Sleep mode is a power-saving state that allows a computer to quickly resume full-power operation, usually 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 usually press any key on the keyboard, click the mouse, or press the power button. If this does not work, you may need to delve into the power settings or update your system's drivers.

Troubleshooting a computer that won't wake from sleep mode
If your computer won't wake from sleep mode, there are several troubleshooting steps you can take to resolve the issue. Here are some methods to try:
Basic Checks
Firstly, try performing some basic checks to wake your computer:
- Move your mouse or press any key on your keyboard.
- If that doesn't work, quickly press the power button on your computer.
- If you're using a laptop, try opening the lid and using the embedded keyboard or pointing device.
Check Power Settings
Ensure that your power settings are configured correctly:
- Go to Start > Settings > System > Power & Battery > Screen and Sleep.
- Adjust the settings for how long you want your device to wait before turning off the screen and going to sleep.
- Check that your power buttons are set up correctly: Go to Start > Settings > System > Power & Sleep > Additional power settings > Choose what the power buttons do.
Update Operating System
Ensure that your operating system is up to date. For example, if you're using Windows Vista, update to Service Pack 1 or later.
Check Keyboard Settings
Check that your keyboard is configured to wake the computer when you press a key:
- Go to the Keyboard control panel.
- Click the Hardware tab, then click Properties.
- Click the Change Settings button (this may require Administrator access).
- Click the Power Management tab, and verify that "Allow this device to wake the computer" is enabled.
Update BIOS Settings
If the above steps don't work, try updating your BIOS settings:
- Access the BIOS setup screen by pressing and holding the F2 key while powering on your device.
- Once in the BIOS setup screen, refer to instructions for restoring BIOS settings to default.
- Alternatively, you can enable USB Wake Support in the BIOS settings.
Run Windows Power Troubleshooter
You can use the built-in Windows Power Troubleshooter to adjust your power settings:
- Open the Control Panel and type "Troubleshooting" in the search field.
- Click on Troubleshooting, then under System and Security, click on Improve Power Usage.
- Run the Power troubleshooting tool, and after completion, test if the issue is resolved.
If none of these methods work, you may have encountered a system problem. Refer to your computer's documentation or contact the manufacturer for further support.

Using the sleep keyboard shortcut
Keyboard shortcuts are a convenient way to put your computer to sleep. They save you the tedious process of scrolling through menus and allow for easy power management.
If your keyboard has a dedicated sleep key, pressing it will put your computer to sleep. If not, you can use the "Alt + F4" shortcut to bring up a shutdown dialogue with a sleep option. This shortcut is especially useful when you don't have a mouse.
For Windows 10, there are multiple ways to put your computer to sleep. You can use the start menu, the power user menu (accessed by right-clicking the start button), or a designated sleep button on your keyboard, if it has one. You can also configure the power button to activate sleep mode, which can be adjusted in the power options within the control panel.
Additionally, you can create a desktop shortcut for sleep mode. This can be done by opening the Power User Menu with "Win + X" and quickly accessing power options.
However, keep in mind that some keyboards may not support sleep mode, and you might need to update your operating system or adjust settings to enable this feature.

Changing power settings
If you are using a Windows computer, you can change the power settings by going to Start > Settings > System > Power & Battery > Screen and Sleep. Here, you can select how long you want your device to wait before turning the screen off and going to sleep. You can also select the power mode to optimise your computer for performance or power efficiency.
If you are using a desktop or tablet, you can select "Choose what the power buttons do". Next to "When I press the power button", select "Sleep", and then select "Save changes". If you are using a laptop, select "Choose what closing the lid does". Next to "When I close the lid", select "Sleep", and then select "Save changes".
You can also access advanced power settings by double-clicking on your chosen power plan in the Control Panel. This will allow you to fine-tune various aspects of your power usage, such as adjusting the sleep timer or changing what closing the laptop lid does.
Additionally, you can change the settings for individual devices to allow them to wake your computer from sleep mode. To do this, navigate to the Device Manager, find your device, and go to its properties. Under the "Power Management" tab, check the box next to "Allow this device to wake the computer". This setting ensures that a simple mouse movement or keypress can bring your computer out of sleep mode.
It is important to note that some BIOS (Basic Input/Output System) settings can impact how your computer wakes from sleep. If you are experiencing issues, you can try accessing the BIOS setup during startup (usually by pressing a key like F2 or DEL) and adjusting the power management settings.

Using the BIOS settings
The BIOS (Basic Input/Output System) settings can significantly impact how your computer wakes from sleep. Some BIOS configurations may prevent proper wake-up or cause the computer to enter sleep mode prematurely.
To access the BIOS setup, you usually need to press a specific key during startup, such as F2 or DEL. This allows you to check and adjust power management settings and sleep mode settings, potentially resolving wake-up issues.
In the BIOS settings, you can enable the "Allow this device to wake the computer" option. This setting is available for keyboards and mice, and it ensures that your device can wake up your computer from sleep mode.
Additionally, you can find network wake-up options in the BIOS. You can uncheck the "Allow This Device to Wake the Computer" option and instead select "Only Allow a Magic Packet to Wake the Computer." A magic packet is useful if you use Wake-On-LAN to access sleeping computers remotely.
Keep in mind that wireless devices, such as Bluetooth keyboards and mice, may not always wake the computer due to connectivity issues or power-saving features. Laptop manufacturers often do not allow Bluetooth devices to wake the computer from sleep mode to conserve power.
By adjusting the BIOS settings, you can tailor your computer's sleep and wake behaviour to your preferences and ensure a smooth wake-up process.
