Usb port on MacBook Pro stopped working

A usb port has stopped working. How to repair.

I would do another SMC reset. If nothing changes you should take the computer in to an Apple store for a free diagnostic. You should make an appointment.

I have pluged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?

I have plugged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?
if the device I connected have caused this, shouldn't the macbook itself have some type of protection that should prevent this from happening.
because when I took it to an apple certified maintenance shop, the guy said that now it could only run while connected to the power. it won't run on batteries. and that I have to change the motherboard.
can I just replace the damaged part only, would apple consider this as a design issue and they could pay for it, or should I just buy a new motherboard for 800$.
Help.

BB1B2,
The problem is in finding a tech shop that will/can do board level repairs on Macs. They are few. And I certainly wouldn't spend $800 on a new logic board - I would replace the computer if I had to pay that much!
You could call around to a few repair shops and see if they feel competent to isolate the problem and do a board level repair - but I'm afraid, in the end, that your search will be futile.
Sorry,
Clinton

Need help one USB Port on MacBook Pro not working

Its been a weak now and im getting tired of my MacBook pro USB not reading anything.. It wont read/connect usb drives, IPods/IPhones/IPads, and Android phones. I have tried the PRAM and SMC resets and nothing has worked i even left my Macbook pro off for a whole day. ITS ONLY ONE PORT NOT WORKING, i took it to bestbuy because its closest to me but geek squad just did what i explained above and told me get a USB hub and NO! i want to fix this issue... Anyone has had this happen can you let me know if its because the USB port is no longer working or a software issue... Also i keep getting this notification telling me USB devices disabled draining to much power but i have nothing connected!!
ps- my MacBook Pro is getting very hot fast and it happens when im not even using it, i get home and it very hot could there be another hardware failure i dont leave applications open when i sleep it.

It sounds like you might have a hardware problem. Your best bet is to go to the Genius Bar. The evaluation is free, and they'll fix it if you're under Applecare. Back up your stuff first though.

My USB port on my Macbook Pro stopped working and i tried the SMC reset and the one closest to the SD port still continues to not work. Is there anything i can do besides bringing it in?

USB ports in my macbook pro stop working

For a few months now the USB ports in my Macbook Pro stop working. The mouse is unable to move the pointer, therefore, I have to use the trackpad to select things. Then, when i try to shut it down it refuses to shut down, so I have to hold the on/off button to turn it off. When I turn on the laptop, the problem goes away. It's been happening more often for the last few weeks. Is there a problem with the software or is it the fact that I never used a base to raise the laptop, until recently, to let air in below so it doesnt heat up so much?
Any help is appreciated.

I still don't know what happened to my test Aperture Library after the update to 3.4...Not only were my previews lost, but so were the original images! Needless to say, I haven't bothered to update the main library on the Mac Pro because I don't want to deal with this level of uncertainty (even with backups in place).

My macbook pro stopped working

my macbook pro stopped working when i was out of town. i took it to an apple certified repairing store and they told me that as my waranty period was over 1 month back i have to pay 800-900$ to repair it. I would like to know if I buy an apple care now will it still cover the repairing cost?
I also need to know what are the different repairings are supported by apple care.

Hey AbdullahAbudiak
It would be hard to determine that at this point, but check out the articles below to get you going on isolating if it is hardware or software.

Why did my MacBook Pro stopped working

Hey,
Yesterday my MacBook Pro stopped working (got stuck on the opening screen with the spinning wheel)
I fixed it..but my question is what made it do this?
Thanks,

Oh - your profile shows 10.8 - which is Mountain Lion.
There's no telling what could cause a one-time event like that - could be any number of things - but if it happens again, call back.

One of the USB ports on MacBook Pro does not work.

Hi,
I purchased a MacBook Pro in Jan '11. Both the USB ports on the laptop were working fine. Recently, I have noticed, any external device connected to the USB port, towards the battery side does not recognize the connection.
Any solutions ?. Is this defect covered under warranty ?.
Regards
Anil Madan

Anil,
Try resetting the SMC.
SMC RESET
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Why MY ipad don't charge on usb port, on Macbook pro

why MY ipad don't charge on usb port, on Macbook pro

Because the port you're using just isn't putting out enough juice. The Power Adapter which came with your iPad puts out 2A of charging current, while the most powerful USB port on any computer is going to be putting out 500mA at most (and many brands, especially PC laptops, put out considierably less).
That's why your User's Guide recommends you use the Power Adapter.

USB Ports on Macbook Pro (Late 2011) no longer working...

Hey all,
I know there are numurous posts on this but none have seemed to help me.
Today both of my USB ports have stopped working. Two months ago the one next to the thunderbolt port would go in and out and today both of them just don't work at all except to supply power. I can still charge my phone with them but thats it, nothing is recognized when I plug it in.
I've tried the PRAM reset, the SMC reset, manual reset, regular reset, updating the OSX to the latest and nothing has helped. I've read I might have to replace the logic board but I really hope I don't have to resort to that.
I've posted the reports from the System Information and an app called Etrecheck. Hopefully someone will be able to pinpoint the issue.

Thanks for the response,
1. I live in Atlanta, close enough to an Apple store. But I just know that going there will probably mean I'll have to get the logic board replaced.
2. The only thing I noticed before the first USB port started acting funny was that my battery status changed to "Service Battery". I plan on replacing it this week too.
3. Nope only difference is that my battery drains kind of fast. After about 3-4 hours of my normal usuage with it (Internet, music, videos, and sometimes using Logic) it will be time to hook up the charger.
Would replacing the battery do anything? I'm not thinking it would but figure it'd be worth a shot since I've got to replace it anyway.
And to goofyziggy,
I too noticed that most people who had this problem had some version of OSX 10.8.x

Lexar USB plugged into Macbook Pro stops wireless connection from working

Just purchased a Macbook Pro recently. Noticed today that when a USB stick was plugged in (Lexar 32 GB USB 3.0) was plugged in, the wireless networking could not connect to any network services.
Finder kept trying to get to the network storage and failing or timing out. Time Machine failed to reach the server.
Unplugging the USB stick fixed the problem.
Anyone seen this before?
Chris

Thanks again for your help Rod!
One of the first things I tried was different combinations of devices to see if it may have been the device just not powering up. The main device I use is an official Apple wired keyboard, because at home I connect my MBP to my monitor and use a separate keyboard and mouse. I have tried other devices too with the same result, they only work when the dock is connected. I have tried connecting my iPhone via USB cable, i have a 16GB SanDisk Cruzer flash drive, which only lights up if the dock is connected, and I have a 4 port USB hub with a power LED on it, which again only lights up when the dock is connected.
I looked in system profiler, and it says the USB ports are there, but doesn't recognise any devices plugged in, other than the dock. However, when the dock is plugged in, for example, it recognises the Apple keyboard in the other port.
I took two screen shots, one of system profiler without the dock plugged in (USB keyboard still plugged in but not showing up), and another of when I plugged the dock in.
Without Dock:
With Dock:
It might be worth pointing out that the HDD dock has two USB ports on it, which is what is highlighted in the second pic.
I have also tried rebooting the computer with devices already attached but with the same result again. I've tried booting it with the dock and the keyboard attached, with just the keyboard, with just the dock, but either way unless the dock is connected, nothing else will work via USB.
I just want to say thanks again Rod, it's very kind of you to spend your time trying to help me, and it is really appreciated!
I'm going to contact Apple support shortly and see if they can offer a solution, or see if I can send it in for repair, which I am reluctant to do seeing as it's my only computer
Cheers!
