sure the battery pack is inserted correctly and securely. If the battery
falls out, while you are carrying the PC, you could be injured or the
battery pack could be damaged.

computer on battery power once a week until the battery pack is fully
discharged. Refer to the section
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 the 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.
