I decided to tear apart my laptop, a Compaq CQ61, and replace the CMOS battery and clean the heatsink off. After I removed the heatsink I tore the thermal pad and thought it would be OK to just use Arctic Silver on the GPU and CPU. After I put it back together the laptop kept shutting off randomly. I had a feeling it was the GPU so I dug my old XFX HD 4890 graphics card gathering dust out of the closet, and took the heatsink off and cut out a square of thermal pad off one of the Vram and placed it on the laptop's GPU. Now it's running fine, so I'm a little curious why the heatpipe isn't attached more securely so that you can use thermal compound instead of a thermal pad on the GPU.
There is almost no tension on the GPU heatsink at all.
