Looks like the driver has been updated again - the download page displays the date 24/7/2016. Unfortunately, I still can't see a difference - it doesn't seem to work correctly, or at all. When I click on it, nothing happens... and the date on the file still goes back to August 2015...

For lenovo machine, except for Think system, some drivers may not be in Companion or system update.
But you could check windows update in device manager.
If there is no newer version, then the installed driver is the latest version.

I have the same problem. i downloaded the driver today. it was updated couple days ago.
but once i want to install it, it just won't.
can't install (upgrade).
and in device manager it says that it's up to date, although its date is old (2015).

When installing with the log enabled, the following log information is recorded:

Can a Lenovo employee comment on this how this could be fixed?

Good news! (Kind of)
This was from a thread here: https://forums.lenovo.com/t5/Lenovo-IdeaPad-100-305-500-Edge/Energy-Management-Driver-won-t-install-...
"I had the same problem. I found a utility that let me extract the contents of the installer. After I did that, I went to Device Manager. located Lenovo ACPI-Compliant Virtual Power Controller in Device Manager, right-clicked it, and updated the driver with the drivers I extracted with innoextract."
Utility download link: http://constexpr.org/innoextract/
EDIT: Checked the contents with Innoextract - they're indeed 2015 versions and exactly the same as what's installed. No point in installing them.
