Chapter 3: Charging not possible

Pre-check
The first thing to do if charging the battery fails is to check whether charging is not possible only
occasionally or if it does not work permanently. If the fault appears from time to time only, follow
the repair instructions:
If charging permanently does not work, run energy management calibration. In case EMC works
properly, try to charge after calibration; in case of any failure message follow the repair

Mechanical faults
In case charging is not possible only from time to time, especially check spring contacts of charger
plug I215 if bent, soiled or corroded. Furthermore, make sure that contact pads for connector on
PWB are clean; if necessary clean them with an appropriate amount of alcohol. In no way use any
scratching or rubbing tools!
Electrical faults
The most common fault, if energy management calibration does not work, is a defect fuse F130.
Check that resistance of fuse is zero ohm; replace part if necessary.
To ensure the correct functioning of phone, run energy management calibration whenever having
changed a part in the charging circuit, or when the flash circuit containing the tuning values has
been exchanged!
