Windows 7 RC Hibernation

Monday, 29 June, 2009

Just a brief update about my install of the Windows 7 RC. Everything has worked very well on may Sony Vaio TX3XP; the RC drivers did their job, although a couple of device specific hardware failed. Either the XP or Vista drivers from Sony worked. However I couldn’t get hibernation to work, something I use a lot on a laptop. I initially thought it might be the graphics card drivers and I couldn’t find any on the Intel site for my Media Graphics Accelerator 950 chipset. A quick Google however and the drivers can be found here. That didn’t solve the problem though. Typing the following commands at the command prompt gives further info:

powercfg /a
powercfg /hibernate on

The first tells you about supported sleep states and the second tries to turn hibernation on. This didn’t work and I got an error stating “an internal system component has disabled hibernation.” Not helpful. A bit more digging shows a similar problem with Server 2003 in relation to virtualised servers; hibernation simply isn’t supported. Which leads me to believe that if you install Windows 7 into a virtual disk (as I had done) then hibernation will be disabled.
