Archive for the HP Compaq NX6320 business notebook, 1018 KB in RAR format. The name gives only the model, with no board number, revision or contents listed, so check what the archive holds after extracting it. Typically such files are schematics that let a technician trace power rails, inspect the DC-in and charging circuits, and locate components on the board. Match the board code printed on the PCB with the documentation before relying on any values.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
