I'm havin trouble with my laptop. Whenever i unplug the charger, it will say it has around 3 hours of battery life left, but it realy drains down to zero within 10 minutes. My power plan is set to power saver but it still drains realy fast. i have to have it connected to a charger all day to use it and this kinda defeats the purpose of the laptop... The laptop is a Fujitsu Lifebook T series.
