Problems when connecting and disconnecting MBP and TBD

Hello,
I have problems with connecting and disconnecting my macbook pro retina 13" to my thunderbolt display. Everytime I disconnect my MBP form my TBD with the lid closed it takes approximately 10 seconds until my MBP has recognized that the TBD is no longer connected and the MBP screens turns on.
On the other hand I also have a problem when I reconnect my MBP to my TBD. Approximately every second time my MBP does not recognize that the TBD is connected again and neither the MBP nor the TBD turns on. The small light on the power cabel of my TBD does not light up. It is as the TBD would'nt have any power. Pushing buttons on my Apple Bluethooth doesnt help. I have to disconnect and reconnect the thunderbolt and the power connector a coupl of times until the MBP finally recognizes the TBD and turns on. In some cases a different background picture is shown on the TBD than the one I usually have on my MBP.
The problem is very annoying especially because I connect and disconnect both devices and it really costs time.
I really hope there's someone who can help with the problem. Do you think this may be hardware problem of my MBP or TBD?
Thanks in advance for your help.

HI there,
The first thing I would recommend is checking for any new software updates while using the display, this will check for any available firmware updates for the display. If you continue to experience issues, then you may want to take a look at the article below for some further troubleshooting steps.

Mag Safe power cord sparks when connected or disconnected--whereupon the MacBook Pro 13'' dumps date and time, and all passwords, plus any/all unsaved information.

I purchased my MacBook Pro 13" from the Apple Store in Tucson, AZ, in mid-January. Since then, every time the Mag-Safe cord is jostled, not even disconnected, sparks fly from the power terminal on the computer, the computer shuts down, and dumps its passwords, as well as the date and time.
Any work in progress is also lost.
I work overseas, and Apple's advice was to give them my credit card number, await shipment of a new power supply and cord, and then, when I return the old power supply and cord, i'd receive a credit. That won't work, as packages from the US to my location take weeks if they arrive at all. There is no Apple Store within a reasonable distance. Or, Apple suggests, when I'm home on leave in mid-June, I should bring the computer to the Apple Store for repair--I have only days in which to do that, but I suppose I'll need to try. My concern is that I'll need to return overseas without my computer and won't be able to retrieve it for months, until my next leave.
This issue shows up elsewhere online. Is there a short in the power terminal in the computer, or on the Mag-Safe power cord, or within the computer itself? It's a known issue, thus I wonder why it hasn't been fixed.

Odd, but here's a copy of Page 1 of the links I got:

I bought a new MacBook Pro (Mac Os 10.8.4) when conecting my mobile broadband dongle (Huawei E122) the computer does not read it at all. I do not have problems when connecting it to my former computer (PC) and a Mac from last year. Any suggestions?

Thanks,
Yes, I did that. They have uppgrades for the dongles, but just untill Mac Os 10.7. Their solution is to buy a new modem from them or getting one for free if I sign a contract for 24 months! So, i think from that side not very helpful.
It is just that I do not want to buy a new modem, when it works in quite recent computers and after having spent money in the new Mac.
But thank you for your reply!

What have you tried so far in terms of troubleshooting this issue? Are you plugging the iPod into a high powered USB 2.0 port on the back of your PC? Have you tried a different USB cable?
What happens if you try to reset the device with it still connected to the PC?

Has this iPod ever worked on this PC or is this the first time you have time you have tried connecting it?

When i plug the USB for my iPad into my computer it will connect then disconnect over and over again untill i wiggle the usb around alot. This is happening to all my ports. But not on the other computer.

Hi. Whenever i plug my iPad (Happens with ipod and iphone too) to my computer usb for itunes is will connect, then disconnect over and over again. It has happened for a long time but doesnt happen on my other computer. how do i fix this?

If you have a spare cable, try using that. But the fact that this doesn't happen on your other computer (I assume using the same old cable) leads me to conclude that something else is at work. Maybe even the "bad" computer.

Oops - for some reason, this problem now seems to have gone away. May have had something to do with Flash. I'll keep my fingers crossed.

Please help me

I opened a new user on my computer yesterday with administrative privledges. I then opened up an itunes account from this new user. It seemed to go pretty well. I haven't downloaded any new songs yet or moved them to my account. I don't know how to move songs yet. I'm reading iPod and iTunes for Dummeies. Very appropriate for me. I will let you know when I manage to do this and am successful. Once again, thank you for your kindness and help. Kay 205

I am having problems when i have minimized windows and try to open a new window it will open all minimized windows along with the new window. It just changed when mozzilla updated. It did not do this before the update. Before the update if i had minimized windows they would stay minimized when i opened a new window. Please help ,I would guess it is just a setting somewhere but i cannot figure out where the setting is. Thanks jason

Try going to settings/general/reset/reset network settings and do that

Backup does not sync automatically when connected to wifi, locked and charging

i have bought 200G on iCloud to back my iPhone up to iCloud. after ensuring all my setting are correct.... my phone still does not automatically back up to iCloud when connected to wifi, locked and charging. it has been one month now and my iTunes still says that my iPhone has never been backed up, i am still receiving notifications on my phone saying that i have never backed up my phone, i have searched the net for any possible solution and it seems i have all my setting correct but still it doesn't work. any help would be appreciated thanks

