Power
• Use only the Dell-provided AC adapter approved for use with this computer. Use of
another AC adapter may cause a fire or explosion.
• Before you connect the computer to an electrical outlet, check the AC adapter
voltage rating to ensure that the required voltage and frequency match the available
power source.
• To remove the computer from all power sources, turn the computer off, disconnect the
AC adapter from the electrical outlet, and remove any battery installed in the battery bay
or module bay.
• To help prevent electric shock, plug the AC adapter and device power cables into
properly grounded power sources. These power cables may be equipped with 3-prong
plugs to provide an earth grounding connection. Do not use adapter plugs or remove
the grounding prong from the power cable plug. If you use a power extension cable,
use the appropriate type, 2-prong or 3-prong, to mate with the AC adapter power cable.
