My MacBook would turn on some days, wouldn't on another!
I purchased my MacBook pro 13" in July 2015, and just after the one year warranty,this incident happened. I had kept the MacBook for charging as only 4% battery was remaining. I switched off charging once it had remained there for about 20-25 minutes, as sometimes it happened that the indicator would be orange and it would keep showing battery 99% until u remove the plug.
I tried to start the machine the next day, I heard the start-up chime and saw the progress bar, but hardly after 10-15%, the screen went blank. I tried that 2-3 times, with the same result. I took it to a local MacBook repair shop where he opened the machine in front of me. The guy told me that the GPU of the device is dead. He showed me that the fan is starting and stopping intermittently. I got the machine back.
Next, I took it to apple service centre, where the machine started normally. The person did a PRAM reset. I brought the device back and restarted it. The date was reset to January 1, 2015. I tried resetting the date, with no luck. The option to manually reset was greyed out, and the automatic date was wrong.
The next day, when I started the machine, the date was also correct. I took the back-up and closed it.
The next day, it did not turn on. And today, it turned on normally. I did the hardware test, and it did not find any error.
Anybody has experienced such a thing earlier, or can suggest what could be possibly wrong?
Update: downloaded coconut battery and the screenshot of battery details is here.

Is this a good question?
