			The Performa 400 is a rebadged LC II (16 MHz 68030, "pizza-box" case). Use the LC II page for its power-supply, recap and video diagnosis.

			== Common faults (shared with the Macintosh LC II) ==

			As with the Macintosh LC II, 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 II Troubleshooting]]'''.
