Won’t turn on
Brought a new battery from here about a month ago for my MacBook Pro 15” retina late 2013-mid 2014 installed it and it all work fine almost like new.
Then today I went to turn it on and nothing it’s just a black screen when trying to turn it on and no sound just nothing. It’s been fine leading up to this so was very confused as to why it wouldn’t start. It was fully charged the last time I used it and when I plugged the charger in it showed as green.
I tried holding down the power button didn’t work I tried a forced restart still nothing although after doing this the light on the charger went from green to amber and has stayed amber.
I opened up the back and all looked fine from appearance although I don’t know much about the inside of these things. I unplugged the new battery and plugged it back in and retried both start up methods still nothing. I then found on line someone said to unplug the battery and plug in just the charger which then gave off a light ringing noise first sounds of possible life. Tried both start up methods again still nothing. Any suggestion On what this could be or other methods to try before paying to have it looked at or if it is even worth getting it looked at.
