problem with N3210 charging - GSM-Forum

fiZ · 06-29-2002, 14:36

when battery sits, not possible charge,only when put in other 3210,a litle to charge,and then it begins to charge.Such feeling, what telephone of vastly powerfully unloading a battery and subsequently can not begin to charge,give little taking from other telephone and then this itself begins, be charged.What thoughts?

Sorry for my english

If when you calling the phone display "LOW BATTERY" and battery is full charged, first of all you need verify phone consum. Take a 3v power supply and an ampermeter, power up the phone and make a call. If the consum is more after 300 mA your phone is damage (

), else verify charging circuits and of corse battery.

Cris

Try to:
1. Verify and resolder battery contacts;
2. Reflow charging IC ( situate between antenna connector and CCONT)
3. Replace charging IC

Best regards,

You may also take it form other 3210

If you like to buy it try to find a distribution point in your contry. Thing there is a lot of people with this "hobby"

but is charging IC glued on motherboard?I must warm its on the other hand?

P.S. i always have new charging IC

No, the charging IC is NOT glued on PCB; it`s only soldered by micro BGA tehnology. You need some skills to replace it.
Into Nokia 3210 ONLY processor (MAD) is glued and can not be replaced.
