Is your Kindle feeling sluggish? Does it seems like it takes a little longer to change the page then it used to? That doesn't mean there's some technical problem. It means it's time to reboot it.
Anyone who has ever used a computer is well aware of the "turn it off and back on again," IT joke, but a number of people have told me they're thinking about buying a new Kindle because theirs is getting "slow". It seems silly to even mention this because it should be common, but Amazon tucks the restart option so deep into menus that it's a troubleshooting tip worth mentioning.
So, the next time your Kindle feels a little slow, whether that's taking forever to wake up or the pages seem to flip a little sluggishly, restart it. From the Home menu, tap Menu, then Settings. From the Settings Menu, tap Menu again, then tap Restart.
