I took my W510 apart this morning because Linux was issuing thermal alarms and
throttling back the CPU (i7-720QM). I'm glad I did because it has the infamous left-speaker
wire melting problem.

But, I've run into another problem: there are a bunch of small screws in the heat sink area,
including a few holding some small metal braces, and I can't get them out with the screwdrivers
that I have available to me. In fact, I've succeeded in damaging a few of the screwheads.

What kind of screws are these, and what is the best tool that I can use to get them out?

I've bought the Radio Shack branded versions of these and used them for years:

They are "good enough" for working on laptops. However, if you want the best, with better points, stronger alloy, and better handles, use Wiha:

I use Wiha slot screwdrivers working on microscopes, where they seemingly accomplish impossible removal jobs. Thanks to Wiha, I've never had to drill a screw.

Wiha has a sale going on, and I have a set on the way.

But, I suspect that the screws are being held tight by thermal effects
betwen them and the frame. A lot of heat is being generated in that
area. Would penetrating oil be effective is loosening them?

get the right screwdriver

ph1

sharp tap with hammer and turn very slowly generating alot of torque
It should open up.

Or you may need a left hand drill bit and drill them, and they should come undone.

Thanks, all.

Some Liquid Wrench and a little tapping did the trick!
Guess I don't need to use anti-seize when putting them back in.
