My first guess was cracked wire (to signal pin) in ac adapter.  Can you try a different adapter?

No but there are extremely little chances it comes from a cracked pin or defect cable

Everything works fine without battery attached

With battery the laptop doesn’t want to charge and it uses only the battery power

I can use the machine without battery but if I knew I would have bought a desktop workstation

I finally found the solution it works perfectly now :

 

  1. Shut down your laptop.
  2. Unplug your charger (power cable).
  3. Remove the battery from your laptop.
  4. Press and hold the power button for 30 seconds, then release it.
  5. Put your battery back in and plug your charger into your laptop.
  6. Turn on your computer, and it should start charging now.

2 person found this solution to be helpful.

This helped me too

Re:Incorrect AC adapter is attached: UNSOLVABLE

I bought  a Lenovo  ThinkPad P53 Home and Business Laptop (Intel i7-9750H 6-Core, 128GB RAM, 1TB m.2 SATA SSD, 15.6" 4K UHD (3840x2160), NVIDIA Quadro T2000, Fingerprint
cost me 6k.  I run massive Cad files and excel spreadsheets on multiple monitors with it!  


After 2 weeks I got the message “the ac adapter is not powerful enough”...yada yada

 

I’ll confirm that it is in fact the 170w original adapter.  I even tried An after market adapter Without success.

 

i bought from New Dream Ink through deal king.  New dream has been helpful in sending me shipping and customs docs which made it easy to ship back to them. They have since shipped me a new one, but again, after 2 weeks of use, same message.

  
As others have stated, charges while off not while on.  

New dream ink have again sent the shipping and customs docs as I am now returning for a full refund.  deal king even contacted their Lenovo rep...no help there!   
 

I use this computer to run my business, I have 3 young kids and am building a house, so I’m really busy and this has been a major inconvenience  in my life!   I was excited for this laptop after the hinges completely gave out on my DSI lap top after only 2 years.   Dont even get me started on that..(3k DSI laptop and hinges give out)

This is without a doubt in my mind, a Lenovo issue, and with a quick search on line it’s not an uncommon issue! I’m surprised they are not more active in resolving it!!

My battery is not removable without opening the machine. And I don’t want to risk voiding the warrenty on a 6k machine. After receiving a replacement laptop under warrenty and again having the same issue within the same 2 week time period, I am returning for a full refund.

So this is a Lenovo community forum and often times a rep will contribute to a forum related to their products to reassure customers that they are working to resolve a particular issue.   I’ve seen  this particular topic come up multiple times in multiple forums, but nothing from any Lenovo reps that I have seen.  This is a pretty serious issue to be so common!   
LENOVO...are you addressing this?
