IDEAPAD V460 - USB port disconnects randomly

Hi Community,
I am in a trouble with my IDEAPAD V460, 59 - 044185 (4th one from the beginning) which I purchased around a couple of years back. It was working fine without this annoying issue until recently. This partiular model comes with three USB ports, two on the left side, one on the right side.Since around last 15-20 days, any device plugged into any one of the two USB ports on the left hand side of the laptop is getting disconnected randomly. I use an iBall 4*1 USB hub to connect one keybaord, one mouse and one modem to any one of the USB ports on the left side. Initially I thought it to be a software issue. But reinstalling the OS or even switching over to other OS did not solve the issue. To probe more, I refrained from using the hub and connected two of the mentioned devices directly to the left side ports. Still, the problem persists, but the frequency of disconnection is less. Sometimes, the devices gets reconnected, sometimes do not. That is also in a random fashion.
One of my friend having a Y500 model also having similar issue. As you can understand, given the number of USB devices we use everyday, it's hampering my day-to-day activity.
Two years being passed, I am out of warranty. I found that there are so many people around here also having same or similar issues. Presently, my perception is that those to USB are not being able to pull out enough power to maintain +5V and causing this random disconnect. Any idea what to do?

Hi, clara_from_brazi.
Thank you for visiting Apple Support Communities.
Here are some troubleshooting steps that I would recommend when experiencing this issue. Also, test connecting the external storage device to the computer with another cable as this can be the issue.

Macbook Pro right USB port disconnects

Hi - When using the dialup modem adapter in the right USB port it will disconnect after 3-4 minutes but works fine in the left port. Flash drives & scanner seem to work OK in the right.
Also, a friend has computerized embroidery sewing machine and the right port does not recognized it but the left does on her MAC.
Are Macs were bought a couple weeks apart.
Is there a setting for each USB port that maybe wrong or is this just a defect?

Well, does that link...

still lock up your Mac? No way it should have any such effect.

Z87-G45 USB ports disconnecting / not recognized

I am having some frustrating issues with usb devices. The only USB device that seems to work is my mouse plugged into the back 3.0 port.
Computer is 2 weeks old and I originally loaded windows 8.1 pro from USB on a fresh install and it worked great and was working fine until a few days ago. I noticed the issue started when I turned the computer on from a power save and the bios got stuck on a black page with the code "9c". When usb devices were unplugged this went away. If i plug them back in they won't stay connected and if I restart "9c" error code returns.
At one point I was able to have my 2gb seagate USB drive + a 16GB flash drive + a logitech webcam plugged in and all worked beautifully.
Something changed - now if I plug anything into the front usb ports I just keep getting windows reconnect/disconnect dings. If i plug into the back USB ports I am getting "USB device not recognized" and other errors. Keyboard works fine as its plugged into p2p port and not USB.
My bios is up to date and also there are no exclamation marks in the device manager.
I have tried changing the power management settings,
uninstalling all USB devices in Device Manager
unplugging/re installing logitech g400 mouse and drivers
I reinstalled chipset drivers from MSI support page
Checking/replugging the front usb 3.0 connector on mobo
This is driving me insane.

Aha, that is the newer chipset for sure. That destroys my initial thought then.
Added: How are the Control Panel Power Options set up in the OS?

USB ports disconnect

When I plug in my digital camera computer either locks up or needs to be restarted to show up. Also, while I am working my printer and other accessories disconnect from the USB ports, or, in effect, can't see the computer. I have a four port PCI USB card in my mac. The camera is an Olympus 720.
I will post the manufacturer of the card when I get home. Has anyone else had problems with plug in USB cards and OSX (panther)
TIA,
Hib.
G4, OSX (Panther)

Yes I am having a problem with my USB port now after three or four years of not having any problems.
I've changed cables, brought a new hub, and my devices seem to only work correctly pluging into the port on the back of the computer.

