Member: 12837 Status: Offline Thanks Meter: 2,740 | Battery status unknow... Hi2all The problem occurrence while phone can't read battery ID resistor... Possible cause is a: bad battery ID resistor (change batt!); bad wireing between batt connector and ASIC chip - for 9xx chip is SAGEM 18599662-5 ( check wires and resolder all connected components); bad ASIC chip ( change/resolder ASIC); Bad PCB - destroyed or some deformation(no solution!); |

Member: 22505 Status: Offline Thanks Meter: 0 | Problem solved. (At Mx9xx. But i think at other models not big difference) Battery Pin-out: 1- +Vbatt 2- -Vbatt (Gnd) 3- Indicator battery type 4- At board must be closed to GND Beetwen pin 3 and 4 at battery set resistor. Resistance - battery type . I have two type - 7k5 and 13k. At board set capasitor. Pin 3 through fuse or resistor (0 ohm) (white or black smd near pin 3 ) go to the 21 pin interface IC (18599662-5). The resistence beetwen pin 3 and GND on board must been 150 - 2500 ohm. Chek all this values. And good luck. P.S. At my board resistence beetwen pin 3 and GND go to Mohms. And after change interface IC all problems solved. |
