Re: Computer shuts down by itself, ethernet port stopped working (MS-7673 P67A-C45)

do a properties on each device with yellow mark and check its Hardware IDs

if the load temps are OK, try with a different PSU [quality one]
QuoteWindows tells me that Ethernet adapter is OK, but that no cable are connected. (It is!).
ethernet port stopped working
this suggest that board can be failing

  • Ethernet port stops working on location change

    I seem to have a problem with my ethernet port not working after a specific location change...
    I have three locations I used frequently. Let's call them:
    1) HomeWireless
    2) WorkWireless (used when I'm in meetings)
    3) WorkEthernet (used when I'm at my desk)
    My general practice is to change locations just before putting my MacBook Pro to sleep, and then it is happily ready for the desired network when it is awoken.
    I'm not sure what this change in behavior coincided with, but as of ~1 month ago, I am finding that going from WorkWireless to WorkEthernet, my ethernet port appears to be completely dead and I have to reboot the computer to reactivate it (yes, I've checked the cable itself and the wall port at they're OK). I've tried a couple ways of disabling & re-enabling it in software, but I don't get the impression anything actually resets this interface - suggestions are welcome as perhaps I just didn't try the right thing. I couldn't find anything quite the same as "networksetup -setairportpower" for the ethernet port.
    Oddly, this is not an issue with going from HomeWireless to WorkEthernet. Both HomeWirelss and WorkWireless have the ethernet interface deactivated in the Network pref pane, and perhaps the only notable difference between HomeWirelss and WorkWireless is that I use a static IP on the former and dynamic on the latter.
    Does anyone have an idea why this could be happening, or have any suggestions for something to check (e.g. some difference to look for between HomeWireless and WorkWireless that might hint at the issue), or at the very least a means of resstarting the ethernet port without rebooting.
    Thanks for any help,
    -Gene

    I'm still experiencing this issue. Anyone else? Any help on either understanding/fixing the underlying issue, or with resetting the Ethernet port to deal with it?

  • Use of ethernet port stopped working

    I use my Airport Express to connect to my existing wireless network (an Airport Extreme Base Station).
    For over a year I've been using the ethernet port on the express to connect to my Playstation 2 so I can play video games over the internet and it's worked great.
    Mysteriously, it recently stopped working. When I go into base station options (in the Airport Admin) it says "ethernet port always disabled when connected to existing wireless network."
    I don't know if it said that before when it used to work, but I'm wondering if something changed.
    I recently read through the forum and saw all the problems with the recent firmware upgrade and I seem to have successfully downgraded to 6.1.1 but the problem persists.
    Does anyone have any ideas?
    btw, I tried hooking my laptop to the Airport Express ethernet connection to make sure it wasn't the PS2 that was the problem. But that didn't work either.
    Please help!!
    Thanks,
    Brad

    I solved my own problem
    The answer is in the FAQ at the following link if you're interested:

  • I just noticed that my ethernet port stopped working.

    I looked, and it seems to be a bit damaged. I also noticed that the power supply chord tends to come loose. How much do you think it will cost to have this fixed at the Apple Store? Will it be worth it?

    To fix the power cord, you will need to buy a new power adapter, or try to bend the external ring on the plug back into shape.
    To fix the ethernet port, you will need to have a new logic board fitted. This will cost hundreds of dollars. If the ethernet port as is works currently, I would leave to live with it.

  • My lenovo G505s shuts down suddenly and key board stops working at times

    Hi,
    I have bought this laptop 10 days ago, I am facing two problems 1st is, it shuts down(suddenly off not proper shut down) while working without showing any error message, and the problem no 2 is its key board stops working at times, system is working fine but all the buttons of key board are not responding. it will work when I restart the system.
    please help what should I do, could it be replaced?

    Welcome to the Lenovo Community !
    Sorry to hear of your problems.  I would suggest that you try a reset of the BIOS just to rule out any hardware conflicts the system may have.  Try this........
    1. Unplug the charger / adapter.
    2. Remove the battery.
    3. Press and hold the Power Button for 15 seconds.
    4. Re-install the battery, plug in the charger / adapter if needed and power up the system to see if the problem was resolved.
    If the problems weren't resolved by doing the reset then I suggest you contact Lenovo Support for warranty service.  Both the problems you mentioned could be related to faulty hardware and the service center would be best equipped to check out your new laptop.  You can find the phone number for Lenovo Support in your country or area by using the link below....

