The memory modules have tested.
With the power supply disconnected, hold in the power button for several seconds.
Verify that you have a led on when you plug in the power supply.
If the power led is not lit then your laptop power supply may be faulty.
If the led is lit and you hear no disk activity or have no bios display then your motherboard will require repair or replacement.
