[. . . ] Never remove the battery pack while the Wake-up on LAN function is enabled. Before you remove a battery pack, disable the Wake-up on LAN function. 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 the Battery indicator might not indicate a lowbattery condition. 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 orange 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 orange when the battery is being charged. Use only the computer connected to an AC power source or the optional TOSHIBA Battery charger to charge the battery pack. Do not attempt to charge the battery pack with any other charger. Satellite 2430 Series 6-7 Power and Power-Up Modes Time The following table shows the time required to fully charge a discharged battery. Charging time (hours) Battery type Battery pack RTC battery Power on 3. 5 to 12 or longer about 24 Power off about 3. 5 about 24 with AC or Battery pack 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 Maximising battery operating time. The same factors affect charge time. Battery charging notice The battery may not charge right away under the following conditions: The battery is extremely hot or cold. To make sure the battery charges to its full capacity, charge the battery at room temperature of 10° to 30°C (50° to 88°F). The battery is nearly completely discharged. Leave the AC adaptor connected for a few minutes and the battery should begin charging. Once a battery pack is fully charged, it is recommended that you operate the computer only on battery power until the battery pack completely discharges. Doing so extends battery life and helps ensure accurate monitoring of battery capacity. [. . . ] serial: The handling of data bits one after the other.
