Why does my external monitor name and resolution change when I close the lid?
When I close my lid on my early 2001 MBP, the external monitor reverts to a lower resolution. I am not even able to select the proper resolution.
I am using VGA (I need VGA for my KVM). When the lid is open, the monitor sees the correct monitor, and I can set the correct resolution. When the lid closes, it only shows a genertic VGA monitor and defaults to a lower resolution. I am not able to change the resolution up when I have the lid closed as well. Does anyone have any insight into this?

Why won't my MacBook Pro go to sleep when I close the lid?
All of a sudden, my MacBook Pro has stopped going to sleep when I close the lid. Instead, the indicator light on the front stays on steadily. When I then open the lid, I am asked to log in again, but before I can type anything, the window goes completely black. My only choice at this point has been to hold the power button down long enough to shut the laptop off. Then I wait a minute or so before restarting. Is there a setting I need to check to prevent all of this from happening? I have tried restarting in Safe Mode, then restarting normally, but still the laptop will not go to sleep when I close the lid.
Some process is impeding the sleep function. Since you've tried rebooting and it persists, check and see if Time Machine is hellbent on completing a backup, cause it can have that effect.

How do i run an external monitor with my macbook and change settings so that when i close the lid the signal to the monitor is not lost and i can continue using the mac with a mouse and a wireless keyboard?
No, nothing will prevent the computer from going to sleep when you close its display except third-party hacks that are designed to do exactly that. I strongly advise against using any of those, as they may interfere with successful entry into clamshell mode (and they carry other downside risks as well). Just wait until the computer is asleep (with its sleep light pulsing), then press any key on the keyboard. It sounds as though your setup is working as it's designed to do.

Hey, I am new to mac and still getting used to it (making the transition from windows), its amazing! Anyhow, I cannot figure out why my itunes and other media like youtube or a film on vlc player continues to play once the lid has been closed. I thought that when i close the lid the macbook should then sleep. It does everytime when there is nothing playing. The little white light on the bottom right hand corner of the book is on but music continues to play.
The sleep option always works. If I press the power button and choose the option sleep it does so etcc.
Is this normal and am I just being stupid or is there a problem??
I bought the laptop from ebay, its a macbook pro late 2011 17inch. I dont have apple support and might have to make a trip into London to the mac store however I was hoping someone can help me...
Processor 2.4 GHz Intel Core i7
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
Software Mac OS X Lion 10.7.5 (11G63)
Thanks if you can it is muc appreciated....!!hey, thanks for the reply. I don't know to be perfectly honest. When I close the lid without any music playing it sleeps fine. How could I check?
So basically I pressed the power button and pressed sleep. The laptop turned off and the little white light turned on no problem. I did the same thing with closing the lid and it went to sleep no problem. (Can you confirm that when the little white light is on it means the laptop is sleeping)??.
I then had itunes playing and pressed the power button and when i pressed sleep the music paused then 6 seconds later it went to sleep. I then had itunes playing and closed the lid and the music kept on playing even though the white light was on.

Why does my iTunes stop playing when I close the lid on my laptop?
I am playing iTunes on my Vista laptop and my setting are 'do nothing' for both powered and battery use, but when I close the lid iTunes stops playing music. Does anyone know why and how I stop it? Please don't say "don't close the lid..." Thanks.
You have your answer... there is no way to stop iTunes from stopping playing music when the lid is closed.
You can try adjusting the power settings, but if that's not working...there is no way for iTunes to override it. -
A rundown of what I've tried:
Adjusting energy settings to try to prevent sleep
Pluging the USB keyboard and wacom tablet directly into the laptop (as opposed to a usb hub)
My laptop's power cable is connected
My display (a Vizio TV) is recognized in the System Preferences panel
I'd been using this TV for about a year with my older Macbook Pro (OS 10.5.8), though using a different wireless keyboard and mouse
***Update: The issue seems to lie with the keyboard and wacom tablet. I am trying to use a wireless Case Logic keyboard (with dongal) and wired wacom tablet to wake the Macbook Pro in clamshell mode. To experiment, I tried using my Logitech wireless keyboard & mouse set (also dongal) that I had been using before and it wakes the computer without any problems! However, I really need to be able to use my wacom tablet. If I switch to the tablet after waking the computer using the Logitech keyboard & mouse it works, but once the computer sleeps it won't work anymore. I could keep switching back and forth I suppose, but it's sort of a pain. There has to be an easier way! Any ideas why the wired wacom tablet is unable to wake the computer in clamshell mode?
Thanks!So your keyboard or mouse won't wake the Mac when you close the lid correct? Try resetting the SMC and pram

Why does Messages still send my txt via SMS when I have the "send as SMS" option turned off?
Why does Messages still send my txt via SMS when I have the "send as SMS" option turned off?
I haven't missed any point, but you don't get it.
If people take "Send as SMS" being turned off as the iPhone shoiuld not be sending SMS messages without reading this text that is included below the option:
Send as SMS when iMessage is unavailable. Carrier messaging rates may apply.
They are idiots.
But you're saying you have this other piece of information that tells you that this option only applies to two iphones exchanging txt. Where did you obtain such information?
Copied from my previous post.
Under the Send as SMS option, the following is available:
Send as SMS when iMessage is unavailable. Carrier messaging rates may apply.
You should check available text below an option such as this so you know what it does. -
Why does my laptop turn itself off when i close the lid?
i have a HP pavillion dv4 notebook. sometimes when i close the lid and let it go to sleep, and then come back to use it, the computer is off. i get a weird DOS-like black screen with white text when it comes back on asking me if i want to start windows as normal or something like this. has anyone encountered this? does anyone know how to fix it?
Try resetting the iPod. Nothing will be lost.
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
You can also try another cable and usb port. -
I have a Samsung VGA Monitor connected to my MacBook Pro using the Mini Display Port to VGA Adapter. How do I configure the computer so that it doesn't sleep when I close the lid of the computer.

This article may provide some information about your Mini DisplayPort to AVI adapter. Have you tried to connect a different VGA monitor to your Macbook to see if you get the same results?

http://support.apple.com/kb/HT3382
18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

How can I detect displays?
If the detect displays option is not available, hold down the Option key while you are in the Display pane.
How do I select additional resolutions on my display?
You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
I hope this information helps ....

Does not sleep when I close the lid...
Never encountered this before! I have 1 MacBook that works fine, but bought another today that will not sleep when I close the lid. It does sleep when I select it from the menu, but not when I shut it.
Any ideas?Mine recently started doing the same thing. Now everytime I want to go out with my computer I have to pack up the charger, even if I only end up using it for 15 minutes, because the battery is wasted by 2.5 hours.

Boss bought a new monitor for his mac book. We connected it but he rather keep the mac book lid closed in order to work on the bigger monitor screen. Soon as he closes the lid, the mac book goes to sleep mode.
Is there a free way to disable the sleep mode?When the MacBook goes to sleep just hit a key on your external keyboard and the monitor will come back on.

Macbook Pro:
When I raise the lid after sleeping, the screen comes on momentarily then backs out. If I close the lid and raise it again, the same thing happens. It is sometimes necessary to force quit. Once restarted, there is no problem unless the lid is closed for a short time and the machinge goes to sleep.
