Intel Mac :: Apple Wired Keyboard Allegedly Drawing Too Much Power
Mar 13, 2012
Whilst working on my iMac as per normal, I get this little window that pops up declaring that a USB decice is drawing too much power from my computer and as as a result, one or more of my USB devices has been disabled.
This is not an alien dialogue box to me, I have seen it many times. The problem this time is that, when I removed all my devices to see which one was causing the message to pop up, I discovered that it was my keyboard that was misbehaving.
When the message pops up it states that the offending device has been disabled. This cannot be the case however, as I am able to press enter to close it, and if the keyboard truly is the problem then I shouldn't be able to close it with enter because it would have been disabled... right?
Wondering if anyone else has had this problem. My keyboard is the standard wired + number pad one shipped free with new iMacs. It's not a custom one, it's apple stock through and through.
The baffling thing is that this has only just occured. In the year or two since I bought my iMac it's never been a problem.
Yes I have tried using a different USB slot, and no that doesn't fix it.
This box keeps popping up unless I disconnect my keyboard which of course is no way to use the computer, and I don't have a spare keyboard handy.

Well, I just recently received a used wired apple keyboard, but whenever I try to plug it into any USB port, I get the following error: Even when I unplug every other USB device, I get this error. I'm using a Mac Mini.

A number of times now my Apple brand Wired Keyboard has droped out of control. The letter keys work fine, but things like enter, return, the volume keys and more everything in that line will not operate. OF course, then waking it up from sleep becomes a problem and to get that back or any of the usual control I need to restart.

I just purchased a brand new wired keyboard from apple for my imac G5, I was told it would work with what i have running, leopard. I followed instructions, plugged in
and checked for upadates, there was none, but the volume button is not regonized, the volume button instread brings on gadgets, or make the gadgets leave, in other words, some keys work for something else, or not work at all.

This is my first post on the forums, although I'm planning on looking around in here once in a while, to see what people are posting.
For starters, I just wanted to tell you about this little problem I've been having with my MacBook 1,83GHz.
Sitting at my desk at work one morning, peacefully drinking my coffee, I suddenly received a rather discomforting error-message from my shiny new (about 1 month old) MacBook;
"A USB devise is currently drawing too much power and the port will be deactivated.".

I want to get the apple wired keyboard (not the wireless), but I'm undecided on which version. Is the shorter wired version a lot more cramped than the longer one, in respect to the majorily used keys, or is the spacing the same between the characters for both keyboards. I never use a num pad normally and would like to free up a little space on my desk, but I'm worried that the rest of the keys will be more cramped and uncomfortable to type on.

Does anyone have any idea / images of how the magic trackpad sits next to the Wired keyboard from Apple. It looks by the images that the wireless keyboard is slightly more angled than the wired version. Just wondered if anyone has any pictures of how the trackpad sits next to the wired keyboard?

I bought an iMac on dec, 2010 it came with snow leopard and a wired aluminum keyboard, everything was good until dec, 2011 when my keyboard suddenly stopped working, I took it to an apple store and they replaced it, everything was fine until last month when my new keyboard stopped working again.
I have an old macbook (1st gen of intel-based macbooks) and if I connect the keyboard to that macbook it works just fine, I have checked and all the USB ports on my iMac and they work but when I connect the keyboard it just doesn't recognizes it as a keyboard (or as anything because it doesn't show on system profiler). I have connected another keyboard I own (a logitech wireless one) and the imac recognizes it, I don't know what to do.
Btw, if I disconnect the keyboard for a day or two it works again when I connect it to the iMac, also If I use the USB ports attached to the keyboard I get an error that the USB is taking too much power and it shuts down (and then the keyboard stops working again on the iMac)

Just recently, I keep receiving an error, every couple of minutes or so, thats states: "A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated." Now I have seen this same problem posted, but I have No Device hooked up at all. I have a 2 year old macbook pro 2.4 GHz, running 10.5 I've tried rebooting but it continues to occur.

I've just bought a Mac mini to use as a media centre, and I picked up the Apple wireless keyboard and mouse while I was at it. It wasn't until I got home that I read the "requirements" section on the side of the mouse and keyboard boxes, where it states that an existing keyboard and mouse are needed for setup.
I have a USB mouse, but no keyboard (my other Mac is a MBP), and nowhere to borrow one from (all my friends have laptops).

I get this strange message every so often, sometimes more often than other times. It says:
USB port drawing too much power. The device that is plugged into it will be deactivated.
There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.

Tonight I've been transfering all my files over from my old MacBook and everytime I try to connect my IPhone 3GS by USB to my Mac a message comes up straight away saying "A device conected to your computer is drawing too much power, apple has disconected this device to prevent damage occuring to your computer"
I have tried to connect my phone numerous times while it has been conected to the power cord and also running on battery.
It also took my new Mac a good half an hour to recognise my external hard drive was connected and let me use it..
I have had this problem once or twice with the same IPhone and my old mac so im thinking it may be a problem with my phone considering it is 2 years old now?
But then again, my old mac that is nearly 4 can still connect to my phone when my new MBP can't.

I have just bought aluminium keyboard from Apple and sadly, I have the same problem described here, in this post: http://discussions.apple.com/thread.jspa?messageID=5593479
Every 5 minutes the keyboard freezes for about 15 seconds. My Mighty Mouse and tablet connected to the keyboard won't work as well. I have tried to connect it to other usb ports but there's no difference at all. Please help, as this issue is really frustrating..

I got home tonight, placed my MBP on my BookArc after plugging in the Display port adapter, USB, Firewire and Magsafe to then realise that I couldn't turn on my MBP without taking it off the cradle, opening it and pressing the on button! "This can't be right" was what went through my mind, but is it? There surely must be a way to turn on a MBP when it is attached to an Apple Cinema display and a USB Apple Keyboard while in the closed clamshell state. Surely there's a key-combination.

I just bought a new 2012 aluminum Wireless keyboard and the function keys do not work properly. I am currently running OS 1.5.8. I would expect most keys to match the icons on the keyboard. I do not want to upgrade to Snow Leopard or Lion. I have installed an aluminum keyboard upgrade 2.0 and this did not help. I just want the the keyboard functions to match the icons on the keyboard.. Volume up...volume down...

I'm one of the $200 suckers who bought an iPhone. For my $100 "rebate" I bought the new USB AppleKeyboard. I'm typing on it now. But when I first plugged it into the USB port, I got an error message like this: "The USB port is drawing too much power and it will be disabled." This is the same port the computer's original keyboard was plugged into and it worked fine. Now it's dead. The port is one of two USB ports on the back of my (original) Cinema Display. It's still dead. The AppleKeyboard is plugged into the second USB port now, and it works fine. But I thought I'd alert someone at Apple that this happened. Further, I'd like my USB port back but cannot find anywhere in the help files how to re-enable it. Unless it's fried, of course. But then again, how could the keyboard fry the port?

Can someone tell me where I might be able to get a good quality line drawing (outline) of the apple logo in vector format? I have attached a small copy of what I need but I need something I can scale to about 3/4' to 1" (a little bigger than it is) without jaggies.

Sorry to mention the 'W' word, but wondering if anyone has had this issue.
Basically Apple wireless keyboard works perfectly in Windows, but the Bluetooth power management kills it after just a few seconds, which is extremely irritating. It works after you've 'woken it up' again though.
I can't find anywhere to change this, and no joy with a forum search / Google.
