Needed to replace my thermal pase, noticed the heatsink had different size screw, I did take note of them but I think I mixed it up. Anyone knows where to get manuels for the screw sizes, I checked everywhere and couldn’t find anything.

Hi, Couldn’t find anything specific but maybe try inserting a thin wire into the screw mount to see how deep it is and then measure it for length. Looking at the screw sizes for another GA502 series laptop, all except one are M2 size screws (outer diameter of 2mm) with different lengths. The exception is an M2.5 (2.5mm diameter). Bit hard to measure accurately perhaps unless you have a vernier caliper.
