External monitor is no longer wakes from sleep (10.11.2 updated)

I have a LG external LCD - LED group connected to my Mac Pro via HDMI 2013.

No problem with no display at all before sleep... but since the 10.11.2, update it just don't wake up from his sleep and I have to force a reboot. I've since turned display sleep off options and I now use a screen saver protected by password instead (of security) and simply turn off my screen with the power button.

I had this problem too with the Beta 2 and Beta 5 from 10.11.2. Both times I started 10.11.1 Time machine, hoping it would be fixed in the final version.

Before that everyone says, the following link is not welcome... I has not come down in the last shower: If your Mac does not sleep or wake up when expected - Apple Support

It's certainly something that has changed in El Capitan 10.11.2. I now have a beast + $10,000 a computer that can not put its own screen of sleep

Exactly the same problem with my mac pro and panasonic plasma hooked up via hdmi. Worked fine before the update. Now, if I turn off the monitor, I have to reboot to get the screen to display an image, once it comes back on.

  • Monitor intermittently do not wake from sleep mode

    I have a new Pavilion 500 - 205t Windows 7 Desktop (two weeks).  Two days earlier, after the computer is in mode 'sleep', the computer would wake up, but the screen would not.  I contacted HP Support and they said not to put the computer in mode 'sleep', but to turn it off instead.  They said that the computer could accumulate a static charge which could prevent the monitor to wake up from sleep mode.  Their solution was to force a shutdown by pressing the power switch, unplug at the back of the Tower, by pressing the power switch for 20 seconds, plug everything back in and then turn on the computer.  The monitor worked correctly then wake up from sleep mode.  For the last two days, the computer would wake properly from sleep mode.  Today, the same thing happens again.  This time, I turned off the computer and then he turned back to (without unplugging everything) and the monitor worked correctly.

    Here's my question:

    Is it really a static problem? (It has been cold and dry here for several weeks and static is high)  Or I have a hardware problem or software that needs to be fixed?  Thank you for your time.

    I think I found the solution to this problem for my computer.  I changed the settings for sleep or sleep 'Hybrid' or 'Hibernate' is allowed.  Since then, I have not experienced the problem.  I also changed what does the power button, so that when I press the power button, the computer shuts down normally.  This prevents a "forced" shutdown if the problem happens again.

    Thanks again Bill, for your time.  I mark this problem is resolved.

  • Computer won't wake from sleep after installing the update July 2013

    Original title: a reason any after July 2013 windows update mode "sleep" freeze my computer

    Before I wake up problems due to incompatibility with windows 7 and SATA Hard drives (WD). This problem has been fixed with Windows Update August 2012.  Just recently after July 2013 Windows Update. After that my computer is in mode "sleep" for a certain time it freezes and will not restart until I press and hold the power button until the computer turns off. Then pressing the windows button star as a "Recovery Windows" message will appear.

    I blame the July 2013 Windows Update. But I can't be sure what it causing the problem... I cleaned the Reg via CC & norton util 16 more run antiwalware Malwarebytes and run a Norton virus check. the lock in question remains.

    Any ideas?

    Problem solved... I had added a USB 3.0 Hub to my system. Unfortunately I do not share this Yauqb, thinking that a USB problem would not cause the fault that the USB (connected devices to the) worked well, my lack of this info likely extended the solution time.

    Somehow that it finally dawned on me that look at the manufacturers site hub, of course nestled in the catacombs of the FAQ is a text of presentation all by unchecking the checkbox in the section of wake-up USB Device Manager.

    When you look in Device Manager, USB devices are not the easiest to deal with because there are many multiple subdivisions more with no name and only cryptic blurbs attached when you look in the properties. Lucky a USB 3.0 arrives as 'High Speed' which reduces my 3-point action fields, uncheck all sleep problems fixed.

  • (Redirected) XPS 13 Ultrabook wake from sleep!

    Hello!

    I have a Dell XPS 13 ultrabook I love, apart from a major problem. I can't seem to wake from sleep using the keyboard or the mouse. I never had this experience with a laptop before.  It is a pretty big problem, I use the XPS 13 has docked at the D3100 docking station and connected to an external monitor, keyboard, and mouse.  I keep the laptop with the screen closed and just use the external Setup - as you usually would when it is docked. Everything is fine until the device goes to sleep. If the computer is still on, but just the external monitor is turned off because the power settings, and then moving the mouse/hit the keyboard to wake the rear monitor. However, if the computer is idle (NOT put in hibernation), it nothing happens when I move the mouse or repeatedly hit the keyboard. I need to get out the ultrabook the cubby that's in, open, hit the power button, then close and replace. He gets the computer turns on again, but is incredibly annoying. As a side effect of this, all my windows get resized and my icons moved the Office because the latop temporarily switches to the built-in screen (which is at a resolution lower than my external monitor) before returning to the external display. I had the Latitude laptop for years without any problems and was disappointed with this experience. I really hope that there is some sort of fix.

    So far I have tried:

    1. connect the receiver of keyboard/mouse wireless in all USB ports on the ultrabook itself and also the dock of the D3100. No difference is made.

    2. try with a wired keyboard and wireless. No difference is made.

    3 tent to shoot to the top of the mouse/keyboard power management settings in device management and ensure "Allow device to wake the computer" is checked. Not possible, "Power management" tab appears now available in Windows 10 in the device properties window.

    Help, please!

  • How can I PREVENT Time Machine back on the wake from sleep?

