USB, Firewire Suddenly Shut off/Deactivated

Hello,
I recently tried to attach a La Cie hardddrive to the back of my cinema display and a message came up:
+*A usb device is currently drawing too much power.*+
+*The hub it is attached to will be deactivated."*+
There is no hub but now none of my harddrives will mount onto the desktop. I have no idea or experience with this and I can't work now. Please help quickly.
My display is attached to a G5 Tower.
Al

Hi! You should only attach hard drives directly to the motherboard or a powered hub other than a monitor. The over current has tripped the ports. It needs a pmu/smu reset. On the early G5's there is a button on the motherboard that has to be pressed once with all external cables unhooked and on the later ones unplug everything and let it sit for 30 minutes. Tom

What you should do next depends on the circumstances. For example:
If you installed the keylogger yourself and then forgot about it, remove it according to the developer's instructions. If you want to keep it, check for an update or refer to the developer for support.
If you're under 18 years old, and the keylogger was installed by a parent or guardian, talk it over within the family.
If you're an adult, and the keylogger was installed on your personal computer without your permission, then the computer may be evidence of a crime or a civil wrong. Consider the legal implications before you do anything. Assume that everything you've done with the computer is known to the party who installed the keylogger.
If the computer was issued to you by a school or employer, then you should check with the IT staff that the keylogger is authorized. Don't use the machine for personal business. If the keylogger interferes with your work, the IT staff will have to solve the problem.
In the event that the computer was tampered with by an unknown party, and you just want to clean it up, see below.
The only way you can be sure that the computer is not compromised is to erase at least the startup volume and restore it to something like the status quo ante. The easiest approach is to recover the entire system from a backup that predates the attack. Obviously, that's only practical if you know when the attack took place, and it was recent, and you have such a backup. You will lose all changes to data, such as email, that were made after the time of the snapshot. Some of those changes can be restored from a later backup.
If you don't know when the attack happened, or if it was too long ago for a complete rollback to be feasible, then you should erase and install OS X. If you don't already have at least two complete, independent backups of all data, then you must make them first. One backup is not enough to be safe.
When you restart after the installation, you'll be prompted to go through the initial setup process for a new computer. That’s when you transfer the data from a backup in Setup Assistant.
Select only users in the Setup Assistant dialog—not Applications, Other files and folders, or Computer & Network Settings. Don't transfer the Guest account, if it was enabled.
Reinstall third-party software from original media or fresh downloads—not from a backup, which may be contaminated.
Unless you were the target of an improbably sophisticated attack, this procedure will leave you with a clean system. If you have reason to think that you were the target of a sophisticated attack, then you need expert help.
That being done, change all Internet passwords and check all financial accounts for unauthorized transactions. Do this after the system has been secured, not before.

My ipad 2 suddenly shut off and asked me to connect to itunes it asks me to restore but it wont work need help pls

my ipad 2 suddenly shut off and asked me to connect to itunes it asks me to restore but it wont work need help pls

The iPad is telling you it has entered the recovery mode - you need to follow the instructions in http://support.apple.com/kb/HT1212 for connecting to a computer running iTunes by way of the recovery mode.

HP Pavilion P6-2220t. All security USB connections are shut off in BIOS. Need to turn on.

I was told that all of the Security USB connections was shut off in the BIOS. The only controls for this PC is USB ports for the mouse and keyboard control ect. How can I get into the bios without the keyboard and mouse in operation? There is no other way to control this model computer. The only connections on this PC is USB connections only. Again If I can, somehow get get into the BIOS I can turn the Security USB connections on as they should be.

Hi Big_Dave,Yes the ALL security USBs in the Bios are in fact shut off. I saw it done in front of me.The person was trying to install Windows 7 but the usbs in the bios stopped workingeach time he tried the install the software. He thought that shutting off the securityUSB in bios would stop the security only and allow windows to be installed. He thensaw that all the security USBs in bios had completely shut down the usb connectionscompletely. I didn't know that is what he actually done until he went through with meand told me everything that he had done step for step with me. Then it dawned onme that was in fact what I saw him do. Anyway the Security USBs are all shut off.Money is hard to come by here so it will remain disabled until someone can walk methrough getting it turned on somehow without working usb connections. I refurb.laptops but not PC desktops like this one. This is new to me also. I think I will stick torebuilding laptops after we figure out how to get into the back door or find a way tohelp[ him fix this problem if I can. Anyway thank you for your input into this problem.

Keyboard lights suddenly shut off

I'm a noob with an early 2011 MBP 13" i7 running Lion and I've noticed that the keyboard backlight has started to suddenly shut off randomly.
It's only happened a couple times and the last time it did I actually could turn it back on by pressing the correct button, but the time before that I had to restart the thing.
Am I crazy or is my mac posessed?

Hello Dave the Revelator!
Have you checked in the System Preferences > Keyboard > Keyboard "automatically illuminate keyboard in low light"? If yes, it is normal. When the light sensor is receiving bright light, the keyboard lightening is switched off.

