“Missing ASUS ACPI Driver windows 10

There is a step by step guide on what to do here
http://www.tomshardware.co.uk/faq/id-1959382/missing-asus-acpi-driver-windows-back.html It refers to Windows 8, but the remedy has worked for many other people.

If you don't feel like trying that yourself, then all that I can suggest is that you ask you local computer store to help, or find a friend who understands windows computers, show them this thread and ask them to help you with the process of installing the

How to really uninstall a Lenovo ACPI-compliant Driver

Hi everyone,

I have a Lenovo Y40, and ever since I upgraded to Win10, my PC cannot read the battery gauge correctly. After doing some research, I realized Lenovo Energy Manager and the Lenovo acpi-compliant virtual power controller driver are the problems. (I hate junkware)

I deleted Lenovo Energy Manager with no problem, but I can't get rid of the Lenovo acpi-compliant virtual power controller driver. Here are the steps I'm stuck with:

- If I go into device manager and uninstall the driver, the driver will disappear, and upon restart, it will show up again as an unknown driver.

- If I uninstall/disable this unknown driver, upon restart/hibernation, it will come back again under 'system devices' as 'Lenovo acpi-compliant virtual power controller driver', as if I didn't do anything.

When this driver is listed as unknown driver or temporarily disabled, my battery gauge issues are immediately resolved. Does anyone have any idea how to get rid of annoying drivers like this one once and for all?

Thank you!
