Is your Mac experiencing persistent sugar spikes? You may notice that it suddenly stops working when you close the lid. The Apple logo on your MacBook continues to glow, and you can see a light leak from underneath the lid indicating that the display is still on.

There are a number of factors that can contribute to your MacBook always working when it shouldn’t. If it’s a third-party accessory or software problem, you can fix it yourself. If it’s a hardware problem, it may need a slightly expensive repair. Either way, go through the options.
Reset SMC
The system management controller handles lights, power, performance, and more in your MacBook. Something wrong in SMC could be the cause of your Mac not going to sleep when you close the lid.
If you think resetting the SMC might be to fix the problem, it should be quick and painless for your computer. First, turn off your MacBook and plug in the power adapter. Hold down Switch, Control, Options And Power keys at once and then release them all at once. Turn your computer back.
Use your Mac normally for a few minutes, then close the lid to see if it goes to sleep. If it works, congratulations, you can stop here. If not, fear not, there are a few other options.
Reset NVRAM (or PRAM)
There’s one more thing you should try resetting so it doesn’t affect your Mac in any way. It’s a fixed random-access memory that can solve power-related problems. On older Macs, it was called PRAM.
Either way, to reset it, shut down your Mac. Prepare those fingers for the new position when it comes off. Then turn your Mac back on, and when the screen turns on, press and hold Commands, Options, P and R. When the machine restarts on its own, let go.
Let the machine boot up, then use it normally. After a few minutes, try closing the lid again. If your Mac still won’t sleep, try option number three.
You may not know it, but some apps or services running in the background can prevent your Mac from going to sleep. To find out if this is the case and what apps are causing the insomnia, there is a simple Terminal command.
Open Terminal from your Applications folder (usually in the Utilities subfolder) or by typing “Terminal” in Spotlight Search. Then type in this command: pmset -g confirms. Fight Enter on your keyboard.
You’ll see a long list of system-wide “confirmations” and a corresponding number. “1” equates to on or true and “0” equates to off or false. Check out a few sleep entries like “PreventUserIdleDisplaySleep” and see the number note.
If you notice that the system indicates something is preventing the computer from going to sleep, scroll down to the second section labeled “Listing by Owning Process”. Here you can see which task or application, if any, is interfering with sleep.
Armed with this knowledge, you can access those apps and exit them or stop any task. Then try closing the lid.
It could be hardware, let a genius help you
If your MacBook still won’t go to sleep when you close the lid, it could be a hardware problem at this point. If you don’t have AppleCare, you won’t be happy with the price.
Not your usual bar | shutter
When you take your MacBook to the Genius Bar at your local Apple Store, Apple sends it in to fix things whether you want to fix them or not, and charges a flat repair fee. This varies from location to location.
This ended up happening to my MacBook and the repair fee was $280. I couldn’t justify paying that amount for such a minor issue, so as some other damage accumulated I ended up bringing it in so they could all be fixed in one batch. That is your best bet.
Tip: Living with a MacBook that doesn’t sleep on its own isn’t too bad either. If you don’t want to pay for a hardware repair, just make sure to press the Power button on your keyboard to manually put the keyboard to sleep before you close the lid.
