Repair guide for an ASUS B150M-C board identified as D620MT-DP_MB, which appears to be the OEM board designation used inside an ASUS D620MT desktop; the archive is an 887 KB RAR. Check that the marking on the PCB matches both identifiers before relying on the material. Such guides help trace power sequencing, measure rails and locate failed parts on a non-starting board. Unpack with a standard archiver; contents and revision are not specified in the name.
