The TI 84 Plus graphing calculator takes 4 AAA batteries as well as a back up button cell battery to ensure that just because the batteries die does not mean the learning or storing has to.
The t1-84+ has the addition of a usb cable and preloaded apps.
The TI 84 Plus Silver Edition has a replaceable cover which you can have a different color on. And it also has a larger capacity for memory.
Perhaps you have to change the battery. It is also possible that the calculator is damaged.
press the "2nd" button, and then press "On"
This is like asking how people work. You should be more specific if you want a good answer.

It is an improvement upon previous models of calculators, and the Silver Edition is just a fancy way of saying it is better. The TI 84 plus Silver Edition is a graphing calculator with a relatively large memory capacity and relatively fast processor.
The two models have very different user interfaces. For most purposes, a TI-84 is easier to use and much more popular than the TI-86, and this may have been the reason the TI-86 was discontinued.
If it has rechargable batteries, open the back, take out the batteries and put them in a charger. When recharged, put back in the calculator. If it doesn't have rechargable batteries, just buy more batteries.
To scroll, use the up and down arrows. If you want to scroll faster, press 2ND ALPHA and then use the up and down arrows.
Everything about the TI-84 Plus Graphing Calculator is special. It has 9 times the memory of ite predecessor meaning it can hold up to 94 apps and still be used to complete complicated math problems with just the touch of a button. It can be customized with faceplates and slide cases so your student can study in style, and just in case something does happen to this gem, it comes with a 1 year manufacturers warranty guaranteeing your wallet will stay intact since you wont have to buy any more. These are just a few things special about this calculator.

a part of speech
First, it could be flat out broken, in which case you will need a new one. Check if this is the case by first making sure there are new batteries in the calculator. Second, make sure your screen is not just really bright. To do this, push the on button and then repeatedly push the 2nd and then up arrow to make the screen darker. If this doesn't work after a short time, its not the problem. You could finally try to turn on your calculator by resetting it. This involves taking out the batteries for a few minutes. If that doesn't work, your calculator appears busted and you probably need a new one.
The easiest way to learn how to use a new calculator is by trial and error. This calculator is very powerful if you know how to use it, but it can be confusing at times. (though much less so than the more powerful TI calculators. I digress) If you do not have time for trial and error though, you could find a user manual online at: http://www.education.ti.com/guidebooks/graphing/84p/TI84PlusGuidebook_Part2_EN.pdf And a helpful hint in general, if you are looking for a specific function that you can't find using menus, try looking in the catalog.
