I was using my tough book for several months , plugged into the wall, only as the battery no longer holds power---It worked fine for my basic purposes--( windows 98 !! ) occasional word processing and my music library-- I unplugged it to move, and a few weeks later tried to set it up again: the battery indicator shows power is flowing somewhere, but it won't turn on at ALL! Is there some reset button or other or some way to nudge the operating system?? the screen doesn't light up at all !!

The Apple iPod uses a rechargeable, lithium-based battery that can go between 10 and 36 hours between charges, depending on the model. You can charge your iPod using either an electrical outlet or your computer's USB port, but if you find that your iPod no longer takes or maintains a charge despite having the right connections, you should try some basic troubleshooting methods to restore the device's battery life.

Connect your iPod to a different USB port or wall outlet. If you use a USB port to charge your iPod, you may simply have a low-powered port, according to Apple. You can often resolve this by switching the cable to a different port, or using a wall charger (sold separately) to recharge instead. Charge your iPod for several hours. If you find your iPod completely unresponsive even as it charges, leave it plugged in for three or four hours and check again. If your battery life has been depleted completely, the iPod will need time before it can begin functioning again. Restart your iPod. A frozen or dysfunctional iPod may fail to charge, but a quick reset can fix basic functionality glitches. To reset a touch-wheel iPod, hold down the "Select" and "Menu" buttons until the gray Apple emblem appears on the screen. For iPod Touch, hold down the "Sleep" and "Home" buttons (the only two buttons on the device). Connect your iPod to your PC using the provided USB cable, open the iTunes software and click the "iPod" tab in the left column. Then click the "Update" button to search for and install the latest iPod software. Apple recommends keeping your software up-to-date to ensure that your battery life remains fully optimized. Purchase a new battery from Apple. If your battery fails to charge despite all your troubleshooting efforts, it may simply be too old and depleted to continue functioning. By taking advantage of Apple's iPod Out-of-Warranty Battery Replacement Program (see Link Below), you can send in your iPod and receive a replacement battery or replacement http://www.apple.com/support/ipod/service/battery/ iPod for a modest fee.

either dead battery or burned out power supply try buying universal one from radioshack or best buy make sure you can return it if its not solving the problem.

Hi,
There are probably a few capacitors on the power board that have defective formula and will need replacing. If you have some basic test equipment and a basic electronics background I can walk you through some troubleshooting steps. Otherwise if its still under warranty take it back, if not you can consult your local TV repair technician. CLICK HERE to find TV technicians in your area just enter your zip code.
And of course always check the basics first by making sure the wall outlet that the TV is plugged into is working. Check the ac cord, make sure its fully connected to both the wall outlet and the TV ....etc

Basically it seems like a battery problem because as long as there is power delivered to the player it is working. When taken off the power source it becomes dead. Try changing the battery. Hope it should work.

You can purchase new one from amazon LeapTV Educational Active Video Gaming for Kids. I hope this was helpful. cheers

Try holding the power button longer (10-30 seconds). Also, ours does not hold a charge for very long when not used (maybe a week?) try putting it on the charger again.

I too had the same problem with my My Book Essential and I actually got it to work...
I had tried to plug it into my PC and low and behold it didn't power up, the light didn't come on and there was no activity whatsoever so I began with the process of elimination starting with several different chords both power and USB.. Nada! Then I took the case off to see if the power adapter was loose on the board.. Nope! Then I used a Voltage tester on pretty much every where that could be checked and the power board was fine, although I couldn't get a reading from two of the pins that goto the actual part that plugs into the board attached to the drive. Then I went on to test that board and there was no power going to it... in fact there was no power in either board when they were connected together. The power board only had power when it wasn't connected to the drive board.. I gotta say I was stumped!! So from there I decided to open up my PC, unplug my cd rom drive and use those connectors to plug in my My Book and the drive worked... I got a fat 32 warning message but continued anyways and the drive powered up and all was great!! I had access to the drive like normal. I then thought hmmm lets try and re attach the power board and see if it works.. and it did! It's back in it's case and working fine.. Don't really know what the cause of the problem was but it did fix it so I hope this helps some or all of you. But please know that I NEVER had any clicking noise like some of you describe.. Just had no power... Good luck

This is usually caused by a bad battery. Sounds like both batteries are not working properly. They may still hold some charge, but they are wearing out. After all, they are batteries, and bateries wear out. Keep in mind that some batteries are better than others, even though they may be the same brand, some will hold a charge longer, and some wear out faster. I'm on my second new battery in a year and a half on my Dell, the first held a great charge but wore out after approx 8 months, the one I'm using now still charges fine but only last about an hour and 15 mins.
