RAR archive of about 1.12 MB for the Lenovo G430, tagged LE6, which appears to be a platform or board code rather than a standard Compal LA number. The name does not state the document type or revision, so check the contents, likely a schematic, before use. Drawings like this let a technician trace power rails, check charger and CPU power circuits and locate components around a short. Compare the code and revision printed on the motherboard with the title block before trusting component values.
