p900 can't charging, - GSM-Forum

genocite · 05-09-2004, 06:11

got p900 which can't charge, if resistance measured between the battery + and - legs, shows a bit of resistance leakage, if the power supply 3014/2c was removed, the resistance leakage was gone, if the pa was removed, the resistance leakage decreased until a very small value, also already changing all small part including charging ic around all the power supply module, any idea which part or section maybe defective ?

thanks a lot for any input

regards

@genocite..
how u solve it ??

I have problem on P900, when I charge the battery till full and switch it on. The battery indicating it's empty but the led is green. The I try to make a call, the low battery warning will appear. I replace the battery with new one, but the problem persist. Any idea how to fix it, and which part is fault?

just check battery connector soldered side may be bad soldering resolved problem like yours this way

where is the A G transistor you are talking about... where is it located?

malta · 08-09-2005, 14:42

up near the led indicator

SIXTUS · 08-11-2005, 09:40

ok i will try and post result,.......

I don't have the schematic for the P900. Can someone who has it send it to me. What is the part number of the A G transistor? If you could give me the some description of the transistor, it would be helpful. thanks a lot.

Measure between the legs on the transistor labeled 6F near blutooth led.

On mine P910i it was only 10 ohms between 2 legs so I exchanged it with a transistor from a old R310s board it is located close to the backup battery on R310s.
Look for the label "6F".

Best regards Daniel

best solution:
1: check system connector
2: Replaced N701 (IC near system connector) (main cause)
3: check some capacitor (round the N701)
4: check IC power.
