Be aware that the charging time when the computer is on is affected
by ambient temperature, the temperature of the computer and how
you are using the computer. If you make heavy use of external
devices for example, the battery might scarcely charge at all during
operation.
Note that charging time will vary depending on the ambient
temperature, the computer's internal temperature, and how the
computer is being used. For example, whether the display is set to
shut off automatically when idle, whether you make heavy use of
external devices powered by the computer, or if the computer's
internal storage drive is being accessed frequently by an application.
Charging notice
The battery might not begin charging immediately under the following
conditions:

capacity, charge it at room temperature of between 5°C to 35°C (41°F
to 95°F).
The battery is nearly completely discharged. In this instance, leave the
AC adaptor connected for a few minutes and the battery should begin
charging.
