ok thank you i read it, i'm beginner in mb repair and i dont know if it must be present in all power condition. I assume that it will be always present.
Is the same thing if I remove pl2 instead of pr28 (only for comodity)?

Hi to all,

ADD
-PSU ONly
-BATT only
-power connector
-protection circuit

I had checked every pin of BQ2472:
-pin 7 according to datasheet "IOUT voltage is 20 timesthe differential
voltage across sense resistor"
maybe is too low?It also connected to protection circuit.

Is normal that the ENE-KB930 is hot with only power adapter plugged?
