Cleaning the optional dust lter
Some models are equipped with a front bezel that includes a dust lter. You must periodically clean the dust
lter so that the dust collected on the lter does not impede air ow through the computer.
NOTE: The optional dust lter front bezel is available from HP.
To remove, clean, and replace the dust lter:
1. Turn o the computer properly through the operating system, and turn o any external devices.
2. Disconnect the power cord from the AC outlet and disconnect any external devices.
IMPORTANT: Regardless of the power state, voltage is always present on the system board as long as
the system is plugged into an active AC outlet. To prevent damage to internal components, you must
disconnect the power cord from the power source before opening the computer.
