Dell Inspiron 5575 LA-F121P is a laptop motherboard designed by Compal and used in the Dell Inspiron 5575 and Dell Inspiron 5775.

The catalog has 2 schematics, 2 boardview files and 6 BIOS files for it, posted between 2019 and 2024 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1.0 and Rev 1.00). 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 is packed in an archive and the file name does not say which format is inside; most open in OpenBoardView or FlexBV. What Is a Boardview File and Why You Need One lists the common formats.

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 and 16 MB chip sizes; 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.

Also listed under platform CAL51.

Frequently asked questions

Which laptops use the LA-F121P motherboard?
File names in the catalog tie LA-F121P to the Dell Inspiron 5575 and Dell Inspiron 5775. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-F121P do I have?
Files for this board mention Rev 1.0 and Rev 1.00. 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-F121P boardview file?
The LA-F121P boardview comes inside an archive whose name does not state the format. Unpack it and check the extension; most laptop boardviews open in OpenBoardView or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the LA-F121P BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 8 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.
