Frequently asked questions

Which laptops use the NM-A931 motherboard?
File names in the catalog tie NM-A931 to the Lenovo ThinkPad T470 and Lenovo IdeaPad T470. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-A931 do I have?
Files for this board mention Rev 0.1 and Rev 2.0. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
What should I check before flashing the NM-A931 BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 1 MB, 8 MB and 16 MB images; the dump size must match your chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
