Activating dust cleaning feature
Dust tends to build up around the heat-sink of a computer’s CPU over time.
Accumulated dust can reduce the dissipation capability of a heat-sink,
resulting in an increase in batter power consumption. You can activate the
dust cleaning feature by touching and holding the touch-sensitive button for
three seconds. The touch-sensitive button will flash, indicating that the dust
cleaning feature has been activated. The fan will spin at high speed and then
stop alternately for about two minutes to discharge the accumulated dust.
Upon completion of dust cleaning, the computer will revert back to the
previously-selected mode.
Energy Management button
Lenovo Energy Management provides you control over the performance and
power consumption for each component of your notebook through the
collaboration of software and hardware, thus extends battery life and
improves battery runtime.
Notes:
•
When using the dust cleaning feature, make sure your computer is placed in a clean work
area with good ventilation.
•
We recommend that you perform dust cleaning at least once a month to prevent dust
accumulation.
