dell Battery charging trick and concepts.. Using N5110_DQ15

Post by Arun.shspl »

[hidden]Name of some important signal in charging section
Acin, acok, psid(Signal or say communication with adapter EEprom), communication between charging IC and Ec (npce975p), Communication between battery and EC

In N5110 motherboard its a signal named psid_Id directly communicate between adapter and EC pin 99 there is an EEprom Ic in adopter which gave the information about the watts. This line in another model have some protection parts we will describe in pdf. you can see adapter information in bios to understand that adapter is being sensed or not.

Now we will look the Charging Ic input signal and other parameters:

pwr_chg_Acin is an analog input thru a resistors divider by which ac in sensed, Dc in is PWR_CHG_DCIN is the vcc for charging ic after initialize the charging Ic generate AC_Ok signal which is 3volts High and by Q4001 inverted its become ac_in# or psl_in which is Zero(Low) its reached to EC named psl_in Pin no.73 by this EC sense adapter inserted.

Also check the scl sda on charging ic pin No. 9 and 10
same communication between battery and Ec Pin 69 and 70

for another model Like N5010 there are some component same as attached :
Generally 33Ohm resistance get open,and q6, q7 also get faulty..
