I use Ubuntu 18.04LTS dual boot with Windows 7. When I plug charger while using Ubuntu it shows fully charged and I unplug charger, battery level is on 94%. But when I boot Windows 7, and when battery fully charged, Windows shows 100%.



I have searched a lot about this problem, but could not find a solution for this problem.



Additionally, I have updated my laptop BIOS to the latest version.



How can I solve this?



Laptop is Hp ProBook 450 G2






dual-boot 18.04 windows power-management battery
