What You'll Learn
Troubleshooting a laptop that won't wake from sleep mode
If your laptop won't wake from sleep mode, there are several troubleshooting steps you can try. Firstly, check if your laptop has automatically transitioned into hibernation mode after being in sleep mode for an extended period. In hibernation mode, you can only wake your device by pressing the power button.
If your laptop is plugged into an external power source and not running on battery, you can change the Power settings in Windows to prevent it from going into Sleep mode when plugged in. Additionally, you can try to customise your Microsoft or laptop's proprietary Bluetooth stack to allow waking the laptop from sleep mode using a Bluetooth device.
If you are using a Microsoft input device, you may not be able to wake your laptop from sleep mode. In this case, you can try pressing the power button or opening the lid and using the embedded keyboard, an external non-Bluetooth device, or a pointing device.
For some laptops, you may need to access the BIOS setup screen to modify the settings and resolve the issue. To do this, hold the F2 key until the BIOS setup screen appears, then release it. For older laptop models, you may need to press and hold the Del key during startup to access the BIOS configuration screen.
If none of these solutions work, refer to the documentation that came with your laptop or contact the manufacturer for further assistance.

Using the power button to wake a laptop
Waking up a laptop from sleep can be done in several ways, and the power button is one of the most straightforward methods. This method is especially useful when you cannot open the lid of your laptop, such as when it is in a docking station or has other laptops stacked on top of it.
To wake a laptop from sleep using the power button, simply press the power button once. This action should trigger the laptop to wake up and resume normal operation. If pressing the power button does not work, you may need to press and hold the power button for a few seconds before releasing it. This longer press-and-hold action can act as a forced restart, potentially waking up the laptop.
It is worth noting that some laptops may not allow you to wake them from sleep mode using a Bluetooth device due to power consumption requirements. Keeping the Bluetooth radio activated can consume a significant amount of power, so it is recommended to use the power button or other non-Bluetooth methods to wake your laptop.
If you want to customize your laptop's sleep settings, you can usually do so by accessing the power settings. On Windows, for example, go to Settings > System > Power & Sleep, where you can adjust sleep settings, screen settings, and power mode. Here, you can also select "Choose what closing the lid does" and then "Sleep" under the "When I close the lid" option to make your laptop go to sleep when you close the lid.
Additionally, if you want to wake your laptop from sleep using a specific keyboard key or a mouse click, you may be able to enable this in the power settings. Look for options like "Allow this device to wake the computer" or "USB Wake Support." However, keep in mind that not all laptops may have these customization options available, and the power button is often the most reliable method to wake a laptop from sleep.

Changing power settings to prevent sleep mode
If you want to change the power settings on your laptop to prevent it from going into sleep mode, there are a few things you can do. Firstly, you can adjust the power and sleep settings in Windows. Go to Settings > System > Power & Sleep and select how long you want your device to wait before going to sleep when it's not in use. You can also select 'Additional power settings' to explore more power-saving options and change how your device uses power.
If you want to prevent your laptop from going to sleep when it's plugged in, you can change the power settings in Windows. Go to Control Panel > System and Security > Power Options and select 'Change what the power buttons do'. Then, select 'Change settings that are currently unavailable'. For a laptop, expand the list for 'When I close the lid' in the 'Plugged in' column and select an option other than 'Sleep'.
You can also enable the ''Hibernate' option, which uses less power than sleep mode and is useful when you know you won't be using your laptop for an extended period. To enable hibernation, go to Control Panel > System and Security > Power Options and select 'Change what the power buttons do'. Then, select 'Change settings that are currently unavailable' and choose the 'Hibernate' option in the Shutdown settings section.
Additionally, you can change the power plan on your laptop. Go to Settings > System > Power & Battery and use the drop-down menu under Power Mode to change to the desired power mode. You can also update your laptop's BIOS to the latest version, which can impact power settings.
Keep in mind that the specific steps to change power settings may vary depending on your laptop's make and model, as well as the operating system you're using. Always refer to the manufacturer's documentation or website for detailed instructions specific to your device.

Using a keyboard to wake a laptop
If your laptop is in sleep mode, you can wake it up by pressing any key on your keyboard. If this doesn't work, you may need to press the power button to wake it up.
If you're having issues waking your laptop from sleep mode with your keyboard, there are a few things you can try. Firstly, check your power settings. Go to Start > Settings > System > Power & sleep > Additional power settings. From here, select 'Choose what the power button does', and then 'Change settings that are currently unavailable'. Under 'Shutdown settings', select the 'Hibernate' checkbox (if available), and then 'Save changes'.
You can also try disabling hybrid sleep in the sleep menu and setting hybrid after to 'never'. Then, go to your USB settings and disable USB selective suspend. You may need to restart your laptop for these changes to take effect.
Another solution is to go to your device manager and open the keyboards menu. Right-click on one of the options and go to power management. Make sure the box that says 'Allow this device to wake the computer' is checked, and then click 'OK' to apply. You will need to repeat this process for each of your keyboard devices.
If you're using a Bluetooth keyboard, you may need to customise your Microsoft Bluetooth stack or your laptop's proprietary Bluetooth stack to allow wake functionality.

Using a mouse to wake a laptop
Waking up a laptop from sleep mode can be done in several ways. The most common method is to press the power button on the laptop or lift the laptop lid. However, if you want to use your mouse to wake up your laptop from sleep mode, there are a few things you need to do to enable this feature.
Firstly, check if your mouse hardware supports the wake-up feature. To do this, open the Device Manager by searching for it in the start menu. Expand the "Mice and other pointing devices" section, right-click on your mouse, and select "Properties."
If you can see the "Power Management" tab in the properties window, it means your mouse supports the wake-up feature. Simply select the checkbox that says "Allow this device to wake the computer," click "Ok," and you're done. From now on, you can wake your laptop from sleep by moving your mouse or clicking a button.
However, if you don't see the "Power Management" tab, it could mean one of two things: your mouse driver needs to be reinstalled, or your mouse simply doesn't support the feature. If you want to confirm whether it's the latter, try reinstalling the mouse driver and check again.
It's worth noting that some laptops may not allow you to wake them from sleep mode using a Bluetooth device due to power consumption requirements. If you're having trouble waking your laptop with a Bluetooth mouse, you may need to connect a non-Bluetooth mouse or use the embedded keyboard or power button.
