Hey there. I recently bought a Macbook Pro 15” 2010. When i got it the battery was a little “exploded" so i had to take it out. It acts kinda strange. Because when i plug it in to the magsafe charger the light is there but won’t turn on for some reason. But if i hold the power button for 10 seconds and then plug in the charger (while still holding the button) for about 5 seconds, it turns on and boots up to high sierra. The keyboard backlight dosen't light up and the fans are spinning as fast as it can go. And when i turn it off again but still have the magsafe charger in, it could boot up just fine with one click on the power button. When i take out the charger and put it in again i would have to do the whole thing again with holding the power button etc. Do any of you guys have any idea what it could be?
