Possibly recover from a dual CPU failure on a Mac Pro
Be extremely wary of this hint; older Apple models would be permanently damaged by being run without a CMOS battery. YMMV and you may very well break your computer.

Some years ago I saved a lot of G4's in a similar way. The machine wouldn't start, and the start button pulsated. Power cord out, battery out, count to ten, battery back, power cord in, start!

Permanently damaged? Absolute nonsense. Where did you hear this? I've been fixing Macs since 1985, and removed batteries from thousands of them, and run many without batteries, and none have ever been damaged as a result. When the battery dies, it's the same as running without a battery, and the Mac doesn't die under that condition either. It's not cool to start or perpetuate a completely untrue rumor which makes people leery of trying a troubleshooting method that often works, when PRAM/NVRAM is scrambled. If you've had Mac die after you removed its battery and powered it up, it had other problems, and/or you zapped the logic board with static electricity buildup on your body, etc.

Did you not ever come across the LC475?

Still, that's not exactly permanent damage, one must admit. |
