Charging The Batteries - Toshiba L40 Series User Manual

6. Be sure to monitor the remaining battery power. If the battery pack or
real time clock battery discharge completely, Sleep Mode will not
function, data in memory will be lost, and the computer might register
an incorrect time and date. In this case, connect the AC adapter to
recharge the batteries.
7. DO NOT install or remove the battery pack without first turning off the
power and disconnecting the AC adapter. DO NOT remove the battery
pack while the computer is in Sleep Mode as data will be lost.
Note
1. DO NOT remove the battery pack while the Wake-up on LAN function is
enabled as data will be lost. Disable the Wake-up on LAN function
before you remove the battery pack.
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
procedures. If the computer is continuously operated on AC power for
an extended period or for 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 the Battery indicator might not indicate a low-
battery condition.
3. After the battery pack is charged, avoid leaving the AC adapter
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
blinks amber indicating that the battery capacity is below 10%. If you
continue to use the computer while the Battery indicator blinks, the
computer enables Hibernation mode (so you do not 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 adapter 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.