    Hi jju07;
    If you want more suggestions, you are going to have to tell us more information such as exactly what do you in the way of hardware. Any other details to help us help you would go a long way to us suggesting how you might solve this problem.

  • Computer shut down by itself

    I was using the computer as normal. Not doing anything out of the ordinary, when all of the sudden it just turned off. I thought there had been a power outage or something but the monitors were still on. When I tried to restart it I got stuck at the startup screen (spinning wheel and Apple logo) and the fans started getting very loud. I manually shut it back down again and restarted it. It restarted fine the second time, and everything seems to be working, but I'm not sure what happened, or if there's anything I should do.
    Thanks for any help.

  • Computer shuts down 5 seconds after mouse stops moving

    As soon as the computer turns on it comes up with the shutdown/restart box. Have to press escape to cancel the shutdown. If the mouse is moving it is fine but as soon as it stops, 5 seconds later the box comes up and tries to restart. If I let it, it restarts and happens again.
    Any ideas?

    Try a SMC reset.

  • "The Cable for Ethernet is not plugged in": Ethernet port stopped working

    This happened to me on a 17" MBP in April, and now in a new 17" MBP. I find it too coincidental that this has happened RIGHT after several Apple Mac OS X updates this week. I don't believe its hardware as the diagnostics pass. I have tried the computer on several known working ethernet cables and no dice. A survey of the other discussions show this is not an isolated problem, but for me, neither resetting the power management, zapping PRAM, deleting then adding the Ethernet Interface in the Network Sys Prefs, or running Cocktail's scripts and cache cleaning has made a difference. Anyone have another idea?

    I also got my MBP 17 in the middle of April. Everything worked great until around May 9th. Then I suddenly got the "cable unplugged" message for my ethernet, and nothing I can think of will fix it.
    I have tried multiple modems, routers, connections, and cables, along with the suggested PRAM reset, deleting and adding the Ethernet Interface, and everything else I can think of or find online. The computer is going in to IT tomorrow anyways, so I will let you know what they have to say about it.

  • CSS11501 Ethernet Port stops working

    We've had a CSS11501 installed for around 18 months. In the past 8 months we've had three occurrences were we loose IP connectivity on the uplink from the CSS to a Cisco 3560 however nothing has changed. When the issue occurs we are unable to ping the C3560 from the CSS and vice versa and all IP connectivity to servers attached to the CSS is lost from the C3560. The first time this occurred we rebooted the CSS and the issue cleared. The second time this occurred we physically move the UTP cable providing the uplink to the C3560 from port1 on the CSS to port 2 and the problem cleared. We equipment shows no events within the logs.
    I've searched the bug database but have not found anything matching this issue. We are using version sg0810106 (08.10.1.06).
    I would appreciate any advice and a suggested fix from anyone else who may of had a similar issue.
    Thanks,
    Chris

    All I can think off is if they are in auto-negotiate, they could fail to negotiate.
    Can you try to hardcode the speed and duplexity on both the CSS and the router.

  • When I plug in an USB to the usb port my computer shuts down

    I bought my macbook air a couple months ago and when I plug in the usb into the usb port my computer shuts down. I dont know why this happens, but is not always, just sometimes.
    Does anyone know why this is happening?

    Have you tried plugging the flash drive into a different Mac to see if it works? The Air shouldn't have any problem with it, I use a couple of flash drives in mine, although I don't have a pq1. Did you try both USB ports on the Air? Do you have another flash drive you can test in the Air, or a different USB device, like a hard drive or printer?
    The only thing I can think of is either a bad flash drive, or a bad USB port on the Air. Sorry, can't be more help than that.

