What does Q1403 do?
okay I got a 6 that had water damage, removed shorted caps etc. Board looks very good, but it is missing Q1403. When plugged in, the cpu heats up a bit but that's it. I was thinking q1403 reported the battery voltage, and if its not there it would probably show 0% but I could be totally wrong. Could I get this board to fire up without it? I tried to source this ic from another board but I was taking it off a board and then dropped the ic on a carpet floor, then I ran out of donor boards. anywahy, what does it do and can it work without it?
Is this a good question?
