Question: Problem with waking up from Safe Sleep

My MBP just ran out of juice and went into safe sleep.


I connected the charger and pushed the power switch and walked away.


Suddenly the machine starts beeping and flashing its LED indicator. I look at the monitor and the progress bar for waking up is at the very last step.


I have a video of this, if only "Insert video" actually worked.. Oh, well. If anyone's interested they can download the .mp4 here.


Regards,

Henry.

Answer:
Answer:

Turns out my problem was the Deep Sleep widget I had on my Dashboard.


I removed the widget, went into System PreferencesEnergy saver, and restored defaults on both tabs.


Then I opened a command prompt and set the hibernate mode to 3:

sudo pmset -a hibernatemode 3


That stands for "suspend to disk + RAM" which should be the default on MacBooks.


I rebooted, and now it can let the battery run out, and my MacBook wakes up from hibernation without issue.

I don't know if this will have a bearing to your situation, but my ML install went without hitch but whenever my system went to sleep and was awoken later, it was a bit slow to respond, sometimes virtually locked.


I discovered my problem was related to Sophos Anti Virus.


I don't know if you have this installed but the 'Shield' kept disappearing from the Toolbar when the system awoke.


I removed Sophos and performed a fresh install of Mountain Lion and so far 24 hours later, with the system going to sleep several times, it's awoken with out issue.
