Samsung Battery Life Extender?

**KayeNg** · December 31st, 2012

Hi guys! In Windows 7, I can run Samsung BatteryLifeExtender.exe

It has the option to set the charging limit to 80% if the laptop is always using AC, and you can set it back to 100% if you're planning to use it outdoors.

I don't think I can run this in Lubuntu. Any way around this? Or should I just boot into Windows partition and access the battery life extender from there?

Thanks guys!!!

It is unlikely that you can run BatteryLifeExtender on Ubuntu, since it is a Windows application. I am more familiar with IBM/Lenovo laptops, which have the same feature. There is a kernel module available (tp_smapi) for these laptops, which makes the feature accessible to the operating system and which allows to set start and stop battery charge thresholds.
However, I haven't found something similiar for Samsung laptops.

TLP does that for Lenovo/IBM laptops, if Samsung uses same method, that should do the trick as well.

The battery control feature are implemented by tp_smapi and are independent from TLP:

Does that mean I should do the tp_smapi thing before the TLP?

Sorry guys I'm really new to this.

AFAIK this option should be in BIOS. I have Samsung NP-RF511 and I can set charging limit to 80% in BIOS.

Hi,

tp-smapi won't work with your Samsung. You may take a look into your BIOS setup for an option to set battery charge thresholds.

TLP will help you to save battery power though.
