Cleaning The Notebook - Fujitsu Lifebook U939X Operating Manual

Cleaning the notebook

Do not clean any interior parts yourself; leave this job to a service technician.
Only use cleaning products designed for computers. Normal household
cleaners and polishes can damage the markings on the keyboard and the
device, the paintwork or the notebook itself.
Ensure that no liquid enters the notebook.
The LCD screen is very sensitive to scratches. Only clean the display
surface with a very soft, slightly damp cloth.
► Switch the notebook off.
