Win 7 - Hidden properties of power management and weird performance

windows windows-7 power

Solution 1:

Well, the phenomenal guys at Dell support got this solved for me! It had to do with the explicit order in which the drivers are installed. To potentially save someone else the same headache, I'm posting it here (for my config):

  • Dell Intel HM77 Panther Point Chipset
  • Dell Intel Management Engine Interface
  • USB 3.0
  • Media Card Reader
  • Intel Ivy Bridge HD Graphics
  • Video Card Drivers
  • Intel Wireless Display 3.0 (Optional) More Information
  • Dell Atheros AR8151
  • Dell Intel Centrino Wireless-N
  • Dell Intel Centrino Wireless-N 2230 Bluetooth
  • Sound Blaster Recon3Di
  • ST Microelectronics DE351DL Free Fall Sensor
  • Synaptics Touchpad
  • Command Center
  • On Screen Display Application

Good luck all!
