To work around this issue, decrease the RAM to 4 GB or less on a computer that is running Windows XP, Windows Server 2003, Windows Vista, or Windows Server 2008.
Note Sometimes, the
Hibernation tab is unavailable even after you decrease the RAM to 4 GB or less. This issue occurs because PCI memory resources are mapped in the middle of 4 GB physical memory address spaces, and the rest of the RAM is mapped to more than 4 GB of physical memory address space. If the value of the highest physical memory address is larger than 4 GB, Windows determines that the computer has more than 4 GB of memory. Therefore, the
Hibernation tab is disabled. In this scenario, you must add the
/MAXMEM=4096 switch to the Boot.ini file to reduce the highest physical memory to 4 GB.

To work around this issue on a computer that is running Windows Vista, enable hibernation. To do this, run the following command as an administrator:
powercfg /h on
To do this, follow these steps:
- Log on as an administrator.
- Click Start, type cmd in the Start Search text box, right-click cmd.exe, click Run as administrator, and then click Continue.
- At the command prompt, type powercfg –h on, and then press ENTER.
