Monitor turns off when connected to USB or Firewire port

I just purchased a used Mac Mini Core 2 Duo and have a 20" Apple flay display with USB & Firewire ports. When I connect either of the USB or Firewire cables from the display to the Mac Mini, the display goes off. Is this some kind of short? Or is there some setting that causes this?

10 3.9 - external drive crashes PB when connected by USB or FireWire

Subject says most of it... "10 3.9 - external drive crashes PB when connected by USB or FireWire"
Details: I have one external drive which, when connected to my PowerBook via either FireWire or USB, causes the computer to lock up with the message: "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button." The same thing happens whether the drive is there on bootup or if it is connected later.
The drive worked fine until yesterday, when I stupidly installed Windows Media Player even though the internal drive was almost full. It took a while, but I discovered that disconnecting this particular external drive made everything work again, though slowly.
Then I freed up 15GB on the internal drive, and everything works normally _unless that drive is attached. Another drive connected the same way works fine.
I have searched around on this message but have yet to find the way out. I did figure out what the first question will probably be, so here's the answer:
The "kernel panic message" each time seems to be the date and time and then "localhost /usr/libexec/panicdump: Error (-1) setting variable - 'aapl,panic-info'"
Where should I start?
Thanks.
15" Powerbook Mac OS X (10.3.9) External drives connected via USB or FireWire

Still hoping for some sort of advice here... Have tried many approaches but can only confirm that simply connecting that particular drive (or enclosure?) always gets an immediate shutdown.
Thanks for anything,
Steve

Wifi turns off when connected to mobile card, but wont turn back on

I have a Sprint wireless internet card. When I connect to the mobile card, the Wifi radio turns off. I'm fine with it turning off while I'm connected to the mobile card, but the problem is that it wont turn back on when I disconnect the mobile card. If I try to use the button or other basic on/off switches in windows to turn it on, they wont respond. The only way I can get it back on is to run a troubleshoot, which shows that the radio is disabled and asks if I want to apply the fix that will turn it back on.
I'm on a Toshiba Satellite A665-S5170, Windows 7 (64), in the U.S.
Thank you.

Hi
So does this also happen if you dont connect the notebook to external monitor? So you can determine what is causing this problem.
If the notebook doesnt shut down without external monitor you should try to update the BIOS and display driver. Both updates you can find on the Toshiba website:
http://eu.computers.toshiba-europe.com => Support & Downloads => Download Drivers
Do you close the lid if you have connected the external monitor?
What OS are you using?
Furthermore it would be interesting to know how you cleaned the notebook. Therefore I use compressed air spray that can blow out the dust from the cooling ventilators and you must not disassemble the notebook.
Bye

Monitor turns off when power is disconnected

Hi,
I have just recently purchased a new 15" Intel Macbook Pro.
I seem to be having problems with having an LCD monitor connected to it, and then pulling the power to the macbook.
The LCD monitor (Dell 22") turns off and I have to reboot the mac for it to come back onto the Dell.
Is this a known issue ? or is there a battery saving setting that turns off the DVI port or something ?
Any ideas would be appreciated.
Thanks in advance.
Phill

Thanks for the reply David.
It could be, we do have a few of them here, all of which are using the same dells, and I think they all have the same issue.
When running on power initially, it works fine, then if power is pulled, 22" LCD goes blank (power saving mode) - and you can then only use the Macbook screen.
However, when you lift the macbook lid and the desktop appears - the 22" Dell resumes - but as a secondary screen.
Very odd...

MBP crashes (turns off) when connected to projector

When i connect my mbp to my sharp projector using the included adapter the computer just turns off unexpectedly after about 8 seconds or so. Any ideas whats causing this?
macbook pro Mac OS X (10.4.6)

I am having a similar problem, when I connect my MacBook Pro to an external projector through the DVI-to-VGA adapter. It will eventually kernel panic and I have to reboot. After rebooting, it will eventually kernel panic again, usually within a few minutes.
This never happened in the same setup with my PowerBook G4.
I hope this is fixed quick, I teach with slides and this makes my new computer unusable.

I have just bought Macbookpro and when ı connect digital camera from firewire port ı never see the image at macbook pro.

I have just bought the macbook pro. When i connect the digital camera (sony dxc-c33p) to mac from firewire port i never see this camera imovie or quick time programs. Macbook pro never connect the digital cameras via firewire port. What can i do to solve this problem?

We are sony dealer for profesional medical products and i want to connect sony dxc-c33 digital camera to mac via firewire port. it is very interesting;
1. i have new imac at the office with latest software. when i have connected the camera it worked perfect no problem.
2. i have bought new macbook pro last week. when i connected the camera it didn't work.
3. i have connected the camera to imac mini with latest software. it worked perfect no problem.
4. finally i went to apple support office and we connected the camera and tried to take movie at four different brand new macbook pro but they didn't work.
Also when we lived this problem we have already contacted with sony support and no problem from this side. Iam still thinking the problem is firewire port at macbook pro. Finally we contacted exclusive dealer of apple in my country but they didn't solve and understand the problem yet until today (it passed 15 days)

Why doesn't Wi-Fi turn OFF when USB Ethernet is connected?

