There is a DIFFERENCE between 1% driver and battery ICONS.
Battery icons located in dialer package (PHCANOVERBMP.dll)
All you need is :
1)to find and install 1%-compatible taskbar (PHCANOVERBMP.DLL to be exact)
2)Install
Nue driver (its a driver and has nothing to do with icons in taskbar)
3)Now you can enable 1%
To enable-check box "Don't round percentage (1% Increment)"
in start menu>nueTools>nueBattery2Settings
Hope that helps .