Closed-lid mode USB devices disconnect randomly

I just recently connected my MacBook Pro to my Samsung DLP HDTV and started running it in closed-lid mode so my TV is the primary/only display. I also have an external hard drive (USB), external mouse (wireless with USB toggle) and the new Apple bluetooth keyboard.
The problem I have isn't entering the closed-lid mode. But once in closed-lid mode (after a short period of time) all of my USB devices disconnect and then reconnect. I know this because I get an error saying that my hard drive was removed improperly (please eject before disconnecting, etc) and I also get a message from my mouse software saying that my mouse has been disconnected. But then they reconnect themselves (hard drive shows up again on desktop and mouse software informs me that the mouse is present again).
Has anyone had this problem before where USB devices disconnect in the closed-lid mode? I just upgraded to Leopard (formatted the drive and started from scratch). I never tried this within Tiger so I don't have that for a reference. This is really annoying because I have my entire music collection on the external hard drive and it just stops playing when this happens and I have to restore the path to my music collection within iTunes' preferences (it defaults back to ~/Music/iTunes/ when it figures out that the hard drive is no longer there).
The strange thing about this is that when I don't run in closed-lid mode this never happens. I'll be more than happy to provide more details if needed. I greatly appreciate your help.
Thanks!
Mike

i appear to have the same problem under Vista (via Bootcamp) on MBP (2007). i close the lid, and 5-20min later i hear the sound a USB device makes when it disconnects, and a minute or 5 later it reconnects. i don't actually have any USB devices plugged in, but there are several components in the MBP that are connected internally via USB (DVD drive, etc).
what's almost as annoying is that the LCD backlight will come back on of its own accord, even though the MBP's been idle for more than the LCD/backlight time-out period. after the next idle timeout it turns off, only to turn back on againa while later. i see this under OSX & Vista.

USB mouse disconnects randomly, sometimes comes back

ive been having a reoccuring problem with my logitech mouse disconnecting and reconnecting. as of lately it just disconnects and wont come back untill i unplug and replug it in, then it will work for a few more days. whats intresting is say the mouse disconnects...i can unplug my ipod cable (not attached to ipod) and plug that back in, and the mouse will reconnect. the computer is in a recording studio, it has a firewire audio interface connected, the mouse and keyboard going to seperate usb slots, an ilok, and my ipod cable. its a macpro 3.1 running 10.6.8 any thoughts?

Time to take it back in for repairs.

2007 15 inch MacBook Pro With Bad Battery, Bad Logic Board, Unreliable USB Ports - Good News Story?

I'm posting this to put it out there just in case someone else has had similar experiences. My MBP is a 2007 with the Intel Core 2 Duo 2.15 GHz processor running 10.6.8. I've had it since 2009, and it has been a flawless machine for me until recently.
In the last two weeks, the mouse would no longer respond to touch - it felt mushy instead of clicking. The machine also was extremely sensitive to any touch on the top of the computer. Lastly, and most frustratingly, the USB ports would randomly stop working upon waking the computer up. I use it in clamshell mode a lot, with a mac keyboard and a kensington turbo mouse. Often, the mouse would not work upon waking the computer up. Rebooting was the only solution and I was doing a lot of rebooting. This is my everything computer - work and personal - so I wanted someone to look at it.
I took it into a local business that specializes in Mac repair since it was vintage. After a day, the tech called me and said that the battery was split and that my other issues were probably logic board problems, and the logic board would be hard to find and expensive to replace. He said I might be able to use it without the battery, but that obviously would be a pain. The tech felt such pity for me that he did not even charge me the diagnostic fee.
I tried using it without the battery and the machine was extremely jittery in its response, plus the mouse button would still not work. I put the bad, split battery back in, and it did respond better (though not the mouse). I have just enough knowledge to know that electronics can behave very strangely when their batteries are bad and this one was especially bad. Against the tech's advice, I spent $69 for an Anker replacement battery from Amazon. I put it in, and all of my problems have gone away - including the mouse which now clicks just like it did 5 years ago when I bought it. It might be total coincidence, and I'm certainly not saying to anyone that if you have similar issues with your older, but much beloved MBP, that this will do the trick, but I did want to get this out there because $69 for a new battery is a lot better than >$1200 for a new machine (if you do not currently have or want to spend the money).
I do a weekly time machine backup and I will be really sad when this computer finally gives up the ghost, but since I've gotten a lot of good information from these forums, I wanted to pass this information along in the hope that it might help someone in the community. The two Steves have my undying admiration and respect.

Usb ports going out

My usb ports keep randomly ejecting anything plugged into them. How do I replace/repair the usb ports in my Early 2008 MacBook Pro 15 inch? I have already gone to System Preferences and unchecked the option to sleep the hard disks when the unit goes to sleep.

