19 Sep What should I do if my MacBook Pro won’t turn on?
When you press the Power button or Touch ID button on your Mac, if you don’t see any images, video, or visuals of any sort on your display, if you don’t hear a startup chime, and if you don’t hear any fan or spinning drive noise, then most likely your MacBook is not turning on. When your MacBook Air or MacBook Pro won’t turn on, it’s very rare that the problem is with the whole setup — more likely one of the components is misbehaving, which can range from your display to software glitches.
The first step is to check, as obvious as it sounds, make sure that your Mac has any battery life left. Try unplugging and plugging your Mac back in. Once you know your Mac is powered properly, try turning it on by pressing the power button.
If your Mac won’t boot at all, it might be something to do with hardware.
In both cases, when your MacBook Pro or MacBook Air won’t turn on, make sure to disconnect all keyboards, mice, external HDs, and so on to make sure they are not part of the problem. If nothing has changed, you need to do a power cycle.
To do a power cycle:
- Shut down your Mac by pressing the power button (keep pressing)
- Unplug all the power cables
- Hold the power button for 10 more seconds
- Restart the Mac as usual
Hopefully, the Mac won’t turn on. The issue is now fixed. If not then follow the below methods to fix it:
- Restart Mac in safe mode:
If you’re still experiencing problems, it’s possible to restart the MacBook in safe mode to bypass lots of small processes that might sidetrack your Mac from working properly.
Entering safe mode is easy:
- Turn off your Mac.
- Power it back on while holding Shift.
- Release Shift when you see a login menu.
Now that you know the situation with your Mac is not hopeless, you’re getting closer to the finish line. Sometimes, you just need to restart the MacBook once more for everything to work smoothly.

- Reset your Mac’s NVRAM:
Even when your Mac is turned off, there’s a special kind of memory that’s keeping tabs. It’s called non-volatile random-access memory (NVRAM) and in very rare cases can lead to problems booting up. But if you’ve already tried all the tips above, it could be a very rare case indeed.
To reset NVRAM:
- Turn off your Mac.
- Hold ⌘ + Option + P + R and turn on your Mac.
- Release the keys when you hear the second startup chime.
- Reset the SMC:
Another vital operator in your Mac’s ecosystem is the System Management Controller (SMC). It handles keyboard backlighting, responds to you pressing the power button, manages your battery, etc.
Resetting the SMC is essentially the last thing you can do before you completely reinstall the macOS:
- If you’ve got a MacBook, press Shift + Control + Option and power up.
- For iMacs, simply unplug the cable for 15 seconds, plug it back in, wait five more seconds, and then power up.
