Thinkpad T480s not recognizing the battery properly, battery threshold disappeared

2020-05-28, 1:00 AM

Hello everybody,

 

 

Lenovo Vantage is not properly recognizing my battery anymore. I use the battery threshold option quite frequently, but today when I tried to use it, the option was just not there anymore. Then I noticed this message on the right hand side:

However, the battery still charges normally, but only up to the limit I previously set, which was 80%.  Also, the battery details are completely missing, it is like the software just reads empty strings:

Basically, I am stuck with only being able to charge the battery to 80%, since the option is missing. Things I have tried:

 

  • flashing old bios
  • using lenovo vantage enterprise (even with a bios version from its time)
  • pretty much every suggestion in every post that I could find online to similar issues

 

 

Thank you for your suggestions!

Solved! See the solution

it did not work, unfortunately. I will install windows on another drive when I have time and see if the problem persists. If so, then the battery is probably dying.

Alright, I finally got it to work by reinstalling Lenovo Settings Power Manager from https://support.lenovo.com/us/en/downloads/ds541411
