    DELL INSPIRON PS_ID PROPLEM AND FIX

    Hi
    I had a nice dell laptop yesturday,the proplem was it is not charging...
    i try another orginal charger with no luck also another battery no change either
    the famus massage that the ac adapter wattage in not reconize by the laptop always show at the boot
    in the bios the ac adpters is unkhown
    so it is a motherboard issu, first i download a boardview to know what i am abut to deal with
    then i extract the motherboard to start trace the voltage
    the 19.5 line was ok but the ps_id was 4.2v it shuld be 3.3
    the signal came from super io chip so that where i start and gladly it was 3.3v
    then it go to pin numper 1 on PD5 then to pin numper 1 on PR3 and pin numper 2 on PR4
    until here every thing was ok
    next the signal go to PQ6 and here was the proplem, on pin numper 3 it was 3.3v which is normal
    but on pin numper 2 the voltage was 4.2 insted of 5 casuing the rest of circute to fail
    by replace PQ6 the voltage staple at 3.3 on ps_id pin on charging connector and the laptop is charging again
    i hope this informations became useful to you​
