MacBook Pro suddenly dead and does not turn on

A month back it started giving me the problem of booting up. I saw your link and it helped me. Now again i am having problem of boot. Tried all the functions.

I discovered it wouldn't turn on even after many trials to get it to start. I left it for some time and came back to it but still had the same issue. Its working fine now and I appreciate that your site could help. Thank you so much. Mid MacBook suffered what seemed to be a too fast battery discharge on normal usage.

Changed for another new battery, seemed to have greater capacity according to System Parameters software and much greater discharge time.

What to Do When Your Mac Won’t Start Up

When it is switched on the screen awakens, the Apple logo appears, the progress bar starts, very very very slowly proceeds but that is as far as we get. No further. You might consider reinstalling the operating system. That should provide a boot up menu either from your computer HD or another HD that you use as a backup. Options should include restoring a prior backup or reinstalling the operating system. Some of these options may delete personal files so use at your own risk. Thank you so much for your website! Awesome stuff! Your instructions were really instructive and clear.

Check the Hardware

I turn off myMacBook Pro and when I turn back on, I get the apple with black line inching its way to the end. Gets to the end and does nothing. I ran the hardware diagnostics and it said No Problem found. Me too. Disk First Aid showed my hard drive as being completely full.

Unplug the battery. Unplug the MagSafe power cable. In some cases, you may need to reset the system management controller SMC firmware on your Mac. On current MacBooks without a removable battery, plug in the power cable. Release all four buttons at the same time, and then press the Power button to turn the Mac on. On MacBooks with a removable battery, unplug the Mac from its power source and remove the battery. Press the Power button and hold it down for five seconds. Release the Power button, reinsert the battery, plug in the Mac, and press the Power button to turn it back on.

Plug it back in, wait five more seconds, and then press the Power button to turn the Mac back on.

To access recovery mode, boot your Mac up. You should try to press these immediately after you hear the chime sound.
