Problem with Brother's Macbook, please help me...

[yoda13]

OK, my brother and I have the same computer...C2D Black Macbook purchased around Christmas...tonight he decided to upgrade his memory...calls me up and says his sleep light is blinking rapidly rather than pulsating when he restarts the computer and that is all it will do...I have him take out the new memory and put the old memory back in and this is still all the computer will do...

I had him follow step by step with me what he did, and it is the same way I did mine and is in accordance with the instructions that I found on Apple's support pages...

My question is two pronged but related: what does a rapidly blinking sleep light mean, and what exactly did my brother do to his computer?

I had him reset the PMU, zap PRAM, etc..

well according to this, their problem was the GPU, CPU or logic board and was summarily sent back to apple for repairs. I suppose it's possible that something worked loose when he was installing the RAM, but it would have to be at the breaking point to begin with.

Does he have apple care? Even if not, don't send it back with 3rd party ram as they will often claim that to be the problem and can't help you out... Which is BS. It's obviously not the ram... So have him return the ram to the original configuration and give apple a ring.

Sorry I don't have more info. Just my friend, Google.

Edit: After thinking a bit, the graphics on the MB are integrated, so GPU/Logic board is the same dealio I suppose.

Often this is because the new RAM really needs a thorough push until it clicks into place. Try pressing it harder into the slot until you hear the click and you should be able to boot up just fine.

Never mind if he has or doesn't have AppleCare. It sounds like the MB is about 9 months old so he still has the bundled warranty.

Yeah i think your brother just needs to push properly those things require a bit of force especially the MacBooks.

Sorry for the length to reply back...this is why I love this place...this turned out to be the problem...he didn't properly seat them...problem solved...I had forgotten the amount of force that they took to properly seat when I installed mine...anyway, thanks guys...
