2. How to Use Your MacBook With a Monitor and the Lid Closed

Plugin your external monitor into an available USB port on your Mac, using a Mini DisplayPort-to-DisplayPort cable if necessary. If you don’t have one of these cables, any full-size DisplayPort male to male will work. You can also use an HDMI or DVI cable if your monitor supports one of those connections.

How to Use Your MacBook With a Monitor and the Lid Closed

Using the built-in display: If you close the lid of your laptop and press a key, you’ll find that all commands are directed to the main screen of your Mac (the built-in display). To change this behavior, go to System Preferences and click Displays. Now, select the second screen from the left in the Arrangement tab to activate it as your main display.

Step 1: Open The System Preferences app

Step 2: Click On The Display Tab From here on out, you will use the external monitor instead of the laptop’s internal one whenever you close your MacBook’s lid. The reverse is also true: all activity will focus on your laptop’s screen instead of the monitor when you open the screen. Make a mental note of this feature to avoid confusion in the future.

Step 3: Click On The Screens Tab Now that you’ve designated an external monitor as your primary screen, it should be listed as the main screen in your screen preferences. If it isn’t, click it to select it as the primary screen.

Step 4: Activate The Second Screen After you use the external monitor as your primary screen, walk through steps 1 and 2 again, but instead of selecting a new screen, leave the screen drop-down menu set to “Mirror Displays.”

Step 5: Add a Second Screen Now that you’ve designated your laptop screen as the primary screen, you can add an external monitor. Connect your second screen to a USB or Thunderbolt port on your Mac. Then, in System Preferences > Displays > Arrangement, select it as the secondary screen.

If you use your MacBook at home with a 24-inch external monitor, for example, and then head off to work with just the laptop display, you’ll want to change the mirroring option so you can also take advantage of your extra screen when you arrive at work.

If both screens are set up as primary displays, then right-click on their respective menu bars and uncheck the Mirror Displays box.

Note: If you attached two external monitors, one would be labeled “Default Display” while the other will be called “2nd screen.”

Step 6: Use Your Laptop With An External Monitor Now that your MacBook’s screen has been designated as a secondary screen, you can use it as usual while your second screen shows whatever’s on the main screen of your Mac. If you want to change anything, return to System Preferences > Displays > Arrangement and make the appropriate adjustments.

Step 7: Control Your Monitors’ Brightness With a MacBook Pro, You have a brightness control for each of your monitors. If you’re using a MacBook Pro, the brightness control is located in System Preferences > Displays next to the Arrangement tab.

3. Warnings About Keeping Your Laptop on When Closed

Keeping your laptop running after it’s been closed may reduce the lifespan of its battery and could shorten its life span. The reason: if the laptop is off, there’s no draw on the battery. When a laptop is in use, the CPU, hard drive, and other parts run continuously to power the screen and other components.

Warnings About Keeping Your Laptop on When Closed

When it’s closed, the battery keeps the RAM powered for use by programs that may need to access memory while the laptop is off. Closing a laptop also turns off its cooling fans, so if you’ll be using it again within an hour or two, keeping it on could be a good idea — otherwise, turn it off.

If you want to keep your laptop on, but you’re worried about power consumption, consider buying a spare battery. You can swap batteries without turning off the laptop- be sure that when you put the first one back in, the other one is fully charged or plugged into an AC outlet; otherwise, the second battery may drain while it’s not being used.

Note that your laptop screen, keyboard, and touchpad won’t work if your laptop is in sleep or hibernate mode unless you have a wireless mouse and pointing device. Some laptops don’t power these devices while the machine is asleep or hibernating. If the device doesn’t work by default but can be powered on automatically with the computer, consider exploring your device’s settings to adjust this.
