笔记本电脑电池电量未从 59% 上升（即显示错误的电池统计信息）

我在 Lenovo z500 上使用 Linux Mint-17.2。我修复了 Nvidia GPU 问题（成功安装了 bbswitch），还修复了屏幕背光问题，所以只剩下电池问题了。电量指示灯不卡住；当我拔掉电源线时，它的电量就会减少，但它只充到 59%，而且无法继续充电。

因此，为了回答我的问题，这就是我所做的，双启动 Windows，然后安装联想能源管理，将电池设置更改为“最大电池寿命”。在“优化电池健康状况”中充电被锁定为60%，60%后将显示已插入，未充电

对于那些不想双启动 Windows 的人

非常不幸的是，充电阈值是特定于固件和供应商的。

幸运的是，联想用户获得了 ThinkWiki 上概述的解决方案。

它基本上表示您必须安装并加载 tp_smapi 内核模块：

git clone https://github.com/teleshoes/tpacpi-bat.git
cd tpacpi-bat/
./install.pl

并写入所需的充电阈值

sudo ./tpacpi-bat -s ST 1 15 # load internal battery when below 15%
sudo ./tpacpi-bat -s SP 1 95 # stop charging at 95%
sudo ./tpacpi-bat -g ST 2 # when is external battery loaded?

然后当电量达到95%时就会停止充电，只有当电量低于15%时才开始充电

作为参考，我在 debian 和 Linux Mint 测试中做了这个，但我确信它在 ubuntu 中也同样有效。
