RAR archive for a Compal board numbered LA-K161P, labelled as OK and tested by whoever prepared it. The name does not say what is inside, so expect a BIOS or EC dump, boardview or schematic until you open it, and it names no laptop brand or model. The LA-xxxxP pattern is Compal numbering, used on machines sold by Dell, Lenovo, HP, Acer and others. Confirm that the LA-K161P marking and revision silkscreened on your PCB match, and if it holds a firmware image, read and save the original SPI chip with a programmer before writing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @hrtechno. Enginerys does not host this file.
