Is your computer powering-up randomly at strange times? If your computer turns on by itself after shutting it down, it can freak you out a little bit and make you think of hackers. Don’t worry, I am here to help.
No matter whether your device is connected to a budget monitor like the under $200 ones here, or a top-shelf gaming monitor, I will give possible causes for this problem and give ways of fixing it in this guide.
Why does my Computer keep Turning on after I Shut it Down?
It is creepy when you wake up in the morning and discover your computer connected to a brand new Xbox monitor is already turned on and you’re 100% sure that you had put it to sleep.
Many users have experienced this problem. In fact, many did not know that a computer turns on by itself without pressing its power button. The uncontrolled waking has something to do with one of these;
- Power management settings that are currently allowed
- Missing or corrupt drivers
- System failure updates or scheduled windows update
- Your task scheduler
- A BIOS issue
- Stuck-up or hold the power button
- Power surge
- It could be a Virus or other malware
How do I Stop the Computer from Turning Itself On?
When a computer turns on by itself, most users think that this is a hardware problem only to discover that it’s also a software issue or setting.
There are a number of ways to solve this issue but first, make sure to check which devices brought your computer out of sleep mode. Occasionally, some devices such as a keyboard can send a wake-up signal or make your computer turn on by itself.
Run Administrator Command Prompt
To figure out which hardware devices woke your computer from standby mode, make sure to follow these steps;
1. Click the start icon on your windows operating system
2. Next, type cmd into the search box
3. you will see a command prompt or CMD in the windows search result
4. using your mouse, hover over the result command prompt and right-click
5. Click on run as administrator. Double click ok.
1. Powercfg –Devicequery Wake_from_Any
The above command will display hardware devices that are capable of making your device wake up. Powercfg devicequery wake armed-I also use this command to lists all devices that wake up my computer. However, in most scenarios, the operating system naturally ignores start-up prompts from most of the hardware.
2. Powercfg -Devicequery Wake_Armed
This Powercfg Devicequery Warmed cmd command generates a much shorter list compared to Powercfg –Devicequery wake-from-any. The possible devices to be found in this list are;
- the keyboard
- or network adapters
To find your culprit, you can disable these devices one by one until you find the one that is responsible for waking up your computer.
3. Powercfg Lastwake
The Powercfg Lastwake tells you the reason why your computer turns itself on the last time. Windows 10 has a regular maintenance task scheduler that requires waking or turning on the computer from sleep mode.
It helps to keep your computer utilities running as smoothly as possible by proactively installing the system and drivers’ updates or perform scans when idle. On the other hand, monitors, no matter whether they are easy on the eyes like these fine examples here, meant for work as the ones in this post, or the cheapest G Sync ones we also reviewed, are most probably not the source of the problem.
4. Powercfg –Devicedisablewake “device name”
Once you find the device or hardware that is causing your computer to turn itself-on, make sure to disable it using the above command prompt command.
Just in case you had disabled other devices in the process of troubleshooting, you can still enable them using this command power –Deviceenablewake “device name”.
Stop Mouse and Keyboard from Waking your Computer Device to Wake

3. Right-click on the first option and open properties
