5739G Dead as a dodo

Few months ago my 5739G was overheating even when browsing so for the 2nd time since i've owned the laptop since 2009 i decided to open it up and reseat and put new thermal paste (AS5)

Cleaned all dust out the fan and heatsink and re-greased both GPU and CPU and put it all back together and it will not even turn on now.

When i plug the charger cable in, the power button lights up blue, but when you press it nothing happens at all.. no fans spinning no hdd starting up nothing.

Just wondering if you guys have any ideas?

I've already purchased a new laptop, Sony Vaio S Series top spec, i7 12gb gt640 2gb 256ssd etc, but even so, it doesn't seem to overpower the 5739g as much as i thought it would.

Nice bit of kit though, but i would still like to revive the 5739g ;-)

 

Some possible reasons:

1. Dead motherboard because of electrostatic discharge.
2. Dead CPU - same thing or killed by overheating.
3. Dead PSU - killed by overheating.
4. Improperly installed CPU (also will be killed).
5. Discharged battery for CMOS.

 

Did you attach the power buttons ribbon cable fully (if you had them out)? Or even worse, could be torn. Terribly fragile things. Even if you didn't have the buttons cover off, the cable could be a good place to start. Only a few screws hold it down anyway. Absolutely no power takes any chance of the static away, you can't stop a board from working solely from a static discharge...you also would have grounded yourself straight away through the heatsink. PSU is fine, hence the light when plugged in. CPU only goes one way. Doesn't take a brain surgeon to line a pair of arrows up, highly unlikely to be the CPU. And the CMOS battery wouldn't stop it either. More likely is a direct short possibly from the heatsink or screwdrivers, or as I mentioned the power button ribbon itself.
