Just got a new battery for my Lombard. When I push the button on the battery it shows three lights so I assume it is charged. However it will not boot the Lombard. When I plug it in the machine boots but the battery icon only shows and X. The battery is not being seen by the computer. Thye pram battery is dead in it. Could that be the problem? I already reset the PMU button. The machine runs Panther.
