Battery won't charge past 60%

X1 Carbon, gen 1.

Windows 7 and Debian.

Battery won't change past 60%. In windows, it shows the battery as 100%. The Battery Manager software says that the battery is in poor condition, and can only store 60% of its original full charge capacity. If I charge it to 100% in windows, and boot Linux, it shows that the battery is actually charged to 60%. It charges up to 60.15%, then discharges to 60%. acpi -i shows that the battery is only being charged to 60% of its full capacity, as well. However, it Windows, shows this charge as 100%. It only runs for about 2 hours (being 1.5 months old). In the beginning, it could run for 4-5 hours. I suspect that a software/firmware update has put a limit on the battery charge level.

 

Is there anything I can do to get the battery back at full capacity? 2 hours simply isn't enough for an ultrabook...

Hi Martinvdk,

 

Welcome to Lenovo Community!

 

I am sorry to hear that you are facing the issue with battery not charging completely on your ThinkPad X1 Carbon.

 

Please check with uninstalling Lenovo power manager application from your system and if you find that the issue has been resolved then reinstall the application.

 

Please let us know the findings after performing the troubleshooting steps.

 

Hope to hear back soon!

 

Best regards

Re: Battery won't charge past 60%

Hi hemanth_lenovo

 

I tried to uninstall power manager, but the battery still won't change past 1666 mAh:

$ acpi -i
Battery 0: Full, 100% Battery 0: design capacity 2776 mAh, last full capacity 1666 mAh = 60%

This corresponds to what Power Manager reports as "poor" condition:

Your battery can store 60% of its original full charge capacity. Click the Help button to learn about increasing battery lifespan.

I got the laptop on july 16th, a bit more than a month ago. It seems like the battery degraded momentarily. After easily running up to 5 hours on a full charge for some weeks, it suddenly only ran for max 3 hours. How is it possible?

 

Martin

-edit-

Correction. I got the laptop on june 25th. I know, I know, summer holidays, lost sense of time, etc. Smiley Tongue

martinvdk,

is your laptop new? What are the "Manufacture date"', "First used date", "Cycle count" values? Look at them in Lenovo Power Manager, Advanced mode, Battery tab.

Re: Battery won't charge past 60%

I hope the battery wasn't stored on the heat before laptop was produced.
The count value 49 isn't so big but according to the short time of laptop usage it means very intensive charge/discharge mode.
So I'd suggest to perform the battery reset using PM capability ("Battery maintenance" button).

Re: Battery won't charge past 60%

reading this string realizing it is a couple months old, but the answer is different than notes above. you simply need to turn off the conservation mode in settings. Lenovo has a feature to save the life of the battery by only charging to 60% if you regularly keep the laptop plugged in. To fully charge, simply open the j"energy manager" program found in the windows list of applications on the main screen, click around until your find the settingfor conservation mode and click to turn it off for the PC to run at full performance versus battery conservation mode. It will immediately start charging to reach full capacity. You don't need any new software, drivers or anything.

Re: Battery won't charge past 60%

Hi - having the same problem. I recently upgraded my X1 form Win7 to Win8. I don't see application for power manager. Did I accidentally lose this application?

 

If so, any idea how to fix ? My battery won't charge past 49% because its stuck in conservation mode.

 

Thanks.

Hi Jk967,

 

Welcome to Lenovo Community Forums!

 

Please see this KB article on making a change to this setting.   If you don't have the power option listed in settings, you can download Lenovo Setting Dependency Package and check the settings provided in the KB article.

 

Hope this helps.

 

Best regards,

Hemanth Kumar
