Charging The Batteries; Procedures; Time - Toshiba Satellite M40 User Manual

Charging the batteries

When the power in the battery pack becomes low, the Battery indicator
flashes amber indicating that only a few minutes of battery power remain. If
you continue to use the computer while the Battery indicator flashes, the
computer enables Hibernation mode (so you don't lose data) and
automatically turns off.
The computer enters Hibernate mode only if Hibernation is enabled in two
places: the Hibernate tab in Power Options and Setup Action tab in
TOSHIBA Power Saver.
You must recharge a battery pack when it becomes discharged.

Procedures

To recharge a battery pack while it is installed in the computer, connect the
AC adaptor to the DC IN socket and plug the other end into a working
outlet.
The Battery indicator glows amber when the battery is being charged.
Use only the computer connected to an AC power source to charge the
battery pack. Do not attempt to charge the battery pack with any other
charger.

Time

The following table shows the approximate time required to fully charge a
discharged battery.

The charging time when the computer is on is affected by ambient
temperature, the temperature of the computer and how you use the
computer. If you make heavy use of external devices, for example, the
battery might scarcely charge at all during operation. Refer also to the
section Maximizing battery operating time.
