如何改进 Zenbook UX303UA 的电源管理?

情况:当我需要计算能力时,特别是当 zenbook 处于交流电时,为了改善 zenbook 的电源管理,
我正在试验大约 3 小时的电池寿命,没有任何计算,没有任何固件故障/问题,只需在我的新计算机中输入 Stackexchange 网络UX303UA。预计电池使用时间长达 7 小时,这里它的华硕网站。 Arch Linux wiki 确认同系列超极本

电池设计容量为4429mAh,在正常情况下(平均负载约为0.3,启用WiFi,亮度降至中等范围),无需进行严重的省电调整,即可提供3小时多一点的续航时间。 - - ACPI 工具能够正确检测电池状态。

他们推荐笔记本电脑模式工具,我将要测试

  1. apt-get install laptop-mode-tools
  2. Enable laptop-mode.service,其中以下命令应返回2

    cat /proc/sys/vm/laptop_mode
    
  3. 实际上,我不明白为什么他们建议将笔记本电脑模式改为1我想0在交流电下保持的模式,因为我需要电力进行计算

    # http://askubuntu.com/questions/180712/how-to-enable-laptop-mode
    # edit /etc/laptop-mode/laptop-mode.conf`       
    ENABLE_LAPTOP_MODE_ON_AC=1 
    # where I want to have zero. Why they propose 1?
    
  4. laptop-mode以 root 身份重新启动/etc/init.d/laptop-mode restart

grep-命令找到的默认省电状态

我不确定目录中哪些文件与电源管理相关etc/laptop-mode/conf.d/,等等许多作者忽略ac97-powersave.conf- - 为什么?

迭代 GAD3R 的答案

安装软件包 ( apt-get install laptop-mode-tools)、重新启动并仅使用默认电源选项会显着增加电池使用时间。现在,25% 的电池电量大约需要 2 小时 15 分钟,因此 100% 的电池电量大约需要 10 小时的使用时间,即大约 3.5 倍的电池使用时间。设置文件中只有几个选项被关闭,我找不到任何与打开相关的选项

root@masi:/home/masi# grep =0 /etc/laptop-mode/laptop-mode.conf
#    CONTROL_something=0/1   Determines whether Laptop Mode Tools controls 
VERBOSE_OUTPUT=0
DEBUG=0
ENABLE_LAPTOP_MODE_ON_AC=0
ENABLE_LAPTOP_MODE_WHEN_LID_CLOSED=0
DISABLE_BATTERY_ALARM_CHECK=0
CONTROL_NOATIME=0
CONTROL_HD_WRITECACHE=0
NOLM_BATT_HD_WRITECACHE=0
LM_HD_WRITECACHE=0

我不想改变默认值太多。您将更改哪些设置来实现电源管理的显着改进?

硬件:华硕 Zenbook UX303UA
操作系统:Debian 8.5 64 位
固件:按照线程中的描述更新和/或安装在 Debian 8.5 中升级 Linux 内核有多顺利?
Linux 内核:向后移植 4.6
相关:华硕 Zenbook UX303在 Arch Linux
其他第二代华硕 Zenbook 中:UX301LA

答案1

要改进笔记本电脑上的电源管理,请/etc/laptop-mode/laptop-mode.conf通过运行以下命令从 GUI 或使用 GUI 启用 LMT 的所有功能:gksu lmt-config-gui

许多作者忽略 ac97-powersave.conf - - 为什么?

这个功能很有用,只有当你有AC97声卡时,你可以通过文件启用它ac97-powersave.conf

nano /etc/laptop-mode/conf.d/ac97-powersave.conf

设置值如下:

# Control AC97 audio chipset power?
CONTROL_AC97_POWER=1
