SOURCE: 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 amazon.com and spare your TI84PLus SE.

Put in new batteries and try again.
If new batteries did not solve the problem, the next thing to check would be the battery terminal.
If the battery terminal is rusty, the battery power won't contact and the calculator won't turn on. So, use a flat small screw drive to scratch the battery terminal so that there would be contact.
If the above is not the problem, the next to check would be the wire connecting the battery terminal to the the calculator's main board. There is a wire between the battery terminal and the calculator board. When the battery is inserted, the power from the battery goes from the terminal to the board through this wire. There is a possibility that this wire is cut in-between or is loosing contact. In this case, you need to get a small screw driver and carefully disassemble the calculator in order to check the wire.
If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.
If non of the above helps, then it means the calculator is dead and needs a replacement.
