    Hp envy m6 dead

    I friends, hp envy m6 not powered on, there is 19v at point .
    my pu301 pin12{VIN}=9V instead of 13v.
    my pu101 requirment all pins ok except pin5{acok}=0v
    PLS i need someones help have being dealing with this for 4days now without succes

            You have to find out +B on PQ301 & PU301 pin 12 13 3 6 20 Voltage ?

              Check the resistance PL302 /303

                PL303/303 AS no voltage, not short and theres ipeadance in both

                  i think the voltage going into pu301 [vin] is not enough for the ic to fuction. intead of 13.5 at pin12 am seeing 9v

                    from datasheet pu301 works from 5-24V

                      +13.5V from battery +19V from DC jack with +9V will not work
                      What is the supply on PR316 100k ? Second opinion remove PR316 injected supply and see if the IC is working

                          That's strange with +5V ?

                              @Akande, what help?? You have not responded to @techtiger's advise and measure voltage on those pins of PU301. First help yourself and then seek help.

                                      What voltage Do you get PR 112 B+ only with the adapter ? PQ301 PQ302 pin 5 voltage? Do you have another spare TPS51225C ?
