Is there a fix for damaged stuck screws?

Great machine until I upgraded to Maverick. So sluggish and iPhoto and gmail a mess. Did my homework to add ram. Used your website to know what I was doing.

First 7 screws came out easily. Bottom left three won't release no matter what size Phillips head I use. They look damaged. My computer has never been anywhere but my desk! But these 3 screws look damaged and won't budge. Obviously I can't force the back lid off to install my ram. Is there any solution to this or must I do crazy expensive repair at Apple or Tekserve? My 3 year service plan up last week. Thanks for any suggestions

Apple uses a thread-seal on the screws to prevent them from loosing up. So you do need to be careful you don't strip the heads. I've found a heavy-duty soldering iron can heat up the screw enough to soften the thread-seal for a second or two. Give that a try otherwise you'll need to try a little solvent - dampen a cotton swab (Q-Tip) with some methylene chloride and the screw it may take a bit of time to get enough to get down to the thread-seal (don't soak it!).

If that fails your last choice here is to carefully drill out the acre head and then using a pin vise remove the rest of the screw or slot the top of the screw shaft (after popping the cover off and masking off the area).

Sorry you couldn't fix it your self. If this answer answered your question please remember to rate (score) and mark it accepted.


Thanks Dan for your knowledgeable response! What you describe is beyond my toolbox and expertise so I need to drop it off for repair. I do think the three damaged screws happened the two times I left it for repair at Apple and I never noticed until I went to loosen them.
