Enabling Wake-on-LAN (WOL)
Wake-on-LAN (WOL) is a feature that allows you to turn on your computer remotely over a network connection. It’s one of the most reliable ways to power on your closed laptop, especially if it’s connected to a wired network.
Configuring BIOS/UEFI Settings
The first step is to enable WOL in your laptop’s BIOS or UEFI settings. These settings are accessed before the operating system loads, usually by pressing a specific key during startup (e.g., Delete, F2, F12, Esc). The key varies depending on the laptop manufacturer. Check your laptop’s manual or the manufacturer’s website for the correct key.
Once you’re in the BIOS/UEFI settings, navigate to the “Power Management” or similar section. Look for an option related to “Wake-on-LAN,” “Power On By LAN,” or “Remote Wake-up.” Enable this option. Save the changes and exit the BIOS/UEFI.
Important Note: The exact wording and location of the WOL setting may vary depending on your laptop’s BIOS/UEFI version. If you can’t find it, consult your laptop’s manual or search online for instructions specific to your model.
Configuring Operating System Settings (Windows)
After enabling WOL in the BIOS/UEFI, you need to configure it within your operating system. Here’s how to do it on Windows:
- Open the Device Manager (search for “Device Manager” in the Start menu).
- Expand the “Network adapters” category.
- Right-click on your Ethernet adapter (the one connected to your network) and select “Properties.”
- Go to the “Power Management” tab.
- Make sure the following options are checked: “Allow this device to wake the computer,” “Only allow a magic packet to wake the computer,” and “Wake on Magic Packet.”
- Go to the “Advanced” tab.
- Look for a property called “Wake on Magic Packet” or similar. Make sure it’s enabled. Also, look for options related to “Energy Efficient Ethernet” or “Green Ethernet” and disable them, as they might interfere with WOL functionality.
- Click “OK” to save the changes.
Configuring Operating System Settings (macOS)
Enabling WOL on macOS is relatively straightforward:
- Go to System Preferences -> Energy Saver.
- Ensure that “Wake for network access” is checked.
Sending the Magic Packet
To actually turn on your laptop using WOL, you need to send a “magic packet” to its network adapter. This packet contains the laptop’s MAC address and tells the adapter to power on the computer. There are various tools and apps available for sending magic packets.
For example, on Windows, you can use a free utility like “WakeMeOnLan” by NirSoft. Simply download and run the program, select your laptop from the list of detected devices, and click “Wake Up.”
On macOS, you can use the built-in “wakeonlan” command in the Terminal. First, you need to know your laptop’s MAC address. You can find it in System Preferences -> Network -> (Your Ethernet Adapter) -> Advanced -> Hardware. Then, open Terminal and type: wakeonlan [MAC address]. Replace [MAC address] with your laptop’s actual MAC address.
There are also mobile apps available for both Android and iOS that allow you to send magic packets from your smartphone or tablet. Search for “Wake on LAN” in the app store.
Security Considerations: WOL can pose a security risk if not properly configured. Anyone on your network could potentially send a magic packet and turn on your laptop. To mitigate this risk, consider enabling MAC address filtering on your router to only allow magic packets from specific devices.
Using an External Keyboard or Mouse
Another common method to turn on a closed laptop is by using an external keyboard or mouse. This method relies on the laptop’s ability to wake up from sleep or hibernation when it detects input from a connected device.

Why would I want to turn on my laptop while closed?
Turning on your laptop while closed can be incredibly convenient in several situations. For example, you might want to connect your laptop to an external monitor and use it as a desktop replacement without the laptop screen taking up space. It also allows you to initiate tasks remotely, such as running scripts or accessing files, without needing to physically open the device.
Another practical application is creating a cleaner workspace. By keeping the laptop closed, you minimize visual clutter and distractions. This setup is particularly useful for presentations or streaming, where the laptop’s internal display is not needed and only the external display is relevant. It provides a streamlined experience and improves the overall aesthetics of your workstation.
Is it safe to run my laptop closed all the time?
While running a laptop closed is generally safe, continuous operation in this state can potentially affect its temperature. Laptops are designed with cooling systems that dissipate heat, and closing the lid can restrict airflow, especially if the vents are located near the hinge or underside of the device. It’s essential to monitor your laptop’s temperature and ensure it doesn’t overheat during prolonged use.
