I recently replaced thermal paste and gave the fan a clean on an overheating HP DV6 3131tx laptop. All went according to plan except when I finally put it back together it won't turn on.
Laptop receives power but it goes no further, the power button light (an HP Logo) blinks every 5 seconds.
Any ideas?
Can't give specific advice but you could look here (I think it's relevant to your model laptop).
