With work from home and schooling from home increasing, many have begun to use their computers and laptops for a longer time. Like any electronic appliance, the computer/laptop also needs some rest to cool off. Not only that, even the eyes need some rest from time to time. The best way is to activate the sleep mode on the laptop. You will be able to give some cooling off time to the laptop and also be able to rest your eyes.
The sleep mode feature in the computer or laptop will ensure that the battery power is saved and helps maintain the laptop’s health in the longer run. Much is written about the advantages of the sleep mode in the PC/laptop, yet many have encountered issues in this matter.
Take the case of one common complaint. In Windows 10 & 11, the sleep mode is a handy feature commonly used. However, some have reported that the PC automatically wakes up even when the sleep mode is turned on. While this does not cause any significant problems, it still can be distracting and frustrating if it occurs at regular intervals.
So if such a situation is encountered, what is the best solution?
First and foremost, please be reassured that this issue is not a sign that your laptop is spoilt or there is some major error/system file corruption in the computer. Instead, it is a case of enabling or disabling wake timers in Window 10/11.
For those encountering this issue for the first time, a wake timer refers to a timed event that wakes up the computer from the sleep mode at a specific time. It can be set up in the Task Scheduler box, such as reboots after a windows update. These can supersede all other settings. So if your computer/laptop wakes up automatically from the sleep mode, it means that the ‘allow wake timer option is enabled.
Simply follow the steps detailed below to disable or enable wake timers in Windows 10 /11.
The steps to enable or disable wake timers in Windows 10 /11 are :
1. Go to the control panel in Windows 10 /11, and in the search bar, type the word ‘power.’
2. From the search results, click on the ‘Edit power plan’ option, and from that page, go to the ‘Change Advanced Power Settings’ option.
3. Herein expand the ‘sleep option’ button. There will be an option ‘Allow Wake timers.’ From its drop-down menu, select the option ‘enable’ or ‘Disable’ if your system is battery enabled. If your PC or laptop is not battery enabled, then under the ‘plugged in’ section, you need to select enable or disable accordingly.
Please note that the settings must be changed twice in two different locations, especially if using a laptop. This is because most laptops have two modes, plugged in and on battery. So the settings have to be changed twice. So in just the above-mentioned three easy steps, you can either enable or disable wake timers in Windows 10 /11.
Another important question arises, which is how to find out what exactly is set to wake up the PC? And also which program has woken up the computer?
For the answer, go to the Start Orb option and type CMD. Right-click on the CMD.EXE and select Run as Administrator. Then type powercfg-devicequery wake_armed. This command will show what built-in devices or programs will wake up the system. Unfortunately, there is no button or program to tell exactly what woke up the laptop or computer. But by using the command powercfg -the last wake will logically show what last awoke your computer. However, you need to run it immediately after the PC wakes up. Also, by using the command, powercfg -waketimer, you can get a list of all active wake timers
As understood from the above article, even when the computer or laptop is under sleep mode, it can wake up automatically to complete a task that was preset as per schedule. Case to quote, for example, is the automatic updates. If set for predefined times, it will automatically wake up your PC’s system and install the updates. However, you can turn it off or on based on your requirements.
