Sleep mode is a power-saving state that allows a computer to quickly resume full-power operation within a few seconds when you want to start working again. However, waking a computer from sleep mode can sometimes be tricky, especially in Windows 10 or 11. To wake a computer from sleep mode, you can try pressing any key on the keyboard, clicking the mouse, or pressing the power button. If you are using a Bluetooth device, you may need to try an alternative method as this may not be effective in waking the computer. If you are still unable to wake the computer from sleep mode, you may need to try updating your system's drivers or delving into the power settings.

What You'll Learn
Troubleshooting problems with your keyboard or mouse
Unplug and Replug the Device
Try unplugging the problematic device and then plugging it back in. If that doesn't work, try plugging it into a different USB port. If you use a USB hub, make sure it has power, and try removing the hub and plugging the device directly into a USB port on your PC.
Check for Updates and Install Drivers
Make sure your device drivers are up to date. Open Device Manager on your computer, find your keyboard or mouse in the list of devices, right-click on it, and select 'Update driver'. Choose the option to search automatically for drivers. Check for other updates by selecting 'Start', 'Settings', 'Update & Security', and 'Windows Update'.
Check Wireless Connections
If you're using a wireless keyboard or mouse, make sure the transceiver (the small USB dongle that comes with the device) is plugged in. Try changing the batteries in your devices, as low battery power can cause connectivity issues. If your device is Bluetooth, make sure Bluetooth is on and select 'Add Bluetooth or other device' in your settings. Choose your device from the list and follow any instructions.
Check for Physical Damage
Inspect your keyboard or mouse for any physical damage, such as frayed or torn wiring, which might require you to replace the device.
Check for Specific Key Issues
If a specific key is not working or sticks, turn off the computer and use a can of compressed air to clean around the problem key. Then, retest the keyboard. If the problem only occurs in a specific program, you must troubleshoot that program.
Check Mouse Functionality
If you're having trouble with your mouse, make sure you're using it on a smooth, flat surface that is not shiny or reflective. A mouse pad can help create a consistent work surface.

Using the power button to wake your computer
If your computer is in sleep mode, you can wake it up by moving the mouse, pressing any key on the keyboard, or pressing the power button. If this doesn't work, it may be because your computer does not support Advanced Configuration and Power Interface (ACPI). In this case, you will need to press the power button to wake the computer.
If you are using a desktop or tablet, you can change the power settings so that pressing the power button will put your device to sleep. First, select Start, then Settings > System > Power & Sleep > Additional Power Settings. Next, select 'Choose what the power buttons do'. Then, select 'Sleep' next to 'When I press the power button' and hit 'Save changes'.
If you are using a laptop, you can change the power settings so that closing the lid will put your device to sleep. First, select Start, then Settings > System > Power & Sleep > Additional Power Settings. Next, select 'Choose what closing the lid does'. Then, select 'Sleep' next to 'When I close the lid' and hit 'Save changes'.
If you are unable to wake your computer from sleep mode by pressing the power button, you may need to troubleshoot the problem. For example, if you are using a Microsoft mouse or keyboard, you may need to update your operating system to Windows Vista Service Pack 1 or later. Alternatively, you may need to change your BIOS settings.

Changing power and sleep settings
Understanding Sleep and Power Settings:
Sleep mode is a low-power state that your computer enters when not in use. It saves your current state, allowing your computer to quickly resume where you left off. However, if your computer is using battery power, it will shut down after extended periods to prevent battery drain.
Adjusting Sleep Timer and Power Plan:
You can modify the sleep timer to control how long your device waits before entering sleep mode. On Windows, go to Start > Settings > System > Power & Battery > Screen and Sleep. Here, you can set the desired duration for your device to wait before turning off the screen and entering sleep mode.
Additionally, you can create a custom power plan through Control Panel > Power Options. This allows you to save unique settings profiles for different scenarios, such as maximising battery life or ensuring high performance.
Enabling Keyboard and Mouse Wake-Up:
You can set your computer to wake up from sleep mode with a simple mouse movement or keypress. Go to Device Manager, find your device, and navigate to its properties. Under the 'Power Management' tab, check the box next to 'Allow this device to wake the computer'.
Advanced Power Settings:
For more control, access the advanced power settings. On Windows, go to Power Options and click on 'Change advanced power settings'. Here, you can fine-tune specific aspects, such as disabling sleep mode when the laptop lid is closed or adjusting the hard drive sleep timer.
BIOS Settings:
The BIOS (Basic Input/Output System) settings can impact how your computer wakes from sleep. Access the BIOS setup during startup (usually by pressing F2 or Delete). Here, you can adjust power management settings and sleep mode configurations to resolve any wake-up issues.
By following these steps, you can effectively change the power and sleep settings to ensure your computer wakes up from sleep mode as desired.

Using Safe Mode to restore corrupted files
If you're experiencing issues with corrupted files, you can use the Deployment Image Servicing and Management (DISM) tool and the System File Checker (SFC) tool to scan your system files and restore any corrupted or missing files. Here's how you can use Safe Mode to restore corrupted files:
- Run the DISM tool: Open an elevated Command Prompt with administrative privileges. Type "cmd" in the Search box, right-click on Command Prompt, and select "Run as administrator." Then, in the Command Prompt window, type the following command and press Enter: "DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess". Replace the "C:\RepairSource\Windows" placeholder with the location of your repair source. This command will go online, fetch fresh copies of files, and use them to repair corrupted Windows files.
- Run the SFC tool: After running DISM, you can use the SFC tool to scan and replace corrupted system files. Open Command Prompt or PowerShell as administrator and run "sfc /scannow". This command will scan all protected system files and replace corrupted files with cached copies. If the SFC command doesn't repair any files, it will at least confirm that no system files are corrupted, and you can continue troubleshooting.
- Review the log file: After running SFC, review the log file to determine which system file was corrupted and couldn't be repaired. You can find the log file at "C:\Windows\Logs\CBS\CBS.log".
- Replace the corrupted file: Once you've identified the corrupted file, you can manually replace it with a known good copy. Grant administrators full access to the corrupted file and then replace it with a working copy from another computer running the same Windows version. Ensure you perform a System File Checker process on the source computer to confirm the file is good.
If the above steps don't work, you may need to consider performing a system reset or reinstalling Windows. Always make sure to back up your important data before attempting any significant changes to your system.
