Schematic for a Dell laptop board LA-J522P at revision 1.0, provided as a 4.45 MB PDF. The LA-xxxxP number follows Compal's scheme, so the board was designed by Compal for Dell, and the exact Dell model is not given in the name. The document helps when diagnosing no-power faults, following always-on and main rails, and identifying circuits around the charger and EC. Open it in any PDF viewer. Verify the board number and revision printed on the PCB before using its component values.
