Cannot activate hibernate because of PAE on Win XP 64 bit

Question

I'm using Windows XP 64 bit SP2. I'd like to use the hibernate feature. I'm used to activate it under "Power Options". But my current installation doesn't show me the "Hibernate" tab.

I tired to activate is using command line:

powercfg -H on

It gives me an error that hibernate cannot be activated because the system is in PAE mode. This is some kind irritating because this article says that 64 bit windows does not support PAE.

Why am I not able to activate hibernate? Andy why do I get such an irritating error message?

PS: perhaps important informations: My computer runs on 12 GB ram.

Edit 1: My hard drive has 500GB free space.

Answer 1

You cannot put a computer that is running Windows XP, Windows Server 2003, Windows Vista, or Windows Server 2008 into hibernation. Additionally, the Hibernate tab in the Power Options Properties dialog box is unavailable.

Notes This issue occurs if your computer has more than 4 gigabytes (GB) of random access memory (RAM). This issue occurs in both 32-bit and 64-bit versions of Windows.
