1237 adjacent levels often map to the same fan speed. 7 is the highest
1238 level, where the fan reaches the maximum recommended speed.
1243 There is also a "full-speed" level, also known as "disengaged" level.
1244 In this level, the EC disables the speed-locked closed-loop fan control,
1248 The fan usually ramps up or down slowly from one speed to another, and
1250 commands. The full-speed level may take up to two minutes to ramp up to
1251 maximum speed, and in some ThinkPads, the tachometer readings go stale
