Ubuntu 19.04 上電池始終顯示“估計”

Question

使用 Ubuntu 已經一年多了，沒有任何問題，幾天以來我的電池狀態有點奇怪。它總是顯示 100%，當我插入充電時，它顯示“估計”，當我拔掉充電器或插入時，它仍然如此。

以下命令顯示以下結果，

~$ upower -i /org/freedesktop/UPower/devices/battery_BAT0   native-path:          (null)   power supply:         no   updated:     Do 01 Jan 1970 01:00:00 CET (1561282273 seconds ago)   has history:    no   has statistics:       no   unknown
    warning-level:       unknown
    battery-level:       unknown
    icon-name:          '(null)'

acpi -V 顯示以下結果，

~$ acpi -V

sudo tlp-stat -b

知道發生了什麼事嗎？
