    Mosfet marking AOP (AUQ) datasheet or ID

    looking for datasheet or ID of the chip has marking AOP AUQ. I checked on two other boards that i have and they show AOP AUR and AOP AUK.

    or its A0P?

    thanks

      it's on an Nvidia Shield.

      attached a picture of voltages on a working board.

      on the non working board, i have 5v only on pin 3 (under letter Q). other pins read 0 volts.

        I found the Micrel MIC5320 that is a dual output regulator, but has the wrong pinout

          just an update on the image with voltages. 1.8v should be 0.8v and pin with 0v should be between 0.4xV to 1.xxV voltage changes depending on load?

            Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
            by acedogblast
            This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

            There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

            ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
            by DynaxSC
            Hi

            I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
            The SPI chip is an Winbond 25Q256JWEQ model (1V8).
            The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
            The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

            I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

            Common SPI bios chip programming Questions and Answers
            ----------------------------------------------------------

            Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

            A: If you can`t read from it how do you expect to write to it ?.

            Q: Why is my bios chip unreadable ?.

            A: The programmer is faulty or has a worn or broken zif socket.

            The USB cable is frayed,connector pins worn or some other physical damage.

            Not enough amperage or voltage to power the programmer properly.
