Before you buy a new power supply, try this: Get ahold of a cheap "power strip" with an on/off switch. Plug the IIcx into the power strip. When the IIcx is off, leave the power strip switch in the OFF position. When you're ready to boot up, reach down and flip the power strip on. Wait a few seconds, and press the keyboard power-on button. When it's time to shut down the computer, go through the normal shutdown procedure. After the IIcx "turns itself off", reach down and flip the power strip to OFF. Try this - you may be VERY pleasantly surprised with the results...
The theory is that the +5 V charge is still there briefly when you send current to the power supply. If you can start up the Mac quickly enough, you won't need the trickle charge while it's running.
Many people have asked me if I have a schematic for the power supply - I don't. Please send me one if you have it so I may post it on this site. Jan van Gennip did send some instructions (PDF) on how he repaired an Aztec power supply - thanks Jan.
I believe there are at least two makes of power supplies for the IIci, G.E. and Aztec. Mine is a G.E. and I haven't had a problem with it since I got it 5 years ago. Luckily, power supplies for the IIci are only around $15.
