Re: Lenovo y520 completely freezing randomly only when AC adapter plugged in

I think I have done all the steps but it stays as Unknown Device until I connect to the internet. After I turn the internet on, it immediately gets installed.

Steps I've done:
1-Installed gpedit
2-Uninstalled the acpi driver checking the "delete the software box"
3-Manually deleted "ACPIVPC.sys" from "C:\Windows\System32\drivers"
4-Opened gpedit
5-Enabled "Prevent windows from sending an error report when a device..." and "Prevent device metadata retrival from the Internet".
6-Enabled "prevent installation of devices that match any of these device IDs" and clicked "show"
7-Entered these to the boxes:
ACPI\VEN_VPC&DEV_2004
ACPI\VPC2004
*VPC2004
8-Restarted the laptop

From there, the device stays as unknown device until I connect to the Internet.

Re: Lenovo y520 completely freezing randomly only when AC adapter plugged in

Hello, I managed to delete the driver without it automatically re-installing itself. But still the freezing problem occurs. Will be trying to find another solution.
