    Can someone please explain to me what this chip is CM03X

    Can someone please explain just what this chip is suppose to do and how it works

    The data sheet is very vague about what this chip is

    CM03X

    Looks like just a MOSFET switch meant to be run in saturation, of sorts...where is it being used?

        the datasheet say

        The CM03X is designed to reduce the no load consumption or
        so called Phantom power for AC Adapter, Desk Top PC power
        supply, LCD Power Supply and others.

        but they can add typical installation

          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...

          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.

          Asus Chromebox CN62 - wrong chip put on BIOS reader
          by BMCappelletti
          Long story short:
          - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
          - gave the computer to his son a couple years later
          - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
          - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
          (seems like the story was not that short)

          He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

          Acer e15-e5-576g-5762 bricked. Bios chip won't interface in AsProgrammer.
          by inck243
          Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.

          The BIOS...
