Kindle devices allow you to load non-Amazon files onto them; you can copy them directly to your device using a micro-USB cable, or have them sent to your device wirelessly, through Amazon's Kindle Personal Documents service.
You are limited to the types of files supported on the Kindle: at present, these are .azw, .azw1, .txt, .mobi, and .prc. In addition, ...
While impossible for me to find on my own, an external link brought me to this page by Amazon with hints as to how to identify which of the many Kindle models you may have:
Which Kindle E-reader do I have?
From the blog post, How to Tell Kindle Paperwhite Generations Apart, I learned this:
The first Paperwhite has big “Kindle” logo on back, versus “Amazon”...
From the tags on this questions, I'll guess that you're talking about a Kindle Paperwhite. I know it's possible to do this on a Kindle Fire as well; it's in Settings > More > Display > Screen Timeout there (screenshots here).
On the paperwhite, and apparently many of the other Touch devices, there are commands that you can input in the search bar to do all ...
Have you tried tapping on the bottom left corner of the screen while reading a book? You can switch among various options:
%, time left in chapter
%, time left in book
blank (ie, your current state)
From the manual, it tells you that if you purchased the device through Amazon then they use your Amazon account information and register the product to you before they ship the device. Definitely not mining your wireless AP :)
Registering your Kindle
If you bought your Kindle online using your Amazon account, it is already registered to you.
I have found the best way to get it 100 percent working is this:
If your book is not already in AZW3 format then convert it. (Has to be AZW3 and not just AZW.)
Secondly, highlight the book and edit metadata.
Once you are at that screen delete any other format that you have shown in the top right side leaving only AZW3.
Delete the tags by hitting the recycle ...
This appears to be a known issue with the Kindle Fire. I'm assuming it is also an issue for your model. I would suggest that you just broadcast your SSID. Most people report this is fixes the issue. If you are not broadcasting it for security reasons, that is what encryption and password are for. If someone wants to break into your network, hiding the SSID ...
TL;DR: Yes, there are some risks.
The ereader could transmit a virus from the PC to another PC, if you plug it into another PC. It could receive an infected file from the PC, then reinfect the PC the next time you plug it in, even after you clean up the PC. Or a virus on the computer could damage the ereader somehow. I have never heard of any of these ...
Get the Quality Check plugin for Calibre and then use it's "Fix -> Fix ASIN for Kindle Fire" feature. It expects that you have the Amazon ID in the book's metadata somewhere, which should be there if you download the metadata using Calibre. This inserts the ASIN and allows goodreads integration to work. I tested it myself.
One annoying thing is that it ...
Additionally, there are some USB cables that are with charge-only feature. They have less pins, usually a lot cheaper or come with devices that are not made for a pc-device storage connection. For example, a Chinese cable for 0.99$ or a cable that came with a portable charger (power bank). I've come across quite a few of these in my life, they will not work ...
From the User's guide:
Understanding Kindle display technology
Your Kindle uses a high-resolution display technology called electronic paper. The
display is reflective, which means you can read it clearly even in
bright sunlight. Electronic paper uses ink just like books and
newspapers, but it displays the ink particles electronically.
The PDF file format does not support cover images.
PDF was designed to show a faithful representation of printed pages.
Reflowing text to other page sizes typically is not possible; you should use PDF on an ebook reader only when the page layout is important.
The Paperwhite uses a Carta e-ink screen with a contrast ratio of 15:1 however, here's a German test that says the contrast actually is 12:1 (assuming Google translate was accurate -- my German is horrible). It has comparisons with other models, too.
The Kobo Glo uses a Pearl screen with a contrast radio of 10:1
Here is an older comparison of the two ...
I don't think they make an app for the PaperWhite since it would appear it is Amazon content dedicated and not based of Android because I recall being able to install error logging apps from Android on my Kindle.
Since this is a DRM free book I would omit the usage of Calibre. That said I would download Kindle Previewer and browse the book for any ...
Well OK I somehow found the answer myself. The problem of Chinese fonts not updating is not because of my registration at US Amazon, but because of my system font not being Chinese. As soon as I changed my font to Chinese it almost immediately started the font update.
The best way is to contact the Amazon support. If your Kindle is still under warranty they will replace it free of charge. If it is not we might to try help you but you must provide us some extra info like error message or photo of error.
I searched all over and could not find the solution until I came across a russian site http://kindle.zzweb.ru/paperwhite/repair/. Basicly it sates this:
Connect the Kindle Paperwhite to a computer USB-cable.
Create an empty file in the root directory DO_FACTORY_RESTORE.
Safely disconnect the reader from your computer.
Reboot your device by holding the power ...
Ok I found a solution for my problem:
My kindle 4 non touch fell down from the table, and I had the screen "your kindle needs repair" and I did as above with DO_RESTORE_FACTORY, after that it was worse I had the reboot loop and the kindle needs repair screen switching.
I had nothing else to lose so I opened the back cover of my kindle, I found the little ...
An alternative, which at least gets round "kindle is slow" is to use the Kindle app, on e.g. Android phone or tablet, if you have one, to manage your collections.
The Android app does support the new-style "cloud collections", as used by the PW, Voyage, etc.
The advantage here is that it is much more responsive, both in screen display and touchscreen ...
To defragment a filesystem you need a software that does that.
All you have to do to defragment the memory of your Kindle Paperwhite is to connect it to a PC/Mac and run a defragmentation utility on that drive.
Edit: Being a flash drive though, as @Daniel suggests, it's actually not a good idea to defragment it, because there will not be any real benefit ...
If you are comfortable making HTML from your Word documents, I was able to print Hebrew text strings to Kindle KF8/Fire (phrases, not whole documents) using HTML with CSS tags.
font-family: 'Hebrew', serif;
In your HTML, you need to call the .hb class in your P ...
The largest security risk is basically the same as that of a USB stick. By plugging the device into an infected computer, the file system on the device that mounts just like any other removable storage device could be written to and mal-ware loves to piggy back on portable devices. When you later plug the reader into another computer, you could infect that ...
The simple, answer is that you export the PDFs to files on your disc and then use the add books function of Calibre to add them (or drag and drop) to get them into Calibre.
Any files that have DRM you will not be able to import and read, but you should continue to use these on ADE. Removing the DRM is probably against the law.
Once you have the files ...
Apparently the Voyage rendering system is similar to the Paperwhite, but not the same.
I (currently) know of one difference between the two; there is a rendering bug in the Voyage that the Paperwhite does not have, as described on the MobileRead forums:
let's not forget that Voyage has that weirdo width bug, too, for
images? Not the same, mind you......
Got an epub book? Best way at the moment for most qualiity and support is renaming to .txt (or png?) and sending to kindle email adress with convert subject (doesn t even need convert subject here? ; anyway better than calibre mobi conversion way). This way (direct) epub conversion is supported although it s officially not.
TL;DR (today's ...
Do not defragment any flash devices (in contrast to classic hard drives)
The original purpose of defragmentation was to reorganize data on a hard drive to shorten future paths of a read-head and therefore extending the lifespan of that drive.
In contrast flash devices do not gain any speed disadvantages of fragmented files. But flash memory wores out with ...
You don't need a credit Card to register your amazon account.
