Lenovo ThinkPad L14 Gen2 - NM-C741 Rev 1.0

Hello, could someone make available the dump bios (E2102) and EC (E2104) of the ThinkPad L14 Gen2 - NM-C741 Rev 1.0?

I have a motherboard here with bad bios chip (U2102) and I've already replaced it with new chip and new bin, but I suspect U2104 needs to be reprogrammed and I don't have the file.

Model:ThinkPad L14 Gen 2
Type Number: 20X2-S6PE00
Serial:PF-3LNKB5
Motherboard: HL4A0/HL5A0 NM-D271 Rev.1.0

Thank you.

You can try the BIOS from Post #18, your BIOS is divided into 2 chips and you have to program both chips together.

Hi.

Will it be possible to explain to me how I program these two chips, maybe I am doing something wrong.
I have here two motherboards one is working and have i5 chip and only 1 bios. I took the opportunity to read the voltages of this one to check the other one that doesn't turn on.
The other have i7 chip and the bios chip location is u2101 the rom model is mx77l256sqfz and have second rom chip near I/O, location u2104, the model chip is w25q128jvpq.
it is so close to the I/O that I thought it was an EC, but the schematic indicates that it is a second bios...so I'm stuck here.

The laptop does not respond to the power button, voltages of 3.3v and 5v are present. On the 3.3v switch it drops to 0 when pressed, charging the batteries.

After connecting the power supply, the battery charging LED lights up and the power LED flashes 3 times.

The U2104 chip is not on the board

ThinkPad L14 Gen2
SN: PF2Z52EC
Type: 20X2-S0DL00

The original upload looks damaged to me because it is very different from the ones I downloaded here.

The 20X2 has 2 bios chips, 32MB and 16MB. If U2104 is where the 16MB chip should be then you will have to get one.
