Closing CR-48 lid causes external monitor to shut off.

My screen broke a few weeks ago and I have been using it with an extra monitor as a desktop. I'm running xfce and can't seem to find the option to keep the screen from going black when the lid is closed.

This is how I do it. I have the external monitor hooked up and ready to go. Then I close the MacBook. Once it goes to sleep just use your extenal mouse or keyboard to wake the MacBook. This will make the external monitor the main display.
When you open the MacBook it's display will be off. If you decide to turn it back on the easiest way I have found is the display settings in system preferences.
I pick the Show displays in menu bar. That way I click the display icon in the menu bar. The first choice is detect displays. Click it and it will wake the MacBook monitor and both monitors will return to normal.

Closed lid and external monitor

I've been using an Envison external monitor with my G4 PB's lid closed. While surfing the web I think I must have accidentally hit some strange key combo because my monitor screen went dark (no signal) Restarting the computer (closing the lid once start up commences) everything works fine with the external monitor until I log in at which time I get a no signal warning and the screen goes dark.
Perhaps another item, when I close the lid the resolution on the monitor changes.
Al PB G4 Mac OS X (10.4.8)

found power plug disengaged...once plugged in everything worked as advertised.

Macbook Pro Retina (late 2013) & 10.10.1 cannot detect the external monitor is turned off

I connect my MBPr (late 2013) to a 24" Dell monitor via HDMI using a high quality audioquest hdmi cable.
When I turn off my Dell monitor, the MBPr did not detect the monitor is being turned off.
Let's say I opened a chrome browser and I move it to the external monitor. If I turn off my Dell monitor now, the chrome browser will not automatically move back to the MBPr screen.
I have the same scenario if I just power on my MBPr now and not power on the Dell monitor. I will do this if I need to do some small stuff (like typing this post) int he middle of night and I don't want to turn on my Dell monitor.
I am not sure if this is a problem or this is a normal behaviour of the MBPr. I was like this when I was on Mavericks.
PS. If I connect my Lenovo laptop to the same monitor and I turn off my monitor, the opened applications will go back to the Lenovo screen.

The hardware supports DP1.2 and MST but unfortunately at present OS X Mavericks does not.

Monitors keep shutting off

I have a Mac Core 8 with two 23" monitors that I bought about a year ago.
For the last few months, both monitors will suddenly go black for no apparent reason.
The computer isn't going to sleep as the applications are still running and the hard drive still begin accessed.
(for instance, if I'm running music software, the music keeps playing) and the power lights on both monitors stay lit up.
Once the monitors go black the only way to get them working again is to power off the computer using the power button, and then restart it again several times.
Usually the process takes about 3 to 5 restarts.
The first time I restart, I get the startup chime but the monitors stay black.
The second time, maybe just the left monitor will come on.
Then on the next attempt, only the right monitor will come on.
On the final attempt, the right monitor will come on by itself, and then about 10 minutes later, the left monitor will come on as well and I can finally use the computer again.
I can't shut the computer down or I end up having to go through this whole process again.
So… any ideas on what the heck is causing this?

Quit/close all apps completely and restart the iPad. If this helps, make note of the app that you last launched if the iPad crashes again and assume that app is the culprit causing the crashes.
Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
You can also try rebooting the iPad and see if that helps. Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Forcing the monitor to shut off -- fixed!

Usually when I walk away from my computer, I shut the monitor off manually with the power button. However, the button is quite finicky, and I'd rather have an entry in my root window to shut off my monitor.
So I figured out that the xset program can do this. 'xset dpms force off'
But... all this does is make the screen go black. Once I move the mouse, the screen comes back to normal. 'force off' should shut the monitor down completely. I've also tried 'force sleep' and 'force standby'.
'xset q' reports that dpms is enabled. If i get the monitor status after I 'force off', it says the monitor is off, but it clearly is not.
I'm running the standard arch kernel26, with xorg, nptl, udev, hotplug. I'm not running xscreensaver, if that makes any difference.
Maybe I need to install a module? This worked at one point, and that's probably when I had my custom kernel with everything built right in. I just tried modprobing acpi, but it reported there was no such device. and it couldn't find an apm module.
I'm running modern hardware, so I don't think there's a need for 'acpi=force'.
Anyway, thanks in advance for your suggestions

heh well first of all, i have a brand new athlon 3000+ machine, running on an asus motherboard, and I've used power management on hardware older than yours.
According to dmesg, ACPI is enabled, meaning the BIOS supports this feature.
I've run xscreensaver with power management on here before, and it would shut the monitor of. As I said in my last post, this method doesn't work now.
I don't want to point fingers, but I think that perhaps there's a broken package preventing this from working... most likely kernel26 2.6.8.1. Perhaps if we can get some feedback from users for whom this IS working, we can figure out what the problem actually is.

