Closed mode glitch

For a couple of weeks I’ve been very successful in using my MacBook Pro in closed mode with an external display. Once the closed system was in operation I would put the MBP to sleep at night, turn off the monitor, and next day turn the monitor on, touch a key and connect to the Internet, all very smoothly.
But yesterday I rearranged my office, and closed mode has been very iffy ever since. The Internet rarely connects without my having to shut down or restart the MBP several times, and then, if I close the lid the connection cuts out. Trying to solve the problem, I’ve taken all the plugs out and reinserted them to no avail, gone through the connection start-up process from scratch, and even given the system 24 hours ‘settling down’ time in case it needed it to adjust to the new position in the room – no improvement.
This posting is written on the MBP with the display not connected. And it's fine. But the display worked with it before, so why not now? I must emphasize that it is only the Internet connection that causes problems when the display is connected - oh, and the occasional freezing of desktop files.
Any thoughts, please?

Hi Uxenden, you might want to move this post to the Macbook Pro forum; this is the Mac Pro forum. You will probably get better answers to your problem there.

Computer freezes in lid-closed mode when connected to external display

I have a Sylvania SC190 CRT display connected to my Powerbook via a VGA to DVI adapter. Every time I put the computer in lid-closed mode and try to run it off of just the SC190, after a few minutes it freezes up and I have to hard restart it(hold power button down).
Now, a few days ago, my powerbook stopped recognizing the display as an SC190, and just recognized it as a VGA Display. Don't know if this is relevant, as I have never used lid-closed mode before.
Does anyone know what the problem is, and/or what I can do about it?
Thank you.
PowerBook 15" G4 1.67 GHz Mac OS X (10.4.8) 512MB, 80GB, SD-DL

I have the exact same problem.
Here's my story:
To give you some backgroud, my setup involves having the macbook on a mstand hooked up to an external monitor. I run a usb hub from my macbook, this is where my mouse transceiver is plugged in. I use am Apple wireless bluetooth keyboard (latest slim model)
I recently purchased the 13.3' inch 2.26 MBP as I gave my older 2.0 uMB to a family member. The computer is in the stock configuration with no hardware upgrades.
I have noticed weird behaviour when waking the computer from sleep when the lid is closed. When i wake the computer up (by tuning on bt keyboard), the keyboard light blinks like there is not bt connection and the computer will wake in an inactive state. The led light will be on, but when i flip the screen up....nothing. Screen is dark, keyboard pressing does not illicit any responses. I have to do a hard reboot by holding down the power button to restart the computer. Unfortunately any previous data or work is lost.
I work in IT so I completed troubleshooting and also things outlined on forums in google. Reset PRAM, reset SMC and also reinstalled OSX. Still I get the same result. Fearing I purchased a defective unit, I called Apple and they told me i could exchange the computer so I dropped by the apple store and exchanged it quite easily.
I've spent hours restoring from time machine and I am experiencing the same issue on my new laptop. I'm now assuming its not hardware but more firmware related as I had to do a bluetooth firmaware upgrade when I bought the computer when I checked for software updates.
Is anyone else having any wake issues with their new MBPs? And what should I do next? Should I exchange for a 3rd unit? Thanks for you help everyone.

Lid closed mode--ntsc and pal

I used to be able to put my MBP's display onto a TV using lid-closed mode and the Apple DVI-video adapter. I was changing my TV's resolution to something slightly higher, clicked the wrong setting (set the display mode to PAL), and now whenever I use lid-closed mode (or when I use boot camp to boot into windows XP) my TV (NTSC) does not work. It only does this in lid closed mode, and I've reset the PRAM to try to fix it. I can't see the TV display in PAL mode, so I can't change it back to NTSC. Please help!!! Should I reset my PMU or use some EFI command?
15" MBP Mac OS X (10.4.7) using composite video on dvi-tv adapter (ntsc)

I recommend running both the MBP (lid open) and the TV at the same time in screen spanning mode (not mirror mode). In this way, you should have complete control over the TV's Display Preferences settings from the screen on the MBP. Make sure you have the "Show displays in menu bar" check box clicked in Display Preferences. You should be able to restore the old settings you were using for your TV with this technique.
Once you get your old settings restored, you can go back to using just the TV with the MBP lid closed again.

Cisco ISE 1.2, Clients not getting IP address in closed mode

Hello, I am running closed mode on my switchports. I have an issue where some clients come in in the morning, try to login, and will not get network access. I see that this is because they do not get an IP address. I am using MAB for authentication currently. They appear to MAB correctly and get Authorized in ISE, but they do not get an IP. Therefore, they also do not get the DACL of permit ANY. It's like the port gets de-authenticated during the night. Usually when the machine is rebooted it will come up with an IP address. Here is my switchport config...

Thanks, here is the requested output of an Unauthorized client. I had to configure authentication open so they could still get access...

