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.
