Y 50-70 power adaptor not supported


I'm having problems to charge my laptop, since its only charging while off. When i turn it on it keeps saying that the power adaptor is not supported. I already tried to use a power adaptor of an identical computer and it keeps showing the same message. I searched in the forum for answer and tryied all the fixes I could find, but still not  solved.

Please somebody help me!

Hi there, Pardoso –


Thank you for writing in to the Lenovo Forum - happy to have you here today.


Just to check, do you have these below part numbers on the AC adapter label?



If you have a different P/N # then it's likely the cause of the "Adapter is not supported" and you may need to contact Lenovo on how to go about getting a replacement AC adapter.
