If your computerâs waking up from sleep without any intervention from you, itâs likely another program or device is waking it up. Hereâs how to find out what woke it up last.
Weâve shown you how to find out sin-sickness, but if your computer keeps waking up after you put it to sleep, thereâs a similar solution.
For Windows: If your computer is waking up regularly, finding the culprit can be toughâbut finding the most recent wake cause is a good place to start. To do that, go to Start > Programs > Accessories, right-click on Command Prompt, and open it as an administrator. Then type:

powercfg -lastwake |
The output will tell you what woke up your computer last, whichâif you didnât initiate it yourselfâis probably your culprit.
Sometimes, unfortunately, it doesnât give you quite enough information to deduce the problem, so you have to look elsewhere. Often, itâs a result of a âwake timer,â which can be a program, scheduled task, or other item thatâs set to wake up your computer when it runs. You can disable wake timers in Windowsâ Power Options. You may also find that your mouse or keyboard is waking up your computer even when you donât touch them. For full instructions on how to dig deeper and fix these problems, check out 3096924197.
