What should I do if the win8.1 quick start option suddenly disappears?

The quick start function provided by win8 is a hybrid sleep mode. When the Windows system is shut down, the system information is saved to a file on the hard disk to realize the next quick start. When you start your computer again, Windows uses the system information file to recover your computer instead of rebooting the system, but some users find that there is no quick start project at the power option, and the quick start disappears.
