Solve Win7/Win8 can not open hibernation problem

The Win8 sleep feature is very important because it has a quick start feature. The Win7/Win8 sleep function is enabled by default, but some users with tight disk space have turned off the sleep function.

If you want to re-open, you can open the command prompt window, and then enter “powercfg -h on” . At this time, the problem will come, prompting "sleep failure, the error is as follows: The request is not supported" .

This happens because your disk space is not enough to generate a hibernation file (hiberfil.sys) that is as large as physical memory. Assuming you upgraded the memory, the hiberfil.sys file will grow larger as the memory grows. In the case of insufficient disk, the system will turn off the sleep function by default.

Solve [hibernation failure, the error is as follows: The request is not supported] The problem:

1. Clean up the temporary files of the disk, see how long your recycle bin has not been cleaned, not commonly used software Uninstall and install to other drive letters.

2. Set the temporary folder, virtual memory, and documents to other drive letters.

3. Slimming your Win8: delete the system's own application backup, delete the msi temporary decompression directory, zero-byte backup directory, delete Download download backup.

4. The ultimate method: divide the capacity of other drive letters to the system disk through the partition assistant software.

Finally: Open the command prompt window, or run as administrator, then enter “powercfg -h on”, which will enable hibernation again.
