An Apple Mac that doesn’t power on could be a result of several different factors. It is often difficult to identify the exact root cause, in which case you’ll need to speak to an Apple specialist.
What are the common signs of a Mac that’s not turning on?
- Mac doesn’t turn on.
- Mac turns on but the screen remains black.
- Mac starts then halfway through the booting up process turns off.
- Mac stops charging.
- You can hear parts moving inside the Mac but the screen remains off.
What should you do if your Mac is not turning on?
If you have a MacBookPro, MacBook Air or MacBook that’s not turning on try:
- Disconnect your charger cable and check whether the charging indicator is showing a green or orange sign. If the sign is green and the Mac doesn’t turn on then it might be a charger issue. Try another charger.
- If the next charger doesn’t work try another power adaptor and test with both chargers this time to make sure there is power going to both.
- Try and reset the SMC and PRAM. Check out ZA Support’s simple SMC and PRAM reset guide on YouTube how to reset the PRAM and SMC on your Mac.
- If this still doesn’t work and you have a Mac where the Apple RAM can be removed try and remove it and see whether the Mac turns on. WARNING removing RAM can cause damage to the Mac if not done properly. If you are not an Apple professional please be careful.
- At this point, there could be multiple factors causing the Mac to not power on.
