Lenovo x240 battery observations and inquiries [plugged in not charging]

Hi, Have a few observations and questions regarding the battery of x240. 1.Haven't really noticed before, but when we plug in the charger, should the charging info for both internal and external battery read "plugged in, charging"? 2. I've noticed that mine only has 1 (either internal or external) that reads "plugged in, charging" while the other isn't (plugged in, not charging) - I initially thought that once one is done charging, the other would activate and charge but it's apparently it doesn't. 3. Haven't really found out the issue, i.e. hardware or software. Sometimes it's the internal battery that charges, sometimes it's the other - do I have both defective batteries? Is it a software issue? Below are the things I've tested/tried 1. I've uninstalled the devices drivers in the device manager, restarted - still the same. 2. Install / re-installed the lenovo power manager driver - nada. 3. Tried charging the laptop while it is powered down - and both got fully charged!? Is anyone experiencing the same issue? appreciate the advise / help and thanks in advance.

Re: Lenovo x240 battery observations and inquiries [plugged in not charging]

Hi Legapau,

 

Welcome to Lenovo Community!

As per the query we understood that you are facing issue with 2nd battery not charging on your ThinkPad X240.

Shutdown the system and remove AC power adapter & battery.

 

  • Connect only AC power adapter and switch ON the system.
  • Go ‘Device Manager’ uninstall ACPI adapter from that.
  • Shutdown the system and connect the Battery and AC adapter and switch ON the system.
  • If the issue still persists then run ThinkVantage system update utility so that it will update all the required drivers and application.

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: Lenovo x240 battery observations and inquiries [plugged in not charging]

Hi Hermarth,

 

Appreciate the reply, mate.

 

To clarify, I am not having issues with just the 2nd battery, more like the batteries in general - sometimes it's the internal that doesn't charge, sometimes it's the external, sometimes both. But I've noticed the battery charges when the laptop is shutdown.

 

Before the exercise battery was 85% internal 27% external, after completing what you suggested below are my results.

 

1. Noticed the external battery is plugged in and charging, while internal remains plugged in and not charging - same issue as before.

1a. Will observe if internal battery charges once external is 100% however if it does, is this the normal behaviour?

 

Please note that I have also updated my BIOS tothe latest version from the thinkvantage software update.

Hi Legapau,

 

Thank you for the reply!

 

Please unplug and re-plugin the AC for few times to reactive the charging procedure.  Check charge mode in Power Manager; ensure that "Always Fully Charge" is selected.  

 

Swap battery from the same model and check if the issue persists or not.

 

Hope this helps!

 

Best regards,

Hemanth Kumar

Re: Lenovo x240 battery observations and inquiries [plugged in not charging]

Hi,

 

Thanks for the response and apologies for the late reply.

Took some time to observe the laptop but I guess I found my answer.

Looks like the laptop doesn't simulataneously charge the internal and external battery. Noticed that it charges the external first, then the internal. Looks like this is how it really works. Lucky for me for not sending my laptop in for warranty or buying a replacement battery.

 

Thanks again and happy to be part of the Lenovo community.

 

Cheers and happy New Year!

Re: Lenovo x240 battery observations and inquiries [plugged in not charging]

I have had this issue on several Lenovo's. What makes the x240 different is the internal battery. What resolved my issue for every instance was the following...

 

1. power down machine

2. take off battery on the back

3. unscrew the 8 screws & remove case to see internal battery

4. unplug internal battery

5. press & power button 30times (to clear any power on the board)

6. plug internal battery back in

7. put case back on secureing all 8 screws

8. put external battery back on.

9. plug in & power up
