Panic on board: you press the button, the Apple doesn't turn on, the screen remains desperately black. Your heart races, your files may be trapped, and you're already imagining the hefty bill to replace everything. But before you panic or rush out to buy a brand new Mac, know that there are much more economical solutions.
In many cases, a Mac that refuses to boot isn't necessarily doomed. A simple diagnosis, a targeted repair, and you're good to go.
Common causes of a Mac that won't turn on
If your Mac stops showing any signs of life, there's no need to assume the worst right away. Here's three common causes, often more banal than we think.
A tired battery
This is one of the most common problems. Over time, the battery wears out, loses capacity, and eventually fails. A simple Apple battery replacement may be enough to bring your device back to life, without having to buy a new one.
A power problem
Before blaming your Mac, consider checking your charger and cables. A loose connection, a damaged plug, or a faulty adapter can all be enough to prevent it from booting.
A faulty internal component
Motherboard, hard drive, keyboard... Sometimes, an internal component decides to go on strike. The good news is that it can be repaired. And it's much less expensive than a new computer.
Going through an independent repairer: a smart choice
