How to turn on newly bought TI-84 Plus Calculator?

My aunt recently bought me a new TI-84 Plus for college and after opening the package and inserting all of the batteries I can't seem to figure out how to turn the calculator on. I've tried simply pressing and holding the ON button & taking the batteries out and putting them back in. I've also hooked it up to the USB cable that came with it, but after 15 minutes of charging nothing seemed to happen. Am I doing something wrong or forgetting something? Do I just need to let it charge more or is there some software I need to download or something? Thanks to everyone in advance.

Wow, I'm late.

Try plugging the calculator into your laptop. This should make it turn on if the [on] key doesn't work.

You could also try turning it on, then press [2nd] then hold down the up arrow until you see a cursor flashing. If it's been 10 seconds and you don't see anything that's not good.

Try removing the backup battery (and replacing it) and one of the AAA batteries. Then wait 10 minutes, then replace the backup battery and AAA battery. This should force the calculator to turn on.

If nothing worked, then it sounds like you have a defective calculator. :\
