I removed the HD and hooked up to a Desktop PC and it is working and all files are visible.
Don't even get a flicker on the screen and when the keyboard was removed to re-seat that memory the fan isn't visually energized either.
To rule out just about everything but the board, remove the battery and unplug the system. Hold the power button for 30 seconds and reseat the memory modules (remove and reinstall). Try without the battery (adapter only). If the system will power up, the battery is faulty. If it won't, the mainboard is bad.
Try these steps in order:
- Remove RAM from outside slot (DIMM B) and reseat
- Remove internal Bluetooth card
- Remove RAM from inside slot (DIMM A, under keyboard) and swap with DIMM B
- Remove wireless card
- Replace coin cell battery
