Windows 7 on Y530, can't find driver for ACPI\VPC2004 unknown device

2010-10-11, 8:52 AM

I purchased Windows 7 Home Premium 64bit from Lenovo and did a fresh install on my Y530.  After adding every possible Windows 7 driver from http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_list.aspx?CategoryID=13 I still see one Unknown Device in the Device Manager.  The device is identified as ACPI\VPC2004.  I guess that's a power management device, and the driver's name is "ATK ACPI driver".  I downloaded it from http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_show_2864.html .

 

After installing the "ATK ACPI driver" I reboot and still see the unknown device, ACPI\VPC2004.  Is there a driver that works for the ACPI\VPC2004 device?

Thanks, that worked.

I wonder why Lenovo didn't put that important link on the Y530 downloads page? It would have saved me an hour or two of googling and reading forums.
