iPad Pro Power Issues After Screen Replacement
I have an iPad Pro 9.7 that a customer brought in with a broken LCD/Digitizer. The tablet still worked from what we remember. We disassembled the tablet and removed the broken LCD/Digitizer. Of course, we put a guitar pick in-between the battery and the motherboard as we normally do before disconnecting the old screen and connecting the new LCD/Digitizer (got part from Mobile Defenders). The new LCD/Digitizer works perfect so we transferred the home button and sealed back up the tablet. We tested it shortly, but apparently did not catch the fact that the battery is now having issues.
Customer brought it back due to boot loop issues. The battery percentage will go anywhere from 1%-4%, or as high as 11%, but no more. I have disassembled it down to the motherboard, clean the connections underneath and on the battery with no change. I also have removed the battery and replaced it, but the new battery has the same result. In fact, I let the new battery drain all the way down, and now with the new battery the iPad gets stuck in a boot loop. It does not charge the battery at all, for as soon as I unplug the iPad, it turns off. I put the old battery back in and can get it to turn on again. When you plug a cable in the charging port, it DOES turn on the tablet and it DOES show charging, though sometimes I have to unplug and plug it back in for it to show the charging symbol. Suggestions?
