hi, my duo 270c has broken, so now I'm using a new powerbook 280c upgrated to 2300c it is a nice machine, but I got a little problem. I'm using a reconditionated (by my father) battery of the old duo 270c, and the "living time" with the 280c/2300c is more short: the same battery give me 1h30m using the 270c, and only 40/50minutes using the 280c. I try to use the battery recondition utility, but it do not work: the application start, the screen became white with the battery icon jumping here and there, and after 10 hours nothing is changed, white screen, battery jumping, and I have to quit application. I try to reset power manager, but nothing changed. Is this a normal problem using a 270c battery on a duo 2300c? Thank you for the answer. f. --- http://www.venerandi.net/
