If the keyboard has a round purple connector, power down the computer then unplug and then plug in the keyboard. Power on the computer. If it works your done if it doesn't replace the keyboard. If this is a USB keyboard, with the computer on, unplug and plug in the keyboard if it works great, if it still isn't working replace the keyboard. NOTE if this is a multi functional keyboard (special keys at the top) make sure you install the driver and any software associated with the keyboard.

Second outlet may still be on same circuit. Check the breakers to be sure, or plug in a lamp to check the outlet.

Use a card reader. Since your computer has a USB port, you can get a card reader that reads SDHC cards. This is exactly how I do it on my computer.

• This isn't an iTunes problem. While the iPod is displaying this logo, you need to plug it in to a computer that has iTunes open beforehand.
• Try using another computer with iTunes installed, or another USB cable for the iPod. Try to restart by holding the sleep and home buttons for about 10 seconds.
• If this still doesn't work, take the iPod to your local Apple store, where they can check for any hardware problems that may have occurred.

Make sure to try different outlets in your house to ensure its not the outlet that is broken. Although I'm sure you have already tried that. Other than that there isn't really anything you can do, it probably got shorted out. You may be able to take it to some kind of electronics repair shop and see if they can figure it out, but I'm guessing your best bet will be to buy another.

Hopefully this helps

The battery only works when it isn't plugged into the wall. That's what a battery backup is for,so when the power goes out, the battery kicks in.
