how to check power adapter serial number
I bought a mac book pro power adapter less an year ago and sometimes it doesnt charge the mac book pro which i have. How do i replace the power adapter, how to find the serial number of the power adapter?.
Serial number is not as important as the information in this article:

... but if you need it for some reason, it is silk screened on the adapter body in microscopic gray ink.
