背景： 我带着我的旧 Chromebook（华硕 C200-MA），并设法安装了 Xubuntu（24.04.2 LTS，内核 6.8.0-55-generic）作为唯一的操作系统。（感谢 mrchromebox.tech）。我很确定 ChromeOS 上的电池没问题。

问题： 即使识别到电池，也无法充电。拔掉充电线后立即关机。

信息:

  • 我没有这个文件（并且无法创建它）：
- /sys/class/power_supply/BAT0/charge_control_start_threshold
- /sys/class/power_supply/BAT0/charge_control_end_threshold
  • 结果upower -i $(upower -e | grep BAT)：
  native-path:          BAT0
  vendor:               AS19IUD
  model:                C200-42
  power supply:         yes

  • 结果acpi -V：
Battery 0: design capacity 4240 mAh, last full capacity -42 mAh = -1%
Adapter 0: on-line
Cooling 0: Processor 0 of 10
Cooling 1: soc_dts1 no state information available
Cooling 2: intel_powerclamp 0 of 100
Cooling 3: soc_dts0 no state information available
Cooling 4: Processor 0 of 10
  • info tlp cmd 的结果tlp-stat -b：

  • 我的 BIOS 中没有任何选项可以启用/禁用电池

  • 电源管理图片：

  • 有什么想法我可以尝试吗？

编辑：

cat /sys/class/power_supply/BAT0/voltage_now 
5763000
cat /sys/class/power_supply/BAT0/voltage_min_design 
11400000

-> 可能是电池或充电器没电了？（插入交流电时工作）

多谢 ：）