As Dale says:
Permissions you can ignore on 10.5 and 10.6:
http://support.apple.com/kb/TS1448?viewlocale=en_US
Using 'should be -rw-r--r-- , they are lrw-r--r--' as an example, you will see the that the permissions are not changed, but the | indicates a different location. This is because an update to Leopard changed the location of a number of system components.

So it's like I want to continue watching a movie from external drive and then player crashes because my hard disk partitions got unmounted...
I'm wondering if it can happen because disk is underpowered (it's connected only to one USB port because I lost my original USB cable which had two USB plugs). Anyway it would be strange as problem occurs also when disk is 'idle' so then the power consumption is also lower I assume. I can only say this disk was working just fine when used as internal drive. Any ideas?

Your recommendation to check cable was just - a good recommendation I played a little bit with the B connector and disk immediately stopped working. OMG it was so simple ;p Thanks. I have to buy a new cable (I hope the case is all right).
EDIT:
Confirmed with portable mp3 player. Cable (B connector) is damaged.
I just won't delete this thread as it's a perfect example to show that basic stuff and simplest things should be always checked first !

Right USB Port stops working after disconnecting device since 10.9.2

Hi,
Since updating to 10.9.2 the right USB port on my MBA stops working after diconnecting a device (tested: external hard drive, USB flash drive, USB HSPA Modem). The only way to get the port recognizing the device on that port is to do a restart. If the device is connected from starting the MBA it works fine, if I then eject the drive and reinsert it or a different USB device the device doesn't get recognized. The devices do get power, my WD passport ultra spins up just fine, the USB HSPA modem also indicates it's working (with signal) but nothing shows up in finder or diskutility. If the modem is connected from start (and thus working) and then disconnect from the internet but not remove the drive I can reconnect to the internet. The problem only occurs after disconnecting the device. The port becomes inactive. The left USB port works as expected.
Steps I've taken:

Nothing out of the ordinairy. Thanks for any help

It's an Apple Pro keyboard and mouse, the dongle is
plugged into the Mac and not the keyboard. The same
set-up is, and has been working on all our other
Macs.
The sleep issue sounds interesting- hum, maybe...
Is your keyboard plugged into one of the USB connections on an Apple monitor? If so, you may want to change that connection to one that is on the G5 itself. My monitor came with a warning note indicating that problems will likely occur if the keyboard is connected to the monitor.
I also had a problem with the automatic sleep function. After much trouble-shooting and a logic board replacement, it was concluded that coming out of the automatic sleep function with any USB device active would freeze the entire USB bus. After disabling automatic sleep in system preferences, I've had no freezing problems. My machine works fine with the manual sleep function in the Apple Menu.

I have a 2013 Buick Enclave with Pandora icon on the screen. I was told that to connect my iphone 5 with USB port and that worked. But as soon as I disconnected, Pandora went out on screen. Only works plugged in now. Should work without USB connected.

I have a 2013 Buick Enclave with Pandora and Stitcher on the nav screen. With my Samsung S3, Pandora automatically lit up and worked. with new iphone5, I was told I need to connect USB port to car and phone and start Pandora. That worked and the icon on screen lit up. but as soon as I removed the USB cord, Pandora and Stitcher greyed out and stopped working. I know it's supposed to work on the car's nav screen once I hardwire it (at least that's what I was told), but as soon as I disconnect, they stop working through the car. How can I install Pandora and Stitcher on my car WITHOUT having the usb cord attached? the idea is to be able to use the car's touch screen to control Pandora, but with the phone plugged into the USB port, I can only use the phone to control Pandora, which of course is dangerous when driving! And it worked correctly with the samsung, so I have to believe it can work with the iphone 5! Right? Thanks.

You cannot install the apps on the car.
The cars head unit is merely acting as an interface to the apps on the device.
If you want to use those apps in the car, plug the device in and leave it plugged in.

When my iPhone is connected (via the Lightning cable) to the usb port in my car, the alert tones are no longer played through the car speaker or the phone. This previously worked, but has randomly stopped working, help!

I took my iPhone to the Service center of M/s RSG INFOTECH PRIVATE LIMITED on April 17, 2014.
Why are you posting in this forum about what occured with an independent service provider? How is is at all relevant to Apple?? In fact, service by any person or business not authorized by Apple voids any waranty.

