Lenovo ThinkBook 15P NM-E021 is a laptop motherboard designed by LCFC and used in the Lenovo ThinkBook 15P.

The catalog has 1 schematic, 2 boardview files and 2 BIOS files for it, posted between 2023 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 is packed in an archive and the file name does not say which format is inside; most open in OpenBoardView or FlexBV. What Is a Boardview File and Why You Need One lists the common formats.

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 1 MB, 2 MB, 8 MB and 16 MB chip sizes. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Also listed under platform HY520.

Frequently asked questions

Which laptops use the NM-E021 motherboard?
File names in the catalog tie NM-E021 to the Lenovo ThinkBook 15P. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of NM-E021 do I have?
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-E021 boardview file?
The NM-E021 boardview comes inside an archive whose name does not state the format. Unpack it and check the extension; most laptop boardviews open in OpenBoardView or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the NM-E021 BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 1 MB, 2 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.
