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.
The battery might not be charged depending on how the computer is
being used, and the charge of battery decreases and battery might not
be fully charged sometimes.
If the AC adaptor is connected via USB Type-C™ adapter, battery
charging time might become longer.