  • Computer shuts down during render/prerender

    This was not my original problem but it has occured before and I know it will occur again.
    My computer shuts down for no reason when I try to render or prerender video in Adobe Premiere Pro CS4. From what I can tell it is a general issue with premiere that I am having. I have tried multiple video formats, multiple video lengths, and multiple rendering options and I am still getting random shut downs during rendering.
    Here are some specs for my computer which is a laptop:
    OS: Windows 7 Ultimate (64 bit OS)
    Proccessor: Intel Core 2 Duo @ 3.0 ghz
    Ram: 8 gigs of it
    Video: Nvidia Geforce 9600M GT
    1 Hard Drive w/ 280 gb of space
    As a recap.... My exact problem is that during the rendering or pre rendering proccess my computer simply shuts down as in it turns off.
    I can also add that the computer does act strangely leading me to believe that theres some hardware or software incompatibility. While it is rendering I can hear the CPU fan pick up which is usually normal for any rendering application but what I noticed was that it doesnt stop speeding up. Its like if it was going into an overload and I can confirm that at its peak, the computer shuts down.
    To add troubles... whenever I pre render any video and it succesfully renders.... Premeire will hang up really really bad if I try to play the pre rendered preview. In otherwords when you preview a video that it pre rendered it usually plays smooth and everything is fine. After I pre render something though and play it I can tell its locking up because the timeline bar is really jumpy and the video playback skips also.
    This is the problem I would really love fixed. I usually have to button smash my keyboard until I lock premiere up and then once it unfreezes itself i can preview my work smoothly. This is however like a good 5 mins of my time trying to get the preview to play smoothly though so its really hurting how fast I can work.
    If anyone can help me out I would greatly appreciate it. I will be trying to run the same stuff on my older laptop and observe the results. I personally think CS4 is incompatible with windows 7.

    If you have a recent nVidia driver installed, you might want to check to see if you have either of these two modules loaded - check in the nVidia console:
    PhysX, or 3D Stereovision. If you have them, definitely disable 3D Stereo, and test. If no improvement, disble PhysX and test.
    Also, try adjusting your Hardware Acceleration. If Max, set to Min and test. If Min, set to Max and test. If either helps, try incrementing up, or down, until it no longer helps.
    Last, check your OpenGL settings. If ON, turn OFF. If OFF, turn ON.
    It appears that you have a laptop. Is that correct?
    Good luck,

  • Computer shuts down when backing up

    Hello,
    I am using an iMac with Mountain Lion 10.8.3. My Apple Airport Extreme is about one year old (fully updated and current). I am on a DSL connection with AT&T. I am backing up to an external 1.5 TB hard drive (non-Apple brand). There is lots of room remaining on that drive (about 700GB).
    All backups in the past have been smooth sailing with no problem.
    What's happening now are two things (but one of them I think I fixed). At first, Time Machine would try to back up but it would never succeed because it would give a message that there is not enough space available in the drive (it was saying that it needed 10 more GB of free space). But I know that's wrong. I could not figure out how to fix that issue, so I erased the drive completely and started over. Now, I no longer get the "full" message and all appears to be going well----UNTIL......(see next paragraph).....
    Now what happens is that it begins doing the backup process like normal (this would be the first/initial backup since I erased the drive and started over), however, once it gets about 100 GB or so (very rough estimate), the computer SHUTS DOWN. It turns itself OFF. No error window, no warning, no nothing----it just "POOF" turns off. To get it working again, I have to push the power button to turn it back on. There is no error message when I turn it back on.
    I am copying (below) the two most recent Time Machine messages from last night from that neat widget/app that I think pondini invented. I sure hope this helps to diagnosis what is wrong, because I'm stumped.
    The backup log that says "Automatic" is the first one that failed where it claimed there was not enough space to complete the backup. Once I erased the drive completely and started "fresh", that is what the second "Manual" backup is.

    Do a verify of the local disk. The sudden complete failure sounds like a hard disk or memory issue.
    A5 http://pondini.org/TM/Troubleshooting.html
    So the hard disk is plugged into the computer directly?? If not, then I think you should do it that way. Backup to Extreme USB drive is not reliable.
    YOu don't have an error message for the manual backup.. and I am uncertain what the problem is.
    Do a reset of Time Machine. A4.
    And try again with the hard disk plugged into the computer directly.
    You can look at other suggestions on the troubleshooting page.
    eg http://pondini.org/TM/C4.html
    But if you are doing it with the usb drive in the Airport Extreme please read this.

  • After 2 weeks my Iphone 4s shuts down by itself and I cannot  turn it on. What can I do. Itunes is telling me to restore the phone but the phone is saying the software isn't available

    My Iphone 4s  shut down by itself after a phone call and I cannot turn it on. I took it to istore and they said it was unrespinsive and there is nothing they can do? Anyone has a clue what can be done? When I connect the phone to itunes it indicates that the phone should be restored, however when i try to restore it, it says the "software for this iphone is not currently available" Is there anything I can do other than put this brand new iphone in the grabage?

    On computer, at the top of this page is a Tab for iTunes, click it, make sure iTunes is up to date. Also make sure computer Fire Wall and Anti Virus do not interfere with iTunes, turn them OFF to be certain.
