Yes. You can make programs directly on the calculator by pressing the PRGM button and selecting NEW. Or, you can download TI-Connect free at the ti site and use that program to make programs. Making programs on the computer is faster and allows you to save the programs as normal computer files. Then you use a cable to send the programs to you calculator. You can also send programs from your calculator to your computer. I would recommend programming on ti-connect and sending the files to your calculator, just make sure you don't exceed the memory, which shouldn't be that much of a problem on the silver edition.
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 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"
The t1-84+ has the addition of a usb cable and preloaded apps.
This is like asking how people work. You should be more specific if you want a good answer.

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.
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.
