Thinkpad T450s 有双电池。我的系统 (16.04) 可以看到它们两个，但输出如下acpi -V：
Battery 0: Unknown, 0%
Battery 1: Discharging, 11%, 00:10:12 remaining
Battery 1: design capacity 2177 mAh, last full capacity 1938 mAh = 89%
因此，它知道有两个。奇怪的是，upower -i数字是倒着的（BAT0 似乎已知，BAT1 似乎未知）。以下是 的输出upower -i /org/freedesktop/UPower/devices/battery_BAT0：

如果这是解决方案的话，我很乐意购买一块新电池，但我犹豫是否买了一块电池后才发现它没用……
答案1
我最终还是去买了一块新电池，而且它还能用！！所以，我猜这毕竟只是一块坏电池！
