PC Not Able To Enter Sleep

Hi, my HP Pavilion g4-1016dx Windows 7 x64 laptop is prevented from entering sleep due to:

Report from powercfg -requests

System Availability Requests:System Required Request
The device or driver has made a request to prevent the system from automatically entering sleep.

Is there an updated IDT driver after 6.10.6341.0 or another suggested solution?

Thanks.
