95 - Caring for your LifeBook Notebook
Disinfecting LifeBook computers
Wipe the surface with a soft cloth wipe and a 50% ethanol solution or use another ethanol-based germicide 
which has been registered as a hospital disinfectant by the EPA.
Cleaning the dust filter
Your LifeBook is equipped with fans to make air flow inside by pulling in outside air to cool the inside of 
the system. Depending on the environment in which the system is used, dust and dirt may be pulled in 
along with the air. Accumulated dust and dirt could impair the function of the system. 
1
Turn off your computer and disconnect the AC adapter.
2
Close the display panel and turn the system upside down. 
3
Remove the dust filter by pressing the latch towards the filter and lifting it out (Figure 38).
4
Carefully clean the dust filter and the air-cooling duct.
