Do not use the generic Acer driver auto-detect tool. Instead, go directly to the section. Enter your Aspire model number (e.g., Aspire M5620 ), not “MCP73TAD.” Under “Documentation,” look for the Service Guide . The service guide (not the user guide) contains the full motherboard layout, jumper settings, and BIOS recovery procedure.
