Ideapad 300-17ISK - Windows 7 x64 (ACPI Driver)

Hi All,

 

I've tried to downgrade my laptop to Windows 7 x64 but have found that there aren't specific Windows 7 drivers for this laptop on the Lenovo Website Smiley Sad However, everything works well as most of the drivers are Windows 7 & 10 compatible ... except 1 key one the ACPI driver that is Windows 10 only ... unfortunately this means I can't adjust any power options including the screen brightness ... so i was wondering has nayone else had any luck in installing Windows 7 on one of these or similar laptops ... or can someone point me to a compatible ACPI driver?

 

Thanks,

 

Luke

I think the "Lenovo PM Device" might be available through windows update, but I'm not sure if it only works on Thinkpads.

 

I have not gone through installing Windows 7 x64 on my Ideapad 300 yet, but I plan to and have considered drivers from the G70 Z710 & Z70, I think there are similarities, but they are different chipsets so Windows Update is probably a better option for ACPI

 

If Windows Update doesn't list under "Optional" it can also be downloaded from the Microsoft Update Catalog

This link probably will only work in Internet Explorer (it requires an ActiveX control).

 

An option is to use the "Windows Mobility Center" to control screen brightness >>Programs>>Accessories>>Windows Mobility Center
