Is there a way possible to run a laptop only on AC power without having the need to remove the battery i.e. to disable the charging as it is possible in Windows 7.
I think the only way this is possible would be on a hardware level. I've never heard of a laptop that had this as an option, though.
In Windows that is probably done by a driver for this purpose. Something like Smart Battery in DELL laptops. Not sure if that will be an option for your laptop, check the builder's website.
