    Hi... I just upgraded my MacBook Pro 15 (mid 2009, running Lion) memory from 4GB to 8GB. Kingston DDR3 1066Hz. It worked perfectly fine. But I noticed that screen goes off from time to time... Like it goes to sleep... When I press a button it wakes up to ask my password. Nothing really serious I guess, but annoying as well... Could that be from the RAM upgrade? Any ideas? Thanks...

    Does this happen when it's not plugged in? Check "Energy Saver" under System Preferences, the default is probably set very short if it's running on battery.

    um it sounds like a screensaver is on. does this happen when you're away for a bit? or while you're actually using the computer?

    Thanks for the replies. It happened once a day in the two following days. Once it did happen Using safari only. Not really sure if I was on battery, because I usually use the MPB in battery cycles. Just did some quick tests and don't think the problem is from a screensaver option. I'll try to experiment and keep an eye and let you know. Many thanks for the time to give a thought.

    what are your settings under Energy Saver - looks like a fluorescent light bulb? That is a different place than Screen Saver.

    Display set to sleep at 10min, computer set to sleep in 15 min. Thas's both on battery and on power adapter. All boxes checked, except for the "restart automatically if the computer freezes."
