I had the same problem, and i've already solved it. Go to Lenovo Settings App, go to Power (battery icon), then you will find AIRPLANE POWER MODE. Disable it, and also the auto detection of it, and the charger issue is fixed :)

Thanks very much - solved my problem. When my T470p is in flight mode and AC adapter connected I got the same problem. Switched off Airplane flight mode and the problem went away. The machine went into flight mode after installing Lenovo system update and hot key integration.

In my case, I have 90w charger, and with the AIRPLANE POWER MODE disabled I'm getting this error, but after I enabled it, it's working perfectly well now.
Computers are too smart these days.

Thanks for the answer.  This I was able to resolve my issue by taking laptop out of airplane power setting.

I have Lenovo ThinkPad T470p and it is not charged with ThinkPad 65W Slim AC Adapter

 

i see "Incorrect AC adapter is attached. This AC adapter cannot provide enough power for normal operation of your computer. You may be able to charge your battery with this AC adapter if your computer is in sleep or shut-down states."

 

Switching Airplane Power Mode to OFF does not help. But it can be charged in sleep state.

 

What else can I do to charge my T470p with ThinkPad 65W Slim AC Adapter when I'm working on it?

You need a 90W or greater adapter for that.

I don't work for Lenovo. I'm a crazy volunteer!

Re: Incorrect AC adapter is attached

I have a custom built W-540 and this "Inccorrect AC adapter is attached" message would start happening.  I am running Window 7 pro.  I have corrected the "airplane mode" settings.  I have tried a new battery, I have rolled back the power management and to no avail.

 

I does charge when I close the lid.

 

Why can't lenovo figure out what is causing this problem?  Or is it something to do with the actual connector that break down after a while?

Could you provide the laptop specification and the AC charger' sticker photo with detailed information about its features?
