If my left USB port works, will a Left I/O Board replacement fix my issue?

I recently bought a Macbook Pro 2.33GHz off of craigslist. The seller made it seem like the issue was a dead battery because it would not take a charge. I have been looking online and it seems like the Left I/O board could be the issue. I have no problem buying one of these and replacing it myself, but I want to know if that could be the issue even though my left USB port and headphone jack works (part of the same board).

Hi acceler8,
before making a decision why not simply take the battery for testing at a local Apple AASP or store or try it in another MBP? If the battery proves to be the cause of the problem, then a new I/O board is not likely to do much good. If the battery is fine, then the I/O board would be one of the candidates as the cause of the problem. But a "battery that won't take a charge" usually results from either it being defective, OR from it having been allowed to discharge to a point where its own built in microprocessor is no longer able to operate (in the latter case they can sometimes be revived, if they have't been left too long).
But it is far easier/cheaper to get the battery tested first, than to go to the work and expense of replacing the i/o board and then find you you simply really needed a new battery anyway!
If the computer runs fine off the mains power supply it is unlikely to be the I/O. More likely to be the battery or the logicboard.
Cheers

Thinkpad W530: None of the USB ports work when used with a 4338-35U replicator

I have tried mouse. keyboard and a generic USB stick with a LED. None of the USB ports work on the replicator. Everything works fine when connected directly to the W530. The replicator ports must not have power because the LED doesn't come on.

Hi mmjmm123,
How long have you had your replicator?
Has it always been like this?

I did factory install on my hp probook 4520s and usb ports worked

did factory instasll usb ports worked after restarting it saids usb ports cannot start in deviice mangager

You should really read the manual.
"How do you restore from backup? "
Restore. When given the choice, choose to use backup.
"And how can I check to see if the pics and videos are on my computer somewhere first??"
They would only be where you put them. What program did you use to import them? Pics/vids taken with ipod are not part of the sync process at all. You should be importing them just as you would with any digital camera.
If you did not import them, then they are not on your computer.

Hi, is this a question" Post?
or are you just offering an insight into your Mouse Issue?
Generally and at times we all have little idiosyncrasies appearing with the running of our Macs.
I use the same Logitech BT with my MBP. MB & iBook..(not at the same time) Only ever had one issue
and the cure was to completely Delete the mouse from BT -> Repair Permissions & Reboot then Re Install the BT mouse..Ihave just put a new set of batteries in the Logitech (only 2nd set ever)...L

If you're really using iTunes 7.0 you are very far behind the current version - maybe it is trying to connect to a decomissioned server. In fact I am kind of surprised it will run on a Macbook Air. Are you sure you are running iTunes 7?

It is against TOU to speculate on these message board. Suggest you post your question on the Mac Rumors site.
As I already stated, there is no 10.6.8 update. If there was, it would be listed in Software Update.

Hey Etti101,
I'd start off your troubleshooting process by deleting and redownloading the songs:
If iTunes in the Cloud is available in your country, try the following steps to resolve the issue:
Delete the purchased song that is exhibiting the problem from your iTunes library.
Click on the Purchased link in the iTunes Store to view your previously purchased music.
Download your previously purchased song from this list.
via: Songs in iTunes may not play back completely

Left most usb port works with usb 3 devices but not with usb 2 devices

Can someone enlighten me on this issue? I have a MBP mid 12 that seems to have issues with usb 2 devices such iPods, HHDs, etc. The same port works fine with usb 3 devices. I have tried several solutions but not avail such as resetting the SMC, PROM, disconnecting the battery and reinstalling OS X from scratch. Is there anything Im missing? I still don't believe is a hardware issue but something wrong in the firmware...

Will external speakers on both 3.5 mm and a USB port work at the same time?

Have two sets of speakers that I want the same audio on. If I connect one set of speakers to 3.5 mm audio out, and the other set to a USB port, will I hear audio coming out of both sets?
If that's possible, do you know if I can regulate volume independently on both sets through Mac Mini?
Thanks in advance to any replies.

Thanks. So I guess my other option (if not getting into third party apps) is to split optical out or get a multi-zone receiver.
Thanks for the reply!

USB port 1 will not recognize a keyboard or a mouse

Hi,
I recently purchased a 2011 Mac Mini. Upon purchasing it, I was using a Logitech wireless keyboard and mouse combo with one of the mini receivers plugged into the first (far left) USB port on the back of the Mini. All worked fine, until I went to upgrade to an Apple wired keyboard.
I powered down the Mini, unplugged the Logitech receiver and plugged the Apple keyboard into the same port, and then powered back up. Upon reaching the Login screen, the keyboard was not responding to keystrokes at all, and no lights would come on for caps lock. I tried the second port, which happened to work just fine, as do the other two.
Now, no matter what I do, the system still thinks I have an unidentified keyboard attached and will not allow ANY other devices plugged into the first USB port to communicate with my Mini. Anything I plug into it only receives power through the port, no I/O can take place.
Is there something I'm overlooking here? Any help would be greatly appreciated. I have already tried plugging the Logitech receover back in, and lo and behold the Logitech keyboard and mouse will work on that port. I've tried taking the batteries out of the mouse and keyboard while the receiver is plugged in and the Mini is turned on. I've tried plugging in and then removing the receiver with the Mini on, and then using that port for the Apple keyboard... no luck.
Thanks in advance!
Chris

