very short battery live in my yoga 11e chromebook

I think im affected by this battery problem

 

https://support.lenovo.com/us/en/documents/ht102953

 

the image installs succesfully but i cant see any message in the syslog saying anything about the battery update, because is empty all the time. top tool shows an uptime of 30 minutes... long enough for the upgrade to finish. I tried it several times. how can i tell what version of the battery firmware am i running?

 

im still getting very low battery live (around 2h)

 

thanks!!

ablackoka,

 

The symptoms seem to match .   The support tip you reference is being updated in the next 24-48 hours.

You might try this alternate / new solution....

 

SYMPTOM

 

In ThinkPad 11e Chromebook and ThinkPad Yoga 11e Chromebook, the battery may experience poor longevity or not be able to power the system with the battery alone.

 

 

SOLUTION:

 

To update the battery firmware:

  1. Logon to the Chromebook and update the Chromebook to the latest version of Chrome OS.

    (https://support.google.com/chromebook/answer/177889?hl=en)

  2. Press Ctrl-Alt-T to enter the crosh terminal page.

  3. Plug in the A/C power adapter and keep it plugged while performing the following step.

  4. In the crosh terminal page, type battery_firmware update and press Enter to update the firmware.  It may take up to 10 minutes.  Do not remove A/C power until the update has completed.
