This error is caused by the hibernation file size being is too small for the current memory requirements of the computer. To fix this problem, increase the size of the hibernation file by following these steps:

  1. Click the Start button.
  2. In the search box, type command prompt.
  3. In the list of results, right-click Command Prompt, and then click Run as administrator.
  4. In the Command Prompt window type:

powercfg /hibernate /size <size%>

where <size%> equals the size of the hibernation file in percentage of total physical memory.

The default size is 75% and can be increased to 100% with:

powercfg /hibernate /size 100

    After installing Sp1 KB976932 and KB2488113 I am now getting the same INTERNAL-POWER-ERROR with stop code A0 ONLY when entering sleep mode.

    Prior to the installation of the above updates I was only getting a different BSOD but only when resuming sleep mode.

    And yes I did increase the size of the hibernate file, though it is unrelated to the sleep function.

    This is a really dumb issue that should not exist.

    Why is it that Microsoft has time to add unsigned drivers that windows won't load to Windows Update, yet they set hibernate not to work if you have a lot of things open (when you need hibernate the most).

    I ignore a lot of issues with Microsoft products because of the complexity involved.  I know windows is far too complex for one team to handle alone, and this inevitably causes problems...but this is the kind of thing that there is no excuse for.

    This does not work to correct the problem. My system was defaulted to 100% before I did anything, I cannot get Windows to make the hiberfil.sys any larger, I have deleted and recreated the file, and every time I try to hibernate the laptop it BSOD's.
