Compal schematic in PDF for the Dell Latitude 14 5420, project GDF40, board LA-K491P. Compal uses the LA-xxxxP board numbering, and Dell projects carry their own codenames such as GDF40. The pages show power rails, the charging section, CPU and memory power, and the signals that control startup, which makes it useful for no-power and short diagnosis. Check that LA-K491P is printed on your board before relying on values. Opens in any PDF reader.
