Windows 7 Prompts the following error: Internal_power_error (a0) The Power Policy manager experienced a fatal error

My computer has failed, prompting the following error: "Internal_power_error (a0) The Power Policy manager experienced a fatal error." (The energy policy manager has a fatal error.) What should I do?

This error is due to the size of the hibernation file that is far less than the computer's current memory requirements. To fix this problem, follow these steps to increase the size of the hibernation file:
1. Click the Start button.
2. In the search box, type a command prompt or CMD.
3. In the list of results, right-click Command Prompt (or cmd), and then click Run as Administrator.

4. In the Command Prompt window, type:
Powercfg/hibernate/size <size%>
Where <size%> refers to the percentage size of the hibernation file in total physical memory.
The default size is 75%, but can be increased to 100% with the following command:
Powercfg/hibernate/size 100
