The Macintosh Performa 450 is a Macintosh Performa rebadge of the Macintosh LC III — the two are the same hardware, sold under different names and bundles.[1] Because the logic board, analog board and power supply are identical, the Macintosh LC III Troubleshooting page applies in full: use it for power, video, capacitor, storage and audio diagnosis.
The Performa 450 is a rebadged LC III (25 MHz 68030). Use the LC III page for diagnosis.
Common faults (shared with the Macintosh LC III)
[edit | edit source]As with the Macintosh LC III, the first steps on any un-serviced unit are to replace the electrolytic capacitors and inspect for PRAM-battery leakage and its corrosion, then confirm the power-supply rails. Full detail, test points and fixes are on Macintosh LC III Troubleshooting.
