2014-08-18, 11:50 AM

Good day to you Sirs.

I just bought a Lenovo G510 running Windows 7 64bit and I am missing the ACPI\VPC2004 driver and root\LenovoVhid driver. Well i actually have first one on cd, but it keeps failing to install correctly.

 

I checked files here

and here

Hope you can help me with this.

hi Mikasa,

 

Welcome to the Lenovo Forums.

 

Can you try this driver:

 

Lenovo Energy Management

version 7.0.3.4
21.4MB

 

 

Let me know how it goes.

 

Regards

hi Mikasa,

 

AFAIK, the Lenovo VHID Device / User Mode Driver Framework (UMDF) minidriver is usually used by the Lenovo Energy Management to control power management schemes.

 

From this article, the Pass-through HID to UMDF Driver service exists in Windows 8 only and the MsHidUmdf.sys driver is included with Windows 8 and later versions of Windows. Since you have Windows 7, I would not worry about this Unknown Device.

 

Here's what it looks like in Windows 8:
