What You'll Learn
Identify what woke your computer up
If your Windows computer is waking up from sleep mode without any apparent reason, there are several steps you can take to find out what is causing it. Here are some tips to help you troubleshoot the issue:
Check the Event Log: The event log records all system events, including the reasons why your computer woke up from sleep mode. To access the event log, go to Control Panel > System and Security > Administrative Tools > Event Viewer. In the Event Viewer, you can find the Power-Troubleshooter option, which will provide information about the wake source, sleep time, and wake time. You can also try filtering by Kernel-Power, although this may not provide as much useful data.
Use the Command Prompt: Open the Command Prompt as an administrator and type "powercfg -lastwake" (or "powercfg -waketimers") to find out what woke up your computer last. You can also use the POWERCFG command on Windows Terminal to control the power states of individual devices and analyze the system for common energy efficiency and battery-life problems.
Check Power Settings: Incorrect power settings can cause your computer to wake up from sleep mode unexpectedly. Go to Control Panel > System and Security > Power Options and click on "Choose what the power buttons do." Ensure that the settings are configured to your preferences and that no options are enabled that could wake up your computer from sleep mode.
Identify Connected Devices: Sometimes, a connected device can be the culprit. To identify this, remove all your USB devices the next time you put your computer to sleep. If it doesn't wake up on its own, start plugging in devices one by one until you find the offending device. Once you've identified it, you can change its power settings to prevent it from waking up your computer in the future.
Disable Wake Timers: If none of the above solutions work, you may need to dig into the wake timers set on your computer. Open the Start menu, search for "Edit Power Plan," and click on "Change Advanced Settings." Head to Sleep > Allow Wake Timers and disable the options for both Battery and Plugged In. Note that this will affect all wake timers, so if you have specific timers you want to keep enabled, this may not be the best solution.

Disable wake timers
If your computer is waking up from sleep mode, there are a few settings you can tweak to fix the problem.
First, you need to determine the problem. You can usually figure out what event caused your computer to wake up most recently with a simple Command Prompt command. Start the Command Prompt by hitting Start, typing CMD and then selecting the "Command Prompt" app. In the Command Prompt window, type powercfg -lastwake and press Enter.
If you don't want any programs waking your computer up automatically, you can disable wake timers entirely. To do so, type Edit power plan in the Start menu and hit Enter. Then, click the "Change Advanced Power Settings" option. Expand the "Sleep" entry, double-click the "Allow Wake Timers" entry below it, and then set the entries below it to "Disabled". If you’re on a laptop, you’ll see two entries—On battery and "Plugged in. Choose the "Disabled" option for both.
There’s also a third option besides enabling or disabling wake timers. This option is called "Important Wake Timers Only" and wakes your PC only for major Windows system events like a scheduled restart of your PC outside active hours following a Windows update. You can try setting your wake timers to "Important Wake Timers Only" and see if it solves your problems. If your PC is still waking up more often than you'd like, you can always come back and set wake timers to "Disabled" instead.
If you're using Windows 10, it is strongly recommended that you fix this setting for all power profiles, not just the one you have chosen to use. Various Windows faculties will use different profiles, improving your chances of not being woken up.
You can also run a PowerShell command to weed out all tasks that can, feasibly, wake your PC. Open an Administrative PowerShell command prompt (Start, type 'Powershell', Ctrl+Shift+Enter) and place this command in the window. Go through all the tasks it lists and remove their permission to wake your computer.

- Adjust or Uninstall Offending Programs: If a specific program, like a cloud backup application, is causing the issue, adjust its settings or uninstall it.
- Check Hardware Devices: If a hardware device is listed as the cause, disconnect all USB devices the next time your computer sleeps. If it doesn't wake up, reconnect the devices one by one to identify the problematic hardware.
- Windows Update: Use Windows Update's built-in tools to schedule updates and reboots during your active hours.
- Wake Timers: Open the Start menu, search for "Edit Power Plan," click on Change Advanced Settings, go to Sleep > Allow Wake Timers, and disable the feature for both battery and plugged-in modes.

Prevent automatic maintenance from waking your computer
If your computer keeps waking up from sleep mode, there are a few settings you can tweak to fix the problem.
Firstly, you need to determine what is causing your computer to wake up. You can usually find out what event caused your computer to wake up most recently with a simple Command Prompt command. Start the Command Prompt by hitting Start, typing CMD and then selecting the "Command Prompt" app. In the Command Prompt window, type powercfg -lastwake and press Enter.
If you don't want any programs waking your computer up automatically, you can disable wake timers entirely. To do so, type Edit power plan in the Start menu and hit Enter. Then, click the "Change Advanced Power Settings" option. Expand the "Sleep" entry, double-click the "Allow Wake Timers" entry below it, and then set the entries below it to "Disabled".
By default, Windows runs automatic maintenance tasks at 2:00 am every night if you're not using your computer. It's also set to wake your PC from sleep to run those tasks. These tasks include things like checking to see if your hard drive needs defragmenting, running system diagnostics, checking for disk volume errors, and more. They are important tasks to have run periodically, but if you'd prefer that Windows not wake your PC to do it, you can turn that setting off. Open the Control Panel, change the View by setting to "Large icons," and select "Security and Maintenance." On the Security and Maintenance page, expand the Maintenance section and click "Change Maintenance Settings." On the Automatic Maintenance page, uncheck the "Allow scheduled maintenance to wake up my computer at the scheduled time" option and click "OK." If you'd rather keep the feature on but at a different time, you can also update the schedule to one that works better for you.
If you are using Windows 10, you can also try the following:
- Open the "Task Scheduler" and go into the tree as follows: Microsoft\Windows\UpdateOrchestrator\Reboot.
- Right-click -> Properties -> Conditions -> Uncheck "Wake the computer to run this task".
- Change registry entry hkey_local_machine\software\Microsoft\Windows NT\CurrentVersion\WinLogon\PowerdownAfterShutdown to 1.
Other general fixes include using Windows Update’s built-in tools to more meticulously schedule updates and reboots, using the Event Viewer to see when your computer turned off and when it woke up, and disabling the "Enabling Windows Update Power Management to automatically wake up the system to install scheduled updates" option.
