HELP: Stuck processor

So my bro finally broke down and let me clean house on his laptop, both through the OS and by physically opening up. Everything was swell until I took the heatsink assembly off. This is a Dell Inspiron 5100 with an actual desktop 2.4GHz P4 in it, the thing gets hot and the HS is massive. However, dust had completely blocked the airflow in the HS and the processor got so hot that it basically baked the TIM onto the IHS of the CPU. I ended up pulling the CPU out of the socket when I pulled the HS off. Now I have to somehow get them unstuck. I have never come across a processor so stuck as this one. I'm using 91% isoprophyl alcohol to eat around the edges while using a razor blade to pry it off. No go so far. What else do you guys recommend, freezing it? Thanks alot for quick replies.
 
You could freeze it, though I don't know enough about doing that to suggest it. Though it seems I just did. :p

You could use GooGone too, though I don't know enough about doing that to suggest it. ;)
 
i have heard that you should use the comp for a few minutes to heat up the proc and get the TIM in a more "liquid" state so the heatsink would come off easier

That is true. You should do the same thing for AS5 also on desktop CPUs. It will all but eliminate the "pulling the CPU with the HSF" syndrome.

you sure they didnt use epoxy on the heatsink?

More than likely you are correct. If the CPU was epoxied onto the HSF, the best way to remove it would be to put it into an anti-static bag, then put that into a zip lock bag, and put it in the freezer for 30 minutes or so. After you remove it from the freezer, the CPU and HSF should seperate with minimal effort. Manufacturers (especially of laptops) don't like you going in and messing around with the hardware. They will usually tell you that if you open certain parts of the laptop case, or remove parts, even if it is just for cleaning, you will void the warrantee.
 
The day I respect any warranty is the day I stop working on computers :p

Nah, this thing is 2 years old anyway and the warranty has run out, so no worries. I can't run it and then shut it down because it takes a good 15 min. to disassemble the laptop enough to safely get the CPU out. I did put it in a ziploc bag and freeze it for a half hour and with a little prying from a flat head, it came off. Seems like they just used some lithium grease. The problem came from the high heat baking it on. Anyway, fast forward an hour and I bent the pins back to their originally positions (bent from being torn out of the socket), AS5 is on, the HS is totally clean, and now the laptop is running SILENTLY :D and defragging. Joy! Thanks for all the help guys, that was one sticky situation (lol @ bad pun :p)
