我Lenovo ThinkPad T61
的电池相当旧,几年前,由于旧电池没电了,我不得不更换电池。现在更换电池似乎快要死了,但是我从那里得到了相互矛盾的数据xfce4-power-manager
。所以我想知道是否有一种方法可以检查电池是否健康。
症状如下:
- 电源管理器指示
battery is fully charged
- 如果我断开交流充电器的连接,则电池状态会
47%
在不到5分钟的时间内跳到或类似的状态 - 在不到15分钟的时间里,笔记本电脑的果汁用完了,然后关机
我试图检查upower
数据:

我还查看了ACPI

但我不能找出任何可疑:在design capacity

似乎健康的我。
那么,还有其他实用程序可以指示电池是否按预期工作,或者是否需要更换?
cycle count: 0
指示?传感器不报告此信息?
