Fix ‘Mac Not Sleeping When You Close the Lid’ Issue – Guide
There are several reasons why you may want to use your MacBook with the lid closed. You may want to connect an external monitor and set your MacBook aside to release up space on your desk (although you can always use both screens). Or maybe you want to download something or play music from your Mac without having to keep the lid open – you will find that as soon as you close the lid, the download will stop. If you want to prevent your Mac from hibernating when you close the lid, go to this section.
A related problem that you may encounter when using your Mac with the cover closed is that when you want to turn on the Mac, it looks like you have to open the cover to press the power button button. Fortunately, there is a workaround for this scenario that can be useful. Reading how to turn on your Mac without opening the cover here.back to menu ↑
Restart the SMC
The System Management Controller handles lights, power, performance and more on your MacBook. Something that went wrong with SMC may be responsible for your Mac refusing to sleep when you close the lid.
If you think a restart of the SMC may be in order to correct the problem, it is quick and easy for your computer. First, turn off your MacBook and plug in the power adapter. Hold down the Shift, Control, Option and Power keys at the same time, then release them all at the same time. Turn the computer on again.
Use your Mac normally for a few minutes, then close the lid to see if it falls asleep. If it worked, congratulations, you can stop here. Otherwise, don’t be afraid, there are a few more options.back to menu ↑
Restart NVRAM (or PRAM)
There is one more thing that you should try to reset and that should not affect your Mac in any way. It is non-volatile random access memory, which can handle energy issues. On older Macs, it is called a PRAM. Either way, to restart it, shut down your Mac. Prepare those fingers for new placement while it’s off. Then turn your Mac on again, and when the screen turns on, press and hold Command, Option, P, and R. When the computer restarts, release it.
Let the computer boot up, then use it normally. After a few minutes, try closing the lid again. If your Mac is not yet asleep, try option number three.back to menu ↑
Check for hidden apps using power
You may not know it, but some applications or services that are running silently in the background may be preventing your Mac from going to sleep. To find out if this is the case and which application is causing insomnia, there is a simple Terminal command.
Open Terminal in the Applications folder (usually in the Utilities subfolder) or by typing “Terminal” in Spotlight Search. Then enter this command: pmset -g assertions. Press Enter on your keyboard.
You will see a long list of system-wide “affirmations” and a corresponding number. “1” is equivalent to on or true and “0” is equivalent to off or false. Check out some of the sleep entries like “PreventUserIdleDisplaySleep” and see what numbers it contains.
If you notice that the system indicates that something is preventing the computer from hibernating, scroll down to the second section called “Listed by ownership process”. Here you can see which tasks or applications, if any, are preventing sleep.
Armed with this knowledge, you can access these applications and terminate them or interrupt any task. Then try to close the cover.back to menu ↑
Contact Apple Care
If your MacBook still doesn’t sleep when you close the lid, it’s probably a hardware problem right now. If you don’t have AppleCare, you won’t be too happy with the price. When you take your MacBook to the Genius Bar at your local Apple Store, Apple sends it to you for any and all repairs, whether you want to repair it or not, and charge a fixed repair fee. This varies from location to location.
This is finally over up being the case with my MacBook and the repair fee was $ 280. I couldn’t justify paying for such a small problem, so like some other accumulated damage, I finally brought it up so that everyone could be repaired in one round.back to menu ↑