USB Ports Randomly Stop Working

I have an HP Pavilion dv6 Notebook with Windows 7. All of the ports, 2 2.0 and 2 3.0 ports, began to randomly stop working. My mouse light would still light up, but the mouse wouldn't work. If I rebooted the entire laptop, all of the ports would come back on for a short period of time before they randomly shut off again. They will also come back on for a short period of time if I close the lid for a few seconds and reopen it. However, lately, the 3.0 ports have stopped working entirely and the 2.0 ports stopping is becoming more frequent.
The first time I noticed this was when I was testing a micro usb cable (it has stopped charging and I was testing whether it was the cable or the wall adapter). I plugged the cable into one of the 2.0 ports and it gave me a USB surge warning. Other than that, I haven't received any notices. The drivers are up to date. I have uninstalld the root hubs multiple times. I have tried all kinds of Power plans for the laptop. Nothing works. The USB ports still stop working, and it's becoming increasingly more frustrating.

Hello Abby_Renee,
With the USB 3.0 port not working, and your 2.0 port working intermittently, I would suggest the following document Troubleshooting USB Connections (Windows 7) for troubleshooting.
In this document there is a specific option for USB 3.0 ports stop working, which would be the best steps to follow for your 3.0 ports. Now for the 2.0 ports, I would suggest USB device not detected by Windows (no device name in device manager), or the other option is USB devices are detected by Windows but are not working properly. The last two options are dependant on the specific errors you are experiencing.
Please let me know the outcome of the troubleshooting steps.
Good Luck!

All USB ports seem to stop working "randomly" but some remain functioning until unplugged and plugged back in. [WINDOWS 8.1]

The devices that die right away are the network adapter and any USB memory stick plugged in, they still have their lights and all running but aren't recognized in "This PC" and the network adapter isn't found in "Control Panel\Network and
Internet\Network Connections".
My keyboard, wireless mouse that runs through the keyboard's USB ports and the external HDD remains functional UNTIL I pull the plug on them, after that plugging them back in does nothing.
I put randomly in quotations because it seems to fail more often when I download something at speeds over 3Mb/s, for an example downloading Hearthstone through the Battle.Net client will more often than not make the issue happen after a little bit. BUT it still
happens randomly during NO network load what-so-ever.

* [Downloaded these chipset drivers](http://support.amd.com/en-us/download/chipset?os=Windows%208.1%20-%2064)
* Installed all Windows 7 drivers I could find except the BIOS ones due to lack of Windows 8.1 drivers from http://www.asus.com/Motherboards/CROSSHAIR_IV_FORMULA/HelpDesk_Download/
* Turned off "Allow this computer to turn off this device to save power" in Device Manager for ALL devices in the USB tab that had the option, and the Network tab.
* Set the Power Options to high performance and disabled "USB Selective Suspended Setting"
I simply don't know what to do anymore and it's breaking me down, I need this fixed before the weekend or the LAN I'm planning to go to will be a disaster and I'll probably go insane trying to solve this myself.
Just tell me whatever more information you could need and I'll supply it, I'm desperate to get this solved.
**I never had any of these issues on my old PC that had different parts but the same network adapter and external HDD so they are not to blame for this, same for keyboard and mouse.**

Hey, I hope this helps you out a bit... I have had the same issue on my Asus K55A notebook with Win8.1 Pro x64 from the beginning! Thru my extensive research I found something interesting and the possible cause to all this! What I found was that by design
the xHCI Host Controller has virtual HS 2.0 Ports linked to the 3.0 Ports... Enabling compatibility with 2.0 devices ok... What happens is that the xHCI stack is unstable just like you say... The ONLY WAY I was able to fix the problem was by unlocking the
UEFI/BIOS to allow me full access to USB Configurations... I had to disable 2 of the HS ports under the xHCI Controller since I have only 2x 3.0 ports... This allowed 3.0 devices to be enumerated correctly under the xHCI stack and 2.0 devices now were enumerated
under the EHCI 2.0 stack... That's what worked in my case... I'm still digging around for more info about this issue because I find it so odd that no one discovered this when designing xHCI stacks and drivers at MS for Win8/8.1 x64... I hope I shed some light
on this issue... Good luck and keep us posted!
Hi, Sebastian. I have the same problem but i'm getting crazy trying to solve it. Can you help me to unlock the UEFI to access full USB config? and give me some suggestions on how to solve the problem?

Thanks in advance!
