Dell Latitude 5400 LA-G891P is a laptop motherboard designed by Compal and used in the Dell Latitude 5400 and Dell Latitude 5500.

The catalog has 3 schematics, 1 boardview file, 11 BIOS files and 1 archive for it, posted between 2021 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1.0 and Rev 2.0). Check the revision printed on your PCB before relying on a boardview or flashing a BIOS dump — How to Open .FZ Boardview Files explains why it matters.

The boardview comes in .BDV and .CAD format. .CAD files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. 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, 16 MB and 32 MB chip sizes; 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 EDC41.

Which laptops use the LA-G891P motherboard?

Which revision of LA-G891P do I have?
Files for this board mention Rev 1.0 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.
How do I open the LA-G891P boardview file?
The boardview for LA-G891P is available as .BDV and .CAD. .BDV usually opens in OpenBoardView (free) or FlexBV. .CAD usually needs FlexBV or the matching viewer. See What Is a Boardview File and Why You Need One.
What should I check before flashing the LA-G891P BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 8 MB, 16 MB and 32 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.
