uT440s Battery not charging to full capacity- 3-cell & 6-cell

I have two external battery packs, the 3 and the 6 cell batteries. Neither of them will charge at full capacity. The laptop is brand new, as well as the two batteries. 

 

The 6 cell battery is shown as charging, but it is stopped at 59%, and Power Manager shows 5:00 hours to fully charge (it shows this constantly, with no change whatsoever). 

 

Similar problem with the 3-cell battery, stopped at ~75%. 

 

I have deleted the battery driver from Win7 Control Panel. I have changed Charge Mode from alway fully charged to battery health and back to full charge, I have also tried 80% charge threshold. 

 

Running Windows 7 (downgrade form Win8)

 

Any advice?

Hi Radu_umbres,

 

Welcome to Lenovo Community!

 

As per the query we understood that you are issue with the Battery not charging completely on your ThinkPad T440s.

 

To resolve this issue please restart the system connecting ‘Power Adapter’. Wait till the system boot completely and then go to ‘Device Manager’ then uninstall ‘Microsoft ACPI-Compliant Control Method Battery’ under battery option. After uninstalling shutdown the system, remove ‘Power Adapter’ and reconnect, then switch ON the system and check if the issue still persists.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Thanks Hemanth!

 

I have tried this using both external batteries - it does not work. 3-cell battery is stuck at 80%, 6 cell battery at 56%.

Hi Radu_umbres,

 

Thank you for the reply!

 

I am not sure whether this will help you or not, can you check with uninstalling Lenovo power manager application from the system.

 

Best regards,

Hemanth Kumar

I have uninstalled Lenovo PM - no change, uninstalled the battery again from Control Panel - no change. I now have reinstalled Lenovo PM - no change. 

 

Should I seek support?

Hi Radu_umbres,

 

I'm really sorry to hear that the suggestions made here have been unsuccessful. But I just want to confirm whether it is an issue with hardware or with the software, to confirm on that you can check with one last option on booting the system with Linux bootable disc.

 

If the issue still persists then it could be with hardware and you can contact Lenovo support center for further assistance.

 

Please click here to visit the link where you can get the list of support contact numbers, select the respective region and give a call.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

I have booted my system using the Lenovo Linux USB bootable. I left the system on for several hours, then checked it under Windows - no change. 6 cell battery will not charge above 56%.

Hi Radu_umbres,

 

Did you checked with different power adapter?

What is the wattage specified in the AC adapter (E.g.:- 45Watt or 65Watt)?

 

Hope to hear back soon!

 

Best regards,

Hemanth Kumar
