Yesterday I had put connected the USB charger port to my ipod to charge it. When I did this I seen it said"HUB exceeded limit" or something like that. I also noticed that the internet was off as well and I have wireless connection. I discconected everything and then shut down the compiter thinking that this will refresh everything. When I went to turn the laptop on the computer turned on but the screen was black. I restarted the computer several times, but the screen was still black. I dont know what to do anymore because the omputer itself is on, but the screen is black. How do I fix this??

Did you try disconnecting all USB connections from the laptop?
The "HUB exceeded limit" error message is telling you that you have too many things using too much power on your USB connections.

Please disconnect all USB connection, disconnect the power cord, and remove the laptop battery. Next press and hold the power button down for 30 seconds to drain away any residual electrical charge from your system
Install the battery and plug in the power cord again -- do NOT plug in any USB connections at this time.

Try to boot the laptop as normal. If the laptop does not boot as normal now, then you will need to take the laptop in for service.
If it does boot normally, only plug-in the USB adapters that you currently need -- one or two at a time in order to prevent future overloads.

If you absolutely need all of the USB devices plugged-in at the same time, then I suggest that you buy an powered USB HUB to plug all devices in to.

It sounds like the supply to the USB and motherboard has been overloaded and the fuseable link has failed.
It, unfortunately, is a job for the specialist as there are a lot of components that could be easily killed if static precautions are not adhered to and of course recognizing the faulty component, removing and replacing it etc.

Why isnt my ipod charging?


iPod's battery doesn't charge


Several things could keep your iPod's battery from charging. The major causes are listed below in logical order. Check each one to see if it's what's keeping your battery from charging.


Low-powered USB port

iPods that connect to USB ports require a high-power USB port.

Keyboards and some USB hubs will not charge iPod. Connect iPod directly to the computer or to a USB AC power adapter. Click here for more information.

Connect directly to computer

If you connect iPod to something that connects to the computer (like a USB hub or FireWire drive), connect iPod directly to the USB or

FireWire port on the computer.

FireWire port on a Windows PC

The FireWire (IEEE 1394) ports on some Windows-compatible computers may not be powered, and consequently won't charge iPod when you plug it in. Check here to see if the FireWire port on your PC can charge iPod.

Your computer goes to sleep

Your computer can only charge iPod when it's turned on and not asleep. Make sure your computer is on and not set to go to sleep when you want to charge iPod. Tip:

Some Macintosh computers can charge iPod even though they're asleep.
If your sleeping computer doesn't charge iPod, don't worry, just wake it and let iPod charge.


hope this helps

<p>When you buy an iPod, the device comes with cables that connect the charging device to the computer. When the iPod battery is low, you can recharge by plugging into your desktop or laptop. But sometimes, when you connect your iPod to your computer, the battery charger. According to Apple's site, some problems may prevent your iPod from charging properly. <br /> <p><br /> <p>1. Connect your iPod USB charging cable only one USB port on the computer itself. External port devices, such as a USB hub, do not provide enough power to recharge your iPod. <br /> <p><br /> <p>2. Connect the iPod firewire charging only one firewire port on your computer. Like USB, Firewire ports are not enough of a load to the battery of your iPod. <br /> <p><br /> <p>3. Disconnect the computer from sleep when the computer set to sleep after a certain time. An iPod can only load on a computer that is connected and not in sleep mode. To enable sleep mode on most computers, you can move the mouse or press the power button once. Hold the power button, which usually turns off the computer. <br /> <p><br /> <p>4. Turn the iPod off and on when the unit is frozen. A frozen iPod is not charging. If the unit is still frozen when you turn it on again, restart the iPod by pressing the "Hold" switch to "On" and then back to "Off" and press and hold a "Menu" and "Select" buttons simultaneously or " Start "and" Menu "button. Hold the buttons until the Apple logo appears on the screen. <br /> <p><br /> <p>5. Set the system up-to-iPod charger so that when using a Windows 2000 computer. In preparation for the system to load the iPod device to the unit with the charging cable, launch iTunes and "iPod" in the left pane to "Settings" tab to go, check the box next to "Enable Disk use", and click the "Apply" button. Once the configuration is in place, the iPod will charge as normal. <br />

A usb has exceeded the power limits of its hub port


Simply put its what it says.

you have too many devices drawing power from the USB ports of your laptop.

A fix for this is to use a USB hub but it MUST be one with its own power supply.

A USB device has exceeded the power limits of its hub port


Windows display this message when a USB device is short-circuited. Try another USB cord or connect the usb to the port at the back of your pc. If it does not help then the problem resides in the printer. I will not suggest to dismantle your printer as there are no user serviceable parts inside.
