IMac Thunderbolt ports stopped working

I have a late 2012 iMac 27". Both Thunderbolt ports no longer work.
Have tried an external monitor and hard drive. Nothing happens. Both work on another iMac.
Reset PRAM (left cmd+option+p+r), but nothing changed.

Thunderbolt to Gigabit Ethernet Adapter or Thunderbolt port stopped working

Hey problem if anyone can help:
I use a Thunderbolt to Gigabit Ethernet Adapter, and all of a sudden it stopped working to connect to the internet on my Macbook Air (MacBook Air (11-inch, Early 2014 with OS X Yosemite 10.10.1 (14B25)). In my system information it says it is connected even when not, see below:
Thunderbolt to Gigabit Ethernet Adapter:
Vendor Name: Apple Inc.
Device Name: Thunderbolt to Gigabit Ethernet Adapter
Vendor ID: 0x1
Device ID: 0x8003
Device Revision: 0x1
UID: 0x0001000202DD0A30
Apple Serial Number: DTN4263048VDWKHBQ
Route String: 1
Firmware Version: 5.5
Port (Upstream):
Status: Device connected
Link Status: 0x2
Speed: Up to 10 Gb/s x1
Port Micro Firmware Version: 0.0.8
Can anyone help me figure out what the issue is? Is it the Adapter, the Thunderbolt port itself? A gremlin? Thanks!

Which model MacBook Pro do you have? Does it have a Thunderbolt port? If so the TB->Ethernet adapter MAY work (although it's specifically designed for those MacBook models that lack an Ethernet port).
The adapter would certainly be the cheapest way to go - if it works. Personally, I would rather have the Ethernet port on my MacBook Pro working, but this may be an expensive fix, I don't know. If I were you, I would at least take your computer to your local Apple Store/AASP and get a free diagnosis and estimate to repair your MBP. If it seems as if it's going to be too costly, then you may certainly try the adapter and see if it works.

Mac mini thunderbolt port stop working

Good night.
First, I apologize for my English.
I have a mac mini (2011 model). Two days ago there was a power outage and the mac shut down. After turning it on, it failed to recognize my TV connected through the Thunderbolt port (with a adapter THUNDERBOLT -> HDMI).
When I disconnect and connect the adapter into the thunderbolt output, the screen flashes (as if he had recognized the second monitor). However, the monitor does not work.
Some Details:
1) In the monitor settings, only the main, connected by HDMI is detected;
2) On the "System Information" screen, the "Thunderbolt" item appears to state “no device connected";
3) I've done the reset PRAM / SMC.
Can anyone help me? Does my thunderbolt output fried?
Thank you,
Mateus.

I would try a different HDMI cable and then a different Thunderbolt/MiniDisplay Port to HDMI adapter.

Imac usb ports stopped working?

Hi, is his what you tried...
reset FW bus, same goes for USB reset...
Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive or devices.
3. leave it for 10 minutes.
4. Connect back up and reboot.

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. WHen we plugged it into the port on the keyboard, the device works. Why?

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. When we plugged it into the port on the keyboard, the device works. Why? Obviously the device is operational. Could the USB port have burned out from having too much power drawn? If so, is it reparable?

It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired.

MDB and Database - Listener port stops working

Hi,
I have created an MDB which does the following when a message is received from the queue.
1. Store message in database
2. do some processing
At step 1, if there is any issue with the database connection (e.g. database is not available etc), I rollback transaction. My idea is to leave the message on queue for now and retry it again after some time unless the database is back again. "Maximum retries" of the listener port is set to N but since there is no retry interval available, all N retries are done in a flash and my listener port stops working. I cannot use backout mechanism as I have to wait for the database to be back again. What are my options?

a simple JDBC rollback won't do it.
which app server are you using?

HP Pavilion dv6 All 4 USB ports stopped working

Hello,
I recently bought a Pavilion dv6-6c11sa laptop. Windows 7 Home Premium 64-bit
Everything was working fine for about a week, and then yesterday all of the USB ports stopped working. I have 4 USB ports in total, two 2.0 and two 3.0. No matter what peripheral device I plug in, mouse or flash drive etc, they're not recognized by the laptop. The lights don't even light up on the devices, regardless of the port. I've tried uninstalling and reinstalling the drivers in device manager, taking out the battery and rebooting, installing the chipset drivers (AMD), nothing works. No programs had been installed 3 days prior to the occurence, although I had rebooted several times in that time frame. I simply booted up the laptop yesterday, and nothing worked.
Could anyone offer a solution or suggestion, please?

Ports stopped working.

I used to use port 8001 for a lot of things. Recently, the port stopped working. I triple checked all my router settings and port 8001 is still forwarded. I tried other ports. I rebooted. I tried shutting off my firewall. Nothing worked. I really need a port working for various things so I need some help. Tell me if you need any additional information and I'll tell you. Does anyone know what I should do??

Well, I did everything you said and I'm sure I did it right. No luck. I have a feeling that something else is going on here, but I'm not sure what I should do. Anyone have any ideas?

HT2452 my imac keyboard has stopped working? help!!!

my imac keyboard has stopped working??? help!!!!!

My keyboard just stopped working out of the clear. One minuet OK next it was dead. No little green light at all. New batteries did not help.
FIXED THE PROBLEM! I took a small piece of aluminum, made a little ball out of it and dropped it down the tube where the batteries go. Replaced the batteries I had just used......little green light comes on and the the keyboard functions like always.
My guess is after a few years the contacts oxidize a bit and don't make contact with the batteries on the bottom of the tube. Give it a try.

1 of 2 USB ports stopped working after 10.7.2 upgrade

I have the newest Macbook Pro. I upgraded to 10.7.2 today and immediately after, 1 of my 2 usb ports stopped working.   Thought it may be the cable, so I switched cables. Tried plugging in my iPhone, my portable drive and nothing.   Both work on the other port though.   Both ports worked fine before the update.
I've rebooted 4x.
Suggestions?

    Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
If this does not help, contact Apple.

One usb port stopped working today

One of my USB ports stopped working today. I think it may be related to Itunes update today. Has anyone else seen this recently? I restarted my computer - but that didn't help. I have a MacBook Pro - running Lion 10.7.5
Any suggestions? I saw one USB Hub when I went to Apple --> About this Mac, but couldn't tell if both were there.

USB ports stopped working in my Macbook Pro

I do not know anything about audio consoles nor do I have an iPhone.
My iPod also does not show on the desktop but it is recognized in iTunes, Check if that is the case for your MBP.
Do you have the appropriate boxes checked in Finder Preferences?
See if this support article is of any assistance:

If you have an external HDD, connect it to your MBP and see if it is recognized. If it does not show on the desktop, check Disk Utility.
Have you tried all USB ports? It could be that the problem lies in your MBP.
Ciao.
