You're problem is leaving the WiFi on. It's the simplest thing to turn on and off. No need for it to be on when it's sleeping. They never shut down. They just turn off and go into sleep mode. The only way to keep a charge in the battery for any length of time is to keep the WiFi off unless it's absolutely necessary. It certainly isn't needed for reading. Only for the downloads.

What to Do If Kindle Is Frozen & Will Not Turn Off or On? Charge the Battery If the Kindle does not have enough battery power, it can freeze up. Plug the Kindle into a wall outlet and ensure the indicator light is on, which means the battery is charging. Allow the device to charge for a few minutes; then, attempt to navigate on the screen. Soft Reset If the Kindle is still unresponsive after being charged, it may need to be reset. Unplug the device from the wall charger. Move the power switch, and hold it for 15 seconds before releasing. Hard Reset If a soft reset is ineffective, you may try to reset the Kindle from the back. Charge the Kindle completely (about an hour). Unplug the device, and open the back. Locate the reset button, a small hole denoted by the word "Reset." Gently insert an unfolded paper clip into the hole, and hold it for 10 seconds. Restart the Kindle

While I don't think books in the printed version will disappear, I do think bookshops are under threat (and I work in one). So many people will come in to browse, then buy the book on line, either as a paper format or e-book. Because our market is relatively small, books in Australia are more expensive than the US or the UK, and when you can purchase from Amazon for less, people will do it. Right now the Aussie dollar is over parity with the greenback (10 years ago we were only getting 55c) and it makes it very reasonable, even with the postage (and of course no postage for e-books). I think people will regret losing a shop where you can come in and browse, check out the content of a book, read a few pages to see if you like the style. But competition is fierce and we, with a main shopping centre street front, heating, lighting, escalators and many staff, can't compete with huge warehouses in the middle of nowhere without these costs.

Got to the page with the tree. Looks like its’s loading. Hope this does the trick. Thank you Annie, really appreciate the help!
