Computer Turns On by Itself YouTube from www.youtube.com Imagine leaving your computer turned off before going to bed, and waking up to find it has turned on by itself. This can be a frustrating experience, especially if you don't know the root cause of this issue. In this article, we will discuss the possible reasons why your computer turns on by itself and how to fix this problem.
What Causes a Computer to Turn On By Itself?
1. Power Settings
One of the most common reasons why a computer turns on by itself is due to its power settings. If the settings are configured to turn on the computer at a specific time, the computer will turn on by itself. This can be intentional, such as setting an alarm, or unintentional, such as an update that changes the settings. To check your power settings, open the "Control Panel" and click "Power Options." From there, click "Change plan settings" and then "Change advanced power settings." Look for the "Power buttons and lid" option and check if the "Power on by keyboard" or "Power on by mouse" options are enabled.
2. Wake-on-LAN
Another reason why a computer turns on by itself is due to Wake-on-LAN (WoL) settings. WoL is a feature that allows a computer to be turned on remotely using a network message. This feature is often used in business environments to remotely manage computers. To check if WoL is enabled, open the "Device Manager" and expand the "Network adapters" section. Right-click on the adapter and select "Properties." From there, click on the "Power Management" tab and uncheck the "Allow this device to wake the computer" option.

Follow the steps mentioned above to access the power settings and disable the "Power on by keyboard" or "Power on by mouse" options. Additionally, you can also disable the "Wake timer" option to prevent the computer from turning on at a specific time.
2. Wake-on-LAN
To fix a computer that turns on by itself due to WoL settings, you need to disable the feature. Follow the steps mentioned above to access the WoL settings and uncheck the "Allow this device to wake the computer" option.

Another reason why a computer turns on by itself is due to its BIOS settings. The BIOS is responsible for controlling the computer's hardware and configuring its settings.
