the Apple TV won't accept my password, but it is fine on my laptop. Why?
brand new login and password, which works fine on my laptop, but won't be accepted by my Apple TV. Anyone??

A notebook may want startup/wake login credentials that are likely different from your Apple ID, but Apple TV wants your Apple ID account and password to log in.
What is the exact error message when it won’t accept your password?
Is this during setup, or are you logging in to a specific service?
