When you buy a new MacBook, you have a deep belief it will run smoothly for ages. But you forget that even though MacBook is a high-end product, it is still a machine and can experience performance-related issues. For instance, it may start slowing down. In this case, you can clean startup disk on MacBook Air or any other MacBook to get things done. However, if your Mac doesn’t turn on, you are dealing with a kind of more serious problem. And in this post, we’ll tell you what to do if your MacBook won’t turn on.
Before We Start, Let’s Figure Out This
There is a huge difference between Mac’s refusal to start up and its refusal to turn on. To check it out, do this:
Hit the power button on your Mac and see what will happen. If there is no startup chime, drive or sound noise, and no visual materials appear, then your Mac doesn’t turn on at all. If it’s so, keep reading this post to figure out what has happened and how to fix it.
Step 1: Check Power Connection and Examine Carefully the Charger’s Cable
Yes, yes. Don’t forget to do it before you move on. In many situations, checking power connection or the charger’s cable helps to troubleshoot not-turning-on Mac. Just make sure you have done this:
- Check whether the Mac is plugged in and the power is on. If it hasn’t been plugged in, change it and give your Mac time to get charged.
- Make sure your battery isn’t dead (for instance, if you have an old mac, it might need to be replaced).
- Examine the entire cable along its length to make sure it isn’t damaged.
- Try another charger and see how it impacts your Mac’s work.
Step 2: Unplug All Accessories and See What Will Happen
Printers, USB hubs, mouse, or speakers could be the reason why your Mac isn’t turning on. Unplug all accessories and see if it helps. Also, if you have recently upgraded memory or bought a new hard drive, make sure it is installed properly and is compatible with your Mac. If you can, reinstall the old hard drive or memory and see whether it has helped. If nothing helps, go on reading.
Step 3: Perform a Power Cycle
If the previous steps haven’t worked, try to reboot your Mac in a power cycle mode. To do it, follow these steps:
- Unplug your Mac (remove the power cable).
- Hold down the Power button and wait for about 10 seconds.
- Still holding the Power button, plug in the power cable.
- Wait 10 seconds again.
- Let go of the Power button and start Mac’s performance in a normal
If it didn’t help, move to the next step.
Step 4: Check Your Display’s Work
If you use a desktop Mac, the problem might lie in a non-working display rather than in the Mac itself. Listen to your Mac very carefully. If it makes any sounds while booting up, it has display-related issues. Your Mac might not turn on because it cannot access the display. If it’s so, you are dealing with display hardware problems rather than with broad startup issues. To troubleshoot problems with monitor, try this:
- Check the power supply to both – your Mac and the monitor (if you use a separate unit).
- Make sure all cables are connected properly.
- Check whether your monitor is compatible with the Mac.
- Remove all switchers and extenders as well other devices between your Mac and the monitor.
- Remove the video cable and plug it in again.
- In case there are no than one monitor in a daisy chain, disconnect them and try to use just one.
- Try different adapter or display (for instance, try DVI instead of VGA).
- If possible, try to use a different display, or a different adapter (use DVI instead of VGA, for example).
- Apple then advises users to try resetting the PRAM or starting up in Safe Mode and adjusting the resolution in System Preferences. (Both of these steps are covered further down in this article.)
If after all these tries, your Mac won’t turn on, it’s better to get professional assistance in one of the service centers.
