Hi, 
Whole CPU frequency managment is broken somehow.
i5-4200U CPU @ 1.60GHz CPU should support 800 Mhz, But i see it's running at
least on 1.6 Ghz. (After suspend/resume It's running in Turbo mode)

bio@dell-xps:/sys/devices/system/cpu/intel_pstate$ cpufreq-info
cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
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: 0.97 ms.
  hardware limits: 800 MHz - 2.60 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 800 MHz and 2.60 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
