Wake from deep sleep/memory screen

Hi,

After my MBP 13" 2012 is on deep sleep with power supply plugged, when i awake it, i have the screen like there was no more battery and memory was backup to the HD. (not easy to explain, the screen is grey and the desktop is fuzzy, and there are progession white rectangles)

It's not normal as i have the power on. It never happens when only on battery.

I'm in 10.8.2, with 16Go Ram, and a SSD Crucial M4 512Go.

It's seems i'm not the only one, and i'm not sure if it's memory related, or SSD, or OS.

Thanks

MacBook Pro, OS X Mountain Lion (10.8.2)

I have one of the affected drives. Have you tried this procedure from Crucial?

Post your results!

Thanks for your reply.

From what i understand this procedure from Crucial is when the SSD isn't recognize anymore by the OS. It seems it arrives with the firmware 010G. I am still in 000F, and my drive is working very well.

The only problem is when wake up from deep sleep and i have this screen showing up that the memory data is copying back from hard drive to physical memory. I just have to wait 5 seconds and my computer works as normal.

It seems my computer is going to safe sleep when sleeping with AC power.

This is not a issue of your SSD. Apple introduced this "feature" to comply with EU regulations. Take a look at the discussion here. There are a couple of posts (like this) explaining the procedure to avoid this behavior:

Go to Terminal and enter: sudo pmset -a autopoweroff 0

To undo type: sudo pmset -a autopoweroff 1

Hope this helps...
