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

                  Re: Hp envy m6 dead

                  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

                      +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

                              @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 ?
