I'm wondering how to charge a notebook battery (DELL) using my CV/CC power supply .
Battery has 9 pins
P+,P+
P-,P-
P-,C,D (I believe for SMBus communication)
SYS , I believe means "system present", because I have to connect to the ground to have output on P+,P-
ALE, I believe for thermstor
I though that just grounding the SYS, and connecting the power supply to P+,P- would be enough, but was not, I put power suppler in 12.9V/1300mAh (each cell of battery individually should be changer at 4.3v), but there not current flowing, the drain from power supply is 0A.
What am I doing wrong?
