Just purchased a Kindle Fire HD7. Start up instructions say to charge battery by plugging device into power adapter via USB cord. Is there another way to charge device since I have no plug which fits the adapter?

Hello

If the battery isn't too far gone, here's how to revive it:

1.Plug the device into the Kindle A/C adapter (not your computer) and let it charge for a few hours.
2.If you still see the same Critical Battery screen after charging, unplug the USB cord, then hold the power slide to the right for at least 20 seconds.

Reset the Device:
If your Kindle Fire won't move, this doesn't necessarily mean that it's "broken" or has a major problem. The Kindle Fire has a tendency to become "stuck," meaning that it looks like it's "off" when it's actually "on" but it will not work properly because it's locked up. To unlock the Kindle Fire, do a reset by holding down the power button for 20 seconds or more. Then turn the device back on by hitting the power button again. If this doesn't work the first time, try holding the button down for 30 seconds or more. Most of the time, this will be all you have to do to get the Kindle Fire up and working again.

Charge It:
If resetting doesn't work, it's possible that your battery is dead. Try plugging the Kindle Fire into the charger and wait about 15 minutes before trying to turn it on again. If the device refuses to start up, try resetting it again.
If it still won't move, it's possible that you have a dead charging cable. Alas, the cables that come with the Kindle Fire are not known for their longevity. Try charging the tablet with another cord that has a Micro USB connection and see if the device responds. There's no guarantee that the charging cord from your smartphone will work with the Kindle Fire, but it's worth a try. If you get a bit of a charge, then you'll know that your Kindle Fire needs a new charging cable.

Try a Different Power Source:
if the charging cable appears to be working but the tablet still won't move, try plugging it into a different power outlet or the USB port on your computer.
If all of these troubleshooting tips fail, your Kindle Fire may have a hardware problem that requires professional help.

If the battery isn't too far gone, here's how to revive it: Plug the device into the Kindle A/C adapter (not your computer) and let it charge for a few hours. Be sure the charging light is lit -- sometimes a drained Kindle will stop charging a few seconds after you plug it in. Unplug and replug until the light stays on steadily, then leave it alone. Most of the time you'll come back to a restored Kindle. If not, go on to step 2. If you still see the same Critical Battery screen after charging, unplug the USB cord, then hold the power slide to the right for at least 20 seconds. Release the power slide, then immediately press and hold the Home key for another 30 - 45 seconds. Once the Kindle's screen begins to flash, release the Home key. The eReader will boot to recovery mode. To continue, press and hold the R key until the screen flashes again. After the device is finished rebooting, you may see the Critical Battery screen once more. If so, plug in the USB cord and wait for the Kindle to return to the Home screen. - See more at: http://www.laptopmag.com/articles/kindle-critical-battery-error#sthash.Rtxwp4El.dpuf
