Computer Crash, Power Surge USB

Downloaded 7.0.2 and iPod Shuffle Update, then put in my new iPod Shuffle 2nd Generation - worked at first, but next time I tried to plug in the USB port, the whole computer crashed. Tried it on another computer with Windows XP and got message that USB port was experiencing Power Surge.
Now every time I try to plug in my new iPod Shuffle, my computer shuts off completely.

I think you know the answer already... take it back to the store (an Apple Store, if close buy) and get a replacement. Your dock or the Shuffle's charging circuit has a short in it.

My computer says "Power Surge in Power Hub" when My iPod touch is plugged in. How can I fix this?

I have had an iPod Touch 5th Generation for a few months now. I recently updated to iOS 7. Now, when I plug it into a computer it says "Power Surge in Power Hub". It haas never done this before and when I plug it into a different computer, the same message comes up. How can I fix this?

- See:
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use. Your error message is a symptom of a bad cable
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

USB Power surge problem on my P35 Neo F

Hi,
I finally got my BIOS problems solved and have already installed everything and almost everything is ok with my system...
BUT. There is still the problem with the "Power surge in USB hub". I don't know whether this is the right forum for this but I'll explain my situation and maybe someone can help, or at least move this to the right forum.
So, first of all, when trying to do the usb flasher bios update I came across the problem where the computer totally freezes when you put a memory stick to a usb hub. That I cleared by removing the wires leading to the extrenal case usb ports, which weren't working anyhow. After updating the bios, I started working normally and thought that everything is ok with my usb wireless desktop devices and my external HDD connected. Yesterday if I turned the external HDD on, the power surge notification would pop up. Anyhow, today everything was ok until I plugged the HDMI-DVI cable for my 2nd monitor, a LCD Tv, in my computer, after which the power surge notification popped up once again. When I'm using my second monitor, it works ok for about 5 minutes after which the 2nd computer loses the signal and turns itself off. I realised that yesterday I had the same cable contacted so there must be something there.
Long story short, do YOU think that this power surge has something to do with my Akasa PSU not providing suffient power? That would sound like the most simple solution as when I contact another device to my computer, the power surge occurs, as well as the fact that the 2nd monitor, the LCD TV, turns itself off after a few minutes of signal..
OR, would it be a possibility to buy an active USB hub, which was suggested to someone earlier, for the HDD drive, which actually has an external power source of it's own. Could the external active HUB be the solution or should I just go and buy a new PSU, which would be a lot more expensive and to be honest, might not even be the solution..
I must also point out that with my previous computer, the HDD drive, the wireless desktop and the HDMI-DVI cables were always connected at the same time without any sort of problems, so could it even be a problem with the Mobo?
Sorry for my english if it's unclear, but if someone knows how to help, please do so.
Thanks!

Ok, so the best bet is that it's the PSU, I gotta start searching for one then.
Just to doublecheck, here are the voltages for my psu
voltage regulation minimum load maximum load peak load
+3.3V ±5% 0.5A 30.0A -
+5V ±5% 0.3A 30.0A -
+12V1 ±5% 1.0A 14.0A 16.0A
+12V2 ±5% 1.0A 15.0A -
-12V ±10% 0.0A 0.5A -
+5Vsb ±5% 0.0A 2.0A 2.5A
I have absolutely no idea what the figures mean, so can someone explain me the +12V voltages in this SPU, so that I won't go and buy a new PSU in vain.
Thanks in advance for your great assistance!

Has there been trouble with the charger. I am getting to re-order but the one i had the had the power surge and the end was blackened. Not sure if it safe to use the laptop again?

Has there been any trouble with the charger? I am getting ready to re-order but the one i had.... the had the power surge and the end was blackened. Not sure if it safe to use the laptop again? Thanks.

Can you also see blackening in the power jack on the PowerBook? If so, I would be worried that the surge also damaged the computer/
Does the computer run OK on just the battery? If it is working on battery power, that limits the number of things inside the computer that could have been fried.
If the computer is severely damaged by the surge, it's not worth repairing. However, a couple of posters in Apple forums said their homeowners'/renters' insurance paid them replacement value of their computer after power surge damage due to known problems on the grid, like the huge power outage that hit the SW Untied Stats and part of Mexico yesterday.

