当我使用电池时，即使 CPU 负载为 100%，性能调节器也会选择 800Mhz 作为我的系统速度。我在联想 P51 上使用 Ubuntu 16.04。
我希望它能更积极地提高 CPU 频率。我该如何配置？

analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4294.55 ms.
hardware limits: 800 MHz - 3.80 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 800 MHz and 3.80 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
