So, you think your Mac is flawless and free of issues? Think again. As with other computers, it may experience problems.
And just recently, numerous users have reported instances where their Macs always restart while on sleep mode. Simply said, when they put their Mac to sleep, after a few minutes or hours, the system will just wake up on its own.
But no, this isn’t some sort of sorcery or black magic. It’s not even a doing of an elemental or an out-of-this-world being. It’s simply an issue with Macs. A number of solutions have been suggested already. We’ll discuss more of them below. But before we proceed to possible solutions, allow us to share with you some causes why your Mac always restarts on sleep mode.
If you have discovered that your Mac suddenly woke up from sleep mode even without interaction, just relax. Again, it’s not a ghost. Rather, it has something to do with your system settings.
When you put your Mac on sleep mode, it will then power down but stay on standby. This means that even if the majority of your Mac’s components are shut off, including the processor and storage drives, the memory will continue running so that it can quickly wake up and pick up where you have left off.
Although the sleep mode is great to use when you don’t want to shut down your Mac, but want to save power, oftentimes it is rather pointless and futile as it could trigger errors and problems.
First off, why is there a sleep mode? Is it a mandatory function? Of course, it’s not. But it is quite handy for Mac owners who frequently use their devices and don’t want to completely turn them off every time.
To set up your Mac’s sleep mode, you simply have to follow these steps:
You don’t have to dwell so much thinking whether or not you should put your Mac on sleep mode. It’s an issue that has many quick fixes.
If you encounter Mac restarting problems while it’s on sleep mode, here are some solutions to try:
Among the biggest culprits of Mac restarting problems are USB devices that you have currently plugged in, such as keyboards, mouse, or headsets. So, to check if they are actually causing the problem, follow these steps:
In case you are wondering why a USB device is considered a culprit, well, the answer is simple. It is possible that one key on your keyboard or one button of your mouse is malfunctioning. It might be sending that information to your Mac; hence it cannot go to deep sleep.
If your Mac is currently connected to the Internet, it is possible that it will wake up from sleep because there is some on-going internet activity or other crucial network processes.
This is likely to happen if your Mac is connected to a network drive or a server. Whenever a network drive is active, it could trigger your Mac to wake up. This is also the case for Printer, File, or iTunes sharing.
To prevent these things from happening, do the following:
Network activities and faulty USB devices are two common reasons why your Mac wakes up from sleep mode. But if they remain unfixed at this point, we suggest that you try to reset the System Management Controller (SMC).
The SMC controls your Mac’s power manager. It stores all the options and settings for your Mac when it sleeps. When it becomes corrupted, it can trigger random wake-ups.
To fix problems with your Mac’s SMC, you can just reset it. Here’s how you do it:
If you are using a MacBook, here’s how you reset the SMC.
Oftentimes, your Mac wakes up from sleep mode because of unnecessary or junk files that are messing with your system processes. To ensure they don’t interfere with important processes, make it a habit to delete files you don’t need.
However, identifying unnecessary or junk files may be confusing at times. Thus, we recommend that you use a third-party Mac repair tool. With a reliable Mac repair tool, you can ensure no junk files will ever take up valuable system space and affect your Mac’s important system processes.
If all else fails, your last resort is to take your Mac to the nearest Apple Store. Let any of the technicians check your Mac for any serious hardware or software problems and have them all repaired. Don’t worry, because these repairs won’t cost a lot, especially if your Mac is still on warranty.
Did we also mention that this solution is highly recommended if you are in doubt with your technical skills?
You really don’t need to be scared when your Mac keeps restarting while it’s on sleep mode. Sleep-wake problems like this are common among Mac devices. All you have to do is to try any of the suggested fixes above and you should be alright.
