Today, one of our customer brought in a Macbook Pro A1278 model.

The customer told us that she did not really use this macbook that much, but one day, it started to turn off itself during booting.

We powered it up, and we saw the apple logo with a loading bar (indicator), then it turned it off itself without any beep sound or any warning messages.

First, we though it could be the Macbook battery, but the battery was fully charged, and it was okay.

So we did a research on Google It looks like so many people with Macbook have the same problem like our customer.

This means, we will need to repair the corrupted system files, or maybe we can format the existing hard drive, then install Mac OS again, or when there are physical damages to the actual hard drive, we will need to replace the existing hard drive.

Anyways, here is what to do when your Macbook turns off itself during booting.

Press and hold Command R keys at the same time, and hold it until your Macbook triggers the Mac OS X Utilities.

Once you click it, the first thing you need to do is to select the right disk or partition on the left side menu.

If there are problems detected, you can click Repair Disk button to repair any existing errors on the selected hard disk.

You can open OS X Utilities again, and click Re-install OS X.

This built-in OS X installation app will download the right OS X operating system, and therefore, you dont need a Macbook OS X disk for it.

Depends on your internet speed, the estimated time of installation varies.

Always, plug the power cord to void your Macbook being shutdown due to a low battery during the installation process.

If you need to backup, you need to remove the hard drive from your Macbook, and you need to transfer files to a USB or an external hard drive.

Depends on your Macbook model, disassembly method varies, but typically by removing the bottom plate will give you the access to your hard drive.

Make sure about the size of your hard drive (like 500GB, 1TB) and buy the right size for you.

Always remove the battery connector first, and remove the hard drive connector.

After putting a new hard drive, you can re-install Mac OS X.
