Sometimes one bad electrical contact will stop a machine. Surprisingly it does not take much corrosion or crud at all . If the battery is alive and the machine does not start you might try cleaning the battery contacts in the holder. Sometimes just spinning the battery in place is enough to break through the insulating coating whatever it's nature. If the machine still does not start try cleaning some more important cable and power connections. Is the power switch on the keyboard? My older Macs have had corrosion deadened circuits blocking the ADB link after sitting for a while. This gets multiplied when connected to a KVM setup as mine was. I have run 604 systems sans battery. === I've been using a IIci offline since 1990. Changed the battery sometime in the 1990s and again several weeks ago. For several years, the clock would lose about one minute every three days and then about three or four weeks ago the clock started to lose over an hour each day. So I replaced the PRAM battery with a battery that tested at 3.7 no load volts. Now it gains about 15 seconds each day. The old battery tested at zero volst - no measurable voltage yet the IIci booted and ran all functions with that flat battery. Great machine for what I use it for.
