Lenovo 5000 DG42A NM-B244 is a laptop motherboard designed by LCFC and used in the Lenovo 5000 DG42A and Lenovo IdeaPad 320C-15.

The catalog has 2 schematics, 2 boardview files and 6 BIOS files for it, posted between 2019 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev 1.0; other revisions of the same board can differ in parts and layout.

The boardview comes in .BDV format. OpenBoardView (free) usually opens these files; FlexBV works too. See OpenBoardView: Installation and First Steps.

With both a schematic and a boardview you can find a net on the diagram and then locate the same part on the board by its reference designator. No Boardview for Your Board? How to Work Without One shows the workflow.

BIOS notes: file names mention 8 MB chip sizes; some archives also hold EC/KBC firmware. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Files for this board mention Rev 1.0. 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.
How do I open the NM-B244 boardview file?

What should I check before flashing the NM-B244 BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 8 MB images; the dump size must match your chip. Some archives include EC/KBC firmware, which may need to be written to a separate chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
