Power and Power-Up Modes
7. Never install or remove the battery pack without first turning off the
power and disconnecting the AC adaptor. Never remove the battery
pack while the computer in Suspend or Standby mode. Data will be lost.
Note
1. Never remove the battery pack while the Wake-up on LAN function is
enabled. Data will be lost. Before you remove a battery pack, disable
the Wake-up on LAN function.
2. To ensure the battery pack maintains maximum capacity, operate the
computer on battery power once a week until the battery pack is fully
discharged. Refer to the section Extending battery life in this chapter for
procedures. If the computer is continuously operated on AC power for
an extended period, more than a week, the battery might fail to retain a
charge. It might not function efficiently over the expected life of the
battery pack and Battery indicator might not indicate a low-battery
condition.
3. After the battery pack is charged, avoid leaving the AC adaptor
connected and the computer turned off for more than a few hours at a
time. Continuing to charge a fully-charged battery pack can damage the
battery.
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.
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.
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.
Use only the computer connected to an AC power source or charge the
battery pack. Do not attempt to charge the battery pack with any other
charger.
