I called the tech support center, and the person who answered the phone did,
indeed, agree to send me the manual; he wanted to know why I wanted it,
however, since they normally send them to people who want to build things to
go in the machine.
I asked him about the battery discharge phenomenon, specifically about the
degree of discharge when the machine starts beeping or switches off. He
confirmed that the battery is not fully discharged when this happens, and
seemed to be aware of the resistor trick mentioned in another posting here.
He said that they don't recommend it because most people don't have the
technical background to use it (?), but that it was not likely to harm you
or the battery -- unless you drain it TOO far. I'm not sure how far that
is, or how long it would take to get there, but I'm planning to go out and
get a 10-ohm resistor ASAP and try it...
Thanks to the poster who supplied this trick!

Why not buy a cheap battery discharger for a radio controlled car? You can get a decent one for less than $30, and they usually come with an ammeter and a timer for controlling the length of discharge time. The only modification you'd need to make would be to change the connector to the proper one for your battery (I'm, of course, *assuming* that this is the way the battery is constructed for laptops.) If you get a charger/discharger, you could have several battery packs ready to go. That way, you'd only have to switch the packs. I make no claim to know how laptops work. Heck, I don't even own one (...yet. The urge is growing, though. |-) > Jon Pastor pastor@prc.unisys.com SJO
