> T42 Fan Replacement

A few weeks ago, the fan in my trusty IBM T42 bought the farm.  This resulted in the unit heating up considerably, as well as numerous "fan error" messages on bootup.  It eventually became so bad that to boot up at all, I had to blow compressed air into the fan's exhaust grill for 5-10 seconds, in order to fool the BIOS and make it believe the fan was actually spinning.

Since IBM didn't recognize the FRU that was required (13N5442), I ended up picking up a used heatsink / fan assembly from ThermalFX for $40.

IBM T42

The installation was fairly straight forward, except for removal of the GPU's thermal pad, which had essentially glued itself to the ATI chip.  I also oops'ed, and used a wrong screw when putting everything back together, which resulted in a small dimple on the palm rest.

I also took lots of photos.

Great post! The photos are very helpful. How did you end up removing the GPU thermal pad that had glued itself to the ATI chip? I'm having the same problem.
Thanks!

Great post! I have the exact same problem...! And indeed, how did you finally removed the thermal pad from the GPU??? I'd really like to know.

Thanks in advance
