Dell Latitude 7280 LA-E122P is a laptop motherboard designed by Compal and used in the Dell Latitude 7280.

The catalog has 1 schematic, 1 boardview file and 5 BIOS files for it, posted between 2021 and 2024 across 2 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 and .BRD 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 1 MB and 16 MB chip sizes; some archives also hold EC/KBC firmware; versions with a cleaned ME region are included. 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 CAZ10.

How do I open the LA-E122P boardview file?
The boardview for LA-E122P is available as .BDV and .BRD. .BDV and .BRD usually opens in OpenBoardView (free) or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the LA-E122P BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 1 MB and 16 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.
