When I boot up my MAC 7100/66, nothing happens. I don't even get the startup chimes, but I do hear hard drive activity. Note: This machine was working fine with a scanner and a jaz drive hooked to it.  I unplugged all the external SCSI devices, went to startup and nothing! Any suggestions on what to do ?

Gimmie,
Turn off the computer, then go to the back of the CPU and check to see if the monitor cable is plugged in snuggly. You might have loosen it while unplugging the SCSI cables. Now turn the CPU and the monitor on and do a start.

Yes.  There's only one hard drive in the whole machine and no CD-ROM.  I have a feeling its a SCSI problem, but I've tried everything I can think of.

ack!!!...i totally forgot about that!!!....rickyr is probably exactly correct. However there is a way around it that usually works. You can jumpstart it. Turn the computer on and let it rev for a second. Then turn it off and back on REALLY quickly. This usually works.

If changing the battery does not work...your power supply is dead.

So was it the battery??  Another suggestion here:  aren't you supposed to cap off your scsi chain?  Maybe it doesn't matter if you haven't got anything connected--I can't remember.

Oh, yea...the startup chimes thing could be due to your setting your volume to mute before the problems started--seeing as the setting before shutting down is now carried over to startup.