    I leave my machine on the work week and when I finished the night, I SLEEP there.

    In the morning, he has no need to backup first thing. But Time Machine insists on execution from the moment I have a mouse and he wakes up from his sleep.

    It was fine when it was new and fast, but now he is old and slow (especially - but mostly because I really push to the limit with multiple Safari Windows opens and executes a large number of software design at the same time, I have to do for work).

    My question is simple:
    How to tell Time Machine to does not have a return on the wake from sleep? or;
    Say this do not back up from 06:00 to noon? or;
    Is it a third party plug in that allows me to customize the time Machine more?

    Another idea on what just said or it to no return for even the first hour or two when it comes in the morning or even in any time to sleep during the day. Automatically.

    I also have my drive main external file mirroring AND use Super Duper once per day to fool the internal drive (I total plan control) AND back up all files off site (I total plan control). But, Time Machine is also always at hand to get it done. If only I had a little control over it, so she did not have the necessary step back up the minute I sit down. Significantly slow down my work time productive morning!

    Time Machine really shouldn't bog down your machine that badly.

    If Time machine running interferes with your ability to use the machine, then something else is wrong. It shouldn't affect performance in this way.

    If it's all just "annoying"... Well... Why is this a big deal?

    Maybe you should run a report Etrecheck and post the results here. If something is moving your system, which can help us identify what it is.

  • Fallout 3 stops working after the computer wakes from sleep

    Since the games for Windows Live 3 is out, Fallout 3 has never been the same. He used to work at best my GfWL and now her nightmare. Recently, after that I quit the game and put my computer to sleep, Fallout 3 will stop working completely after wake up. I try to start it and I get them all is a cursor with a small blue rotating light. What is even more strange, is that my computer goes into a State of semi who no longer meet this point where programs and keyboard shortcuts no longer work, but I can browse my hard drive. I try control + SHIFT + ESC to see what the devil but that causes Windows Explorer to stop working. CTRL + Alt + Delete does not work either. No matter what I try, once I start Fallout 3 after the computer wakes from sleep, I can't do the task to the top manager and I can't use my computer. The only way to get it is to hit the reset button or turn off manually. Can someone please help to get rid of this problem?

    Hi murphy449,

    1. did you of recent changes on the computer?

    2. the problem only happens when you start fallout 3 after the sleep mode?

    3. are you able to wake the computer quits successfully sleep mode?

    4. What is the version of Windows installed on the computer?

    Method 1

    I suggest that you manually download and install the latest drivers for display on the computer card and check if it works.

    http://Windows.Microsoft.com/en-us/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

    Updated a hardware driver that is not working properly

    http://Windows.Microsoft.com/en-us/Windows-Vista/update-a-driver-for-hardware-that-isn ' t-work correctly

    Method 2

    If the previous step fails then I suggest that you try the clean boot procedure to check whether a third-party program installed on the computer is causing the problem.

    To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    (a) click Start, type msconfig in the search box and press ENTER.

    (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

    (c) under the general tab, click the Normal startup option, and then click OK.

    (d) when you are prompted to restart the computer, click on restart.

    If the previous step fails then I suggest you check the observer after return with details and events for the cause.

  • Satellite U500 - may not wake from sleep

  • eHome IR transmitter fails to wake from sleep

    I am running Windows 7 64 bit on an HP box bought less than a year ago.  A Hauppauge 2250 tuner card is installed.  The tuner card is connected to my Comcast Cable box by an IR transmitter.  The system worked well for months, but now I find that the IR Transmitter is not working after coming out of sleep mode.  Reboot and everything works well again.

    How can I get the IR transmitter to continue functioning when the computer wakes from sleep?

    THX,

    first thing to do is to try a system restore to the last time it worked.

    My configuration:

    T400 (2767-14U)

    Windows 7 64 bit

    256MB ATI Radeon 3470HD (switchable graphics in 'High Performance')

    Docking station advanced (2503)

    Monitor of D221 Lenovo's (using the VGA cable)

    I used the configuration above without problems for a year.

    My problem:

    I just replaced my hard drive, clean installed the operating system and all applications and updated all the drivers and BIOS using the system update. Since then, my external monitor is no longer lights up when I start my computer in the dock (lid closed). The only way I can get the monitor external to work is to start my computer first and then "hot dock" it.

    As far as I know, all my BIOS/power/graphics settings are the same as always.

    Thanks in advance for any help!

    Thanks for your quick response.

    I thought of that also, but it isn't that...

    After I posted the above, I realized that something was different was that I had installed this time logins.

  • my computer would not wake from sleep when the cover iclose & open again?

    Hi George,.

    From the description of the problem, it seems that the computer would not wake from sleep when you close the lid and open it again. I understand the inconvenience.

    Method 3: Update Chipset drivers

    Method 4: Run the BIOS update

  • Why Edge E430 wake from sleep?

    My new E430 Edge wakes from sleep inexplicably.

    Under the power plan, I have timers wake disabled for battery and AC power. Under scheduled tasks, I went through each scheduled task and not one "allow the waking from sleep" checked. Yet the machine spontaneously wakes up from his sleep (i.e. without human intervention) after 3 hours.

    How can I determine which task is originally wake? (Is it conceivable that could do it my LAN?)

    Maybe it's a coincidence, but: in Lenovo Power Manager 6, on the Global tab, I've disabled USB case and 30 days of standby. Since then, the machine remains asleep (without even a Lullaby).
