After a clean install of Windows 7 Home 64 bit, I have 2 missing drivers.
Unknown device: ACPI/VPC2004
PCI Simple communications controller
System: Lenovo B50-80
any help to find these missing drivers is welcome. I can not find these on the website or in downloads.

Actually, i am having the same problem.
After installing all drivers from the lenovo website, i still have the ACPI/VPC2004 as unknown device.
I will try the link posted by neokenchi for sure.
Could you guys please tell me the full product number of your laptops?
(mine btw is 80EW0192IX )
