T440P - Not charging

Hi,

 

I've been using my Thinkpad T440p for only few months, When I plug in the charger, battery doesn't charge and doesn't show anything (as if the charger is not plugged in at all).

 

- The charger itself is working.

- If i removed the battery and botted the laptop with cahrger plugged in it works.

- if the laptop is off and i plugged in the charger the battery will charge.

- Whenever I plug in the charger while on battery, the power light blinks but without charging.

 

I've tried to uninstall ACPI Power driver and didn't work, I've tried to update BIOS and it isn't possible as the update require both the battery and charger to be connected which is not possible.

 

Please help

Re: T440P - Not charging

Are you saying it won't run if there is a battery and it is plugged in?  Do you have warranty remaining?

Re: T440P - Not charging

If i'm to start the laptop with charger plugged in and battery installed, It would run only if the battery is charged, and battery would not be charging.

 

(and the only way to charge  the battery is by plugging in the charger while the laptop is turned off). 

 

I've used the laptop only for 5 months, and still haave warrnty.

It's time to use the warranty to get it fixed.

Re: T440P - Not charging

I have a t440p with 2 ssd's, one with manjaro linux and other with windows 10. My main system is manjaro linux. 

Now the battery only charges on windows. Does not charges on linux and does not charges turned off. I works on battery on both systems. 

I already google for a solving and I tryed the reset battery holding power without battery and charger.Can you help me ?

Hi amadlopes!

 

Welcome to the Community Forums. 

 

Please access BIOS and load default settings by pressing Fn + F9 or F9 only then save and exit by Fn + F10 or F10 only.

Re: T440P - Not charging

Could you try to perform a Power Drain on the laptop and check if the battery will charger? Here's how https://support.lenovo.com/us/en/troubleshoot/lpt000352?CID=ww:lenovosocial:20x9m6 - I would like to verify as well, what version of Linux OS is currently installed on your laptop?

Re: T440P - Not charging

Unfortunately I already did that and didn't work. That was the first thing I've done.
For me this is completely nuts. Because if it works on windows it is not broken so why does not charge turned off ?
Thanks.
