联想IdeaPad L3 15IML05（Arch Linux系统）切换CPU性能调控器时出现电流噪音求助

各位大佬好，我碰到个有点烦的小问题，想请教下大家：

我用的是联想IdeaPad L3 15IML05笔记本，装的是Arch Linux系统。先给大家贴一下我当前CPU驱动的状态信息，通过cpupower frequency-info命令查询的结果如下：

~  λ  cpupower frequency-info
driver: intel_pstate
CPUs which run at the same hardware frequency: 3
CPUs which need to have their frequency coordinated by software: 3
maximum transition latency:  Cannot determine or is not supported.
hardware limits: 400 MHz - 4.90 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 400 MHz and 4.90 GHz.
                The governor "powersave" may decide which speed to use
                within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 2.12 GHz (asserted by call to kernel)
boost state support:
  Supported: yes
  Active: yes

我的问题是，当我执行cpupower frequency-set -g performance命令把CPU调控器切换到performance模式时，笔记本会发出电流噪音。这个噪音很微弱，持续存在...
