I have taken apart and it looks dry but still wont turn on
The only thing that I can recommend it to stick it in a zip-lock bag full of dry rice for 24hrs. Sometimes there is moisture that you just can't see & rice has a way of attracting liquids from electronic components. Hence, potentially saving your electronic device. If this does work -- if I were you I would suggest always storing your calculator, ritually, in a zip-lock bag so this does not occur again (I do this -- TI-84s are not cheap accessories -- better safe then sorry). Good luck!

I had the same problem but its best to first just dry it out and with a hair drier at low. Forget about openning it up i couldn't get mine open either. Let it sit for a day and then take the batteries out and press the on button for 30 sec. then take new batteries and put them in and it should work.

Thats because the OS is corrupt. Follow the manual and reload the OS, try the 2.43 OS

E is the calculators form of scientific notation. so 2.145274703E14
is really 2.145274703 x 10^14 or 214527470300000

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

Press the 2nd key (yellow one) and then press the UP arrow to increase brightness or down to decrease but seems like you to need to press UP arrow.