HT1339 My Ipod causes my PC to shut off completely...any help? I was trying to restore it because it erased all my content when i tried to add a few new albums...Now it shuts off my computer minutes after I connect.

When I plug in my IPOD, Windows crashes and my computer reboots...
Before I got to this point, I unsuccessfully attempted to restore my IPOD a couple of times and tried to reload my music but to no avail.

Hello there khary9,
I have an article that talks about troubleshooting USB ports that may be helpful in this situation. Named iOS: Troubleshooting USB connection it can be found here http://support.apple.com/kb/ts1286.
Once you determine that your computer has a USB 2.0 connection, use the following steps to troubleshoot the connection between the device and the computer. Test after each step:
Update to the latest version of iTunes.
Plug the device directly into a high-power USB 2.0 port on the computer. If possible, use a USB port on the back of the computer.Avoid plugging the device into a keyboard, display, or standalone hub. The USB ports on these accessories may be low-power or only offer USB 1.x connections.
If you are using an accessory, remove the device from the dock and connect it to the computer using only the Apple USB to Dock Connector cable.If you have access to additional Apple USB to Dock Connector cables, try testing with another if the first one doesn't work.
Restart your computer and device. To restart your device:Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the Sleep/Wake button to turn it back on.
Disconnect all USB devices from your computer, except for your keyboard and mouse. Then reconnect the iOS device. If the issue is resolved, reconnect other USB devices, testing after each connection.
Another article describes what to do if you are using Windows and see an unknown error containing "0xE" when connecting your device.
If the issue persists and you are using virtualization software to run another operating system alongside Mac OS X, quit that software; it may create virtual USB ports that may be causing the issue. Or you can try to control or restrict access to USB ports while running the virtualization software.
Cheers,
Sterling

HT5361 I am having trouble with closing the mail app so that I can shut off my laptop. the menu bar under file doesn't give me the option to quit. that option is lister, but it is faded. command Q will not close mail either.

I am unable to shut off my laptop because I can not close the mail app. Command Q doesn't work. While "quit mail" shows up under FILE on the menu bar, it is faded and not a working option. Mail appears to be frozen. I also can not pull up the mail page despite the app being open. Clicking on the mail icon does nothing and there are no available options under the menu bar. Help, please! Thanks!

Try force-quitting (command-option-esc).

Using an optical cable causes Bose system to shut off

When I use an optical cable to play ATV2 through my Bose surround sound system, it turns the Bose system off after a few seconds. The Bose system works fine with the other components.

I just use mac the ripper with the following instructions
http://www.ripdifferent.com/phpbb2/viewtopic.php?t=1249&sid=de5cc9506c05b6ba98d6 530884489333
It gives you a few options for audio, I generally save as AAC though you can rip as AIFF and then encode into just about anything with quicktime.

Song causes my ipod to shut off...please see details

I have an ipod shuffle first generation that I've had for 2 years and nothing like this has ever happened before. I downloaded new music to my ipod and when it gets to a certain song, it just dies. I can hear a faint click and then it just shuts off. Last night, I noticed that after this happened, there were two tiny dots, one green and one orange, right on top of the other where the green power dot usually is, but much smaller. I tried to take the song off, but the ipod still cuts off in that spot. To get it to play again, i have to click it off and then on again, which resets the whole thing. Did I download a bad song(it was off of itunes and it downloaded normally) or is there something wrong with the ipod?

What version of firmware is your shuffle running? See Settings pane...
If you know the name of the song, do File>GetInfo>Summary and tell us what it says.
It may just be corrupted...

External monitor with closed clamshell without mouse

Hi,
I use MacBook Pro with a non-Apple monitor (via VGA adapter) which is easily detected and performs screen extension and mirroring well.
I have wireless keyboard from Apple and pen & touch tablet from Wacom, both connected.
When I close the lid, the external monitor always goes to sleep (miror mode and extension mode) and is not activated via keyboard (Bluetooth activated, devices can wake the computer via Bluetooth).
Do i definitely need a mouse or is the problem in something else?
Thanks in advance!
RR

Maybe this will help. If you monitor the "More Like This" box (top right), other threads appear. Opening them usually displays other threads.

