Dell Latitude E5430 firmware pair, BIOS plus EC, for the Compal LA-7901P motherboard with project code QXW00, in a 5.52 MB RAR file. Dell business laptops of this era carry a separate embedded controller image, so a dead keyboard, charging fault or no-power condition sometimes needs both chips reprogrammed. Use a programmer such as a CH341A with a clip or remove the chip for reliable reading. Always dump and archive the original contents before writing, confirm the board number on the PCB, and check that file sizes match the installed flash chips.

How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
