Dell Studio 1535 cleaning/disassembly

The temperature sensors on procyon [My Dell Studio 1535] laptop were constantly hitting abnormal values recently. CPU kept on idling at around 60C, even after my previous post on the fix for lm_sensors configuration applied. So I knew that it was time I opened the girl up and do her some good'ol fashioned cleaning. So I borrowed a cam, took out my toolbox, acquired some Thermal Compound [Shin-Etsu Microsi's G-751 Thermal Paste (thanks Shray!)] from a good friend, added some Pink Floyd on my playlist and got to work. Here are a few pics of the internals for anyone's viewing pleasure since I could not find any decent teardown images of the same model on the web. Enjoy....

After a thorough cleaning and application of new thermal grease, the temps have dropped significantly by at least ~10C

End result: a cool and quiet system and a wholly satisfied conscience :)
