Important web page, if you are installing #Linux on a notebook and features for power management are not recognised by the BIOS or UEFI at system startup.
It's a workaround that allows the kernel to describe itself as a Windows version in order to enable core ACPI functions that are otherwise disabled and often cause problems for suspend, resume, and embedded Wifi, Bluetooth, and other devices.
