Question : Problem: Dark Screen after Macbook Pro wakes up from sleep mode

Hi,

I have the following problem - very often (but not always haven't found out when, but it is annoyingly often) my Screen on my Macbook Pro stays just dark when I open the lid to wake it up from sleep mode.

Now I can use the keyboard and it even is working (tested it with a musical software keyboard that was the front application) so it seem like the system is running and working it is just the display that stays dark.

One Solution is of course to press the Power-On-Button for 5 Seconds and Restart the Mac.

Another solution is to hook it to an external monitor (in my office I have an external monitor which is the primary one, when attached) and then most of the times also the Macbook Pro Monitor starts to work - if not, then I have to synchronise both monitors (that always works).

Both solutions are very unsatisfying ... and restarting when you are away from office is a real pain.

Have found several hints on some forums (so it is a known problem) but no real help so far.

Anyone here who had that problem and soled it for good?

Thanks

Patrick

Answer : Problem: Dark Screen after Macbook Pro wakes up from sleep mode

Ok - since I have turned off Safe Sleep, this problem hasn't occurred.

Here is how to do it:

I entered this command at the terminal to change the safesleep mode to 0, and I haven't had the same problem so far....

This command allows you to see what mode you are in...

Code:
pmset -g | grep hibernatemode

This command changes it to NO SafeSleep

Code:
sudo pmset -a hibernatemode 0
