    To be more clear on my previous message. I've replaced the batteries and it still will not turn on, just a blank screen.

If it won't turn on most of the time what I do is take the back cover off the calculator. 6 t-6 torx screws and 1 phillips screw for the back-up battery. then pop the cover apart and on the back part where you put the batteries you should see 2 little metal probes sticking out that make contact with the pads on the calculator board. bend these to a 45 degree angle and it will make better contact with the pads. what causes this is that the metal will very so slightly expand and contract with the temp changes and cause the metal probes to lose their contact with the board, in turn killing all power to the board. give it a shot. it will most likely work

Ti 84 plus can't transfer 8C010000

Transferring data and programs to the calculator requires a lot of energy that almost dead batteries cannot provide. Change batteries and try the transfer again using TI Connect. To transfer from a similar calculator the receiving one must be in RCV (receive mode).

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

Ti-84 Plus help!!

It seems like you're just starting off. And....

....The best thing you can do is begin hacking away at different buttons until you figure out what certain things do. I guarantee, that you will discover some pretty amazing things within the TI-84.

Compared to other calculators, the TI-84 is pretty user-friendly. Don't be scared.

In my opinion, Texas Instruments' customer service is one of the best in the nation. Call them for specific questions, they're great at the basics but not-so hot at the advanced. Friendly & helpful people, though.

Change TI 84 OS to TI 89 OS??

And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or and spare your TI84PLus SE.

Why do some TI83 program work on a TI84 plus and other don't?

Ti 83 and ti84 really have no difference and operate the same. There was something different or you had varibles used by multiple programs that conflicted w/ the ti84 and it would have done the same on the ti83. If you like to rework it and need help email me at
