About this board
Files for the HS450 SVT U49 motherboard, board number NM-D231.
LCFC (Lenovo/Compal) board numbers start with NM-. Check the number printed on the PCB before you download. This listing is for revision 1.0; another revision of the same board can need a different file.
Files usually needed for this board
- BIOS (full SPI chip dump, .bin)
- EC / KBC firmware, if the board uses a separate EC chip
- 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.
Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.
