I can't turn the Kobo Reader off!

I know the solution is going to be really simple but I at my wit's end. I simply cannot get the reader to stay turned off. When I'm reading a book and press to Power button to turn it off the cover of the book comes on the screen and stays there. If I press Power again it goes into reading mode. Pressing and holding the Power button down does not do anything differently. I'm worried I'm going to burn an image into the screen.

So, please help! How do I turn this off, or do I have a defective unit?

Thanks in advance,
Dorey

That's one of the features of the Kobo eReader...when you power down the unit, the cover of the last book you were reading comes up. It's not a defect, that's how it's supposed to be.

The simple beauty of e-ink. Basically the unit is off whenever it's not in use. Whether you use the off switch or leave it on the table at the page you were just reading, it's off. The only time it is 'on' and therefore using battery power is when you turn a page, download a book, or make it do something by way of a menu command. The book cover is just it's way of saying you've closed the book for the time being...cool, huh?

Thanks very much for such quick responses! I agree, it is cool that it shows the book cover when the unit is off.

That's not entirely true. What is true is that the screen requires no power to hold an image. There is, however, still a difference between "on" and "off". When it's on, there's software running on it and at least a small "trickle" of power keeping the RAM alive. Some readers (like Sony) have a "standby" mode where the screen goes blank (when you flip the power switch) but the "trickle" is still there - it means your book loads in less than a second when you "turn it on" (vs 35 seconds with Kobo), the downside is that it is (slowly) draining your battery.

But yes, with the Kobo, when you hit the power button and it shows the cover, it is fully off.

That makes sense and I see the difference between that and the Kindle. I've been switching off; I think I might be inclined to select "Overview" instead and leave the juice running. Even if that slices a few days off between charges -- 12 days instead of 14 -- I won't fret.

That does make sense. I had wondered why there was even an off switch in the first place. It is nice to know that it only trickles the power away...so, when I fall asleep with it still on, I don't have to worry much. Thanks for the info!

Just make sure you don't dribble on it whilst asleep

I've noticed some image retention too but the image seems to only stay for a couple seconds after turning it on and then washes away.

Will keep an eye on this though, burn in would be very upsetting.

Burn in is not possible with E-Ink.

There's definitely some power draw if you DON'T power off the device.

Peace.

I didn't know enough about the technology to know if burn in was something to be worried about. Would have helped to have a small blurb about that in a proper instruction manual
