In the last two weeks, every time I plug my Apple 27" display cables into my macbook (power, display and USB connections), I get the following error message on my screen about USB ports are drawing too much power. I don't have anything plugged into the USB ports on the back of my display.

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.".
an error message comes up when i try to plug in my iphone. it says usb drawing to much power.....?

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.

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'm using iMac with wireless mouse and keyboard.Once,I've unplugged flash memory directly without eject, USB error message shown on the screen,After that,although I've removed all of usb devices&cables on the connector,But USB error message always pop up periodically.I tried SMC reset, But issue still existed?

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.
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.

Seems my left USB port outputs more power than my right. Certain devices charge fine on the left but not on the right.

I just got my dual 2ghz G5 that I bought off ebay. I love it. Anyway, it has a 64mb Radeon 9600 Pro with the two monitor ports. I plugged my 22" Samsung into the DVI port. I want to buy another identical monitor for the other port, but it looks different. I found a graphic that shows the card's ports: [URL]. The top one in the graphic is where I put the connection. The bottom one is different. Is there an adapter or something? Or since I'm using two non-Apple monitors, should I just get a new card? BTW, I just bought and installed Leopard.

Ive got a 2008 Mac Pro and recently Ive been experiencing some issues with its USB ports. The front usb ports have a USB antenna connected and some time later, it just loses power and I have to disconnect it and connect it in order to make it work again. Besides that, Ive got a USB hub connected in one of the back ports. In it, is my camera and my keyboard. After some time, it just loses power. Not at the same time than the usb antenna, but in less that an hour I have to repeat the process 2-3 times. Worth to note, that in the two back usb ports left, Ive got an external hard drive in each and I dont have problems, there are always seen in the finder.
View 3 Replies View RelatedI have had an intermittent problem. Every so often (once a month), my iPhone will not connect to my computer, it does not charge, nor does it show up in iTunes. I checked out 3 different cables, and none work (cable problem eliminated), I tried 3 different iPods, none charged or showed up (iPhone and iPod problem eliminated). I tried both the front and the rear USB ports and nothing ever happens. As far as I recall, this problem just cures itself after a few days. Any idea what I need to have repaired to stop this maddening problem?

View 4 Replies View RelatedI have a tough one regarding an iMac G5 ALS 17" 2Mhz I am fixing. First I want to point out that I am familiar with the innards of these ancient beasts as I have fixed a couple 1st gen iMac G5 as well as iSights and Duos.
When I plug in the cord in the PSU, the 1st diagnostic LED comes on but when trying to start the computer the second diagnostic LED comes briefly on and then goes off. Nothing else happens, no chimes, nothing. According to Apple KB this is the sign of a faulty PSU. Yet, I have tried replacing the PSU and I get the same result.
Now the weird part is that if I unhook the LCD cable the computer starts normally (it chimes) with the display off. What is most puzzling is that it will start with the inverter hooked up but the LCD display cable off but will not start with the inverter entirely taken off but with the LCD cable on. It seems that it is the LCD itself that prevent the computer from starting. I thought the inverter would draw current but not the LCD itself so it's probably something else.
Anybody had anything similar happen to them? Could it be that the inverter is faly but it only draws when the LCD is hooked? Could it be some kind of short in the LCD or something that make it draw even with the inverter unhooked?

Are there any good chemical drawing software out there? I am a student who is currently studying chemistry courses in the university. For those who are familiar, I am looking for some good software which can draw nice chemical structures also to include some of the mechanisms.
