Power and Power-up Modes
for procedures. If the computer is continuously operated on AC power
for an extended period, more than a month, the battery might fail to
retain a charge. It might not function efficiently over the expected life
of the battery pack and DC IN/Battery indicator might not indicate a
low-battery condition.
3. After the battery pack is charged, avoid leaving the AC adaptor con-
nected 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 DC IN/Battery
indicator flashes amber indicating that only a few minutes of battery power
remain. If you continue to use the computer while the DC IN/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 DC IN/Battery indicator glows amber when the battery is being
charged.
Time
The following table shows the approximate time required to fully charge a
discharged battery.
Charging time (hours)
Use only the computer connected to an AC power source or the optional
TOSHIBA Batteries charger to charge the battery pack. Never attempt to
charge the battery pack with any other charger.
Battery type Power on Power off
Battery pack (3 cell) 8 hours or more 2.5 hours
Battery pack (6 cell) 8 hours or more 3.8 hours
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.
