My Q800 seems to work fine. I can't think of anything wrong with it. Oh, wait. Yes I can. The clock battery is dead.

In any case, I'm realizing that if I'm going to invest any more in this machine then I had better ensure it has a long life ahead of it.

I'm particularly interested in ensuring no component self-destructs and takes others with it, but that's not the limit of my interest.

Can anyone give me a simple checklist for actions to take for this particular model? (apart from replacing the clock battery, of course)
