Did it remember ?its bootdevice? If not then the battery is probably gone. It may be
replaced, but I've never taken the trouble.
It did boot, right?

The battery can?t be replaced by itself, since it is embedded in the TOY chip, which is a
DS1287A. That chip is not made anymore, but there is a drop-in replacement (Maxim
DS12887A) which can be obtained quite easyly. The datasheet is this one:

Alternatively, it is posible to plug in another battery to the dead DS1287A:

I try to do it and failed, so I got some 12887 to keep my 4000? running.
