HP Compaq NC6320 Getting Started Manual page 22

First-time setup
It is recommended that you leave the computer connected to
external power until the battery pack is fully charged and the
battery light is turned off. (A partially charged new battery pack
can run the computer after software setup is complete, but battery
charge displays will not be accurate until the new battery pack has
been fully charged.)
✎
Power cords and AC outlets vary in appearance by region
and country.
