    The last week i have gotten a battery capacity warning every time i disconnect the power cord. The warning states that the battery only has 74% of its original capacity. I havn't done a proper complete battery drain test yet, but the feeling is that the warning is accurate. When running the computer idle for about an hour and checking the battery level it seems that the battery have lost its former capacity leaving a smaller percentage of battery after an hour use.

    When checking the CPU voltage with core temp and the energy drain in wattage with the lenovo energy app, everything seems like before. That is about 14-18 watt drain for the entire computer according to the lenovo app, and core temp reports my CPU running at it's lowest state when idling.

    So my question is, has anyone else experienced this? The computer is about one year old and is running plugged in for about 95% of the time. Do I have a bad battery or is there any other known bug with the battery software?

    I'd do the full recalibration if you haven't. Just let it run overnight. See what happens.

    That seemed to have done the trick. Thanks for the hint!
