Dell Inspiron 5455 LA-C142P is a laptop motherboard designed by Compal and used in the Dell Inspiron 5455, Dell Inspiron 5555 and Dell Inspiron 5755 A12.

The catalog has 1 schematic, 1 boardview file and 7 BIOS files for it, posted between 2017 and 2022 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1.0 and Rev 3.0). 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 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: 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-C142P motherboard?
File names in the catalog tie LA-C142P to the Dell Inspiron 5455, Dell Inspiron 5555 and Dell Inspiron 5755 A12. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-C142P do I have?
Files for this board mention Rev 1.0 and Rev 3.0. 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-C142P boardview file?
The boardview for LA-C142P is available as .BDV. .BDV 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-C142P 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.
