Duo 210: I have bought a Powerbook Duo 210 with the DuoDock but the battery it´s died and the only way it works it's inside the dock and atached to my Performa so I have no idea if the display works. Can you give me information about the power adapter jack? the kind of jack or the poles... Or do you know a way to test the display? I can take off the DuoDock cover and operate the powerbook inside (the trackball, keyboard, watch the green led) but the display it's of. Sincerely Moises Mariscal (SPAIN)
