Bios For ThinkPad L13 Gen 2

[SMDFlea]

SMDFlea laptop serial number, full name and model, motherboard model is already in my messege. I clean efs, try clean me but motherboard not starting with bios(clean me "configured"), also i tried replacing the "bios" zone + clean ME but the board still doesn't boot. Many bios dumps that I found on the internet have a different version of ME (I have corporate lp) but the board boots up and shows the splash screen. I just started learning how to work with fit 15\16, so I don't really understand how to properly restore the bios.

As far as i know the 20VJ should have Consumer LP firmware, not corporate. Try the attached bios.

Where is the sticker with the serial number, on the base cover or on the motherboard ?

According to the serial number it`s 20VJ ,you can try the bios from a few posts up https://www.badcaps.net/forum/troubl...31#post3649231

The sticker is on bottom cover, but in bios bin file is the same serial number.
I tried bios that you suggested, but didn't work. Turn on, black screen, fan spinning, cpu get hot, ESC is light on.

Hi all,

I'm trying to recover a Lenovo ThinkPad L13 Gen 2 (Type 20VH) with a LAR-2 motherboard (19837‑1) and a MX25L25673G (32MB) SPI chip.

Backstory:

• Original BIOS chip was corrupt (4-note beep).
• I don't have a backup bios file
• Tried a dump from a forum (possibly mismatched) — still 4-beep failure.
• I’ve verified flashes and used UEFITool + UEFIExtract on the image.
• The board has BootGuard enabled (confirmed via FIT Table with __KEYM__ and __ACBP__ entries), so I suspect the current image has mismatched key manifests.

I’m looking for a verified working dump from the same board revision with BootGuard keys that match the fuse values for this type if possible.

Specs:

• Model: Lenovo ThinkPad L13 Gen 2
• Type: 20VH-0015UK
• Serial: R9-10974T
• SPI Chip: MX25L25673G (WSON 8) (actual chip MXIC 25L25673G)
• Original BIOS size: 32MB
• Boot failure: 4 short beeps (BootGuard triggered)

If anyone has a confirmed working dump or can help verify BootGuard compatibility, I’d really appreciate it. Happy to share anything I've tested or upload my backup if needed.

Thanks!
Darren
