Windows Vista Hibernate Mystery Explained

None other than Jim Allchin, the soon to retire Co-President of the Platform and Services Division at Microsoft, explains the new power management on the Windows Vista Team Blog.

He explains the rationale behind the Sleep and the new Hybrid sleep options.

This had been a mystery for me when I couldn't find the Hibernate option in Windows Vista. Eventually I found the answer in Windows Help and Support. The separate Hibernate option in the shutdown menu is missing by design when Hybrid sleep is enabled. Windows Help explains the difference between Sleep and Hybrid sleep. Hybrid sleep is a combination of Sleep and Hibernate: when your computer goes into hybrid sleep the contents of the RAM is dumped to disk but the RAM remains powered, so your computer is quickly available for use when you return. When you cut off the power to the computer or it looses power, everything is safely on disk and hybrid sleep is indistinguishable from hibernate.

The default Turn off option through the power button in the Start menu is Sleep for laptop computers. For desktop computers it is Hybrid sleep.

Check out Jim's post for the full story.

When I press sleep mode on my desktop PC it works fine and goes to sleep but as soon as I touch a keyboard button it wakes up, WHY? Is it meant to do that?

...also, a known issue is loosing ones sound card when Vista comes out of Hibernation.

Only way to fix is reboot.

So much for speed.

My laptop uses Vista and if I select Sleep or Hibernate, the laptop wakes up after several hours, does anyone know how to set it to stay in hibernate or sleep? This happens even if I close the lid, having set the options to sleep or hibernate when shut.

@Mike Creed: It's probably trying to refresh a network or something. You could try disabling any networking before hibernating.

@Mike Creed: I think it is "Wake on LAN" function.. do you have connected network cable/enabled WLAN? try disabling option "wake on LAN" in bios setup.

Disabling of wake on LAN in bios works for hibernation only. For sleep mode you have to disable "wol" also for for the network driver within Vista.

Here's a quick and easy FIX!!!!!!

1. Click Start, type command in the Start Search box, right-click Command Prompt in the Programs list, and then click Run as administrator.

If you are prompted for an administrator password or confirmation, type your password or click Continue.

2. At the command prompt, type  powercfg /hibernate on.                                     ( I can't remember if it is with/without the space)

ENJOY!!!!!!!!!!!!
