This guide provides systematic, component-level troubleshooting for the '''IBM PC (5150)'''. It covers the POST audio beep codes, the complete numeric error code list, parity errors, video problems, keyboard 301 errors, floppy faults and known motherboard problems. The 5150 has no battery-backed CMOS — all hardware configuration is set through DIP switches SW1 and SW2 on the motherboard, so verify those before chasing a hardware fault. | This guide provides systematic, component-level troubleshooting for the '''IBM PC (5150)'''.
