Sleep mode is one of the most critical parts of any computer system. It consumes very little power and keeps your machine in a low-energy state while still allowing it to perform some tasks such as maintaining network connectivity or running scheduled maintenance scripts.
Finding the reason why you are so frustrated with your Mac turning off every time it is in sleep mode can be difficult as this may interfere with your workflow and cause inconvenience. This can be caused by a multitude of things such as software bugs or hardware problems.
Luckily, there are a number of steps one can take to troubleshoot and fix this issue. We will go through 8 different solutions which should help resolve the problem in this guide.
Here are 8 solutions to fix My Mac keeps shutting down in sleep mode issues:
Reset NVRAM/PRAM :
Non-Volatile Random Access Memory (NVRAM) or Parameter RAM (PRAM) saves important settings that control various system functions including what your Mac does when it goes to sleep mode. Resetting NVRAM/PRAM usually fixes sleep mode related problems.
- Shut down the Mac then turn it on again but immediately hold Command, Option, P, and R at the same time until you hear a second startup chime sound after which you can release them.
Check Energy Saver Preferences :
Sleep mode might trigger unexpected shutdowns if Energy Saver preferences have been set incorrectly hence causing this perplexing issue.
- Open System Preferences from Apple menu and select ‘Energy Saver’.
- Check your desired settings under both Display Sleep tab as well as Computer Sleep tab
- make sure they match what you want them to be before observing for further issues.
If the issues are not fixed even after trying the this method then move on to the next method.
Disable Power Nap :
Enabling Power Nap feature in macOS allows your computer do some tasks even while asleep such as receiving new mail or updating software but sometimes doing so may lead into troubles with regards to shutting down during sleep mode.
- To disable power nap feature go to System Preferences.
- Energy Saver then uncheck ‘Enable Power Nap‘ option available for both battery powered devices and those connected directly to an electrical outlet adapter.
- After disabling this function try putting back into sleep and see if still shuts down unexpectedly .
Check for Software Updates :
sometimes sleep mode doesn’t work properly due to bugs at different levels of software stack including firmware, operating system kernel or device drivers among others.
- Click the Apple menu and select “System Settings”.
- Choose “Software Update” from the list.
- Select “Update Now” or “Upgrade Now” if updates are available carefully examine if any updates were interrupted and are pending. If so,
- enable the update and wait for it to be installed.
Apple often releases updates which fix these kinds of problems so always ensure that you have them installed. If you are still having issues then try the next method.
Reset SMC (System Management Controller) :
The System Management Controller (SMC) is a chip on Intel-based Macintosh computers that controls all power functions. These include sleeping and waking up from sleep, shutting down or restarting, thermal management, LED indicators for sleep/wake status etcetera.
- If there are issues with this controller then resetting it may help resolve them .
- To reset SMC switch off the mac , then simultaneously press Shift-Control-Option-Power buttons and hold them down for about ten seconds before releasing .
- Press power button once again afterwards to turn on the Mac and verify if problem persists.
Check for Hardware Issues :
Sometimes sleep mode fails because of hardware faults like faulty battery or power adapter among others.
- Click on Apple menu bar item located top left corner followed by ‘About This Mac’,
- then click ‘System Report’ button and look under ‘Power’ section within left pane where you will find information about battery’s condition such as cycles count , full charge capacity (mAh), health status (%) etcetera.
- any warnings here could indicate need for replacement .
You can also try using different adapter/charger plus connecting directly into wall socket instead of using extension cord just in case problem lies with outlet strip itself .
Review third party software :
There are times when sleep mode operations get interrupted by third-party software or drivers.
You should look at the applications you have installed on your Mac and uninstalling or updating any software that could be conflicting with it. Give priority to utilities or system extensions claiming to optimize performance or manage power settings.
Perform a Clean Installation of macOS :
If all other methods fail, performing a clean installation of macOS can help fix stubborn sleep mode problems. However, before you proceed make sure to back up important data.
- Afterward restart your Mac while holding down Command and R key combination this will allow you to enter Recovery mode where after erasing your hard drive reinstall macOS again.
- Then watch out if the problem will still continue after reinstalling macOS.
Final Thoughts
Try these 8 troubleshooting methods systematically first, check for software conflicts, then look for possible app conflicts, then check for hardware problems. It’ will take some patience, but hopefully you will be able to get your Mac to sleep normally again without any unexpected shutdowns.
