FAQ & Answers

Yes ,I found there is a BQ9000 IC from Texas instrument on battery pcb ,I read it's new branded data sheet and reference manual (bq4050) , and I know there is SMBus V1.1 interface to connect to it .(but i don't have any module which support it ) ,But ,I think STM32 has this feature in it's UART configuration , I will check it but ,I don't know will doing this stuff works finally or not ?!
Also I've seen there is a pin named PRES which I think it is useful in situation like this ,But as datasheet says I've connect this pin to VSS with 10k ohm resistor but nothing has happened .
So any help in this way will help me .
(Also I can not purchase new battery from other country at this time so I should repair it by my self (Also I am an electronic engineer so maybe with a little help I'll be able to fix my problem ) )
And if this problem is just because mAh of new batter ,I can change to same mAh battery .

(The last one is not from report it is from a software i found on internet).
and there is a website which has some detail about my batter it's address is :

and a screen shot of the website :
He or she said if we connect yellow wire to GND it should enable battery output but it did not worked for me !
I'm one hundred percent sure it should have something like what is in below video clip on youtube :

------------------------
even if it does not have something like this and it needs to connect to battery with SMBus interface because windows has it's interface (which by that it can connect to battery and talk to it ) ,There should be a software or .bat or something like to fix the battery .
It's very bad a battery ruined two day of my life ...
