节省电池电量

执行以下操作来节省电池电量。

只要可能,请将计算机连接到电源插座上,因为电池的寿命很大程度上取决于电池被使用和充电 的次数。

当长期不使用计算机时,将计算机置于待机模式或休眠模式。请参阅 《用户指南》中的 电源 管理模式以获得有关待机和休眠模式的信息。

使用 电源管理向导来选择选项以优化您的计算机电源使用。当按电源按钮、关闭显示屏或按 <Fn><Esc> 组合键时,这些选项也可被设置为变更。请参阅 《用户指南》中的 配置电源管 理设置以获得有关使用 电源管理向导的信息。

为电池充电

: 使用 Dell™ ExpressCharge™ ,当计算机被关闭时,交流适配器将一个电量完全消耗的电池在大约 1 个小时内充到 80% 电量,在大约 2 个小时内充到 100% 电量。在开启计算机的情况下,充电时间会较长。 将电池留在计算机中的时间可以随意而定。电池的内部电路可防止电池过量充电。

当将计算机连接到电源插座或者在计算机已连接到电源插座的情况下安装电池时,计算机会检查电 池的电量和温度。如有必要,交流适配器将为电池充电并维持电池电量。

如果电池因计算机使用而变烫或者正处于高温环境中,则当您将计算机连接到电源插座时电池可能 不会充电。如果 指示灯以桔黄色和绿色交替闪烁,则表示由于电池过热而无法开始充电。将计 算机与电源插座断开并使计算机和电池冷却到室温。然后,再将计算机连接到电源插座继续为电池 充电。

更换电池

警告 : 在执行这些程序之前,关闭计算机,断开交流适配器与电源插座和计算机的连接,断开调制解调 器与壁装连接器和计算机的连接,然后将任何其它外部电缆从计算机上卸下。

注意 : 您必须将所有外部电缆从计算机上卸下以避免对连接器造成可能的损坏。

警告 : 使用不兼容的电池可能会增加起火或爆炸的危险。请仅使用从 Dell 购买的兼容电池来更换旧电 池。电池设计用于您的 Dell ™ 计算机。请勿将其它计算机的电池用于您的计算机。

卸下电池:

1如果计算机已连接至对接设备 (已对接),请断开对接。有关说明,请参阅您的对接设备随附的 说明文件。

2请确保已关闭计算机。

3滑动和按住计算机底部上的电池槽释放闩锁,然后将电池从电池槽中提起。
