1802 Unauthorized network card after an SSD change

I just got a brand new T460. I wanted to replace the SSD with a bigger one, so I opened the laptop and replaced the disk. I haven't touched any other components, everything is original. Now when I start the laptop it gives this error:

 

1802: Unauthorized network card is plugged in - Power off and remove the network card. System is halted.

 

However I haven't touched any of the network cards. I returned the original SSD and the same error appears, so now I cannot even start the laptop.

 

Any ideas how to fix the problem?

Hello, Uraster

Did you remove the AC charger cable and external battery, as well disable internal battery in the BIOS Setup before SSD replacement?

Try to remove the wwan card from the slot to test the laptop and BIOS ability (do not forget about AC cable and batteries). Then insert the card and test the laptop again. Unfortunately, I assume you'll see the same 1802 error. Note the symbols/digits at the the end of the error string (2 x 4 with slash) and post them in your answer.

Strange... I removed the battery and the power supply (which I tried before as well), then left the laptop like that for 3-4 hours. When I turned it on, it worked fine (with the new SSD I installed).
