Paperwhite Kindle Cover, How to add a magnet to wake
This post is about how upgrade a cheap case to enable the automatic on feature of the paperwhite Kindle.
As the previous post described, my Kindle broke and I bought a Kindle paperwhite 3G. Since my previous Kindle screen broke the second day I had it (that time warranty covered it), I learned that the screens are very fragile and you need to keep it in a case.
Already smarting from the price of the Kindle, I didn't want to pay $40 for an "official" case. I bought the $12 one below instead. Which would you buy? BTW the $12 one is very nice, I'd recommend it.
OK finally to the only interesting thing in this post. The big difference to me between the $40 and the $12 cover was the magnet in it that automatically unlocks the Kindle when you open the cover. I first thought, who cares, but the power button is awkward to find and push each time. I had read about it as a feature so I experimented to figure out how it worked.
I cut out a section of a sheet magnet that was from a file cabinet label. Probably could have used any refrigerator magnet. Here is an example of the type I used. I didn't buy this exact one, I used a magnet that was lying around.
With the magnet in place, when you open the cover, the Kindle acts as if you pushed the power button. You still have to swipe to unlock the screen but that is much easier and natural than fumbling around for the power switch on the bottom.
You may have to experiment a bit to find a good magnet. However at first it didn't seem to be working when I was doing it by hand, but in the case it worked much better. The motion of opening the case seems to be important.
I used double stick tape and cut a section of sheet magnet and put it in the lower left of the case cover. When it folds it lays on top of the lower right of the Kindle.
I've been using the case this way, with the bit of magnet double stick taped in the corner of the case for a few weeks now, and it has been fine. Every time I have opened the case the Kindle wakes up. The extra depth of the magnet in that corner isn't hurting anything.
For a more permanent solution is you could hot glue a button magnet or cut a recessed hole. You can scrounge these sort of magnets off the back of refrigerator magnets, but here are some tiny ones for a couple bucks.

Here's a link to one I found on Amazon that's around the same cost as the one you listed. It already has the magnets as well as a palm strap. It's a perfect secure fit for the Kindle Paperwhite!ReplyDelete
Which cover do you have in the picture? I have done some research and the covers with magnets somehow conflicts with Kindle on/off feature sometimes it turns it on/off without even opening the cover so I prefer using the above cover without magnets but I couldn't find any yet please give me a link or the info about your cover.ReplyDelete
The left hand "buy from Amazon" with a picture of the jkase is a link to the page where I bought it. Don't worry it doesn't make you buy it, just takes you there.ReplyDelete
I converted my old kindle cover to do the auto wake but I did have to remove one magnet from the right corner and leave the one on the left as when touching both magnets seemed to turn it off and keep it off even pressing the power button. So it seems one magnet on the cover which meets the right bottom corner of the Paperwhite did the trick.ReplyDelete
