Sleep on E6520 only working once

Hi,

 

first off thanks to you guys for making it so easy getting OS X to run on Latitudes. 10.8.2 runs like a charm on my E6520 with only minor quirks, and for me it's totally usable.

 

I do have one problem with sleep however. If i boot up OS X and put it to sleep, it works and wakes up again flawlessly. However, if I put it into sleep mode after that, it won't enter it. The system freezes, the screen goes dark, but the computer keeps running.

 

Has anyone solved a similar issue or could drop me a hint how where start looking for what's going wrong?

 

Edit: I'm using hibernatemode 3, suspend to disk. Mode 1 does not work at all.

After 1st boot, could you try the following?

1) from a Terminal window, type the 'pmset -g' command (or 'sudo pmset -g') to get the Power Management settings

2) put your laptop to sleep, then wake it

3) redo a 'pmset -g' again to compare
