Is it common for these things to cause problems if there is no expansion card hooked up to them? Or would that only happen if the converter is defective?

I'm sure the one I replaced it with is not very new (I just pulled it off the spare IIsi board), but it seems to hold enough charge to keep time and settings while the machine is off. The battery probably isn't the problem, but maybe a brand new one *would* do some good... > > > >I have a spare IIsi motherboard, but I am wary to swap them as this > >problem doesn't really hinder my usage of the IIsi in any way other than > >forcing me to set aside 10 minutes of my time 'warming it up'. > > > >I'm just curious as to what would cause symptoms such as this.
