Same issue here with a brand new P53, after one reboot it went into airplane mode and would not acknowledge the AC adapter

I have P53 and this is exactly the same. Very unreasonable...

  • Airplane mode on = no charging
  • Airplane mode off = charging

Hi!

 

The solution is simple : Disable airplane power detection in Vantage. I'm not sure exactly how it's called as I am on my phone right now.

 

There is a reason it's on : to prevent tripping airplane breakers.

I had exactly the same issue on my Thinkpad X1 Yoga 3rd Gen. laptop. I had already verified that my laptop was not in airplane mode, nor was there any issue with the middle pin of the USB-C connector as some people suggested to check on this thread. I also had more than one adapters for the laptop which I had tried from different outlets, just to rule out that it was an adapter issue. When I still couldn't figure it out I tried the following:

 

There is an option in the bios under the power management options to disable the built in battery. This is typically used before you open the laptop to replace the battery. I just decided to give it s try. So I rebooted my laptop and pressed F1 a few times immediately upon reboot to take me to the BIOS settings.

 

Then under power management, I went ahead and disabled the inbuilt battery. This will immediately shut down your laptop.

 

Upon doing this, I then rebooted my laptop again. Voila! This time I did not see the error message upon reboot. And what's more, my battery started charging again.

 

So if you have already tried all the other things mentioned above, give this a try as well. It worked for me.

Disabling the inbuilt battery in BIOS settings is what worked for me on my P53:

  • Unplug the power adaptor
  • Disable the inbuilt battery in BIOS settings.
  • Plug back the power adaptor
  • Power on
  • -> No more error message and the battery is charging again!

Thanks!
