Cleaning procedures

Keeping your computer system free of dust, dirt, and heat will prolong its life.

●Dust, pet hair, and other particles can build up, creating a blanket effect; as a result, components can overheat or, in the case of the keyboard and mouse, not work smoothly and effectively.

●Check your system once a month for visible signs of dust and debris, and clean it about once every three months.

●Visit www.hp.com/support for additional cleaning instructions.
