About this board

Lenovo slim7 — motherboard DA0LS3MBAF0.

Lenovo had this board built by Quanta; Quanta board numbers start with DA and include MB. Check the number printed on the PCB before you download.

What this thread covers
  • BIOS (full SPI chip dump, .bin)
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search DA0LS3MBAF0 in File Finder.

Schematic only
the boardview isn't avaliable anywhere?

I am having trouble to find which diodes are these on the usb-c input rail. I've changed the usb c port but one diode flew away. after I tried to charge another component burned which I can't identify which component to buy.

last photo is the same area as the second and third photo.. same component.

I think it's a TPD4S012Four-channel ESD protection for USB interfaces, includes VBUS clamp...

it surely looks like a TPD4S012...


and the diode that's missing is either a Single-Channel TVS Diode or more likely something like PDZ5.1B Zener Diode... I don't know
