computer goes to sleep as soon as the ethernet cable is plugged in and don't wake up

When the ethernet cable is plugged into my pc, it immediately goes to sleep and don't wake up without a difficult start. As long as the cable is connected, the computer will not load windows, immediately go to sleep before my desktop appears. My laptop is connected wirelessly without any problems at all and when connected with a cable, no problem either. ISP says it's a pc no matter not a modem problem, there is a conflict, but they don't know where.

I am running windows Vista Home Basic, a cisco modem, do not know what model.

Any help would be appreciated.

Once you have performed the steps, restart the computer so that the changes take effect, and then check the result.

Hope this information is useful.

  • T460 touchpad responds liked when the Ethernet cable is plugged

    Hello

    I bought a brand new ThinkPad T460 ten days ago and I noticed that when I plug in an Ethernet cable, the touchpad responds: just a few clicks and taps are missed, the movement is slow and and sometimes temporarily blocked. The touchpad comes alive again as soon as the Ethernet cable is disconnected. The trackpoint and trackpoint button above the touchpad are not affected, only the touchpad starts to misbehave.

    This happens on both Windows and Linux, this isn't a problem of specific operating system. Furthermore, I checked to see if I am running the latest version of the BIOS, and I am. And there are no problems when you use the wireless adapter, but one of the reasons why I bought a ThinkPad was she has a port Ethernet, so not being able to use it would be extremely disappointing.

    I checked to see if there are any IRQ conflicts for the touchpad, but could find none. The problem occurs when the computer is plugged in and when it runs on battery only. I also tried two different cables in the same router, each in a different router port, and the problem persisted.

    I'm using the latest drivers for Windows 7 directly on the Lenovo site, and Arch Linux with kernel 4.4.5 - the Ethernet card is considered:

    e1000e [2.751703]: Intel® PRO/1000 3.2.6 - k network driver
    e1000e [2.751705]: Copyright (c) Intel Corporation 1999-2015.

    Should I expect it is fixed with a BIOS update, or do I have to contact guarantee? It is unacceptable to live with it.

    Tried in another House as promised, and the touchpad works very well with cable Ethernet is plugged. Also, before you leave the House with the problem, I discovered that the problem occurs only when the cable from my ISP switch is plugged into my router.

    Respect my opinion that this machine deserves a stronger touchpad, but apparently is not due to lack of computer - under normal circumstances, there is no problem with the touchpad.

    I'm stumped on how to proceed. Can I use a multimeter on the ISP switch from cable, but I'm not sure what to check (voltage? how does and between what son?). I'll also look into the suggestion of ferrite, I don't know where they are available - this thread is first heard of them.

    Anyway, I wanted to just erase Lenovo name on it.

  • Satellite P300-173 never off when the ethernet cable is plugged or WIFI

  • MB Pro restarts randomly with the ethernet cable is plugged

    I recently bought a thunderbolt reduction - Ethernet [1] and it works very well. The problem is that when it is plugged in, my MacBook Pro (13', 2015, i5, 8 GB) gets very hot. This isn't a problem, but the next thing is really annoying.

    Whenever I'm not load, but the ethernet cable is connected, and MacBook goes into sleep mode, the system turns off instead. Thus, for example, when I don't have the power cable and if go for 5 minutes, the system automatically sets the mode 'sleep'. When I come back, it is turned off, and when I hit the power button, a black screen with the Apple logo and a text in several languages, saying that the system restarted because of a problem. After that, MacBook starts normally.

    The same phenomenon occurs:

    • When the power cable is not connected and I close the screen
    • When the power cable is not connected and I SLEEP manually the MacBook
    • When the screen is closed and I plug the power or the ethernet cable

    I use OS X 10.11.

  • When my computer goes into sleep mode, I have to press the power button to turn it back on.

    original title: sleep/hibernation

    When my computer goes into sleep mode, I have to press the power button to turn it back on.  I used only having to press a key on the keyboard.

    Can someone tell me how to solve this problem, as if it was before?

    Well, on the theory that your computer is awkward, try to change the settings to another thing and OK your way out the control panel.  Then go back and put them in the way they were and OK your way out.  Occasionally, it will reset the internal parameters and things can return to normal.

  • Computer goes to sleep and won't wake up

    A few days ago my computer started not to wake sleep cycle.  It goes into hibernation and don't wake up with a jerk of the mouse or by pressing the buttons on the keyboard.  I put the display to sleep for 4 hours and 30 minutes, but she falls asleep before 4 hours are rising and then don't wake up upward.  I have to press the button for a few seconds to do to turn off and then restart.  If I press a button on the screen when the computer is in standby it gives me a message that the signal of the computer has been lost.  Anyone has any ideas how to solve this problem?

    Hello

    Look at all the features associated with sleep and ensure that it is only sleeping and not hibernate.

    Some computers sleep mode will not let you wake up mouse etc. You have to push short s to the power Witch (as mentioned above by WillTel).

    It is possible that your computer never before slept and was just to go off the screen.

    Hi BSRC$, in stock

    1. You have security software installed on the computer?
    2. You receive an error message when you restart the computer?

    Reinstalling Windows XP to the factory setting would not be the first option.

    It is possible that some third-party programs or the services installed on the computer interfere with the installation of service pack 3.

    I suggest that you try to uninstall service pack 3 from the computer by using the recovery console and subsequently ask the article below for what to do before installing the service pack 3on the computer.
