I have a Lenovo laptop on which the ACPI\VPC2004 Driver is missing. I tried looking for the driver everywhere but didn’t find it. Please help!
Let me help you with a step by step guide!
- Install all the drivers except ATK tool and ACPI.
- Download ACPI driver x64 from here.
- Download Lenovo Energy Management tool from here.
- Download ATK Tool from here.
- Install System Interface driver from here
- When you begin the installation, the files will get extracted to C:\Drivers\…. first. Just let the files get extracted there and run the setup from there.
- When the setup asks for a reboot, reboot your laptop.
If these steps don’t solve your issue, try the steps below.
- Go to the device manager select unknown device (Device ID ACPI\VPC2004) and choose to install/update driver manually.
- Go to the folder where Energy utility installed (C:\Program Files(x86)\Lenovo\Energy Management in most cases)
- Select driver in C:\Program Files(x86)\Lenovo\Energy Management
- Reboot your system.
Now your problem should be fixed.

My Lenovo Ideapad 310-15ISK running Windows 7 also had the same issue, but finally, after hours of digging down on the web found the drivers required. Someone uploaded them on Dropbox so get the drivers from there and install them. Once you have installed the drivers, reboot your system. Now the issue should be resolved.

My Lenovo Y580 did not have Bluetooth after I did a clean install of Windows 10. Bluetooth was not visible anywhere in the system. Shortcut fn+f5 did not work.
After the installation of Lenovo Energy Management, I was able to switch on Bluetooth.
