Hi my macbook pro is very slow charging (about 10 hourse!) there is (sometimes) horizontal line at start up (I repeat only sometimes) I changed charger and battery but it doesn’t solved is this from logic board? please help Best Regards!
The next step in the troubleshooting process would be to try and replace the magsafe port, if you indeed know its not the physical charger itself. This sits between your logic board and charger. If you are noticing slow charges and have eliminated the possibility of having a bad charger, it’s possible your magsafe port is showing signs of its age. If I am not mistaken this is the part you should be looking for. iFixit Guide Edit = Repair Guide Link
Take it in to an ASP and have it tested for this issue: MacBook Pro Repair Extension Program for Video Issues https://www.apple.com/support/macbookpro…
Ordered one and will have at it this weekend. Hopefully this is the fix.
