HP 15-BS LA-E791P is a laptop motherboard designed by Compal and used in the HP 15-BS, HP 250 G6, HP 15 BS011LA and HP 15 BS526UR.

The catalog has 1 schematic, 1 boardview file and 21 BIOS files for it, posted between 2018 and 2025 across 5 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 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 CSL52; codes LA-E801P.

Which revision of LA-E791P 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-E791P boardview file?
The boardview for LA-E791P 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-E791P 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.
