Connecting the AC adapter
You can run your convertible tablet PC using an AC adapter or your convertible
tablet PC’s battery. The battery was shipped to you partially charged. You should
use the AC adapter right away to fully charge the battery. Allow 24 hours for
the battery to fully charge.
To connect the AC adapter:
1 Connect the power cord to the AC adapter.
Important If the battery is not fully charged before you use your
convertible tablet PC on battery power for the first time, the
battery life may be much shorter than you expect. If the
battery life seems short even after being charged for
24 hours, the battery may need to be recalibrated. For
more information, see “Recalibrating the battery” on
page 158.
Warning Make sure that you use the AC adapter that came with
your convertible tablet PC or one of the same type
purchased from Gateway.
Replace the power cord if it becomes damaged. The
replacement cord must be of the same type and voltage
rating as the original cord or your convertible tablet PC
may be damaged.
