Hi. I own a TI Nspire CX CAS. I’ve had it for 5 years now and the battery’s been screwy for the past few years. I just ordered a new battery with good reviews from amazon. I’m worried that if I take out the battery my documents and other saved settings will be deleted. Does removing the battery delete anything? I have the modded operating system for my oldschool gameboy games, so I really don’t want to lose my games and settings, as the laptop I used years ago to put the games on there has been broken. I would really appreciate any help. Thank you.
