Wondering how to remove the cover on your Kindle 3?
Set the Kindle on a table or other stable surface and kick off the cover.
Note the metal nub sticking out about two-thirds of the way from the top of the Kindle.

This is the locking mechanism that prevents you from popping out the Kindle.
Push the metal nub (or latch) down in the direction of the bottom of the Kindle.
It should slide down by a fraction of an inch.
This releases the latching mechanism.
Push the top of the Kindle horizontally, away from the metal nub.
The Kindle 3 has become difficult to find as newer models are introduced.
It may be time to look for a newer model.
Amazon’s current e-reader lineup contains several excellent Kindle options.
