Try disconnecting peripherals and accessories from your computer and see if it still turns on during sleep mode. If not, it might be necessary to consult a technician to diagnose and repair any hardware malfunctions.

Sleep mode should ideally keep your computer in a low-power state until you actively wake it up but if you find your computer frequently turning on during sleep mode, it can be quite frustrating. Several reasons may cause this issue, ranging from software settings to hardware malfunctions.

The most common reason for a computer turning on in sleep mode is the “Wake on LAN” feature enabled in the BIOS settings. This feature allows your computer to receive a signal from the network to wake up. To check if this is the case, restart your computer and access the BIOS settings. Look for the “Wake on LAN” or “WoL” option and disable it if enabled.

Another possible cause is a Windows update disrupting power settings or introducing new features. To prevent updates from turning on your computer, go to “Settings,” then “Update & Security,” and navigate to the “Windows Update” section. From there, click on “Change active hours” and specify the hours during which your computer should not restart.

Scheduled tasks or programs can also wake up your computer from sleep mode. To check and modify these tasks, open the Task Scheduler by searching for it in the Start menu. Browse through the created tasks and modify them as needed.

Faulty hardware, such as a malfunctioning power button or a faulty wake-up mechanism, can also be the culprit. To troubleshoot hardware-related issues, disconnect peripherals and accessories from your computer and check if it still turns on during sleep mode. If the problem persists, it is advisable to seek assistance from a technician.

In conclusion, a computer turning on in sleep mode is typically an anomaly and not the intended behavior. By identifying and addressing the potential causes discussed above, you can ensure a more seamless sleep mode experience and save energy in the process.
