2. Remove hinge covers (if you can) and keyboard. Disconnect all cables under the keyboard.

Yes, it can cause the problem. It’s likely the laptop shuts down because the chip overheats.

i would have to re-attach this part through memory bay
as i cannot find a disassembly manual

I’m not sure you can do that though the memory bay. Most likely it will be necessary to remove the motherboard in order to reattach the heatsink.

he was changing the memory when he saw a heatsink loose
now when the laptop boots it shuts itself off straight away
i can get into bios but before i can make any changes it shuts itself off the part that came off was attached to SiS M661FX
chip would this cause it to shut off prematurely and how would
i re-attach it with adhesive or thermal tape ive uploaded a picture of it thats it just above memory module (striped thing) when you zoom in
http://www.megaupload.com/?d=D0QCNS5U
any help? i would have to re-attach this part through memory bay
as i cannot find a disassembly manual anywhere which makes me wary of using tape as i dont think i could position it accurately
Help!!!
