Clevo archive of 34.4 MB referencing boards 6-71-N24J0 with the DB2 suffix and 6-71-N24W0; the name does not say what the files inside are, so check the contents after extraction. Clevo numbers its PCBs in the 6-71-xxxxx format, and these machines are sold under many reseller brands. Material for such boards is used to trace rails, find components or reflash firmware depending on what is included. Compare the number printed on your PCB, including any daughterboard code, before relying on it.
