Re: Lenovo x240 how to locate TPM CHIP
there should be no other chips with the same features, without a schematic you have to desolder the chip or one pin and restart the system. If there is an error in the boot that is the right chip.Comment

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.

Hi,
Anyone here know the name and model number of the Super I/O chip in the L540 20AU (HM86 EXPRESS CHIPSET)?
I need the information to solve an issue in Linux Mint, where fan is not detected correctly.
If anyone know the exact name of the sensor that show fan speed it would also be great.
I tried looking on my motherboard but can't see it without taking the laptop apart and I really don't want to do that. I asked Lenovo, but they are not answering. I searched google for photos of the motherboard but they were too blurry to read anything, according... -
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...
