My laptop freezes when it automatically goes to sleep (or hibernate) due to Control Panel's Power Options settings. I can not get the laptop to wakeup by pressing any keys including
Delete. Briefly pressing the power button does nothing. I have to hold the power button down for 4 seconds to force the laptop to power off. When it boots up, Windows complains about the laptop not being shutdown properly.
The laptop freezes when I manually put it to sleep (or hibernate) even when automatic sleep (and hibernate) is disabled in Power Options.
Manually sleeping (or hibernating) freezes the laptop even if the laptop is not docked and running on a battery. The only thing connected to the laptop when undocked is my wireless (non-Bluetooth) mouse.
Manual sleep (or hibernate) works 1 time and the second time will freeze the laptop. After a reboot, I can repeat the process (i.e. the first time works and the second time freezes).
Edit 2014/07/15: I replaced the SSD with the original HDD. When I manually put the laptop to sleep and wake it back up, the laptop will freeze a minute or two later. The screen is on and I can see the desktop but nothing responds. I don't even get a chance to put it to sleep the second time.
Docking and undocking the laptop has no effect on the laptop if the Power Options are not set to put the laptop to sleep if the lid is closed.
There are 3 phases to sleep. The first phase lasts a few seconds and flashes the disk light several times with many flashes being very bright. The second phase lasts a few seconds and doesn't flash the disk light at all. The third phase lasts a lot of seconds and keeps the disk light on the entire time but not very bright. The laptop always freezes during the first or second phase… I can't tell which.
I can start and exit Process Explorer several times without freezing the laptop. See this question for more details. If I put the laptop to sleep and wake it up, then exiting Process Explorer will freeze the laptop. It seems the laptop/OS gets into a state after sleeping that anything can cause it to freeze.
I thought about booting into Safe Mode and try sleeping from there. Unfortunately, I didn't see a Start menu option to sleep or hibernate while in Safe Mode.
I tried several other things and put them as answers so that others can upvote them and we can see what generally works.
