Remember 2012, when everyone was banging on about how good Kindles were? And then you got one, because you thought it might be good for commuting, and holidays? It was good wasn’t it? So light! So user-friendly! Well, it’ll also be next to useless tomorrow (March 22), unless you perform this crucial update.

The issue affects every Kindle made before 2013. If you own one of these and you don’t update its operating system today, you will no longer be able to go online with it, which means you won’t be able to sync it, or use the store, or download new books. For those whose Kindles have been relegated to holiday duty and are just lying in a drawer somewhere, the next time you turn it on it’ll just be a time capsule of what you read last time you went to Spain.

To fix it that issue easily, you just need to plug it in today, turn it on, and click ‘sync and check for items’ in the menu. If you don’t do it before tomorrow, things get a little bit more complicated – and you’ll receive this message: “Your Kindle is unable to connect at this time. Please make sure you are within wireless range and try again. If the problem persists, please restart your Kindle from the Menu in Settings and try again.”

In that case, you’ll have to download the right update for your device from this Help page and manually install it via a USB cable. But that’s a right faff.
