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 battery power consumption. You can activate the
dust cleaning feature by touching and holding the touch-sensitive button for
three seconds. The icon
seconds and 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.
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.
• You can cancel dust cleaning at any time by touching the touch-sensitive button when it is
flashing.
