System setup causes display fake black screen how to solve

In one case, the monitor power-saving management is set to automatically turn off the monitor for a certain amount of time (for example, 15 minutes), and in another case, the system will not be awakened by a black screen due to excessive file fragmentation and file clutter in the system after it is turned into sleep.

Workaround:

① for the first case: right mouse click, property screen saver settings to turn off the monitor, set it to never be able to.

② for the second scenario: Click the Start Program Attachment System tool Disk Defragmenter to defragment the hard disk files. If you have errors on your hard drive, you will need to fix the errors before defragmenting the disks.
