I just installed 4 gigs of ram and did it properly. I've done it before on my ibook with no problems. I went to turn on the MBP and it won't start up but the cpu is clearly running. The sleep light keeps blinking twice and nothing happens. I tried doing the install all over again and same result. Please help, any advice is welcome.
 
perhaps you have a bad stick of ram, try removing the sticks and try them out one by one to see if it is one stick in particular.
 
Try the RAM modules one at a time it's unusual (but not impossible) for both modules of a pair to be defective. Make sure the RAM is fully seated in the contacts before laying it down to the horizontal position. Your symptoms are still consistent with incomplete installation. What brand of RAM / what specs?
 
thanks for the quick replies... I'm using Kingston RAM 2x2 G sticks, pc2-5300. I will try each stick and try to isolate the problem.
 
its the value ram and it doesn't have heat spreaders. Is it possible it isn't seated properly. It felt like it went in snuggly but maybe I didn't push hard enough?
 
It boots but now I get a kernel panic on startup

Tried reseating the ram, I think that was the problem. It started up (twice?) and then immediately kernel panics. I'm not sure if I made progress or it just got worse?
 
Have you tried testing one chip at a time as i sounds like there is a problem. Does it happen if you put the original ram back in.
 
Glad you got it fixed, but man you're lucky you didn't ruin any ram slots if you had to push it in that hard.
