I am after a good working BIOS for the following Lenovo Notebook Please:

ThinkPad T15 Gen 2 (Type 20W4, 20W5)
SN: PF-3HK7AN

Negotiates ~19v, Power button pressed and it tries to start (fan spins) climbs to ~0.8-1 amp then drops back down to 0.05amp

Current BIOS File backup attached

Thank you!

Thank you for providing BIOS so quickly. Did not fix my specific issue but I can rule out BIOS hopefully with your new image.

Try to update only the U2201 first with this content:

Unfortunately, the BIOS file you sent didn't display a screen. I have another identical device, and when I copy its BIOS to my motherboard, it takes a while to display a screen. If you could share a different BIOS file with a clean ME performed, I would appreciate it.

Here is your file with new BIOS and cleared MR Region.
If it's not boot up then I will perform a clear ME on your original BIOS dump hoping the BIOS region is not corrupted...

Hello friends, I have a problem with this T15 Gen 2. The power consumption reaches 0.350 and then it restarts. I’m attaching both BIOS files. I need a working BIOS, or if someone can check whether these BIOS files are correct. Thank you.

Serial PF-3B1YZ1, type number 20W5-S26E00.

HI TRY u2201

[nicoar10]

The motherboard is still behaving the same way. I replaced U2201, but the behavior remains unchanged. I tested it with both BIOS chips removed, and the power consumption is 5V at 0.30A, but it stays stable and does not restart.

Hi, Try again by flashing this BIOS file onto the same U2201 chip

It behaves the same way. Thanks anyway. What's strange is that if I remove the BIOS IC, the voltage on the USB-C port remains stable and doesn't keep restarting. However, with the IC soldered onto the board, it keeps restarting all the time.

hi try this one

It works, but very slowly, and the fan runs very loudly all the time. Every time I restart, it displays "firmware failed," and I have to shut down the computer and restart it.
