Can anyone help?
I have 2 old nokia 5110 and neither will charge? I have tried 3 different chargers and 4 different batteries but none of them will charge. Not sure what the circuit boards look like when they are normal but am not afraid of a little tinkering if there is a solder I can refresh or any signs of issues or a way to test the batteries without the phones I would be greatful.
Unfortunately upon this manufacturer's sponsored forum we are prohibited from discussing disassembly of devices or posting schematics, which may in part be a reason for your post eliciting zero response. I know with my old 3310 if battery allowed to completely run down it can take some minutes before any sign of life show up!
