Symptoms

When I put my PC into sleep mode, it automatically wakes up at certain times. What can I do about it?

Resolution

Disable timer

PCs don't know any sleep disorders. If, however, the computer wakes up unexpectedly regularly at night (or even during the day) at certain times, you should check the power saving modes. May be the PC is activated by timed action of the system or an application. These include, for example, scheduled backups. How to proceed:
