Calibrate battery
Hi
This is a HP 6720s notebook. I'm having problems with my battery.
The percentage indicator is not accurate.
It randomly hibernates below 40%. It's only supposed to do that when it's on 5%. It's supposed to give a "low battery" warning on 10% but it never does that.
Do I need to calibrate the battery? If so what's the best method to do that? Do I need to run it until it's completely empty?