IPOD Shuffle not recognized by computer, and caused a USB power surge

Device is not recognized by computer, and I tried the listed support recommendations.
The problem originated when I plugged the IPOD shuffle directly into the computer USB ( not using a hub), and this caused a warning window to appear saying unknown device has caused a power surge to this port, and most be removed. Prior to this event, the IPOD shuffle has worked (with direct contact with computer usb or through a powered highspeed usb hub) without issue for nearly 1 year. Any taker's on this issue? Thanks.

Hi JBR,
Go to your control panel and click on Install/Uninstall programs. Scroll down and see if you have multiple versions of the ipod updater installed on your computer. If you do, then uninstall both versions. Reboot your computer.
Next, go to the downloads page and download/install the 1-10-2006 ipod updater. Once installed, go to your start programs and select ipod updater from there. Plug in your ipod and wait a moment. If it's like mine, it'll recognize your ipod and then you can do a "restore" for a clean format.
After that, open itunes and life should be good.
Hope this helps!

Power Surge on the USB Port.

Well, for the first time ever in my 2 years of having this IPOD plug for my 5th Gen...I wanted to upload some pics on my ipod, but i plugged the port into the computer and the other part into my ipod, and it said my port had a power surge of some sort. So i can't charge my ipod via computer, but it works in my ipod player (which is my deck that i have in my bedroom to play music through speakers) and it works...And other USB items (i.e webcam) work in any port...So its seems its just the plug.
It all of a sudden worked when i just plugged it in as i wrote this to be sure what it said, but does anyone know why this happened?

When you say "port" do you mean the iPod cable that has a dock connector on one end and a USB connector on the other end? When you have your iPod connected to your iPod player does the player have a dock connector on it such that the iPod plugs directly into the player? If the answer to both of these questions is yes then I would suspect that the iPod cable is bad or on its way out. Another test of the cable would be to connect it to an iPod power adapter that plugs into the wall and see if the iPod charges.
The other possibility is that there are other USB devices connected to your computer and when the iPod is connected the USB ports on the computer are unable to supply sufficient power to all of those devices.

Power Surge on USB hub port

I bought a Nano about a month ago. When I first hooked it up to my laptop, it worked fine. Now I can't get it to even connect. When I plug in the USB cable to any of my USB ports (with or without the Nano attached), I get the pop-up on the task bar that says there is a "Power surge on the USB hub port" and that I need to reset the port. I am assuming that there is some setting somewhere that needs to be changed, but I just can't find it in any of the Apple Support pages on the web.
Does anyone have any ideas for me?
Thanks,
Jeff

Hi - Had the same 'Power Surge on USB' problem - thought it was curtains as I could do nothing to get my 18 month old nano to sync or even charge from my computer. I did however manage to get it to charge from the mains with someone elses charger so I tried their sync cable into my computer and - hey presto! - everything back to normal! Then re-tried my sync cable and again 'Power Surge.....' - so maybe a new cable is the answer - hope it works for you - Good Luck

USB power surge??

Whenever I connect my mini to the computer it comes up with USB power surge balloon and i clicked on it and tried to fix it but that didn't help. i've tried a self powered hub and 3 different cord and reinstalling the software but nothing seems to work....HELP!!!

Are you plugging into a port directly on the computer or is it on a usb hub? The port you plug into must be powered in order to charge the ipod. If it is a hub then the hub needs to have its own plug in power supply. The ports directly on the computer should all be powered, if the one you are using doesn't work then try a different one.

IPod Shuffle (2nd Gen) ruined onboard USB hub (Power surge on hub port)

A user that I support fried his onboard USB hub on his laptop by plugging in his new iPod shuffle. Before doing this, everything else worked, but now, no USB devices will work.
When he tries to plug in his wireless keyboard/mouse receiver, it says "Power surge on hub port" as a popup balloon (this is Windows XP Pro) above the system tray. When he clicks on it, it says:
"A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device.
(The location of the device is shown in bold type)
To reenable the port, disconnect the hardware and click Reset. If you click close, the port will no longer function."
Options: Reset, Close
Neither resetting the port nor rebooting the computer will resolve this problem. Most USB devices are not recognized at all (Windows does not respond to them and they are shown as Unknown Devices in the Device Manager).
This affects not only the USB port that the iPod Shuffle was initially connected to, but all the USB ports on the computer.
From everything that I can tell, the USB hub built into the motherboard is fried and needs to be replaced.
Has anyone else had this problem?
Is this something that Apple will admit to and pay for?

