Toshiba TECRA M5 user manual Charging the batteries

Power and Power-Up Modes

Caution

1.Use only battery packs recommended by TOSHIBA as replacements.

2.When installing a battery pack or before moving the PC, always make 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.

3.Charge the battery pack only in an ambient temperature between 5 and 35 degrees Celsius. Otherwise, the electrolyte solution might leak, battery pack performance might deteriorate and the battery life might be shortened.

4.Never continue to use a battery pack after its recharging capability has become impaired, or after the warning message indicating that the battery pack power is exhausted has been displayed.

5.Continued use of an exhausted or impaired battery pack could result in the loss of data or damage to PC.

6.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 is in 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 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.

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.

The computer enters Hibernate mode only if Hibernation is enabled in two places: the Hibernate tab in Power Options and Setup Actions tab in TOSHIBA Power Saver.

You must recharge a battery pack when it becomes discharged.
