Franco Where did you get the Battery Calibration Tool from. I checked the IBM/Lenovo site and found nothing.
I have the Power Management, Battery Maximiser Gauge and ThinkPad Configuration utility. None of these have any calibration tools or options. It is just confusion. I just charged it and it stopped at 70%. I am now running off battery. Task bar say 0%, Maximiser Gauge says 68% after about 5 mins on battery, which is about right and the battery light under the keyboard is flashing orange. All I want is for the battery to register how long it will last. Also under Ubuntu removing the power plug while running causing the machine to hang - flashing the caps lock and scroll lock. I would like to over come this too. If I cannot get round this problem or it is indeed a faulty battery I will send it back or accept a partial refund.
