Lenovo Energy Management preloaded software effecting Linux OS

[steveplatz]

I have a new Lenovo U260 that shipped with Windows 7. I now have an Ubuntu variant installed on the machine as a single-boot OS. I have noticed recently that my battery will only charge to 80% and then stop charging and I am wondering if the preinstalled Lenovo Energy Management software can still be effecting the battery charge state. There are not any options to manipulate the power management in BIOS.

The Lenovo software must be able to affect the charging
on a hardware or bios level. I had no idea.

If so, short of re-installing Windows and changing it back,
I don't know what you would do.

Some input from Lenovo techs would be helpful.

Yes, I would like to have some more input from Lenovo techs, hopefully there is another option than re-installing Windows. Here's another interesting fact, the battery is reporting a full charge while I'm running a live session on the same machine with an older Linux kernel 2.6.32-33-generic. However, as I reported here, when I look at the acpi battery info and state, I am still seeing the same numbers as I was seeing while using the updated Linux kernel.
