      All Win: Processor works at half speed - IdeaPad / IdeaCentre

      Symptom:

      System information and diagnostics tools tell that processor works at half of speed.

      SOLUTION:

      This is a designed feature for all laptops having Intel Speed Step feature (currently - all Atom and Core 2 Duo-based processors except Celeron series). Processor will run at full speed only if heavy task is launched. If customer complains that even heavy tasks do not enable full speed of CPU, then Energy Management settings should be checked - some profiles have lowest CU speed enabled by default with no option to rise it until profile settings are changed. This is designed for power saving purposes.
