Solutions For Macbook Not Turning On
When your MacBook Air or MacBook Pro won’t turn on, it’s very rare that the problem is with the whole setup — more likely one of the components is misbehaving, which can range from your display to software glitches. Our task here is to isolate this problem to solve it.
The First Step To Check Battery Life
The first step is to check, as obvious as it sounds, whether your Mac has any battery life left (or in the case of iMacs whether the cable is connected correctly). Try unplugging and plugging your Mac back in. If you have an older MacBook , your MagSafe cable will show you a green light if the computer is charged and amber if it’s still charging.
Use Only Apple-Made Cables
As a rule, try to only use Apple-made cables. Even though they could be more expensive (check eBay or Craigslist for secondhand ones), they are more likely to be safe for your Mac and not put extra strain on your Laptop battery life. Also, don’t forget to test your outlet — it might just be that you’re using a faulty one.
