My kobo keeps saying water on the screen when there isn't any

Will one of those extra battery packs work to power the kobo? I just bought a 'pocket juice' at walmart to use with my cell phone.
Others are saying it is not worth putting in the real battery.

On my kobo, I have to touch the middle of the screen to get the toolbar to pop up at the bott of the screen. You should the find the usual icon.

Unfortunately, Kobos weren't designed to replace the batteries. Short of buying a new eReader, reading with it plugged in is the only way around bad batteries.

You need to talk to Kobo technical support.

Type demo off or demomodeoff in the search bar

Clean water, I hope, otherwise chances are much worse. DON'T turn it on. Pat it dry as much as possible, then completely bury it in a sealed jar of uncooked rice for maybe 3 days. After that, try turning it on. If nothing, try charging for several hours. If still nothing, sorry!

It could be several things. But you may need to delete Kobo and reload the app. I have had to do this on some of my programs. Your books are on the net, so they won't be lost.

You may need to delete KOBO and re-install the app. Your books will be saved because they are online.

Does your Kobo turn off and on normally? Or is it stuck loading the book and totally not responding? If so, reset your Kobo. Look on the bottom edge of the Kobo - see the little pinhole? Stick a paper clip into there until you feel it push against a little switch. Remove the paper clip.

Is the Kobo working, but simply can't open a book? If it's only affecting a particular book, try deleting it and downloading it again.
