Steps to reproduce:
- Be doing anything
- Close the lid of the computer
- Wait around for a while
- Open the lid of the computer
- Login prompt for last logged in user appears, battery and time MAY update, but trackpad and keyboard are locked up and no response. Computer requires forced-restart.
EDIT: 5a. Possibly, everything is normal, and no lockup/freeze happens.
When the problem occurs, there is no spinning wait thingy or blinking cursor. On the contrary, a spinning wait cursor usually indicates that if I wait for it, the machine will wake up normally, blink the cursor, and let me log in.
EDIT 2a: Software running may vary. No indication of wifi connectivity since the icon may or may not be on, but I may or may not have been connected to wifi at sleep, and may or may not have wifi access at wake--there's no way to tell if the image is actually reporting the state since the image may just be frozen.
EDIT 2b: As best I can tell, the longer I wait to re-activate the machine, the more likely the lockup.

Any ideas on how to diagnose or fix?
