电池充电量停留在 60%

我有一台联想 Z500 笔记本电脑，最近从 Win7 迁移过来，我使用联想实用程序将电池充电至 60%（据说这会延长其使用寿命）。

但是安装 Ubuntu 后，设置仍然适用，电池无法充电超过 60%，我找不到办法更改它，以便将电池充满电。任何帮助都将不胜感激。

答案1

要从 Linux 管理保护模式，有一个 gnome 扩展可以进行监控和切换（就像 Windows 上的 Lenovo vintage 一样）

点击这里

还有一种手动方法

::::::::: 保守模式命令 ::::::::

从终端

sudo su

写密码

读取当前状态：

cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode

启用保护模式：

echo 1  >  /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode

禁用保护模式：

echo 0  > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode

答案2

看看电池是否被篡改了。安装TLP工具。

sudo add-apt-repository ppa:linrunner/tlp 
sudo apt-get update
sudo apt-get install tlp tlp-rdw

然后运行：

sudo tlp start

启动服务然后

sudo tlp stat

获取电池的具体信息。

向我们提供该输出，特别是最后的 CAPACITY 参数。

答案3

根据 karim samir 的建议，我尝试了一下并成功，但做了一些小的改动来解决我在执行命令时遇到的一些权限被拒绝错误。

我使用的是联想 Yoga 2 13，运行的是 Ubuntu 21.10。电池电量卡在 59%。现在电量完美充至 100%。

我使用的命令是：

检查电池节能状态： 

cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode

Result: 0 = disabled, 1= enabled

禁用电池节能模式：

sudo bash -c 'echo 0 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode'

启用电池节能模式：

sudo bash -c 'echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode'

基本上，我插入了 [sudo bash -c] 并用“和”包裹了 Karim 的命令。

答案4

对于戴尔，它位于 BIOS 中。主要充电配置我可以选择电池在达到一定百分比时开始和停止充电。这将立即应用于 PC 上的所有操作系统。

我相信您的 BIOS 中也一定有类似的东西，Windows 实用程序应该通过直接写入此设置来更改它。因此，请耐心查看 BIOS 中的所有选项并找到此设置。
