    well if you inject on source of QO902 with a pwoer lab transformer you will noticed 98% sure that wy««you will find a short on cpu vcore circuit , since its usual on this machine ..alltough usually Q1131 is damaged

          schematic?...i think never release to public or web.. belong classified document


          Did you see marking code on QB2?

          IMO
          Q=Mosfet
          B=Battery

            thanks for your reply
            that QB2 is on HDMI section
            my laptop didn't regconize the HDMI cable and that QB2 was short to ground, but i fixed it, took that out and replace new PCH, it works probadly

                  HP 15-d014 osamu2_cr_hpc schematic

                  Does anyone has the schematic for this motherboard?
                  I have a black screen on the laptop, and I have found that the L1331 has no power. On the Q1331(6414A) I have 19V on the Drain, but nothing on gate so nothing on Source. And I don't know where the gate on the circuit goes to find out why it has no power.

                  I also attach a photo of the point of the board.

                    after a lot of search on the board I found that the Gate of the Q1331 goes to U1302 on the 8th pin. The component writes on it ALZ. Does anyone know what this is???

                      it would be good if you take a photo of U1302 and its surrounding components. I do not find it in the first photo.

                        You are right, I forgot to upload the photo. It's on the other side, next to the LVDS connector.

                          U1302 seems to be a MOSFET driver IC. I recommend finding the schematics first.
                          without schematics , you cannot discover why there is no voltage at the gate of that Mosfet. Probably, U1302 is not bad because its inputs are not provided.

                            Hi, I think the U1302 chip is an NCP5911.

                              I have search on the internet for the schematic, I haven't found it either to download, or to buy.
                              I made some measurements on the U1302 and I have
                              pin 1 - 5V
                              pin 2 - 2V
                              pin 3 - 5V
                              pin 4 - 5V
                              pin 5-8 - 0V all of them
