Problem with new memory

I bought a black MacBook back in February: 2 GHz C2D, 1 GB RAM. After reading here about the sale on Crucial memory at NewEgg, I took the plunge and bought 2 GB. Installed it last weekend, and everything was great. Until today.

I took the laptop to work as usual, shut the lid at the end of the day and brought it home. When I opened the lid, the screen remained blank, although the little white "sleep" light came on. Turned it off and on a time or two; nothing happened.

So I got out my manual and one of the suggestions referred to new memory. So I uninstalled the new, reinstalled the old and bingo! Booted up just fine. Uninstalled the old, reinstalled the new, and nothing. So I'm back to the old 1 GB of memory.

If it worked fine for 4 or 5 days, do I have a problem with the quality of the sticks? Or could I be doing something wrong with installation? Any other ideas about what could be wrong?

Thanks.

 

I recently upgraded my ram to for the same type of macbook, It's weird that it worked for that short period of time and then stopped, maybe the ram slipped out of place and you didn't have it in far enough, I can't really think of anything else..btw I also bought mine at newegg

 

That was my first thought, but it seemed to be well seated. And I got the original memory back in and working - although maybe it will quit on me next week.

 

I had a similar problem. It may look like it is well seated, but it probably isn't. Firmly seating the ram in place solved my problem.

 

yeah check the manual or online for specific instructions, but the ram must be seated while it is still at the angle, before it is pushed down and fully locked into place.

I think it is more likely that the RAM is bad than it coming out of place. good luck.
