Ever skipped a heartbeat if your precious MacBook doesn’t respond to the power on key? The next eight steps may help you breathe a sigh of relief. If you have a MacBook Air, a MacBook Pro, or even an iMac, these troubleshooting tips may assist in getting you out of an annoying situation.

1. Check the Power Supply: Ensure your Mac has enough power to start up, press the Power button and look for typical signs like the starting up sound, the lighting of the Apple logo on the screen or the back, press the caps lock key to check if the green light indicator works. When none of these work, there’s a probability that the battery has drained. Put it for a charge for a few minutes then try again. If none of these work, move on to the next step.
2. Check for hardware issues: Start with the power cord, check if the power socket and cable aren’t damaged. Make sure your electric outlet supply is alright. Sometimes, it may take up to five minutes for the battery to power up, wait and watch if your MacBook comes to life. You may have upgraded the RAM or hard drive that isn’t compatible with Apple, try reinstalling the old hardware to power up.
3. A force restarts: Press and hold the power button for 10 seconds then release it then restart the computer as usual. Often, a frozen MacBook issue may be resolved with a force restart.
4. Reset SMC firmware: Resetting System Management Controller can work, Shut Down the computer, Disconnect everything apart from the Power Cable. When the computer is turned off press and hold, control, option, command, and the power button for four seconds release them together and restart the Mac as usual. SMC resetting procedure depends on your MacBook variant click https://support.apple.com/en-us/HT201295 for more information.
5. Recovery mode: There’s a possibility that an issue with the hard drive could affect starting up the Mac. Try rebooting in recovery mode. Restart your Mac after the welcome chime press and hold Command and R keys. macOS utility window should pop up, from the drop-down menu select Disk Utility, select the name of your hard drive and click First Aid or Run. Wait until the scan is finished and restart your computer. If you are still having trouble, try the next step.
6. Reset Non-Volatile Random Access Memory: The NVRAM is responsible for a variety of functions, if you are having trouble with the speaker volume, screen resolution, or startup disk then a reset can solve them. Restart your machine then press and hold the Command, Option, P, and R keys at the same time until the grey screen appears. Hold down these keys and release the Apple logo and welcome notification chimes. This didn’t work, move on to the next step.
7. Boot up in Safe Mode: Press the Power button and hold the Shift key until the login screen appears. Click the Apple logo at the upper left-hand corner and select restart if none of these work you may have to resort to the last option.
8. Reinstall macOS: Here’s the last thing to try before heading to an Apple Authorised Service Centre. This will work out if you were able to start your Mac in recovery mode. Select Reinstall macOS from the macOS utility menu and follow the instructions.

Most of the time, these steps may work but if not you will have to visit a Service Centre if your Mac fails to start. I hope this could help you and remove the annoyance of not getting your device started.
