On the AD_ID pin I get 12v, the computer charges, turns on and everything works.

I tried, but nothing changed, I inject 2.4 volt with my power supply without changes, battery not charge, if I measure with tester on BATT+

On AD_ID nothing... 0 volt.
I've tried set power supply to 21v but nothing change
On DC Jack it doesn't turn on the light

I see the light, only when I unplug power supply cable from dc jack, it blink just one time and stop....

If I inject 2.4 volts on ACDET with my regulated dc power supply, it is not the same thing ?

Yes, I can take other resistor to from other bad board....but I've never done this
If I found an exact 430k resistor as in schematic for PR1031, that would be much better...

Yes, 19v5 stable.

I've on ACDET PR1032 with 38 kohm and PR1031 with 38 kohm measure to ground
If I measure resistor PR1032 I have 49 kohm and on PR1031 247 kohm, on schematic I should have on PR1031 430 kohm
