The best way to make your Macbook Pro sleep when the lid is closed is to enable the NoSleep power management extension. Pavel Prokofiev, who was frustrated by the lack of power options on the Mac, developed the NoSleep extension and generously shared it with the community. The extension is free to download, but if you’d like to support the developer, a donation button is included on the project page.
NoSleep
If you have an external monitor connected to your MacBook Pro, then you’ve probably wondered how to prevent it from going into sleep mode. Using NoSleep is as simple as ticking a box in the System Preferences. You can also configure the sleep mode timer and activate it on different events, such as when the laptop is connected to an external monitor. This extension also allows you to prevent your Mac from going into sleep mode when the lid is closed.
The main reason your Mac may be woken up is active processes and network activity. Active processes include system background tasks and applications. You can wait for them to complete, quit them, or Force Quit them if they are not responding. But it is better to do this when the system isn’t actively working. To prevent Mac from going into sleep mode when you are downloading a large file or presenting, you should enable NoSleep.
You can connect an external monitor to your Mac with a compatible display adapter. Mini Display to DVI adapters are available for Thunderbolt and Mini DVI ports. Once your desktop appears on the external monitor, you can close the lid and continue using your Mac. Once you connect an external keyboard and mouse, the display will continue to display. Then you can use the external monitor as a second display.
Lungo is another app that makes changing your Mac sleep time easy. This utility lives in the menu bar and lets you customize your Mac’s sleep time. You just need to click the icon and set the desired duration. You can also change this setting manually by using a terminal app or shell script. The app will allow you to set a number of preset periods for your Mac.

InsomniaX
The InsomniaX for Macbook Pro extension will override sleep mode on MacBooks when the lid is closed. This application was developed by Pavel Prokofiev, who was frustrated by Apple’s lack of native power management options. If you have an external monitor, you can use an external keyboard and mouse. To prevent sleep when the lid is closed, check the box to enable the “CPU safety” feature. To make your MacBook not sleep when the lid is closed, set keyboard shortcuts for idle and lid sleeping.
The program has two major benefits. First, it helps your laptop stay awake. The second benefit is that it conserves battery life. When the lid is closed, the MacBook will save more energy, ensuring that you can continue to use the computer without the need to worry about battery drain. However, if you’re concerned about the battery life of your Mac, you can try using an external monitor.
The third benefit of InsomniaX for Macbook Pro is that it is a free download and you can use it for as long as you need it. The app is available for Mac OS X, Windows, and iOS. For more information, visit the official website for InsomniaX for Macbook Pro. You can also download the app here. You can also try a free trial version to see if it works for you.
To enable InsomniaX for Macbook Pro sleep when lid closes with external monitor, you need to launch the app’s icon from the menu bar and click on the “Set Lid Sleep Hot Key” option. After that, simply press the desired keys to set as hotkeys. The external monitor will wake up the Mac notebook at the same time. Then, if you want to enable the Lid Sleep feature when connected to AC adapter, you can also configure InsomniaX for Macbook Pro to disable this as well.
Safe mode
If you are having trouble working on your MacBook Pro when its lid is closed with an external monitor connected, you may have trouble with the battery life. When you try to charge the MacBook with an external monitor connected, you may notice that the screen will go black or turn off. To fix this, follow these steps. Open System Preferences and go to Battery. Click on the Energy Saver tab. On the next screen, click on Power Adapter and change the setting to “On.”
When the lid is closed, you can launch Safe Mode by holding the spacebar key. The Apple logo appears in the bottom-left corner of the screen. If the screen is still active, you need to press the spacebar key on an external monitor to bring it back to its normal state. Once this is done, the MacBook will restart. Then, you can continue your work. You can also connect a second monitor if the first one doesn’t work.
The next step is to turn off Wi-Fi and any external monitor. To do this, first shut down the Mac. Make sure that it’s on a flat surface and well-ventilated. Next, hold down the D key to launch the Apple Diagnostic Test. Select the language that you want to run the test in. The entire process may take a few minutes. Once you’re done, your Mac should be operating smoothly again.
If the display of your MacBook is not working properly, try updating the monitor’s software and firmware. It’s possible that the monitor’s settings are not compatible with the MacBook’s resolution. If that’s the case, it’s best to check the documentation of your external monitor. When you have finished the installation process, reboot the Mac in Safe Mode and then select the Displays tab in System Preferences. Select the resolution that matches the resolution of your external monitor.
If the screen on your MacBook Pro is not working, you should power it off for at least 20 seconds, then turn it back on. While the screen is turning on, hold down the Shift key until you see a login screen. After the login window appears, you should see a message saying “Safe Boot.” If you don’t see this, you’ll need to login again or wait a few minutes until the laptop boots up normally.
Resetting the System Management Controller
If your MacBook is sleeping with the lid closed, resetting the SMC may be the solution. This process will reset the Mac’s power and battery management settings. Apple has provided information about resetting the SMC on their support page. Running outdated applications can affect your Mac’s performance. If you’re experiencing random battery drainage, you should update any applications that are slowing your machine down.
If you can’t open the power menu, try holding down the power button for ten seconds, then release it. The MacBook will then shut down. When the screen turns off, press the power button again and the computer will reboot. After the restart, unplug all peripherals and reconnect them. The system should now restart. If the problem still persists, you can try the reset method again.
Depending on the cause of the problem, there are several ways to fix the problem. Using a third-party external monitor, you can attach an external monitor and continue working. This method is a quick fix for your MacBook’s sleep issue. Ensure that you have a valid AppleCare warranty before sending it for repair. Otherwise, you may have to pay more.
Before resetting the SMC, you must identify the hardware model of your machine. If you don’t know, SMC is a chip incorporated into the motherboard of the computer. The SMC controls several core functions of a Mac and is responsible for everything from battery life to power distribution. It also controls power consumption, LED lighting, and sleep/wake modes.
Resetting the SMC can fix many other problems. A laptop without a SMC can easily overheat and deplete its battery. Resetting the SMC can also help troubleshoot a bug, but you should be aware that the process varies for different desktops and laptops. The final result will erase all your personalized settings and restore your computer’s default settings.
If your MacBook Pro has the T2 chip, you can manually reset the SMC. To reset the SMC, hold down the power button until your MacBook shuts down. You will lose all open work in this step, so it’s important to follow the steps below carefully. Once you’ve reset the SMC, you can try to turn your Mac on by restarting it.
