Nothing happens when a
charger is connected to the
phone
The voltage at R210 towards
R209 > 0,4V
Replace CCONT (N201)
¦1RW &KDUJLQJ§ PHVVDJH
"Not charging" message
appears in the display
The voltage at R220 towards
C236 (BSI, N201) = 0,8V when a
charger is connected.
The voltage at R220 towards
C236 (BTEMP, N201) = 0,5V
when a charger is connected.
When the battery is an NI
battery, then the voltage at R208
towards R200 must be app. Vb-
200 mV. When the battery is a LI
battery, the voltage at R208
towards R200 must be Vb
The voltage at R208 towards
R200 and CHAPS (N200) rises
slowly when a charger is
connected.
J201 performs as follows :
Li battery :
0 -> Vmax-200mV
PWM high ("1", 2,8V)
Vmax-200mV -> Vmax
PWM = 1 Hz
Ni battery :
PWM = 1 Hz
