我遇到了一个非常烦人的问题：全新华硕 TUF FX506 的电池续航时间大约为 1 小时 10 分钟。
已安装 TLP，底部附有 tlp-stat 输出。抱歉信息太长，但我认为提供足够的信息是积极的。
我不是一位有经验的用户，也不具备了解后台可能出现的问题的技能。调整 TLP 似乎对电池行为没有任何影响。
如果有人能给我指明正确的方向的话？
感谢致敬，
卡洛斯。

答案1
您的笔记本电脑（很可能）具有 Nvidia Optimus 混合显卡，并且您似乎已经安装了专有驱动程序。
我建议两点：
a. 启用 TLP PPA 以获取最新版本（请参阅文档)：
sudo add-apt-repository ppa:linrunner/tlp
sudo apt update
sudo apt install tlp tlp-rdw
b. 从常问问题：
步骤 1：为 GPU 驱动程序启用运行时电源管理
从黑名单中删除所有 GPU 驱动程序，只留下
RUNTIME_PM_DRIVER_BLACKLIST="mei_me"
提示：为此你必须更改配置文件/etc/tlp.conf，记得删除前导#
然后使用以下方法应用更改的设置
sudo tlp start
预期结果：GPU 处于空闲状态时将自动暂停（关闭电源）。
步骤 2a：切换到 iGPU - 具有专有驱动程序和设置工具的 Nvidia Optimus
启动 nvidia-settings，转到 PRIME Profiles，选择 Intel（省电模式）。再次登录（或重新启动）。
结果：屏幕内容的渲染转移到 iGPU，将 dGPU 置于空闲状态，从而允许运行时电源管理关闭 dGPU（参见步骤 1）。
编辑：步骤 2a 可能与 AMD Ryzen CPU 不同。我很想了解其中的区别。
