    I picked up a used MacBook Pro a while ago and immediately replaced the HDD with a 1TB SSD and maxed the RAM. I only turned it on once before hand to run a hardware test which came back okay. It often (almost all the time) crashes whenever I wake it up from sleep either immediately or within a few minutes. Hardware test still says it's okay. Thoughts?

    The hardware test isn't that helpful. Does it have any third party ram installed? Failing memory is a frequent cause of panics, and many people fail to test their memory upgrades. Failing logic boards are a much worse one.

    +1. That is exactly what happen to my late 2011 MBP 15". At first I tested all the hardwares and found no issues. But when the MBP started chiming on the start up, it indicated it was the RAM. I forget how many times it chimed. I think there is a code for the number of chimes to the problem.

    It doesn't always chime. Sometimes a chip still works but doesn't work that well. In those cases you have to really test them. Most third party ram is carries a long warranty, so it's one of the cheaper fixes. It's a lot worse if the issue is a failing logic board.
