Power and charging troubleshooting

Phone is dead

The phone does not use any current at all when the supply is connected and/or power key is pressed. It is

assumed that the voltage supplied is 3.9 VDC. UEMEK will prevent any functionality at battery/supply levels below

2.9 VDC and the software will shut the phone down at 3.1 VDC.
