Unplug system, disconnect battery. Hold the power button for 30 sec.
Remove the base cover and memory modules - reinstall.
Verify that the LED on the AC adapter is on before you plug in the notebook end. If it isn't, replace the adapter.
Plug in the adapter (no battery) - if the system will power up, but not with the battery installed, the battery is bad; replace it.
If it still won't power up, the mainboard is bad.
