VAIO PCG-K25 won't boot after applying thermal grease...Help!

Long story short, my Vaio PCG-K25 was continually burning my legs and would simultaneously idle as loud as a school bus, so I decided to crack it open, clean out the dust, and reapply thermal grease to the heat sink. After carefully opening it, scrubbing off the old grease with isopropyl and applying a small layer of dynex thermal grase, and reassembling the machine, I nervously tried to boot the machine.

The machine LEDs light up and the fans sound like they're spinning, but there is no monitor (or apparent HDD) activity...grrr. Could I have screwed up the whole machine just by reapplying the thermal grease? I was very careful with the machine and have no idea what could be wrong. I've tried booting with just the AC adapter, just the battery, and a combo of the two. This VAIO has only given me multiple problems since I've had it, but I don't have the money to afford Sony's wild repair charges or a new laptop. Any tips would be appreciated, thanks.

 

Make sure you have seatedthe processer in the socket correctly. I understand you have performed the procedure carefully, so I assume you wore an anti-static wristband, or something to the same effect. If you didn't, this may be the problem, but it is unlikely. Also, make sure the hard drive is correctly connected to the motherboard, if there is no hard disk activity. Hope this helps.

 

Update: Upon opening the machine, I see that when I press the power button, the fans rev on for a second and then cut off...I was actually able to get one of the fans to power consistantly on by varying the amount that the whole cooling mechanism is screwed in. It has three spring screws labeled 1 2 and 3.

Anyone?

 

bump?

 

Try reseating the processer. That is to remove the processer (and cooling system) and then insert the proccesser into the socket again. It may not boot because the motherboard may not be recognising the processer properly, or at all. Hope this helps.
