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...

Hi,
had T490 with faulty bios chip. Bought chip out of ebay and soldered on. Laptop starts and works however serial numbers of laptop and motherboard do not match.
I have updated laptop model number.
1) I did not find the way to update laptop serial number - I have this one.
2) I dont know where to get my motherboard serial number and how to update it. Is it somewhere physically on the mainboard? How do I update it?
Hope to find someone to help me with this as I am hitting dead end at the moment.
Many thanks

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.

After adding the chip save the xml file and copy it to the root directory of the... -
I was wondering if you more experienced technicians could help answer some basic questions I have ... and help me build a reliable work-flow for using my new XGecu-T76 Chip Programmer (running XgPro v13.17). I like being able to leave the chips soldered-in (when possible) and read/write them with pogo-tool.
As instructed, for more reliable operation with pogo-tool, I have backed the SPI-Clock Frequency down to 16-Mhz (and that seems to be working fine so far for reading/erasing/writing/verify).
So, let's say I have a MB that soft-bricked itself after a common BIOS-Firmware... -
