    Hello.I have a problem with my laptop .i am running windows 10 and it shows wrong percentage of battery power.From 100%to 9% it takes around half an hour and then it stays stucked at 9% for about 3 hours and from 9% until 2% another hour.Then it powers off.How can i calibrate the percentage to be correct.?

    Also the design capacity of the battery is shown to be 72Wh but fully charged capacity is shown to be only 17Wh.
