        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...

        ASUS TP412F 3.3V Regulator chip gets very hot
        by mferna14
        Hi all., I am working an ASUS TP412F​., motherboard Model TP412FAC R: 2.0. The problem I am facing is the 3.3 buck converter (L8=7J RT6256BGQUF) gets very hot when 19v is applied through DC-in jack. I don't think Schematics or Boardview is availble for this model. The chip get so hot that I can't even take the voltages of the pins. I replaced the chip but the problem is still there, new chip even gets very hot. The input on pin 5, 19v is present. So I removed the Output coil & the chip & checked the voltages on the chip pads which are as below: Please view if any volts seem to be abnormal....
