last month upgraded ram in 2011 mbp 4gb 8gb using crucial memory. no issues whatsoever, figured more might better machine run little bit faster. returned 8gb , upgraded 16gb. after installation ran tests ensure memory working , passed. machine runs fine.

however, when close lid , machine goes sleep, not wake when opening lid. have press , hold power button , screen turn on fogged on (for lack of better description) , there row of tic tacs fill in @ bottom (see pic). once dots fill in nothing happens. need once again press , hold power button , manually reboot machine. not happen if leave lid open , machine falls asleep on own.