Can't get external monitor to work

I've used a Mac laptop for the last 8 years, finally decided to get an external monitor for home use.
I purchased a 25" Hanns-G HZ251. It's not working as I would expect it to work. I've got a standard DVI connection on my older MacBook Pro so I'm connecting via a DVI to DVI cable.
The only way I can get the monitor to display what is actually on my laptop is to have my laptop open and mirroring turned on. I thought I could have my laptop shut and the monitor would still work when connected, but when I shut my laptop it just goes black.
If I leave my laptop open but turn mirroring off, I get the generic purple Mac desktop, not my desktop.
What am I doing wrong?
There's an install CD that comes with it, but that only runs on a Windows machine. I appreciate any advice, I'm fairly technically handy but this is my first foray into using external monitors, so I'm definitely struggling to figure this out. Thanks.

You will have to keep them both open and play around with monitor settings until you get them both working. Keep doing "Gather windows" in System Preferences to get the display preferences window for the 2nd monitor and change it each time it doesn't display anything.
I don't know what it means "you will have to set it".
You have to set the desktop for the additional screen. Once you get closed clamshell to work, the external monitor will be your primary screen and you won't have to worry about it.

W520 external monitor not connecting properly

W520, Windows 7 (64 bit), NVIDIA Quadro 1000M 2GB DDR3, purchased November 2011. External monitor: HP 2511x.
Haven't been able to find this issue in a previous thread.
In Optimus (preferred) mode, when I plug an external monitor VGA, HDMI or DVI (via displayport) cable into the laptop or mini dock, the laptop LCD goes completely dark (black). This happens whether the external monitor is turned on or off, for the VGA and HDMI plugs. If the external monitor is turned off when the displayport plug is inserted, nothing happens: the laptop screen stays on, but when the external monitor is turned on, with the displayport plug in use, the laptop LCD goes dark.When the plugs are removed, the laptop LCD comes back on, except when the displayport plug is removed (then, the laptop screen stays dark).
In all cases, the external monitor is not recognized by the laptop, and if turned on at the time (the external monitor), shows a message which reads that it is going to sleep.
Device Manager shows the Intel and NVIVIA display adapters and does not show the external monitor (because I cannot hook it up without darkening the laptop screen).
A few months ago I had the Optimus arrangement working, using the NVIDIA control panel to set up a clone mode. The external monitor worked beautifully. Then I disconnected from the external monitor for several weeks, and now it will not work.
The external monitor was used until very recently on a separate PC, which I no longer have, and the external monitor driver was reloaded this morning.
I welcome sugestions on how to plug into the laptop without causing the laptop screen to go dark, which I think would then allow me to set up the external monitor as desired.
Thanks,
RR

But did you RUN the nVidia driver file that you downloaded??? It is an EXE, and you must RUN it after downloading.
The fact that your Device Manager -> Display Adapters still shows "Video Controller(VGA compatible)" specifically tells us that you have NOT YET INSTALLED THE CORRECT DRIVER FOR YOUR VIDEO CARD!!! You are still running with the vanilla generic Microsoft VGA drivers which will work generically and support only minimal capability for EVERY SINGLE VIDEO CARD MANUFACTURED. It doesn't support all of the capabilities of the K1000M.
YOU MUST ACTUALLY RUN THE DOWNLOADED DRIVER INSTALLATION FILE EXE, in order to perform the process of actually installing the driver for your "Video Controller(VGA compatible)" device, which of course is really the K1000M.
Once that driver is correctly installed, it will now appear as "NVIDIA QUADRO K1000M", instead of "Video Controller(VGA compatible)" as you currently show.
The reason your desktop icons are currently very big, and that everything else is currently very big/enormous, is because your desktop resolution is not set correctly... although it may be set as high as it can go for the moment. Only when you finally install the true nVidia driver will your default resolution be presented at what the hardware monitor "recommended" resolution should be, which is likely at least 1920x1080 if not 1920x1200. Then everything will appear "normal size", and at the very least will not appear to be ENORMOUS as you currently see.
Also, I'm expecting that once you get the correct nVidia driver installed for the K1000M that your external monitor will now work perfectly, and will not black out.
So... even while you're still using the current vanilla generic MS VGA driver (although again, your mission is to install the nvidia driver for your K1000M), just right-click on the desktop and select "screen resolution" from the popup menu, to get the "screen resolution" dialog window.
Then click in the "screen resolution" dropdown list to get a dropdown (with a slider) offering you to change resolutions. Pull the slider up to whatever you want and click, and then push the OK button. You'll then be offered a confirmation dialog window allowing you to click OK or CANCEL within 15 seconds to accept the resoluton change. Click OK to keep what you just set.
Your desktop icons and everything else will now appear smaller (or at least "normal"). Temporarily, you've got things satisfactory at least.
But you'll do the same thing again AFTER INSTALLING THE NVIDIA DRIVERS. This time the dropdown "screen resolution" list will have a slider whose top value will show "recommended", and will probably be 1920x1080 or 1920x1200. Pull the slider all the way up to that value and click. Then again, push OK, and OK to the confirmation.
Again, your absolute test goal is to see "NVIDIA QUADRO K1000M" in Device Manager. You should NOT BE SEEING "VIDEO CONTROLLER (VGA COMPATIBLE)".
The installation of the nVidia driver will also get you "nVidia Control Panel", where you can then perform additional customizations, such as whether or not you want to use BOTH the laptop screen as well as external monitor configured in either "laptop screen only", or "clone mode" (i.e. duplicate of single desktop on both screens), or "extended mode" (i.e. double-wide desktop extending across both screens), or "external monitor only," (with laptop screen dark).
Again... YOU MUST RUN THAT DOWNLOADED NVIDIA DRIVER INSTALLATION FILE EXE. It doesn't run itself, unless that's what you have set in your browser when offered the choice of RUN or SAVE. But if you SAVE it, then you must yourself manually run it after the download completes.
IT MUST BE RUN TO INSTALL THE DRIVER. Then you'll see "NVIDIA QUADRO K1000M" in device manager. Until and unless you see that value, if you still see "VIDEO CONTROLLER (VGA COMPATIBLE)" then you have NOT YET DONE WHAT YOU NEED TO DO.
Understood?

