Newly emboldened by my ability to resurrect the PC that I'm using to post this thread, I've decided to see if I can resurrect an older gaming laptop.
I've got 'er all taken apart and I can see some issues, but nothing weird except for this.
On the heatsink there seems to be a piece of metal/plastic on the underside of the heat sink.
It's blackened except for two parts, the underside where it had been (very flimsily) glued with thermal paste, and the top side where there is a silvery rectangle in the middle of an otherwise charred looking outer surface. The rectangle mirrors the rectangle on the top surface of the chip where the heatsink paper stuff was touching.
So, what the heck is this stuff?
