Win8.1 system can not sleep solution

Win8.1 system users want to restart the hibernation function, you can open the command prompt window, and then enter "ldcfg; powercfg -h on". But at this time the problem comes, 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.
