Replacing Power Jack in T42, and tips/tricks?

[fefrie]

I just replaced the sxga cable restoring the lid switch capabilities.

Surprisingly not much of a bad job. Pretty easy. Took apart the bezel and keyboards, and left the hinges of the screen attached.

Now I have to replace the power jack.

Any precautions?

Will I have to buy thermal paste? Do I have to put thermal paste on the gpu?

Thanks for the help!
