I used this guide plus the Thermal Paste guide to resolve my MacBook RRS (Random Restart Syndrome) issue. My MacBook would randomly restart after the fan kicked into high speed. When I removed the heatsink I discovered an an irregular patch completely free of thermal compound of about 15-20% of the area on one of the processors. I removed and re-applied the thermal paste. I ran a memory test utility overnight that previously caused a restart after a couple of hours, and the probelm seems to be solved. TIme will tell.

This guide was seriously helpful, so thanks for putting this together. I found a thick ribbon of dust/muck whatever between the fan outlet and the exhaust port that was almost as dense as felt. My fan must have been fighting like crazy trying to pass air through that blockage, which explains the high temps and excessive fan noise. Wish I'd done this sooner...

Thanks again!

Just R&R'ed the fan in my black MacBook Core 2 Duo tonight. Took me 30 minutes tops and I was taking my time. These instructions are SPOT ON! Great job! Two thumbs up!

Follow the instructions exactly as you see and have a piece of paper taped to the table next to you that you can outline all the screws you took out so you know where they go back in. I expected this to be a LOT harder, but it was one of the simplest repairs I've ever done to ANY computer!

Piece of cake--or should I say gum. If you don't have a magnetized screwdriver, load up a stick of gum and chomp on it until it's needed then use a bit to retain screw on the driver. And if you should tear the black tape, or if the silver tape won't stick any more, just bubblegum it together. The instructions were clear and correct, which made for a very simple repair.

Will not drop out even if you turn it upside down?

Somehow, now my isight camera doesn't work and the light is always on. Cannot figure out what I did wrong.

Somehow the plastic disc with the slot for a coin got dislodged from the case, and I can't seem to get it open now. Any tips/links on how to open this without the aid of the plastic disc?

howard bederman,

My computer will not charge when plugged in. It will stay on as ling as the plug is in the wall however if the power source gets disconnected it will shut down immediately. I removed the battery and put it back in that did not help. It worked and charged fine 2 days ago. I have a backpack with a laptop storage area. I went to hang the backpack up and it fell and ever since the battery is not functioning. Is there some fix I can try or is my only solution to replace it? I would have thought that dropping it would affect more than the battery?
