I had the same thing happen when the battery went on my Toshiba Tecra 8000. In fact, the symptoms were EXACTLY as you described. I got a battery pretty cheap, but don't remember where. I probably have the receipt at home. If I get a moment to actually go home today, I'll look. You can probably find it at a good price if you just check Pricewatch. That's the way I found the good deal.
