, still no luck. Any clues?
Try reseating the memory. If that does nothing, is the LED on the AC adapter, ON before you plug in the notebook end? If it is not, replace the adapter.
If still nothing, the mainboard is faulty.