To mitigate potential heat issues, consider using a laptop stand that elevates the device, providing better airflow. Furthermore, check your laptop’s manufacturer specifications for optimal operating conditions and recommended temperature ranges. If you notice excessive heat buildup, consider allowing the laptop to cool down periodically or adjust the workload to reduce thermal stress.
How do I configure my laptop to turn on when I open the lid?
Configuring your laptop to turn on when you open the lid is typically managed through the BIOS or UEFI settings. Accessing these settings usually involves pressing a specific key (e.g., Delete, F2, F10, or Esc) during the startup process, which varies depending on the manufacturer. Once in the BIOS/UEFI, look for power management options related to lid behavior, often labeled as “Lid Open Action” or similar.
Within the power management settings, you should find an option to specify whether the laptop should power on or remain off when the lid is opened. Select the appropriate setting to enable the “power on” functionality. Save the changes and exit the BIOS/UEFI. After restarting, your laptop should now automatically turn on whenever you open the lid, streamlining your workflow.
What if my laptop doesn’t have a “power on lid open” setting?
If your laptop lacks a direct “power on lid open” setting in the BIOS/UEFI, there might still be alternative power settings you can adjust. Look for options related to sleep states, such as “Hybrid Sleep” or “Hibernate,” and experiment with disabling them. Sometimes, these features can interfere with the desired lid behavior. Also, ensure that “Fast Startup” is enabled in your operating system’s power options.
If these options are unavailable or ineffective, you may need to rely on external peripherals to wake the laptop. Connect a USB keyboard or mouse and enable the option to wake the computer using these devices. This workaround allows you to remotely activate the laptop even when the lid is closed. Check your operating system’s device manager settings to find the “Power Management” tab for these peripherals and enable “Allow this device to wake the computer.”
How can I remotely wake my laptop if it’s completely powered off?
Remotely waking a completely powered-off laptop requires enabling Wake-on-LAN (WOL) in both the BIOS/UEFI and your operating system’s network adapter settings. First, access the BIOS/UEFI settings during startup and locate the power management or advanced settings sections. Look for a WOL option and enable it. Save the changes and exit the BIOS/UEFI.
Next, in your operating system, navigate to the network adapter settings (usually through Device Manager). Select your network adapter and access its properties. In the Power Management tab, ensure that “Allow this device to wake the computer” and “Only allow a magic packet to wake the computer” are both checked. Additionally, you’ll need a WOL application on another device to send a “magic packet” to your laptop’s MAC address, triggering it to power on. Keep in mind that WOL usually requires a wired Ethernet connection and may not work with Wi-Fi, depending on your hardware and BIOS settings.
Will using an external monitor affect the laptop’s performance when closed?
Using an external monitor while the laptop is closed can have a slight impact on performance, primarily due to the laptop’s integrated or dedicated graphics card needing to output video to an external display in addition to managing internal processes. However, this performance impact is generally minimal for most everyday tasks like browsing, document editing, or media consumption.
If you’re performing graphically intensive tasks such as gaming or video editing, the impact might be more noticeable. To mitigate potential performance bottlenecks, ensure your laptop’s drivers are up to date and that the external monitor is connected using the optimal port (e.g., HDMI or DisplayPort). Additionally, consider adjusting graphics settings within your operating system and specific applications to prioritize performance over visual fidelity if necessary.
What should I do if my laptop isn’t responding to the lid being opened?
If your laptop isn’t responding to the lid being opened, start by checking the power settings within your operating system. Navigate to the Power Options (usually found in the Control Panel or System Settings) and ensure that the “Lid Open Action” is configured correctly. Verify that the setting specifies either “Do nothing” or “Sleep” rather than “Shut down” or “Hibernate.” Additionally, check if any power-saving modes are enabled that might be interfering with the automatic wake-up function.
If the power settings are configured correctly, the issue may be related to outdated or corrupted drivers. Update your display drivers and chipset drivers, as these components directly influence the laptop’s ability to detect and respond to the lid opening. In rare cases, the lid sensor itself may be faulty, requiring professional repair or replacement. Consult your laptop’s manufacturer support resources for troubleshooting steps specific to your model.
