It’s unusual however you may find yourself in a circumstance where your Mac won’t startup. There are several reasons it won’t turn on, but you probably simply wish to get it up and running again as quickly as possible. There are some different checks and changes that you can quickly use to troubleshoot the concern.
Does Your Mac Switch on?
The very first obvious thing you require to examine –– does your Mac not switch on or not launch? These are two totally different things.

Another repair is to try various power cable or adapter. If you plug in the adapter and your Mac doesn’t chime or the charging light doesn’t turn on, the power adapter might be the concern.
