Upgrading to Pro doesn't automatically mean that Pro is activated, if there is a previously established hwid for pro it will be activated after the upgrade, if not, then you need to activate it by KMS_VL_ALL or google for massgravel and use it to generate a new hwid for pro.
Don't know about this version, but the driver that I've posted earlier here from the official Nvidia Developer website, that's the DCH version for sure.
When battery does not work properly then when booting you have a warning message from bios as date and time have been reset and that is not the case
