X101, X102 Battery connector, X200 system connector
- Check soldering of connectors.
- Check mechanical appearance of connectors, change if necessary.
F101 faulty
- Check resistance of F101 (0 Ohm)
V_In line short circuit to GND
- Check resistance of V_In line to GND (~50 kOhm).
- if resistance is not ok Check R101 / C101 / C144 or change N101.
N100 faulty
- Change CCONT / N100 if any A/D value is out of limits but DC voltage is ok.
- If DC voltages are not ok Check corresponding voltage dividers and battery connectors X101/102.
- Probably broken solderings under CCONT / N100. Remove CCONT, tinplate oxidized pads carefully with flux
and solder, replace sparepart with µBGA rework machine.
Energy management calibration
- Run calibration if charging stops too early.
- If message “not charging“ appears on LCD.
- If any part in the charging circuit has been replaced.
