Thanks Brad! Yes, it's always been connected to AC power because it doesn't operate on batteries. I just assumed because the manual said the lithium battery only lasted 5 years that it was way past due for replacement. I'll have to check out the memory function next time I'm at my daughter's home where the keyboard is located. Appreciate your help!

Hello. I want to replace the lithium battery in my casio privia px-310, but I don't know where the battery is located in the instrument. Also, how difficult is it to replace the battery once I find it. I've had the keyboard for at least 15 years, so I'm sure the battery is dead! Thanks!
