Lenovo Energy Management preloaded software effecting Linux OS

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.

Re: Lenovo Energy Management preloaded software effecting Linux OS

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.
