As a Mac user, you might have wondered what happens when you close the lid of your laptop. Does it go to sleep immediately, or does it continue to run in the background? In this article, we’ll delve into the world of Mac sleep mode, exploring what happens when you close the lid, how to customize the sleep settings, and the implications of sleep mode on your Mac’s performance and battery life.
What Happens When You Close the Lid of Your Mac?
When you close the lid of your Mac, it doesn’t necessarily mean that it goes to sleep immediately. The default behavior of a Mac is to go to sleep when the lid is closed, but this can be customized to suit your needs. When your Mac goes to sleep, it enters a low-power state that helps conserve battery life and reduce heat generation.
Understanding the Different Sleep Modes
There are two types of sleep modes on a Mac: Sleep and Deep Sleep.
- Sleep Mode: In this mode, your Mac’s CPU and memory are powered down, but the computer can wake up quickly when you open the lid or press a key. Sleep mode is designed to conserve battery life while still allowing your Mac to wake up quickly.
- Deep Sleep Mode: Also known as “hibernation,” Deep Sleep mode is a more aggressive power-saving mode that writes the contents of your Mac’s memory to the hard drive and then shuts down the computer completely. Deep Sleep mode is designed to conserve even more battery life, but it takes longer to wake up from this mode.

What happens when I close the lid of my Mac?
Closing the lid of your Mac triggers the sleep mode, which is designed to conserve energy and prolong battery life. When your Mac is in sleep mode, it shuts down most of its functions, including the display, hard drive, and other non-essential components. However, it still maintains a connection to the power source and can quickly wake up when you need it.
It’s worth noting that the sleep mode on Macs is different from the shutdown mode. When your Mac is in sleep mode, it can still perform some tasks, such as syncing data and receiving notifications. Additionally, sleep mode allows your Mac to wake up quickly, usually within a few seconds, whereas shutting down your Mac completely can take longer to start up again.
How does sleep mode affect my Mac’s battery life?
Sleep mode is designed to conserve battery life on your Mac. When your Mac is in sleep mode, it reduces power consumption by shutting down non-essential components, such as the display and hard drive. This can help extend the battery life of your Mac, especially when you’re not using it for an extended period.
However, it’s essential to note that sleep mode is not the same as shutting down your Mac completely. If you’re not planning to use your Mac for an extended period, it’s recommended to shut it down completely to conserve battery life. Additionally, if you’re using a MacBook, you can also consider using the “Power Nap” feature, which allows your Mac to perform tasks while it’s in sleep mode, but still conserves battery life.
Can I customize the sleep mode settings on my Mac?
Yes, you can customize the sleep mode settings on your Mac. To do this, go to System Preferences > Energy Saver, and then select the “Sleep” tab. From here, you can adjust the sleep timer, which determines how long your Mac will wait before going to sleep when it’s inactive. You can also adjust the “Power Nap” settings, which allow your Mac to perform tasks while it’s in sleep mode.
Additionally, you can also customize the sleep mode settings for your Mac’s display. To do this, go to System Preferences > Displays, and then select the “Arrangement” tab. From here, you can adjust the display settings, including the sleep timer, which determines how long your Mac’s display will stay on before going to sleep.
Will my Mac sleep when the lid is closed if it’s connected to an external display?
If your Mac is connected to an external display, it will not sleep when the lid is closed. This is because the external display is still active, and your Mac will continue to power it. However, if you close the lid and the external display is set to be the primary display, your Mac may still go to sleep after a period of inactivity.
To prevent your Mac from sleeping when the lid is closed and an external display is connected, you can go to System Preferences > Energy Saver, and then select the “Options” tab. From here, you can uncheck the box next to “Sleep when lid is closed,” which will prevent your Mac from sleeping when the lid is closed, even if it’s connected to an external display.
Can I wake up my Mac from sleep mode remotely?
Yes, you can wake up your Mac from sleep mode remotely using the “Wake on LAN” feature. To do this, you’ll need to enable the “Wake on LAN” feature on your Mac, and then use a remote access tool, such as Apple’s Remote Desktop or a third-party app, to wake up your Mac.
To enable the “Wake on LAN” feature on your Mac, go to System Preferences > Energy Saver, and then select the “Options” tab. From here, you can check the box next to “Wake for network access,” which will allow you to wake up your Mac remotely. You’ll also need to ensure that your Mac is connected to a network and that the remote access tool is configured correctly.
Will my Mac sleep when the lid is closed if it’s running resource-intensive tasks?
If your Mac is running resource-intensive tasks, such as video editing or software development, it may not sleep when the lid is closed. This is because these tasks require significant system resources, and your Mac may not be able to enter sleep mode while they’re running.
However, if you’re running resource-intensive tasks and you close the lid, your Mac may still try to enter sleep mode after a period of inactivity. To prevent this, you can go to System Preferences > Energy Saver, and then select the “Options” tab. From here, you can uncheck the box next to “Sleep when lid is closed,” which will prevent your Mac from sleeping when the lid is closed, even if it’s running resource-intensive tasks.
Can I schedule my Mac to sleep and wake up at specific times?
Yes, you can schedule your Mac to sleep and wake up at specific times using the “Schedule” feature in the Energy Saver preferences. To do this, go to System Preferences > Energy Saver, and then select the “Schedule” tab. From here, you can set a schedule for your Mac to sleep and wake up at specific times of the day or week.
Additionally, you can also use the “Automator” app to create custom workflows that can put your Mac to sleep or wake it up at specific times. To do this, you’ll need to create a new workflow in Automator, and then add actions to put your Mac to sleep or wake it up at the desired times. You can then save the workflow as an application and schedule it to run at the desired times using the “Calendar” app.