When I get into the office, I connect my MacBook Air (2011/Lion) via USB Ethernet (we have Wi-Fi too).
When connected through USB Ethernet, my Wi-Fi stays connected as well.
Is it possible to have Wi-Fi turn off automatically when connected via USB Ethernet?

You can configure your Network System Preferences so that your Ethernet interface has preference over wifi. It will not automatically turn off wifi, but it will use the Ethernet if it's plugged in.

MBP display turns off when external monitor is attached

Hi there,
Over the last few days I have been trying to get Windows 7 to work with an external monitor. I am running a Mid 2012 15" Macbook Pro with a Nvidia GeForce GT 650M GPU. I sucessfully installed windows 7 in bootcamp and everything worked flawlessly until I try to connect my monitor with the mini displayport via a VGA <-> Displayport adaptor. When I connect it the monitor powers on, with the windows desktop and is responsive but the mouse dissapears and the MacBook Pro's monitor turns off. The mouse is still useable but invisible, so its very difficult to do anything. I have tried to update the Nvidia drivers as well as trying everything I can think of and haven't been able to find a solution. Has anyone else out there exerinced this, or found a solution?

Okay, so a little update. I have determined that the problem is the nvidia driver. When I roll back the driver to the "Microsoft Basic Display Adaptor" driver and connect the monitor then it behaves as excpected. The external monitor isn't detected and everything continues to work properly.
So is there anyone out there who is running a Mid 2012 15" MacBook Pro with an external monitor in either Windows 7 or 8.1? If so please let me know what your setup is and what driver version you are using. This is driving me crazy. Thanks.

IPod Nano (4th Generation) switches on when connected to USB power - shows Menu & hangs (unresponsive to click wheel) - deems off after 5-sec - Switches off after disconnecting from USB Power - syncs with iTunes - Tried 5R's - Problem still persists

1. The iPod Nano (4th Generation - 8GB) switches on, only when connected to USB power by showing apple logo and displays Menu options thereafter..
2. However, I can not access Menu as it is unresponsive to click wheel. As a result it is inaccessible to any further use,
3. NOTE: it displays "Battery Fully charged" icon on the screen without any "Lock" icon.
4. After 5-sec to 10-secs the screen deems off.. i.e. goes to sleep mode.. And thereafter would probably remain like that (sleeeping) for eternity!!!!
5. It Switches off after WITHOUT DISPLAYING any Apple Logo immediately after disconnecting from USB Power.
6. In other words, it can be switched on only through USB power in spite of battery being fully charged.
7. Interestingly, it syncs with iTunes. It is recognised in iTunes (Latest version 11+).. Displays on screen all commands Like.. syncronising, connecting, connected,
8. Allows to add Music, videos like a normal ipod & displays all status information in iTunes.
9. Read Trobleshooting & Tried all 5R's. Registered, Resetted, updated & Restored to iOS 1.0.2
10. It is now displaying to select Language in place of Menu options, with no access through click wheel, centre button whatsoever... Problem still persists
KINDLY GUIDE ME THE SOLUTION. APPRECIATE YOUR RESPONSE in advance...

"I get the feeling that this is a software issue that could probably be solved quite easily"
Since you have already tried all the normal troubleshooting solutions, take the iPod to your nearest Apple Store for a *proper diagnosis.* The staff there will be able to confirm if your problem is software or hardware _*at no cost to you.*_

My ipod 4 fell and turned off, when i connect it appears recovery mode.

My ipod touch 4th gen froze! blank white screen and doesn't respond when turned off, or connected to my laptop

my ipod touch 4th gen froze! only blank white screen and doesn't respond when turned off or connected to my laptop!

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

I've run diagnostics. Can't find device. I've tried resetting. The toggle has been turned on and off.

Cable works fine on my other iPod. Reset by pressing menu and center button together for 6-10 seconds. Left it to charge for many hours. Started acting up while running. Suddenly the music stopped playing but my Nike + was still working for the rest of my run. Took it straight it home and plugged it in to the wall to recharge since the battery was fairly low. Looked like it recharged ok but then screen went blank and now does it not show up on iTunes, does not seem to recharge by the wall charger (apple wall charger plugged into a surge protector in India). I have turned the hold switch off and on many times.
Sounds like a repair issue, which is not easy to do in India :(

I'm sure your'e going to tell me I just need a new phone but maybe there is hope for my iphone 4. It will not charge past 66% (it's not the charger), it turns off when unplugged, and it will not even let me turn my wi fi to the on possition. Help!

Hi there 8472kck!
I have some information for you that can help you troubleshoot this issue a little further. That information can be found right here:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 15 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
and that information comes from this article:
