Many people use their laptops as desktop replacements, connecting them to an external monitor and keyboard. However, this can be frustrating when you need to open and close the lid just to press the power button. While there is no universal solution, some methods to wake a laptop from sleep without opening the lid include: disabling the sleep function when the lid is closed, enabling the Wake on USB option in the BIOS, and using an external mouse or keyboard. Some people have suggested low-tech solutions, such as attaching a balloon to a tube and inflating it to press the power button. Others have suggested breaking the laptop lid switch, but this is not recommended as it may damage the laptop.

What You'll Learn
Check BIOS for 'wake-on-USB'
To wake up your laptop from sleep without opening the lid, you can check your BIOS settings to enable the "Wake on USB" option. BIOS, which stands for Basic Input/Output System, is the firmware that your computer uses to manage hardware features and boot up.
- Access the BIOS settings: To do this, restart your computer and press a specific key or key combination during the boot process. The key varies depending on your device, but it is commonly F2, F10, F12, or Delete. If you are unsure, check your laptop or motherboard manual for instructions.
- Navigate to the "Power" or "USB" settings: Once you are in the BIOS menu, use the keyboard arrows to navigate through the options. Look for sections labelled "Power Management," "USB Configuration," or similar titles.
- Find the "Wake on USB" option: Within the power or USB settings, look for an option labelled "Wake on USB," "USB Wake Support," or something similar. This option may be located within a sub-menu, so carefully browse through the available settings.
- Enable the "Wake on USB" option: If the "Wake on USB" option is disabled, use your keyboard to change the setting. This may involve pressing a specific key to toggle the option, or using arrow keys to select the desired setting and then pressing Enter to confirm.
- Save and exit the BIOS: After making the necessary changes, follow the on-screen instructions to save your changes and exit the BIOS. This may involve navigating to a "Save and Exit" option or pressing a specific key combination, such as Ctrl + S to save and Ctrl + Q to exit.
By enabling "Wake on USB" in the BIOS, you can now wake up your laptop from sleep by using an external keyboard or mouse, without the need to open the lid. Please note that this method may not work for waking the laptop from hibernation or a full shutdown, as it specifically applies to the sleep mode.

Use an external monitor
If you want to wake your laptop from sleep without opening the lid and while using an external monitor, there are a few methods you can try.
Firstly, check your BIOS settings to see if it supports wake-up on USB. If it does, you can wake your laptop up with an external keyboard. You can also try a Wake-on-LAN utility, but this will require a second computer or device like a phone.
Another method is to change what closing the lid does by setting it to 'Do Nothing'. You can do this by hitting the Windows key and typing 'lid', or by going to the Control Panel, then Hardware and Sound, then Power Options, and finally System Settings. You can also plug in an external mouse and go to the Device Manager by hitting the Windows key, 'X', then 'M'. Double-click the external USB pointing device, and on the Power Management tab, ensure that 'Allow device to wake computer' is checked. When you're finished using the built-in screen, you can cycle through projector options to enable the monitor with the Windows key and 'P'.
Additionally, you can try getting a dock that can power the laptop, or plugging it in at your desk. This way, the laptop will not turn off when closed.
Finally, if you have a Windows laptop, you can try adjusting the driver from the software side. However, this method may not always work as the hardware takes precedence when the laptop is asleep.

Change power options in Control Panel
To change power options in the Control Panel, follow these steps:
Firstly, go to the Start menu and select Settings. From there, go to System, then Power & Sleep. Here, you can adjust your power and sleep settings. Under Screen, select how long you want your device to wait before turning off the screen when inactive. Under Sleep, select how long you want your device to wait before going to sleep when not in use.
If you want more power-saving options, select Additional Power Settings. Here, you can change how your device uses power. You can also select Change settings that are currently unavailable to access more options. Under Shutdown settings, you can select the Hibernate checkbox if it is available. Hibernate mode saves your computer's current state and shuts off power, then reloads files when the power button is pushed. It takes longer to resume from hibernation than sleep, but it uses little to no power.
If you want to wake your laptop from sleep without opening the lid, you can try the following:
- Check if your BIOS supports wake-up on USB and enable it. Then, you can wake your laptop with an external keyboard or mouse.
- Change what closing the lid does by setting it to 'Do Nothing' in the Control Panel. Plug in an external mouse and ensure that 'Allow device to wake computer' is checked in the Power Management tab of the Device Manager.

Use a 'wake-on-LAN' technique
Wake-on-LAN is a networking standard that allows a computer to be turned on or woken up from a sleep or powered-off state by a network message. This message, often called a "magic packet", is sent from a WoL-enabled device over the network to the target computer.
To use Wake-on-LAN, you will need to ensure that both the BIOS and the operating system of the target computer are configured to support Wake-on-LAN. In the BIOS, WoL is usually enabled in the power management settings. In the operating system, the network adapter properties should have the WoL feature enabled, allowing the adapter to respond to the magic packet.
For Windows PCs, enabling WoL in the BIOS allows the computer to wake from a powered-off state, sleep, or hibernation. To enter the BIOS menu, reboot your PC and press a key at the boot screen—usually Delete, F2, or some other function key. Once you enter the BIOS menu, look for settings named "Wake on LAN", "Onboard LAN Boot ROM", or something similar.
It is important to note that Wake-on-LAN is designed to wake up another computer on your network, so it will not work for computers on another network. Additionally, while most modern Ethernet adapters will support Wake-on-LAN, wireless adapters rarely do. If you are using a wireless adapter, you will need to send the magic packet over Wi-Fi, but the receiving computer will need to be plugged in via Ethernet.
There are several software tools designed for WoL that can be used to wake up a device, such as Chrome Remote Desktop, NirSoft's WakeMeOnLan, Depicus, Mocha WOL (iOS), and Wake On Lan (Android).

Break the laptop lid switch
Breaking the laptop lid switch is one way to wake a laptop from sleep without opening the lid. However, it is not a recommended method as it may void the warranty and cause other issues.
To physically break the laptop lid switch, you would need to open the laptop and locate the switch, which is usually near the hinge or the screen. Once located, you can try to disconnect, cut, or desolder the switch from the laptop's circuitry. This will involve prying open the laptop case, which may cause damage if not done carefully.
Another potential method is to remove or disable the sensor that detects when the lid is closed. This could involve cutting or desoldering wires or physically removing a magnet within the screen that triggers the sensor. Again, this requires opening the laptop and may cause damage.
It is important to note that breaking or disabling the lid switch may have unintended consequences, such as the laptop not being able to detect when the lid is closed and, therefore, not going into sleep mode properly. This could drain the battery or cause overheating issues.
Before attempting any physical modifications, it is recommended to explore software solutions, such as changing power settings in the Control Panel or BIOS to set the laptop to "Do Nothing" when the lid is closed. This can often achieve the desired result without the need for any physical alterations.
