HP 15-BS LA-E811P is a laptop motherboard designed by Compal and used in the HP 15-BS and HP 250 G5.

The catalog has 1 schematic and 6 BIOS files for it, posted between 2018 and 2025 across 4 Telegram channels. Each download button opens the original Telegram post.

File names mention 3 board revisions (Rev 0.0, 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 schematic is a PDF; the first pages usually hold the block diagram and the power sequence. New to schematics? Start with How to Use a Schematic and a Boardview Together.

BIOS notes: some archives also hold EC/KBC firmware. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Frequently asked questions

Which laptops use the LA-E811P motherboard?
File names in the catalog tie LA-E811P to the HP 15-BS and HP 250 G5. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-E811P do I have?
Files for this board mention Rev 0.0, 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.
What should I check before flashing the LA-E811P BIOS?
Read the original chip with a programmer and save two copies before writing anything. 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.
