You use a computer that is running Microsoft Windows XP with Service Pack 2 (SP2), Microsoft Windows XP Tablet PC Edition 2005, or Microsoft Windows XP Media Center Edition 2005. When you try to put the computer in hibernation, the computer occasionally does not hibernate. When this problem occurs, you receive an error message that is similar to the following:
When you experience this problem, the hibernate feature is not available on the computer until you restart the computer.
Insufficient System Resources Exist to Complete the API.
This problem typically occurs when the computer uses 1 gigabyte (GB) or more of RAM.
Note The Windows XP SP2 features and components are included in Windows XP Tablet PC Edition 2005 and in Windows XP Media Center Edition 2005.
This problem occurs because the Windows kernel power manager cannot obtain the memory resources that are required to prepare the computer to hibernate.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
To prepare the computer to hibernate, the Windows kernel power manager requires a block of contiguous memory. The size of this contiguous memory is proportional to the number of physical memory regions that the computer is using. A computer that uses lots of RAM is likely to use more physical memory regions when the computer prepares to hibernate. Therefore, a larger amount of contiguous memory is required to prepare the computer to hibernate.
Additionally, the number of physical memory regions varies according to the programs, services, and device drivers that the computer uses. Therefore, the hibernate feature occasionally fails.
When the Windows kernel power manager detects that the hibernate feature has failed, the hibernate feature remains disabled until you restart the computer.
