What does it mean when kindle keyboard 3g with wifi changed battery and will not reset

SOURCE: After browsing with my kindle (3g wifi) in "aricle

Hello.

Reset your Kindle.

There's a little hole inside the battery cover area. Put in a pin or paperclip end and press. The Kindle should unlock.

Hope this helps.

Four reasons come to mind that may prevent you from connecting:

1. Wi-Fi Passwords are case sensitive. Please check again if you entered the password with proper casing and you did not put any extra white space in front or behind. I know, this sounds annoying, but it is really the most common cause for connection problems.
2. Give your network a unique SSID. This is the network name that shows up in the list of detected networks. Default names like NETGEAR can be troublesome if a neighbor one block down the street happens to have a router from the same company.
3. Some routers have a MAC address filter as a security measure, limiting service to devices specifically whitelisted. If your router is set up for this, add your Kindle's MAC address to the list of permitted devices. You can check the MAC of your Kindle from its settings page (press HOME, MENU, select SETTINGS, see paragraph headlined "Device Info".
   
4. There are twelve different standards for Wi-Fi transmission collected under the hood IEEE 802.11. The four most dominant transmission modes are called a, b, g and n. They differ in radio frequency, modulation method and data rate. Kindle supports the two standards IEEE 802.11 b and g only, which is not really a problem because all wireless routers I ever encountered support one or both of these, too. However, the WPN824v3 belongs to the "RangeMax" series of NetGear routers. In combination with certain Netgear wireless network adapters, it can be set up to use a proprietary modification of 802.11g exclusively (108Mb/sec, doubling the 54Mb/sec for 802.11g), not allowing for standard b or g connections. Make sure it allows standard b+g connections, too.

First of all there are two types of kindle, the kindle 3g + WIFI and the Kindle WIFI. If you bought the kindle WIFI you will be unable to connect to a 3g network. If you bought a 3g model you can access 3g internet by pressing the 'menu' button and then using the 5-way to navigate to 'turn on wireless'. Once wireless is on you can access your browser by clicking menu, scrolling to experimental and then selecting Web Browser

Amazon might help you with this because it is so new. However if you dropped it (etc.) and if HTC doesn't replace it for you, You can get the part at Kindle 3 Repair and there is a guide that shows you how to put in the part at Kindle Repair Guide.

SOURCE: Brightness on my Kindle Touch 3G

The Kindle 3G using E-Ink does not have a backlight therefore there are no brightness controls provided which in turn helps to increase the battery life.

If you need to have a reading light when using the Kindle then you will need to purchase one of the many clip-on LED reading lights that are available on the Amazon and other web sites.