After I upgrade maverick my display will suddenly shut off but my sounds is still working. Need help

After I upgrade maverick my display will suddenly shut off but my sounds is still working. Need help on this? Thank you

Hello rodamitjr,
It sounds like your iMac display will turn off unexpectedly, but you can tell the computer is still on because you hear audio.
I found an article with steps to troubleshoot issues with displays. This article is for internal and external displays, so you can skip any steps referring to an external display. I recommend reviewing the full article, but this step specifically stands out to me for the issue you described:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the full article here:

Suddenly shuts off, turns on (completely reboots)

Hi,
I have a Macbook Pro (15-inch, early 2011). My computer suddenly shuts off (fully charged, plugged in, no warnings of low battery or anything). When I turn it back on, it reboots completely (as opposed to restoring my session like it usually does if the battery dies) and says the battery is at 0%. This has happened a few times now. Does anybody know what it is or how to fix it? Thanks in advance!

Why is my Macbook suddenly shutting off?

I have a Macbook (A1278) and in the last couple of days it has started suddenly shutting off without warning.
The screen goes black and I have to press the power button to turn it back on.
This has happened both when the battery is full and when the power cord is attached.
There are no other problems that I have encountered in performance or otherwise.
The fully charged battery lasts 2 hours which is pretty good considering the computer is 5 years old.
Could this be a sign that I need to replace the battery? Or is something else the matter?
Solutions, advice or comments are greatly appreciated.

Run the hardware test that came with the machine. Boot off the 'D' key. If nothing happens, you need the original installer discs to run it.

Speaker working intermittently (keypad tones, ringer, etc...). There seems to be no rhyme or reason or common denominator to when or why it suddenly shuts off. Any advice?

The volume on my iPhone is working intermittently (keypad tones, ringer, etc...). There seems to be no rhyme or reason or common denominator to when or why it suddenly shuts off. Any advice?

The problem is pin corrosion on pin number 21. It is ver simple to clean out. Google "where is pin 21 on apple dock connector." Then get a pin or dull needle and gently pull it over pin number 21. You won't see the corrosion on the pin or even see it come off, but it works.

G460 Suddenly Shut OFF when forwarding video or doing some tasks

Hy, I have problem with my Lenovo G460.
When I played video, any kind of video, it's just running normal.
But, when I forward it just a little bit, it shut off without warning or anything.
I've tried to open the bottom cover and try running it.
The VGA fan seems OK to me, it run like usual.
I Don't know what happen.
My only clue is that, the charger has 4 kind of sound.
1. When plug in to the electricity,
2. When plug in to the electricity and plugged into the Laptop,
3, When plug in to the electricity and plugged into the Laptop when the laptop is ON,
4. The sound that coming after it suddenly shut OFF.
Is it the charger, or the laptop charge core???

hi,
can you check if there's any mini dump file in folder c:/windows/minidump. if there's any, please, copy it to desktop, upload it somewhere (rapidshare.com) and post the link back.

IMac suddenly shut off.

I was using my iMac earlier today when it suddenly shut off. The only programs I had opened were Safari and iTunes. I put my hands on top of the computer and noticed that it felt especially hot. Could the cause of my iMac shutting off be because it got too hot? Should I be concerned about possible damages that may have occurred? I appreciate your help.
One more thing; my iMac won't go to sleep according to the inactive time that I have specified in the Energy Saver settings. It only goes to sleep when I access the sleep command or push the power button. Otherwise it just stays on. Thanks again.

Thanks for all your replies, guys. I hadn't logged in since Monday so I didn't know that there had been more posts since then. Anyways, to address why there hasn't been a recall or any public recognition of the problem (that I know of), I have a theory: after all the Apple commercials that basically boil down to "Macs are better than PCs because Macs work," how bad would it look that they would have to do a major recall on these new iMacs?
This is actually my first Mac. I was really stoked about it because everyone that I spoke to that had owned Macs never had any complaints. I'm getting a little concerned now. We've spent good money on these machines and apparently for a lot of us they are turning out to be a major headache. If I wanted a computer that performed poorly I would have bought a PC and spent half the money (sorry to all the PC guys out there. I've had some bad experiences with PCs that helped fuel my decision to purchase a Mac).
Anyways, I've had another unexpected shutdown earlier today so I'm going to call Apple again and see what they say. For any of you who are having this problem and are going to call Apple for the first time, your support may go something like this: turn the computer off and turn it on again holding the Command, Option, P and R buttons simultaneously. Then, using the Disk Utility, you will verify the disk. Mine claimed that everything "seemed" to be okay and as of Monday I was to monitor my system and call back if it happened again. I'm going to call them again and I'll let you all know what they say.
Dennis, thanks for the link. I have not read it yet, but I will. I'll keep you all updated. Thanks again and good luck to all of you as you try to get your Mac issues resolved.

My Satellite L500 suddenly shuts off

Hi all!
I need help!!! my computer suddenly shuts off and I have no idea why!!!
TOSHIBA L500-22R

Beside the tests mentioned by Macius I guess the notebook shuts OFF due to high internal temperature.
Some background info: the notebook supports some kind of overheating protection. In case the temperature increase to a higher level, this protection prevents the hardware from damage.
I dont know how old your notebook is but I guess you never cleaned the cooling ventilators.
This should be done from time to time because the dust could affect the cooling performance.
Clean the fans and cooling grilles using a compressed air spray. Such air sprays can be ordered online or purchased from common computer dealers.