Did you turn Speakable Items Off?
System Preferences/Speech/Speech Recognition Turn if Off.
If that isn't the issue. Shut down your Mac. Disconnect your mouse and keyboard. Wait about 15 seconds. Reconnect the mouse and keyboard, then boot your Mac.
If that doesn't work, locate these files: com.apple.speech.prefs.plist and
com.apple.speech.recognition.prefs.plist
/Users/YourName/Library/Preferences. Drag those files from the Preferences folder to the Trash, empty the Trash and reboot.

No usb ports work, can't instal usb 3 driver

I received an HP Elitebook 8540w laptop from work, the hardrive was wiped with just the OS installed (windows 7 pro 64bit). I downloaded and installed all applicable drivers from here. Everything seems to work except the usb ports. There are three usb 2.0 ports on the left and two usb 3.0 ports on the right. None of them will recognize devices installed in them. My usb optical mouse's laser will flash for a second when it's plugged in and my external drive (1TB Passport) will spin up but never shows in nMy Computer as a accessible drive. Device Manager shows 2 Generic USB Hubs, 2 Standard Enhanced PCI to USB Host Controllers, and 2 USB Root Hubs. Comparing this to my other Elitebook 8540w it is missing a Renesa USB 3.0 Host Controller Hub. THis was one of the drivers installed with the others above but it's not showing anywhere. I've since removed and reinstalled this driver several times with no changes. Runing the USB 3.0 Host Controller Uitility that installs with this driver gives a "USB 3.0 Host Controller not found error." Please help!

Hi, Please check your IT deparment, they may disable USB ports elsewhere. My working laptops (all of them) have same "problem", my IT department even disabled C: drive, optical drive I can't see them anywhere. I can't see Devive Manager. I can only use USB ports to charge my phone or tablet. Regards.

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!

USB Ports work Intermittantly on Pavilion Notebook

I have a HP Pavilion dv7-2270us Entertainment Notebook PC that is running Windows 7. The USB ports seem to work intermittantly. There are two regular USB ports on the left hand side and one on the right. I have an iPhone, Adidas miCoach, and wireless mouse that I usually have plugged in, and lately nothing is recognized.
Sometimes I get an error that the USB device is not recognized, sometimes I get nothing at all as though the ports aren't even there.
I have tried taking out the battery, replacing and rebooting. I have also tried uninstalling the USB Root Hub, and then the Root Hub plus controllers. When I did this it seemed like it worked - I plugged my mouse in and it worked! I plugged my iPhone in and now nothing works again.
I have Norton 360 Installed (in case that is an issue), and I also have some old Sony Ericksson software that I've recently uninstalled because someone told me that it wreaked havoc on their machine in terms of their device drivers.
The laptop is just out of warranty (Dec 2010) so this is a relatively new machine. But I love all my gadgets and need to be able to use them all!

After re-installing OSX Lion neither USB Ports work

I have a Macbook Pro 15" Intel Core i7 Mid 2010 model, I had upgraded from the App Store to OSX Lion and was running ok, but at the time had half the disk partitioned into Windows, so got to the stage that I didn't want Windows so wiped it, and backed up the OSX Partition as I figured why not have a nice fresh OSX Lion install . . . . BIG MISTAKE
Since I've re-installed OSX Lion I now have no connectivity through the 2 USB Ports, or the SD Card as far as I can tell.
Since I'm a month out of the warranty I don't exist to Apple Support any more, so I've been trying everything I can think of or any suggestions I can find.
I've tried the PRAM and SMC resets which obviously don't work, I've tried the old 3+2 key trick - yup, you guessed it, NOTHING.
I have re-installed Lion 3 times, same deal - feck all is being recognised.
I've resorted to sticking a small Windows partition on at the moment to make sure it's not hardware issue, not sure what else I've tried?? Oh yeah, took it apart, removed the battery for an hour or so, even tried booting with no battery - nothing.
Any suggestions other than playing frisbee would be welcome, although, to be fair, I might end up having a game of that if this carries on ...

Ok, so been to the Genius Bar and basically they went through everything I had done already just to test it, and then also their own in-house hardware test that apparently only they can run, which is fair enough - all tests came back reporting the board in fine condition, and that the SD Card and USB Ports were fine, no errors.
So, we tested again after another PRAM/NVRAM and SMC Reset - still nothing - so he took it away and ran it on their other diagnostic machine which reset all the firmware and put it all back on again, testing at each stage and yet still nothing.
Basically I need a new Logic Board which will cost £400-£500 to replace, I know what you're thinking, and I am too, how brilliant is that!! .... Not very, but hey, what can I do?
Next stop, home insurance, I'm sure I pay you for some reason ... wish me luck!
Oh, I am going to try one more Lion install, just for the **** of it.

If my left USB port works, will a Left I/O Board replacement fix my issue?
