            Measure → V(TP(ACDET)) = 2.6 V ± 0.1 V
            Measure → V(TP(ACOK)) = 3.3 V ± 0.1 V
            Measure → V(J2(SYS)) = 19.5 V ± 0.5 V
            Measure → V(TP(REGN)) = 6 V ± 0.5 V
            Measure → V(TP(ACDRV, CMSRC)) = 6 V ± 0.5 V
            Measure → V(J2(BAT, GND)) = 2 V ± 2 V


            from yours
            ACOK is not good pin 5 =0.02v must be 3.3v

            pin4(acdrv)-pin3(cmsrc)=6v in your case pin4-pin3=18-0.03=18v so it is not good

            ACDRV must be 24V or 25V and CMSRC 18v or 19V

            24-18=6V and 25-19=6V (correct voltage )
            Thanks a lot for your help, very helpful informations ..

              check for continuity and also replace the 3 mosfet N type 4466 even if they seem to work.
              Thank you, dycc! You saved me from lot of trouble finding why the charge pump is messed up.

                  HP Probook 470 G4 - Power and Charging Problem
                  by Scoff
                  Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
                  Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...
