You're the second person to suggest that Carol has a bad drive or file system problems. I don't see how people are making this leap as nothing she has said gives any credence to this. To the contrary once she rearranged some of the internals of the machine (which causes settings to be reset) it booted as expected into all of her partitions - until she powered it down, whereupon the booting problem reappeared. Sure sounds like a battery problem to me. Given all the myth and superstitious behavior that goes hand and hand with Mac trouble shooting I'd suggest that people make a note of the following site: Mac PRAM, NVRAM, CUDA/PMU & Battery Tutorial: What, When & How? http://www.geocities.com/texas_macman/pram.html Apple's Knowledge Base also has trouble shooting guides for various problem situations. Carol, you might want to check out: PRAM Battery Checker at http://www.polar-orbit.com/software.html . Phil
