What You'll Learn
Check if your BIOS supports USB wake-up
To check if your BIOS supports USB wake-up, you can try the following methods:
Check BIOS Settings
Firstly, you need to access your BIOS settings. To do this, power on your laptop and immediately press the 'Delete' key during boot-up. This should allow you to access the BIOS settings.
Once you are in the BIOS settings, navigate to the "USB Wake Support" option. This option may be under the "`Advanced Power settings` in the BIOS Setup". If you are unable to find the "USB Wake Support" option, try searching for something similar, such as "USB Wake Support (S3)".
If you locate the "USB Wake Support" option, ensure that it is enabled. If it is disabled, enable it, save any changes, and exit the BIOS setup.
Check Device Manager
If you cannot find the "USB Wake Support" option in the BIOS settings, you can try checking the Device Manager. To do this, open the Device Manager and expand the list under "USB". Double-click on a "USB Root Hub" and click on its "Power Management" tab.
Check if there is an option to "Allow this device to wake the computer". If this option is greyed out and cannot be checked, you may need to enable USB Wake Support in the BIOS settings as described above.
Check Compatibility
Another step is to check the compatibility of your laptop model and BIOS version with USB wake-up functionality. Some older laptop models or BIOS versions may not support Wake-on-LAN (WoL) or USB wake-up. Check the documentation, FAQs, and support forums for your specific laptop model to see if USB wake-up is supported.
Try Different USB Ports
If your laptop supports USB wake-up, try using different USB ports on your laptop. Some laptops may have specific ports that support wake-up functionality, such as the system's Smart Power On Connector port.
By following these steps, you can determine if your BIOS supports USB wake-up and configure the necessary settings to enable this functionality on your laptop.

Change power settings to prevent sleep mode
To prevent your laptop from going into sleep mode, you can change its power settings. Here's a step-by-step guide on how to do this:
Step 1: Access Power Options
- Go to the Start menu.
- Select "Settings".
- Choose "System".
- Click on "Power & Sleep" or "Power Options".
Step 2: Adjust Sleep Settings
- Under "Power & Sleep" settings, select "Additional power settings".
- Choose "Choose what the power buttons do".
- Select "Change settings that are currently unavailable".
- Adjust the sleep settings according to your preferences.
- You can set the time duration for your laptop to wait before entering sleep mode when it's running on battery or plugged in.
- Select "Save changes" to apply the new settings.
Step 3: Enable Hibernate (Optional)
- In the "Power Options" or "Power & Sleep" settings, select "Choose what the power buttons do".
- Choose "Change settings that are currently unavailable".
- Under "Shutdown settings", select the "Hibernate" checkbox if it's available.
- Click on "Save changes".
Step 4: Change Lid Settings
- In the "Power Options" or "Power & Sleep" settings, select "Choose what closing the lid does".
- Set the laptop to do "Nothing" when the lid is closed.
- This will prevent the laptop from entering sleep mode when you close the lid.
By following these steps, you can customise your laptop's power settings and prevent it from automatically entering sleep mode. You can also enable hibernate mode, which saves power and is useful when you won't be using your laptop for an extended period.

Use an external mouse to wake your laptop
If you want to wake up your laptop from sleep without opening the lid, you can use an external mouse. However, this method may not work for all laptops, especially older models. Newer motherboards typically support this feature, but it's a good idea to check your laptop's specifications to be sure.
To use this method, you'll first need to configure your laptop's power settings. Here are the steps you can follow:
- Go to your Control Panel and find "Power Options".
- Navigate to "Advanced settings".
- Under "USB settings", set the "USB selective suspend" setting for "Plugged in" to "Disabled". This ensures that power is still supplied to your external mouse even when your laptop is in sleep mode.
- Next, under "Power buttons and lid", set "Lid close action" for both "On battery" and "Plugged in" to "Do nothing". This will allow your laptop to remain running even with the lid closed.
- Connect your external mouse to your laptop and ensure it is functioning properly before putting your laptop to sleep.
- When your laptop is in sleep mode, simply move your external mouse, and it should wake up.
It is important to note that if you are using a wireless mouse, you may need to ensure that the USB receiver dongle remains powered on even when the laptop is asleep. This can be achieved by disabling the "USB selective suspend" setting as mentioned in the previous steps.
Additionally, if you are using a Bluetooth mouse, you may need to customise your laptop's Bluetooth settings to allow wake-up functionality. You can refer to your laptop's documentation or contact the manufacturer for instructions specific to your model.

Try pressing any key on your keyboard
If your laptop is in sleep mode, you can wake it up by pressing any key on your keyboard. Sleep mode is a power-saving state that stops all actions on your laptop, and pressing a key on your keyboard can help bring it back to its normal, full-power operation within a few seconds.
However, this method may not work for all laptops. For instance, if you are using a laptop with a closed lid, simply pressing a key may not be enough to wake it up. In such cases, you may need to enable the "Wake on USB" or "USB Wake" option in your laptop's BIOS settings. This will allow you to wake up your laptop by connecting an external keyboard or mouse and pressing any key or button.
Additionally, if you are using a Bluetooth keyboard or mouse, you may encounter issues with waking up your laptop from sleep mode. This is because many laptop manufacturers do not allow Bluetooth devices to wake the computer from sleep mode due to the power consumption requirements of keeping the Bluetooth radio activated. If you are having trouble, try using a wired keyboard or mouse, or refer to your laptop's documentation or manufacturer for specific instructions.
It is worth noting that if your laptop is in hibernation mode, pressing a key on the keyboard may not be sufficient to wake it up. In such cases, you may need to press the power button or use a different method, such as the one suggested by a user, which involves attaching a balloon to a tube and the other end to a balloon pump.

Disable the lid switch
Disabling the lid switch on a laptop is a potential solution to waking up the device from sleep mode without opening the lid. This method, however, may not be applicable to all laptop models and may require some technical adjustments.
For HP laptops, specifically the Elitebook series, the only way to disable the lid switch is by physically cutting and hacking into the laptop, which will void the warranty. This method involves locating the reed switch and either disabling it by disconnecting it or cutting a circuit board trace. On the other hand, Dell offers some rugged laptop models with an extra setting in the BIOS for disabling the lid switch.
For Windows users, you can try changing what closing the lid does by going to the Control Panel, selecting "Hardware and Sound," then "Power Options," and finally, "System Settings." Here, you can choose the option for "Do Nothing" when the lid is closed, which effectively disables the lid switch.
If you are using an external monitor with your laptop, there are additional steps you can take. First, plug in an external mouse. Go to Device Manager or use the keyboard shortcut Win + X followed by M. Double-click on the external USB pointing device, and on the Power Management tab, ensure that "Allow device to wake computer" is checked.
It is important to note that while these methods may work for some laptops, they may not be universally applicable. The specific steps to disable the lid switch can vary depending on the laptop model and the operating system in use.
