What to do if your MacBook Pro won’t turn on

Nothing causes that sinking feeling like when you boot up your MacBook Pro, and nothing happens. It will usually happen when you have a lot to study, a deadline is approaching, or send an important email. Aren’t those scenarios when things like this happen? Of course they are.

Apple devices are known to be very reliable (reasonably, but their intentional designs such as keyboards and others, depending on the model / release, ensure less longevity, so you are forced to buy a new one, but we are not going there in this article. ). No matter the reputation, all devices have problems at one point or another.

This guide assumes that you have not made any recent changes to your MacBook Pro, such as adding or replacing RAM or making any significant hardware modifications. For macOS laptops, here’s what to do if your MacBook Pro won’t turn on.

1. Check the black or white screen

When you initially tried to turn on your MacBook Pro, did it not turn on at all or did the screen remain black?

A black screen is a common problem for laptops and is not limited to Apple. Before doing anything else, first make sure you haven’t accidentally set the brightness to zero.

There are two keys at the top of the keyboard that have sun icons. One is to darken the screen and the other is to brighten it. Although most laptops will not go black with this setting, it has yet to be confirmed. If the brightness does not affect the black screen, continue. Turn off the laptop, remove any connected peripherals, and then turn it back on while listening carefully.

Do you hear any buzzing? Any beep? Fan noises? If you hear something but see nothing, it may be the screen and not the laptop. If you don’t hear anything, you need to fix the problem further.

2. Boot into recovery mode

If you hear noises and receive feedback while performing actions, but the screen is black, you can try starting your MacBook in recovery mode to repair any issues you are having. To start recovery mode, press and hold the power button. If this action works, you should see the macOS utility screen.

If recovery mode was successful, restart your Macbook and it should start normally. If not, keep reading; there may be other problems.

3. Check electrical connections

Connect your MacBook Pro charger to the laptop and to the wall socket. Check that both connections are tight. Make sure the power cord is not damaged. If nothing happens, try a different wall socket or check the one you are using with a different device.

If the outlet works, check the power cord or adapter. If you are lucky enough to have a replacement of any of them, give them a try. If you can borrow a spare for five minutes, please do so. But first, promise not to break it because it is worth its weight in gold. If the laptop still won’t work with a different charger, continue with troubleshooting.

Note: The charger used must match the OEM charger specifications for your specific model. There are at least a couple of different chargers. For example, the mid-2015 MacBook Pro uses an 85-watt charger.

Make sure you are using Apple brand cables if possible. Some third-party charging cables do not have the correct amperage required to properly power your device, or the cables are fragile on the inside and could be damaged. Using the cable and charging block that came with your device can be the trick to turning on your computer.

4. Power cycle

The next step is to perform a complete power cycle of your MacBook Pro. Although it sounds complicated, it is very simple.

All you need to do is hold down the power button for a minimum of ten seconds. This action cuts all power to the laptop and is equivalent to removing the battery. You may hear a noise when doing this.

Once you’ve held down the power button and then released it, leave it off for a few seconds and then press it again to start the MacBook Pro normally. If you are lucky, it will start up successfully. Otherwise, the MacBook Pro will still not start and you will need to read on.

5. Restart the SMC

The SMC is the system management controller. It manages all the low-level functions of the Macbook Pro, such as the power button, display, battery, fans, motion detection, keyboard, indicator lights, and the like. Resetting the SMC is usually left for last as it resets many settings to their default values. If you’ve made it this far without a successful boot, try resetting the SMC on your MacBook Pro.

  1. Unplug the laptop from the charger and peripherals.
  2. Hold Shift + Control + Option and the can button for ten seconds.
  3. Release all keys and reconnect charger.
  4. Then press the postwis to start your laptop.

If an SMC error was causing the MacBook Pro to not start, it should now start normally. You’ll have to reconfigure some hardware settings once it boots up successfully, but it’s a small price to pay to get your laptop working again. This setback is undoubtedly better than professional maintenance that takes time and costs money.

6. Remove the battery

If you are using an older MacBook Pro, it may have a removable battery. Check below to see if the battery is removable or not. You should see a small locking clip next to the battery if it comes out. To remove the battery, do the following:

  1. Undo the locking clip underneath your MacBook Pro.
  2. Lift the plastic flap to expose the battery.
  3. Pull the small tab to release the battery and remove it.
  4. Reverse the process to reinsert or replace the battery, or replace the flap and clip.

A newer MacBook Pro will not have a removable battery, so this procedure will not be relevant to you if you have one.

7. Unplug your accessories

It might sound strange, but if your MacBook is having trouble starting up properly, it’s worth trying to start it up with everything unplugged.

All USB devices, printers, or other connections should be temporarily disconnected. Once done, try restarting your MacBook by pressing and holding the power button.

If your MacBook Pro still won’t turn on, there is very little you can do at this time without voiding your warranty. It may be better to find the closest one apple store and let one of the technicians take a look at it. Hopefully what you can accomplish is get your laptop working again without affecting the warranty or potentially making things worse.

Additional problems

As mentioned by some in the comments, if your MacBook turns on but doesn’t show up, you most likely have a display cable, display, or graphics card problem.

If the reinstallation process of your operating system was interrupted, then your problem could be with a damaged or now non-existent critical system file. You’ll want to retry the reinstallation process using a flash drive or network installation.

Turning on MacBooks

Given its cost, it’s always a hassle when a MacBook won’t turn on. If this happens to you, follow the steps above or take it to a reputable repair shop or Apple Store if it is still under warranty.
