Unknown Device - Y730

When I go into Device manager I have an unknow device.  Microsoft ACPI Compliant Embedded Controller

If I go to Details it says:

ACPI\VPC2004

*VPC2004

If anyone knows where to get this driver(VISTA) I would appreciate it.

Re: Unknown Device - Y730

You should install ACPI driver and EnergyCUt (Energy Management) software.

Re: Unknown Device - Y730

Energy Management is installed (according to programs and features).  Whats weird is I downloaded it from lenovo and when I go to install again it says its trying to install an older version.  It says setup has detected that version 3.02.000 of Energy Management is already installed.  This setup installs an eariler version of Energy Management (3.1.5.3)

Where do I get the ACPI driver.  Do you have link because I do not see it on lenovo's website.

 

 

Thanks.

Re: Unknown Device - Y730

It also can be remote CIR (remote controller) , Halo Lightning or Second Display controller. Also try Energy Cut version that is on same page as others driversI mentioned.

Try here.

You also should try Y530 ACPI driver and ATK hotkey driver for Y530.

Re: Unknown Device - Y730

Wait, which version of Vista do you have? 32bit or 64? If 64 - try Y650 drivers.

Re: Unknown Device - Y730

That's extremely strange...

Uninstall EnergyCut and get one from Y510 - though it is old it might help.

Your device is definately what EnergyCut installs.
