Q: Fan running on MacBook Pro and draining battery

Hi,

I have a MacBook Pro (Retina, 13-inch, Late 2013) running OS X 10.10.5 and since yesterday the fan started running fast and draining battery life considerably. I do not recall adding any new software or changing anything really.

Nothing is running now except Safari and even if it is off the battery starts running fast only a minute after starting the machine and will only stop when i shut down.

When I switch on and leave the laptop on just the login screen without logging in to any user it just takes a minute for the fan to start running fast. I fully charged the laptop and left it for 4 hours and then i switched on and it took just 5 minutes for the battery to start running fast again. The bottom part next to the screen is getting hot though.

I tried the SMC (i guess) reset with the left Shift+Crt+Alt+Power, but it did not solve the problem.

Any help please?

Thank you

MacBook Pro with Retina display, OS X Yosemite (10.10)

Thank you Ogelthorpe,
As I was setting up to run the apple diagnostics, I just realised the fan is not over running anymore. I am not sure wether it stopped when I turned off the wifi reception to put an ethernet cable (via USB) or it was already normal before. I did not do the diagnose and turned on the wifi and so far so good.
I will leave as it is and if it happens again I will do the diagnose. Either way I will update the post tomorrow if all still good.
Thank you for the support.
Cheers
