    Does anyone have Windows 7 and sleep works? If so can you go into your bios, advanced and see if you have Intel Virtualization Tech enabled and Intel VT-d enabled?

    If so let me know, if not please enable these and tell me if your sleep still works?

    Mine works only with VT-d off.

    Vista worked fine.

    These setting wont hurt your system at all so dont worry on that part. They are to help run virtual machines better... Which I use, but I also use sleep :(

    I am running bios 213

    You can leave VT-d off. You only need VT-x ("Intel Virtualization Tech" in the BIOS) turned on for hardware support of virtualized OS guests.

    VT-d is used for hardware pass through which is probably useless for most people unless you're using Xen or something similar for virtualization and you're needing to pass a PCI or PCI Express device directly to a guest OS...

    Even VMWare doesn't require VT-d to pass USB devices to guest OS'es. VT-d is for lower-level pass through (primarily used for SCSI or SAS SATA RAID controllers and to a certain degree, PCI DVB cards, TV tuners, PCI Video Card, etc).

    Cheers,

    Yea, I know VM's work without that enabled but it does help things run better due to the more direct access items get.

    But can anyone confirm this is indeed an issue and not just me? :)

    confirmed, i have the exact same issue on a G50vt-a1 and Win7 Ultimate

    it would be great if we could find a solution, VT-d can be nice when using Virtualbox :)

    it seems this is a widely known issue, not only affecting Asus notebooks

    virtualization is either disabled after standby, or our problem appears - it was mentioned that both Intel and Asus are working on it, but no idea about the results (if any)

    I'm sorry for bringing this post back from forever ago but THANKS guys you saved me from a reformat. Which wouldn't have fixed anything.

    In addition: does anyone know if there is a fix for this?

    Haha, this Asus was my fix from a lower-end Sager. I suspect their high-end stuff is better.
