          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...

          How to add chip support to NeoProgrammer software for the CH341A Programmer
          by SMDFlea
          Adding chip support is quite easy,there`s even some instructions included with NeoProgrammer,although its not obvious where they are
          and once you do find them there`s a few crucial steps missing.

          Extract chiplist.zip to a folder,the instructions are in Import_EN.txt and in Import.xml .Its the xml file where we add the new chip.



          Open Import.xml with notepad or any other text editor.In this example i`m adding a Macronix MX77L25650F SPI_NOR chip.



          After adding the chip save the xml file and copy it to the root directory of the...

          M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.
          by hotcrossedbuns999
          My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
          1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
          2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
          3. I could only locate two chips that look like bios chips. Could someone verify this

          ----------------------------------------------------------

          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.
