I have a 1st or 2nd generation iPad and it’s been charging in the wall for more than 24 hours but all I get is the Apple logo. My power button seems stuck as well, It doesn’t move when you press it. I have tried to plug it into my computer to do the reset but it doesn’t appear on my iTunes so I wasn’t able to go that route. Is there anything else I can try?
Not sure if this will help but sometime device may get into a weird state. Have you try a hard reset? i.e., holding down power and home button for 10 seconds -- the screen should go blank and then show the Apple logo, that's where you can release the button.
It sounds like the device is quite old, possibly that the battery in the device has failed.
You should first check you are using a 10W iPad charger, but if that still doesn't work after an hour or two of charging it is time to look for a replacement battery.
You should first check your service options with Apple: https://checkcoverage.apple.com/
However given the age of the device even if they would service it (which is unlikely) then the cost would be prohibitively expensive.
In this case you could look at a DIY battery replacement there are instructions on sites like iFixIt, or through a local phone repair shop.
