Last month I installed a OWC 240GB Mercury Electra 6G SSD on my 13 inch 2012 MBP and have been using it ever since as my primary boot drive. But in the last week or so I have started noticing that when I have my laptop in sleep mode with the lid closed and running off battery power, when its been in such state for over two hours, whenever I open the lid I see the lock screen but the Mac emit the sound they make when you boot up when its been off and the lock screen seems stock in motion until it seems to connect the drive again. At first I thought it was because I had reset the energy preferences to its default settings that enabled the "put hard disk to sleep whenever possible" when before hand I didn't had it enabled due to talks from the drive's manufacturer that said option is unnecessary with a SSD. So I disabled it again but it seems to not have mitigated said behavior and went ahead and reset both the SMC & NVRAM to no avail. As a last ditch effort for a explanation I thought that it might have been a energy saver setting on the firmware of the drive and so I called and spoke with Apple & OWC but neither could give me a reason as to the possible causes of this issue if any. Does anyone have any other ideas or suggestions for me to try out ? Thanks for your time.
