2 without chime, fan start to spin automatically, no display
Hey guys, my friends just gave me this macbook pro, when i plug in the charger, fan automatically start spinning slowly, no chime, i havnt even tapped the power button, and when i try to shut it down by pressing the power button for 10 seconds, its dosent turn off (fan still keep spinning)
Only way i could get a response from the macbook pro, is if i press the power button (located at the keyboard) and THEN plug in the magsafe 2, and keep pressing the power button, after about 5 seconds fan start spinning extremely fast and theres a chime, then the apple logo and everything works as normal, except for the fans, they’re extremely fast and noisy…tried resetting SMC, PRAM already to no avail…
problem number 1: need to do the aforementioned method to start up my mac
problem number 2: even after it turns on, the fans are too terribly fast and noisy
one odd thing to notice is, when i unplug the battery, and plug the magsafe 2, fans dont spin at all, and if i press the power button, i get no response from it as well…
what could be the problem?, anything software?, tried completely new macos re-install, still the same!
Это хороший вопрос?