SNOW LEOPARD - macbook pro with external monitor

My external monitor (Formac DVI) is giving me problems since snow leopard - if I start up and close the lid the external monitor goes black with thin grey lines. I have to keep the lid of the laptop open until start up is complete and the desktop appears on both monitors, then close the lid, let the comp go to sleep then wake with my bluetooth keyboard that's very annoying.
What are the chances this issue will be fixed soon?? I may go back to Leopard for a bit.....

I found the solution to this problem on another website, tried it and it worked!!!
10.6: Re-enable LCD font smoothing for some monitors
Mon, Aug 31 2009 at 7:30AM PDT • Submitted by astrosmash
There is a bug in Snow Leopard that disables LCD (sub-pixel) font smoothing on many third party LCD displays, including models from Dell, Samsung, LG, HP, EIZO, and Lenovo. Here are the details:
Snow Leopard introduces simplified Font Smoothing options under the Appearance pane in System Preferences. Prior to Snow Leopard, the available options were:
Automatic - Best for Main Display
Standard - Best for CRT
Light
Medium - Best for Flat Panel
Strong
In Snow Leopard, you can only choose between Automatic and Standard CRT. Since few people use CRTs these days, most users now have only one option: Automatic. The problem with the Automatic option is that OS X incorrectly detects many third party LCD monitors as CRTs, and consequently, disables LCD font smoothing.
You can force OS X to use LCD font smoothing on all displays with this Terminal command:
defaults -currentHost write -globalDomain AppleFontSmoothing -int 2
The number 2 here corresponds to Medium - Best for Flat Panel. You may also use 1 for light smoothing, and 3 for strong smoothing, as per the original OS X font smoothing options.

2010 Macbook Pro 17 display on external monitor only after power on

THis has happened a few times over the past 6 weeks - I power on first thing in the morning and the primary screen is black, and the login screen appears on the external monitor. Shutting it down and starting up again does the same thing. When it happened before I'd power off, remove the external display, power on and then I'd get the primary display back agin but it's not working this time and I've only got the external display working.
Is there a utility to 'kick' the graphics into the correct mode, or is this some type of hardware problem?
Thanks,
Graham

The primary laptop monitor starts blank, and only the external monitor is working.
If I shutdown, unplug the external monitor and power back on the laptop screen stays blank. If I plug the external monitor in the screen that would normally have been on the primary laptop screen is on the external monitor, and the laptop screen remains blank. At this point I can only work with an external monitor plugged in, and that limits my portability a bit

External monitor usage with Satellite A100-PSAA9

I have a problem when I connect a 2º external monitor, it connect but next it disconect , it's always connecting and disconecting. I made the update of display driver and bios but I still have the same problem, what can i do?
My operating system is windows vista.

What do you mean exactly with disconnecting and connecting?
Does the display switch to the internal and external display or the display on the external monitor goes simply off.
Did you check the connection to the notebooks monitor port?

Closing CR-48 lid causes external monitor to shut off.
