When the PC has idle time, it goes to sleep after a while and then wakes up when you press the keyboard or move the mouse. However, if your computer either won’t go to sleep on its own or shuts down after manually hibernating, this post will help you fix the problem. One user reported that his computer would automatically wake up from sleep after a while, would not turn on when the USB device woke up, and worse, the power button would not wake the computer from sleep. He had to forcibly turn off the computer and then turn it back on. Sometimes the computer won’t sleep at all.
PC either won’t go to sleep on its own or shuts down after manually going to sleep
If your Windows 11/10 PC won’t go to sleep on its own or shuts down after manually hibernating, here are a few tips to help you resolve the issue:
- Check the external USB devices connected to the PC.
- Check Scheduled Tasks
- Run command powercfg -requests
- Check power plan (laptops only)
- Reset meal plan settings
You will need administrator rights and a good understanding of how power plans work on your PC.
1]Check the external USB devices connected to the PC.
If you have USB devices other than keyboard and mouse, you need to check them all. Disable them and check the behavior changes.
From time to time, USB devices continue to perform activities in the background that wake up the PC. For example, if you have a Bluetooth USB adapter connected to a game controller, both may try to connect and keep waking up the computer. You can try changing the USB port or setting a timeout for such devices so that they don’t try to connect every few minutes.
One user reported that connecting USB-C to USB-2 through the USB 3 port on the back of the motherboard causes confusion throughout the system. So if you have a similar situation, turn them off and check.
2]Check Scheduled Tasks
Do you have a scheduled task that is running in the background that might also wake up your computer? You may never have created it, but your backup program may have scheduled a wake-up backup of your PC.
- Open Run hint using Win + R
- Enter taskschd.msc and click Enter open Task Scheduler .
- Check the trigger column and look at the time for each task.
- If you notice something that is out of place or coincides with the time you encountered the error, disable the task and check for the problem.
3]Run command powercfg -requests
PowerCFG is a command line tool in Windows that can diagnose power management issues. It works great in a situation where the user is not sure why the computer is awake, or why the screen is not turning on, etc.
- Right click startand click on Windows Terminal (Admin) or Command Prompt (admin)
- Once it opens, run powercfg -requests and wait for the result.
- The command will list application and driver power requests.
- Write down the name of the program and see if you can stop the process from running in the background.
Note. The power requests list lists applications that prevent the computer from automatically turning off the display or entering low-power sleep mode.
4]Check Power Plan on Laptops
Laptops have strict power plans that keep the battery running longer than usual. However, many users always keep their laptops connected to a power source. Some users also change the power plan to “Maximum Performance”, which keeps the PC awake.
- Open Windows settings using Win + I
- Switch to Sysbtem > power & battery
- Click the dropdown next to power modeand switch it to balanced or maximum power efficiency.
These modes ensure that the laptop display does not stay on all the time and goes to sleep if it has not been used for some time.
4]Reset Power Plan Settings
If nothing else works and no background apps or devices are causing the problem, your last option is to reset your power plan settings. The best way to do this is with the powercfg command.
- Open Windows Terminal with administrator permission
- Type and run powercfg –restoredefaultschemes
- Let the process complete and all your power plans will revert to the defaults that Windows suggests.
This will change the laptop’s default power plan and even the configurations that Windows allows the end user to control. You may have changed some settings that caused the problem and a reset will fix it.
While it’s annoying when the computer either won’t go to sleep on its own or shuts down after manually hibernating, I hope this post was easy to follow and that you were able to fix the problem for good.
What is the best power plan for a laptop?
It depends on how you want to use the laptop. If you need consistent performance and keep your laptop connected to the network at all times, you can use high performance mode. However, use Power Saver while traveling if you want your battery to last longer.
Does power saving mode affect performance?
Yes it is. Processor speed slows down in power saving mode, which affects overall performance. Do not play games in this mode because the GPU speed will also be limited.
How can I tune my computer for the best performance?
When it comes to the power plan, you need to go for Ultra performance, but there are options. You must make sure you have enough space. A gaming PC needs adequate cooling. There should be enough memory to run resource-intensive applications and games.
Where is Power Management in Device Manager?
Some devices listed in Windows Device Manager have a Power Management tab under their properties. You can allow the computer to turn off this device to save power and allow the device to wake up the computer. Features like Wake On Lan only work when they are allowed to wake up the device.
