How to repair a Mac that won't turn on

If You Don't Get Answers (including regular Apple clock or fan sounds ), here are a few things that can keep your Mac on:
. Check the charger
It is always a good idea to check that your charging cable is connected to both the power source and the computer.
In that case, check that the cable itself is intact or if there are exposed wires or tears. They may be your culprit.
It is also a good idea to try moving to another outlet (or connecting to another device in the same outlet) to see if the outlet works, as well as replacing the charger or adapter.
2. Make a Power Cycle
A power cycle is essentially a forced restart.
To do this on a MacBook laptop, hold down the power button for about 10 seconds. For desktop Macs, disconnect your computer for 10 seconds, then plug it in again.
If you can hear that your Mac does sound but still can't turn it on completely, here are a few ways to help you solve your problem:
1. Check a Display Problem
If you are using a separate monitor with your Mac, try extracting the video cable and reconnecting it. And, again, make sure all your cables are properly connected to both the power source and your Mac is always a good idea.
Another thing to check is the brightness settings – your brightness can be so low that it makes the screen look like it is off. Press and hold the higher brightness indicator (F2) to see if that is the problem.
2. Starting in safe mode
Press the power button while holding down the "Shift" key. Release the "Shift" key when you see the login screen. If your Mac starts, be aware that your interface may look different than normal.
From that time on, You can do some more troubleshooting to get the root cause of your issues. These may include: Running a scan for viruses, checking the file system, and resetting the parameter frame or PRAM.

- Get help online (via Apple support).
