Disconnect the adapter and battery and press and hold the power button to release any static power.
Remove and reseat the memory modules and check if the system powers on only with the adapter connected.
Disconnect the HDD / ODD and check.
As a last resort, remove and reseat the CMOS battery and check if the system powers on.
If nothing works, then I would suspect a failing motherboard.
