For nearly two years I was running only Ubuntu on my Lenovo G570 laptop. Recently I changed to dual-boot with arrival of Windows 8.1 Preview. With that I installed some Lenovo provided applications, prominent one being
Energy Management
. After few days of application usage, Energy Management suggested that I use 'Optimized Battery Health', based on my usage pattern, to extend battery life. After making this change the battery never charges beyond 50% (I'm always connected to a power source). My understanding is the application controls charging and maintains constant battery level. Whenever I boot into Ubuntu the same situation (battery never crosses 50%) prevails there. What puzzles me is, there is no Lenovo application on Ubuntu. For that matter I don't use any battery manager on Ubuntu other than the default one.
On Ubuntu the battery status shows as 'charging' but the percentage does not change. On Windows the status is 'Not Charging'.
I'm now concerned about the long term implications of using this option on Windows. How does a Windows based rule apply on Ubuntu? Does Lenovo Energy Management write something to battery firmware (I don't know about firmwares, just a wild guess). What will happen if I remove Windows altogether from my machine?

First a remark that the threadEnergy Management does set to Optimized Battery Healthsays this (03-23-2013) :
The lenovo energy management of windows 8 is having some problems. Could you use the windows 7 version and see if the option works?
Second, as regarding the Battery setting:
Maximum Battery Life
generally means Energy Management will try to squeeze out as many minutes as possible when the laptop is running on the battery.Optimized Battery Health
means Energy Management limits the battery charge to 60% so that the battery life is not prematurely shortened. When a battery is charged to 100% for a prolonged period of time it can actually shorten the life of the battery. That means if the battery can last 5 hours in normal usage when it is new, that battery life will decrease somewhat quickly over time if the battery is always kept at 100% charge. It has to do with the way a lithium battery works. ![Management Management](/uploads/1/2/4/8/124860409/104043817.png)

Third, to have this same effect on Ubuntu, the application must have changed someparameter(s) in the BIOS. Boot into the BIOS to search for them and to change back,or set the Battery back in Energy Management to Maximum Battery Life to charge to 100%.
