After replaced pro 4 LCD,won't turn on on battery mode unless plug it
After i replaced pro 4 LCD , won't turn on on battery mode unless plug it.
Before i take off the broken screen the pro was working good only screen was broken, so i shutted down and start working on it , after i take off the old screen i tried to connect the new screen on to try it but no response at all.
it does only work when i plug it by the charger and it does shows me that the battery is 100% full on the screen ?
and also i did put piece of paper between the connects part for the battery and motherboard and it does shows me X on the battery on the screen when i turn it on
but i couldn't solve the problem since 1 week and i'v been searching online but no one had these issue before .
so how can ifixit ??
