I have a kindle that lost the ability to connect to the internet or wifi, i think some busted in it but it will turn on and everything in the library that was fully loaded still works. I would think you would be ok. I also found the battery lasts allot longer not trying to ping a connection all the time. Its the original black and white v1... leaves so much to be desired lol
