W530 battery control while docked to Mini Dock Plus Series 3

The optimal storage level for my Lithium Ion battery is ~40%. In addition, it is important to allow the battery to discharge fully and then fully charge, in order to prolong life.

 

The Battery tab of Lenovo Power Manager's `Advanced` options, within the `Battery Maintenance...` button, has options for Start and Stop charging percentages.

 

1) Should this be held around 40%-50% to comply with the optimal storage level for my battery?

2) Since I'm on the docking station, I really have no use for the battery. Is simply being plugged into my laptop detrimental, or can this be offset by the options in the `Battery Maintenance...` section?

if you are constantly docked, then keeping the battery around 40% to 60% is the best. This is how battery are usually stored after manufacturing before they are sold to the customer.

Re: W530 battery control while docked to Mini Dock Plus Series 3

Setting "Start charging when below: " and "Stop charging at: " options don't seem to work properly.

 

The battery charge doesn't decrease from the current 100%. However, if using the battery off the dock till it reaches below the "Start charging" or "Stop charging" percentages, the battery will sit at the "Stop charging" percentage indefinitely. Instead, I would expect it to do as told, and stop charging at the "Stop charging" percentage until the battery juice drops to the "Start charging" percentage, at which point it would start charging again until reaching the "Stop charging" percentage again (cycling on forever).

 

Why doesn't this work?

try installing the thinkvantage system update, and update your power manager driver, thinkvantage power manager, and if possible the BIOS firmware.

Re: W530 battery control while docked to Mini Dock Plus Series 3

@lead_org, sorry for the late reply.

 

The only thing that isn't the latest version is my BIOS. I currently have Lenovo G5ET94WW (v2.54) 8/12/2013.

 

Unfortunately, the new BIOS version 2.57 (released March 12, 2014) for my w530 2436 (Win7 x64) DOES NOT make any changes to docking station or battery functionality according to http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/g5uj20us.txt

 

If you still think I should update, I will, but it seems like a longshot. Any other solutions? And more importantly, are other users able to charge/discharge their battery while on the dock and according to the Power Manager settings?

my W530 (all three of them) can discharge and charge to the specific threshold value that i set.

Also, did you install the Power Management Driver for your laptop?
