    HP ProBook 450 G3 DAOX63MB6H1 no turning on

    Hello, please help; i have this notebook, when i plug in the charger, power led is light white a little bit and that's it.

    With charger insert, only mainboard, no ram, no bios battery, no keyboard, no display, i have:
    Input voltage go through first 2 mosfet's and current sense resistor.
    At PL29 i have 5volts.

    Without charger, i have:
    On PU2, on PC2 +3VPCU to GND i have 2,5ohms
    On PL16 +1.0VS5 S2 to GND i have 0,1ohm; that's is not correct, right?

    I attached boardview and manual; thank you.

      Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
      If I let battery run out and say it has 3% Windows will...
