If you’ve turned on your MacBook only to have it sit there with a blank screen, don’t panic! This article will walk you through a few different troubleshooting steps so that you can get your computer up and running again in no time.
Check the power connection
If your MacBook won’t boot up, the first thing you should check is the power connection. Make sure the power cord is plugged in securely and that the outlet you’re using is working. If you’re using a battery pack, make sure it’s charged.
If none of that works, try resetting the SMC (System Management Controller). To do that, shut down your MacBook and unplug the power cord. Wait 15 seconds, then plug the power cord back in and wait another 5 seconds. Press the power button to turn on your MacBook.
Check if your MacBook is on
If your MacBook won’t boot up, the first thing you should check is whether or not it’s turned on. It sounds like a silly thing to check, but sometimes people accidentally leave their laptops off or in sleep mode when they’re trying to use them.
To turn on your MacBook, simply press the power button. If it’s already on and you’re having trouble getting it to boot up, try holding down the power button for a few seconds to force a restart.
Once your MacBook is on, try pressing the keys on the keyboard or moving the trackpad to see if it wakes up from sleep mode. If it doesn’t, you may need to troubleshoot further to figure out why it’s not booting up properly.
Try an SMC reset
If your MacBook still won’t start up, you may need to try an SMC reset. This will reset the System Management Controller on your MacBook, which is responsible for a variety of low-level functions. To do an SMC reset:
1. Shut down your MacBook.
2. Press and hold the left Shift key, the left Option key, and the left Control key on your keyboard.
3. While still holding those keys, press and hold the power button for 10 seconds.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on your MacBook.
After doing an SMC reset, try starting up your MacBook again and see if it works. If it still doesn’t work, you may need to take it to an authorized Apple service provider for further diagnosis and repair.
Check your hard drive
If your MacBook won’t boot up, the first thing you should check is your hard drive. If your hard drive is corrupted or damaged, it can prevent your MacBook from booting up properly. To check your hard drive, open Disk Utility and select your hard drive. If you see any errors, you may need to repair or replace your hard drive.
If your hard drive is healthy, the next thing to check is your computer’s memory (RAM). If you have a bad RAM chip, it can cause your MacBook to freeze or crash. To check your RAM, open Apple Diagnostics or Apple Hardware Test and follow the instructions.
If all else fails, you may need to reinstall macOS. This will erase everything on your hard drive, so be sure to back up your data first. To reinstall macOS, open the Recovery partition and follow the instructions.
Reinstall macOS
If your MacBook won’t boot up, one possible solution is to reinstall macOS. This will erase all of the data on your MacBook, so be sure to back up your files before proceeding. To reinstall macOS, follow these steps:
1. Shut down your MacBook.
2. Press and hold the Command and R keys while you turn on your MacBook. Keep holding the keys until you see the Apple logo or a spinning globe.
3. Select Reinstall macOS from the utility window that appears.
4. Click Continue and follow the instructions to install macOS.
Get more help from Apple
If your MacBook still won’t boot up after following the troubleshooting steps above, you can get more help from Apple. You can schedule a Genius Bar appointment at an Apple Store, or contact Apple Support online or by phone.
When you contact Apple Support, be sure to have your MacBook’s serial number handy. This will help the support team determine which service and support options are available to you.
Conclusion
If your MacBook won’t boot up, don’t panic. There are a few things you can try to get it up and running again. First, try resetting the PRAM. If that doesn’t work, you can try resetting the SMC. If neither of those options works, you may need to take your MacBook to an Apple Store or authorized service provider for further diagnosis and repair.
