I've just bought my first laptop which has Vista Home Basic & 2GB of
RAM. According to the sales literature the battery life ought to be
2.5hrs but I barely get an hour out of a fully charged battery, even
with the wifi turned off and the screen brightness turned down. With
wifi on I'm lucky to get 45 mins. The battery model # is PA3450U-1BRS
& is allegedly 2000mAh. Is this par for the course or is it likely
that I have a faulty battery?
