z710 problem root\LenovoVhid

2014-07-16, 20:50 PM

Hi,

 

I have installed win7 x64 on my z710 and installed all the drivers I found on the support page. I still have an unknown device in my device manager. Name is root\LenovoVhid. It seems it came when I installed the Lenovo Energy Manager. Tried to uninstall and install again, didn't changed a thing.

Device manager also tells me that Lenovo ACPI-Compliant Virtual Power Controller driver is missing or damaged

 

Help me please

Hi hellvetik89,

 

I was having the exact same problem using Windows 7 Ultimate 64bit on a Lenovo Z710 that I got from Staples.  After searching far and wide, by fluke I came across this link:  http://support.lenovo.com/in/hi/downloads/ds030145 Low and behold, after installing and restarting both unknown devices (root/lenovoVhid & acpi\vpc2004) are now installed properly and seem to be working flawlessly.

 

Bob

 

P.S. - Please note the second unknown device was the acpi-compliant virtual power controller that stated with previous driver attemps the hardware wouldn't start.
