The Kindle is Amazon's exclusive e-book reader that allows users to carry thousands of books with them. Unfortunately, like most electronics, the Kindle occasionally crashes, requiring the user to reset the unit in order to get it working again. Before doing a hard reset, try a soft reset by pressing Alt+Shift+R. If that doesn't work, move onto a hard reset.
Flip the Kindle over to see the back cover.
Slide the back cover off of the unit, pressing down using your thumb and pushing outward.
Locate the reset button. The reset button is a small hole near the battery compartment.
Press the button down carefully using a paper clip. Hold it for a few seconds.
Release the button and restart your Kindle.
If you own the Kindle 2, the second version of the Amazon Kindle, reset the unit by powering it off and removing the batteries for a minute or two. Then reinsert them and turn it back on.
