Possible causes for automatic wake-up after sleep in Windows 7

Sleep is a very good function, and sleep is fast and can be immediately restored to the status before going to bed, which is more convenient than normal shutdown and boot. Later, I found that sometimes I will automatically wake up after sleep. After waking up, I stayed on the welcome page. There was no exception prompt orProgramRun. Check the list below to solve this problem. If you encounter a similar problem, you can refer to it.

1. check whether there is a program pop-up window or other prompts after waking up.

2. Whether to enable Network wake-up. If network wake-up is enabled, the system may automatically wake up in some cases.

3. Check the devices that can wake up computers in the Device Manager. You can right-click a device name, choose properties, and choose power management.

If you need to use the mouse or keyboard to wake up normally, set them (or one of them) to wake up the computer.

4. For devices that can wake up a computer, check whether the computer is awakened due to accidental clicking or hitting.

5. check whether there are any scheduled tasks required to wake up the computer. If you do not need it, you can set it on the scheduled task Properties> conditions tab> power supply.

There may be many scheduled tasks. You can first view the event manager, find events that are similar to the wake-up time, and use these records to find related scheduled tasks.
