Does anyone know which K6-2+ might be soldered and which ones just have thermal paste + silicone attaching the heatspreader? I'm trying to remove the lid on a K6-2+ 550 ACZ, datecode 0039BPMW. It's from a Sony Vaio laptop that had failed and I'm pretty sure it still works (worked?)
My olfa cutter blade made short work of the silicone, but the heatspreader is still attached. Could it be indium attaching it still?
There's enough resistance that I really won't want to pry it...
Use the shaving razors I showed in previous post. Also, others have said acetone can help.
Be sure to reinstall the spreader. Don’t want to have a accident with the die.

Thanks for the screenshots and applying a little heat sounds like a great idea, thanks for sharing. I'm also interested in seeing some numbers for your 550ACZ case if you're thinking about posting them. 😀
I’m going to eventually make a difinitive guide here showing how to take the lid off with no risk, and reinstall it in a way that looks factory.
I’m still working out the details,
But so far what I have is this:
I think acetone, and a shaving razor is the way to go, no heat. I think the heat may actually hurt at the levels required
The material used for the adhesive is still a mystery to me, but it may be urethane.
I’d like to recommend a thermal adhesive for the die but I can’t seem to find artic silver thermal adhesive these days.
Also some sort of 3d printed guide needs to be made for installing the spreader in one motion to avoid the adhesive smearing.
Can someone whip something like this up?
