When you choose to completely format the disk to install only Linux, does the installation delete also the drivers of the hardware? Recently I installed Linux Mint in an HP and after the installation it says that the battery is not HP anymore.
The tool that is reporting that may be inspecting the actual manufacturer of the battery. For example, in my laptop (a Lenovo ThinkPad), the battery is not reported as Lenovo's, but as SMP as they are its actual manufacturer:Recently I installed Linux Mint in an HP and after the installation it says that the battery is not HP anymore.
