1. 电源管理基础概念<a href="https://geek-blogs.com/blog/arch-linux-power-management/#1-dian4-yuan2-guan3-li3-ji1-chu3-gai4-nian4">#</a>
</h2><p>在深入工具之前，需先理解 Linux 电源管理的核心概念：</p>
<ul>
<li>
<p><strong>电源状态</strong>：系统电源状态分为运行（Active）、挂起（Suspend，S3 模式，传统深度睡眠）、休眠（Hibernate，S4 模式，内存写入磁盘后断电）、混合睡眠（Hybrid Sleep，S3+S4，兼顾快速恢复与数据安全）。现代 Intel 平台还支持 S0ix（Low-Power Idle，低功耗活动状态），但需硬件与固件支持。</p>
</li>
<li>
<p><strong>CPU 调控器（Governor）</strong>：控制 CPU 频率动态调整策略，常见模式包括：</p>
<ul>
<li><code>powersave</code>：优先降低频率，节省电量；</li>
<li><code>performance</code>：维持最高频率，提升性能；</li>
<li><code>schedutil</code>（默认）：基于调度器负载动态调整，平衡性能与功耗；</li>
<li><code>ondemand</code>/<code>conservative</code>：根据负载阈值调整（较旧，逐步被 <code>schedutil</code> 取代）。</li>
</ul>
</li>
<li>
<p><strong>设备功耗</strong>：除 CPU 外，屏幕、Wi-Fi、蓝牙、硬盘/SSD、USB 设备等均为耗电大户，需针对性优化（如降低亮度、禁用闲置设备）。</p>
