Disable the built in battery / ac adapter attached at home

Hi guys,

I was wondering if there is any manipulation to disable the built in battery for the lenovo x1 yoga 2 gen when working at home with ac adapter atached to increase the battery life.

Thanks

Re: Disable the built in battery / ac adapter attached at home

Hi

It's impossible to disable the battery programmatically and keep the laptop working. Once the battery is disabled in the BIOS Setup, laptop will power off automatically.

To save the battery life do not charge it fully. To do this use Lenovo Settings application and Custom Battery Threshold feature. Set start charging level to, for example, 40%, and 50% as a stop level.

Note, Lenovo Power Management and System Interface Foundation drivers should be installed either.

Thanks for the reply,

So as you mentionned if i set the stop level at 50% and the start level at 40% this means that battery will stop charging and the ac adapter will keep powering the yoga without charging the battery, or the battery will stop charging at 50% and once the level gets to 40% the ac adapter will recharge the battery until 50% ??

The answers for both questions - yes.