I called Applecare and they claim that an iPod Shuffle could not have done this because it never sends power over USB, but only charges. They said to contact the manufacturer of the computer.
I am not convinced of this claim, however. Possible defects in the product could still cause this, such as it creating a short circuit and having power channel from the USB hub back into itself.
This is just off the top of my head, but can any of you think of another explanation?
The timing of everything working before the iPod Shuffle was connected and nothing working after it was connected lays the blame squarely upon the iPod Shuffle. If there had been an issue with the motherboard or its USB hub, it would have shown up before; other USB devices that draw significant power never triggered such a hypothetical defect.
If anybody has another idea how the iPod Shuffle could have done this or knows of a way to convince Apple to take this seriously, please let me know.

HT4061 How do I restore my iphone 4? Whilst updating to new software my computer crashed. This has left me with a phone that won't respond at all and itunes says 'restore your phone'. I can't press anything without getting a picture of a usb. not useful.

My computer crashed while updating my iphone 4.
My phone now will not respond other than a USB symbol to itunes.
When I plug into itunes it says 'reset your phone'.
I've tried holding the on/off and home button together, nothing.
On another note, it isn't possible to schedule into a shop in London until a week today. There is something seriously wrong with this picture.
Any help would be awesome.
Thanks

1) ensure iTunes is authorized for your iTunes store account(s)
2) connect your device and right-click or control-click it in the iTunes Source list, then choose transfer purchases from the shortcut menu that appears.
3) sync the device
iTunes will wipe the iPhone but, since you transferred your purchases in the previous step, your content will be in your library and you can re-populate the iPhone with it.
above works for purchases from the iTunes store. for everything else, check out this post by Zevoneer.

In the process of saving a file a power surge rebooted computer. Any chance of recovering file?

In the process of saving a file a power surge rebooted computer. Any chance of recovering file?

Have a look at the sample script below. The "while" loop waits for the specified number of milliseconds, then reads the contents of a directory and processes every individual file in the directory. In my example, it just prints the file path to the console. You would replace this part with your Open / Save as / Move sequence.
For more file system commands, refer to Adobe's Javascript Tools Guide, "File object functions".
var stop = false;
while( stop==false ) {
    // Wait for 20.000 ms
    $.sleep(20000);
    var fld = new Folder("c:/incoming");
    var filesInFld = fld.getFiles("*.fm");
    for(var f=0; f < filesInFld.length; f++) {
        // process the individual file
        $.writeln(filesInFld[f]);
    // Exit the loop after 19:00
    var time = new Date();
    if( time.getHours() > 19 ) stop = true;

I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this?

I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this? It bugs me when I'm looking at real estate.

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

everytime i go to plug my ipod 5 in with the charger in to the mac desktop computer a message says "USB DEVICE DISABLED" "unplug the device using to much power to re-enable usb devices" and ever since i had got that message my charger had stopped working even plug into a wall outlet
ps.its my only charger and i need to know if i can fix this problem or my mac broke my charger

Hey HoustonSmith, using to much power generally means a short. Do not use this cable, the lighting cables have a history of failure; shorting out. If within one year of purchase date take it to Apple, the cable also has a one year warranty, if short is do to manufacturing flaw and not abuse Apple will replace it free! Otherwise a new cable is around $30. You could also try a reset or restore, but don't think a glitch is your problem. If you do try to restore, just remember to make backup copies of all the info / data on this iPod to your computer first, then attempt to restore. Good luck. Cheers.

Power surge to a USB port

I plugged my brand new iPhone 5 USB cable into my laptop and it displayed a message about a power surge to that port. i dismissed the message and removed the cable. Now none of my USB ports are working.

Are you using an official Apple wall charger and an official apple usb adaptor? Some of the unofficial ones have been known to do that. If it's an official one take it down to the Apple store to get a replacement. If the problem persists it could be related to your phone.

IPOD causes a power surge on every port on the computer

My ipod died and was replaced with a new 40GB model. Now, it causes a power surge everytime I attach it to a port. Of course, Dell says its a problem with the ipod. I don't know what to do? Has anyone had this problem? How was it solved?

That's what I figured but I wanted to be sure. The iPod charges while it is connected to the USB port. The ports of many notebook computers and most unpowered hubs supply less power than the iPod requires - hence the message. You'll need to get a powered USB hub (one that has its own power supply). They can be found at Radio Shack, as well as just about any place that sells consumer electronics for as little as $15.
