Having trouble with your Macbook that won’t turn on? If so, then this post might be able to help. Read on to find out what to do if your Macbook suddenly refuses to power on.
Possible reasons why your Macbook won’t turn on
Your Macbook has probably ran out of power and therefore it’s no longer able to power up unless it’s recharged. This is the most obvious reason. Nonetheless, it is also possible that something from within the system is halting the computer from executing the normal boot sequence. This is usually the case if the macOS had crashed and failed to execute the normal boot sequence.The worst possibility is that hardware damage is present on your Macbook.
Having said that, you’ll have to rule out three main factors in order to fix the problem. First is battery drain or power-related issues on the computer. Next, software-related issues and lastly, damage components.
Troubleshooting a Macbook that won’t turn on
To eliminate software-related factors that might have hindered your Macbook from turning on, try the following workarounds.
First workaround: Check it for power.
It is important to know if your Macbook shows any signs of power including startup sounds and light indicators.
To find out if any of these is present, press or long press the Power button on your Mac.
If the computer doesn’t show any power indications, check the physical connections. It might have been unplugged from the power source accidentally.
If you have confirmed that it’s plugged in but still doesn’t show any signs of power, check the power cable for any signs of damage. Also consider plugging the power cable into a different electrical outlet that’s functional. Then give it enough time to accumulate battery charge.
Second workaround: Power cycle your Macbook.
Performing this tweak is usually needed to fix your Macbook that’s not turning on due to a system crash. Your Macbook may not be responding or responding but couldn’t boot up normally. If you’re using a new Macbook with non-removable battery, try this tweak:
Press the Power button and hold it down for about 10 seconds.
If your Macbook is running but stuck on black screen, performing the above tweak will forcibly shut the system down and then force the device to restart.
Meanwhile, if you’re using a Mac with a removable battery, a power cycle is done this way:
Unplug your Mac from the power source.
While it’s unplugged, remove the battery from your Mac then wait for about 30 seconds.
After the elapsed time, reinsert the battery.
Then power it back on.
This method is also applicable to a Mac desktop such as Mac Pro, Mac Mini and iMac.
Most of the time, performing this tweak yields a positive outcome and therefore gets your Mac to restart normally unless it runs out of power or hardware damage is present.
Third solution: Reset System Management Controller (SMC) on your Mac.
This method is only applicable on Mac computers with the T2 chip. To find out if your Mac has a T2 security chip, you can view the System information from the Apple menu.
The SMC is a chip installed on the logic board. It’s designed to control all power functions like telling the computer when to turn on. If by any chance, the SMC gets corrupted and failed to work as intended, resetting it can help. So here’s what you can try next:
Simultaneously press and hold the Control, Option (Alt) and Shift keys on the keyboard for about 7 seconds.
After 7 seconds, press and hold the Power button.
As you hold these keys, your Mac will turn off (if it’s turned on).
Keep holding all four keys for another 7 seconds and then release them all.
Wait for a few more seconds and then press the Power button to turn your Mac on.
Is your Macbook still not turning on?
If nothing else worked and you still couldn’t get your Macbook to power on, it’s time to rule out hardware-related issues.
If you’ve recently installed a memory card or external drive like SSD on your Mac and then suddenly it doesn’t power on, what you’re dealing is more likely a startup issue due to a corrupted or incompatible external drive.
To rule this out, remove any SSD or memory card from your Macbook and then try to see if it’s able to start up or restart normally.
If nothing else works, then opting for service can be considered among the last options.
