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

by TrademarkHello everyone,
I’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.
This is NOT a BIOS password removal request.
I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.
Laptop Information- Model: Acer Predator Triton 16 PT16-51-99GL
- Motherboard: DA0ZQDMB8AE Rev. E
- Main SPI flash: Winbond W25Q256JVEN (32MB)

Good day.
I'm seeking information, advice, or fix for a BIOS upgrade that is always failing on a Thinkpad X12 Detachable Gen 1 (Wistron 19835-1). The failure is indicated as "An unexpected error has occurred, and the process did not complete." as shown in (1) whenever I try upgrading the BIOS via the provided official BIOS bootable CD or BIOS Utility (Windows) update releases, practically EVERY version released for this unit as can be downloaded in (2). I acquired the unit as second hand, and the sticker labels like the CPU/Manufacturer logos and even the factory labels...-

Mobo: NM-B562
I'm attempting to revive an out of warranty Thinkpad P52 that failed a BIOS update last year. The update stalled for hours until it was manually shut down. Since then, power and keyboard lights come on briefly, but no display. Its diagnostic beep tune returns as 0285 "TCG-complient funcationality-related error (might be the TPM initialization failure)."
I've just received a CH341A programmer and cleanly read the memory, but was unsuccessful at patching my own binary from Lenovo's iso....-