Just to be clear, it will automatically backup to iCloud not iTunes.
Make sure you have iCloud Backup turned on:
Settings > iCloud > Backup > turn iCloud Backup on
If it is already on, it will tell you when it was last backed up under the Back Up Now button

My iPhone 5 got problem when connect with lighting cable, this will keep pop up message "this accessory may not be supported"

My iPhone 5 got problem when connect with lighting cable, this will keep pop up message "this accessory may not be supported", I can't charge or sync at all. I tried plug and unplug many time, still can't detect/charge my iPhone5, but sometime will 'lucky' that can connect to my iTunes and charge battery…
This message will auto pop up also when I don't have plug anything in my iPhone 5, It is very annoying…
The lighting cable is original and now i'm using OS 7.0.4 / iTunes is 11.1.3
What I can do to fix this problem? Thank you.

I would try using another cable you can likely borrow one to test from somebody
if it's the same then likely the connector in your iphone have been damaged

New Macbook Air i5 wireless is very slow and disconnect again and again. Any one has the same issue or some help??

I recently bought a new 13 inch Macbook air and wireless internet is really slow and disconnect again and again. However I hav another windows laptop at the same place and that never disconects or looses signals? wireless on this mac is too slow that I cannot even use to make a skype call. I am new mac user and getting a bit disappointed because of this bad performance.I googled about this issue and found that lot of people are having the same issue with macbook air. I switched off the bluetooth adaptor but still no progress. Any help will be appreciated. Thanks

I am experiencing something similar with my MBA 13"/i5/256GB.
To take it one step further, I started up a Terminal session and ran a ping against my wireless router. I see the same pattern repeated over and over: I get about 5 or 6 pings through, then 4 or 5 misses, then it reconnects again. When it reconnects, the first ping or two have times in thousands of milliseconds, where normal is maybe sub-millisecond to 4ms for the remaining few seconds.
I have other wireless devices, including iPhone, iPad, and an older MacBook - all work fine. The MBA is the only Lion device.

IPod Classic not recognized by iTunes, claims to be wiped of all content, and causes computer problems when connected

I have an 80 GB iPod Classic that has suddenly developed severe problems. I'm running iTunes on Windows 7 64 bit.
It was working fine until last night, when I connected it to iTunes to add 6 songs. (Four of these were bought on Amazon.com and 2 ripped from CD's). It accepted the songs and played them fine when connected. When I clicked the icon in iTunes to eject the iPod, it came up with the "OK to Disconnect" and progress bar as usual. However, this time the progress bar didn't start to fill in. It just sat there.
After several minutes the progress bar finally filled in and returned to the menu... but instead of displaying the cover flow on the right side as usual, it showed a gray box with "No Music."
When I tried to re-connect it to my computer, iTunes would not recognize it. My computer also wouldn't recognize it at first... after several minutes, it came up as a generic removable device. Attempting to right-click on it or eject it from Windows was unsuccessful.
The iPod itself displayed "Connected" and alternated the plug image with the spinning arrows. It never said "Synchronizing" as it usually does.
Furthermore, my computer's performance degraded severely while the iPod was plugged in. iTunes itself froze, and even my other applications (such as my web browser) would not work correctly. This all cleared up as soon as I unplugged the iPod. If I tried to initialize iTunes while the iPod was plugged in, it would not open. It opened immediately when I unplugged the iPod.
Finally, despite claiming to have no music or other contents (it had contained only my iTunes music library, which is about 26.5 GB), in Settings the iPod claimed to have only 5.3 GB of free space.
Resetting the iPod with Select/Menu made no change. I was able to put it in diagnostic mode and check the hard drive, which gave these results:
Retracts: 381
Reallocs: 0
Pending Sectors: 10
PowerOn Hours: 417
Smart/Stops: 381
Temp: Current 24c
Temp: Min 15c
Temp: Max 48c
When I put the iPod up to my ear I hear a steady, faint high-pitched sound and an occasional very faint crackling noise. When it shuts down the sound continues for a few seconds, then ends with a kind of squeaking sound.
The iPod is more than 5 years old, so I'm prepared for the probability that it's fried. But I'd like to try everything before I go ahead and spring for a new one.

The iPod's hard drive probably has data corruption. That does not necessarily mean there is a hardware problem. Hard drives, including the ones in computers, can develop data corruption.
Try putting the iPod into Disk Mode
http://support.apple.com/kb/ht1363
If it goes into Disk Mode, run iTunes on the computer and connect the iPod. To eliminate other potential issues, you should disconnect other USB devices (you can leave standard keyboard/mouse connected), and connect the iPod to a direct USB port on the computer.
iTunes may prompt you to do a Restore, which you should do. This will erase the iPod, re-install its software, and set it to default settings. If the problem was only data corruption, and there is no hardware problems, the iPod should have a "fresh start." You can sync it from your iTunes library.
If the iPod does not go into Disk Mode, or if doing a Restore fails, the iPod's hard drive may be faulty.
