How to:1. Hit the start menu, and type "regedit" (Registry editor). Run it as an administrator to gain the needed privileges.
2. From the left side folder tree, navigate to the following key.
HKLM stands for HK_Local_Machine3. Navigate to " Device Parameters "
4. Change the following DWORD values from 1 to 0
AllowIdleIrpInD3, DeviceSelectiveSuspended, EnhancedPowerManagementEnabled, SelectiveSuspendEnabled
5. Do this for every sub folder inside " VID_1B1C&PID_0C04 ". In my case, it's just one folder.
6. Restart your machine.
After restarting, you will notice that the missing LED controls and fan controls are visible again.
