Hi freewind,

 

Welcome to Lenovo Community! And happy to have you here.

  

You can Lenovo Settings which has a centralized access to all major hardware features and controls on any Lenovo Windows 10 machine. It has an option to set Battery Charge Threshold which can be set around percentage of 45%-100%

  

I hope the above information helped you. 

Please feel free to post in Lenovo Community Forums if you have any further queries!


Regards,
Prabhansh

Re: How to change battery lower threshold on T570

Maybe I wasn’t clear last post. Laptop have Power bridge technology. And I would like to computer change from external battery to internal battery when external battery has 10% juice left.
By default, external battery will drain to 5% and then change to internal battery. Maybe Lenovo have software application for Power Bridge technology.
Battery Charge Threshold option is not the thing I need.

Thanks for explaining it, but I'm afraid Smiley Sad that there is no manual customization option in Power Bridge technology.

Re: How to change battery lower threshold on T570

It is possible to change this in register or maybe in CMD?

It's hard to say from here as I don't have any particular system with Lenovo Power Bridge installed in it to modify registry settings may be someone will chime in with their own experience.

Re: How to change battery lower threshold on T570

It is controlled by EC firmware (a component of BIOS).  It is not customizable by user.

Re: How to change battery lower threshold on T570

It is real sad that Lenovo Power Bridge system doesn’t have such option. My External battery will have real short lifetime because is each time drained to 5%. More you can see here

But you probably know this 
It's sad that Lenovo ThinkPad does not have this option. Newer expected this form "premium" business laptop. It looks like the company would like to sell more batteries.

Re: How to change battery lower threshold on T570

Hi, do you find a solution for this issue?

I bought the same laptop and I also think it's not normal that the batteries switch to 5% while everyone knows that lithium batteries should not go below 10%

And we're back...

Move delayed but still coming
