But if memory serves, the lights should all come on, but then it should start a diagnostic from firmware and you should see the rightmost lights counting up low memory. If you never see this, it indicates a memory problem most likely. The first thing to check is those ribbon connectors inside the front that daisychain all the memory cards. I'd suggest taking them off and cleaning the connectors and edge card traces with a good gold contact cleaner, then reseating carefully and try again. I seem to recall that one of my 21mx's took a good 4 minutes or so before it started the memory test. I also seem to recall that if the machines had the power fail restart option, if memory wasn't maintained due to a dead battery or something that the machine would come up in a strange state and you had to do something wierd like turn the machine on while holding store or something like that. If you still have trouble, I'll look up that procedure for you. Hope this helps. Jay West
