电量表

通过按一次或按住电池上电量表的状态按钮,可以检查:

电池电量 (通过按压然后释放状态按钮来检查)

电池性能状态 (通过按压并按住状态按钮来检查)

电池使用时间在很大程度上取决于充电次数。在经过数百次的反复充电和放电之后,电池的蓄电量

或电池的性能状态会有所下降。也就是说,电池可以显示 电量充足的状态,但是充电能力 (性能)降低。

检查电池电量

要检查电池电量,按压然后释放电池电量表上的状态按钮以点亮充电级别指示灯。每个指示灯代表 约百分之二十的电池总电量。 例如,如果电池剩余百分之八十的电量,则会亮起四个指示灯。如果 没有指示灯亮起,则表示电池电量已耗尽。

检查电池性能状态

: 您可用下列两种方式之一来检查电池性能状态:使用如下文描述的电池上的电量表,或使用 Dell QuickSet 中的电池表。有关 QuickSet 的信息,在任务栏中的 QuickSet 图标上单击鼠标右键,然后单击 Help (帮助)。

要使用电量表检查电池的性能状态,请按住电池电量表上的状态按钮至少 3 秒钟。如果未出现任何 指示灯,则表明电池状况良好,并且其原始蓄电量仍保持在百分之八十以上。 每个指示灯均代表 电量的递减。如果显示五个指示灯,则表明电池的蓄电量剩下不足百分之六十,此时应考虑更换电 池。 有关电池使用时间的详细信息,请参阅 《用户指南》中的 规格

电池低电量警告

注意 : 为避免丢失或损坏数据,请在出现电池低电量警告后立即保存您的工作,然后将计算机连接到电 源插座。 如果电池的电量耗尽,计算机则会自动进入休眠模式。

默认设置是,当电池电量消耗达到约百分之九十时,屏幕上将显示弹出式窗口警告。您可以在 QuickSet Power Options Properties (电源选项属性)窗口中更改用于电池警报的设置。有关访

QuickSet Power Options Properties (电源选项属性)窗口的信息,请参阅您的 《用户指南》 中的 配置电源管理设置
