These values don't always make a whole lot of sense, but some users like to modify them to keep their fans quiet at all costs. Reading from this file will show the current performance level. Writing to the file can change this value. Valid options: "silent" "normal" "overclock" Note that not all laptops support all of these options. Specifically, not all support the "overclock" option, and it's still unknown if this value even changes anything, other than making the user feel a bit better.