'authentication control-direction in' in authentication CLOSED mode

Switch: 4510R+E, running a DEV version based off 3.6.0
ISE: 1.2.0.899 patch 7
Hi, I have been working on a weird issue where some of my clients would randomly drop their IP address and the only way I could get it back was to move their port to authentication open mode. I need to run in closed mode because I change VLANs via MAB.
I have been working with TAC, and they suggested I add the command 'authentication control-direction in' to my switchport config (below). With the couple tests Ive done, this seems to help. But I would like to understand why. Doesn't the control-direction command somewhat nullify the premise of running in closed mode? I.E. It allows some communication before the device is authorized. Thanks.

switchport access vlan 34
switchport mode access
switchport voice vlan 66
logging event link-status
authentication event fail action next-method
authentication event server dead action authorize vlan 34
authentication event server dead action authorize voice

end

I also needed to use this command to keep devices authenticated. It was happening with a CCTV system that was an embedded Linux OS. It was on MAB and because it wasn't transmitting any traffic (unlike a noisy windows box) then the switch wouldn't be able to reauth it as it had no mac address to be able to auth, so would show up with an 'unknown' in the MAC field.
Basically it allows traffic to flow out of the port. This enabled the device to be able to receive HTTP traffic and made it respond and then the switch could auth it again once the device sent a frame.
when you do a show authentication sessions you will notice a Oper control dir: both will change to Oper control dir: in

Using MBP in closed mode for extended periods

I use my MBP mostly in closed lid mode as a desktop computer and only use it as a notebook when I'm on the move. I was wondering, is this a bad setup considering that when the lid is closed it's covering up vents and holding heat in?

Hi,
I just installed Leopard on to my Macbook Pro (which is attached to a 19" Samsung monitor) and cannot get Spaces to work.
I was told it is possible to have Spaces work in closed mode though. I just have some concerns about keeping the MBP closed for extended periods of time, particularly when running programs that place a heavy demand on the processors (i.e. Second Life, Photoshop etc).
Is it not possible for the computer to overheat or for the screen to somehow get damaged with the top closed ?
I really want to use Spaces but it does not appear to work with dual screen set ups.

Closed Mode?

A new 2.16 GHz Core Duo has just came into my hands, but I'm not sure what its limitations are, given the problems many of these units have had shedding heat.
I currently use a PowerBook G4 on my office desk with the lid closed and keyboard, mouse and monitor externally attached. Is this advisable with the MacBook Pro?
Any thoughts or experiences would be appreciated!

Yes it's fine to use in 'lid closed' mode:

Will Logitech Wireless keyboard/mouse work in lid closed mode?

I know you are supposed to plug in a USB keyboard and mouse to get the MacBook to work in lid closed mode.
Is it a strict requirement to be USB wired? Or will the Logitech wireless desktop be sufficient (with radio dongle plugged into USB)?
Thanks.
iMac Core Duo 2.0 Ghz Mac OS X (10.4.7)

I honestly do not have a lot of confidence in this working.
Unless you can find someone who's done it or somehow get an answer from Logitech (good luck with that one) I don't know how you're gonna find out, short of buying the combo and returning it if it doesn't work.
Applecare is willing to help things work properly when they should, but something like this isn't gonna get you any response or help over the phone other then a reference back to these forums or to Logitech/google.
Hope you find an answer, but all i know is that if it says USB...then there must be a reason. Doesn't mean nothing else will work though, but might not be the easiest thing to get an "in advance" response on.

Resuming sleep from lid-closed mode?

Sorry if this has already been answered, but searching through the manual and 34 pages of previous posts didn't turn up anything.
When I get to work, I connect my MBP (in sleep mode) to my external monitor and then to my usb keyboard/mouse, which triggers the computer to wake up and go into lid-closed mode. I work all day with the lid closed.
The problem is that when I'm ready to leave at the end of the day, I cannot just disconnect everything and resume sleep mode for the transport home.
If I go to Apple/Sleep, it'll go to sleep for 1-2 sec, then re-enter lid-closed mode. If I unplug everything, then the computer stays in lid-closed mode and won't go to sleep. The only way to get it back into sleep mode is to disconnect everything and open up the lid, wait for the display to come on, then close it again. Time consuming measures like this clash severely with my impatience at getting out of the office.
Any tips on how to re-sleep from lid-closed mode without having to open the lid? Thanks in advance.

My impatience was my own undoing. Upon further testing, once the magsafe is disconnected, the laptop begins the routine to go to sleep. I'm a very happy camper now...don't have to open the laptop at all, and I get to reduce the rate of dimming of my laptop screen.

Bezel separating? / lid closed mode

I've been operating my MacBook in lid closed mode for a week now. This morning I noticed that the plastic bezel on the left side and at the bottom of the display are starting to display small gaps with the LCD. Is this something I should be concerned with? Thanks.
MacBook Mac OS X (10.4.7)

This is my question too, so to save a new thread I'll chime in here.
When I used an ibook, extensive googling yielded the concensus that the ibook should definitely not be run with the lid closed as the machine is ventilated through (or partly through?) the keyboard. In contrast it was said that lid closed mode was fine for the powerbook which was ventilated through the case somewhere.
As far as I can tell the ibook and macbook have pretty similar cases, including what I assume is a vent at the back. (Actually on the ibook it looks more obviously like a vent, as it has a grill.) I don't have access to a powerbook to compare.
So I guess that still leaves me asking whether it can be confirmed that the macbook is definitely safe running with lid closed (which is how I've been using it). Is the rear vent on the macbook more efficient than on the ibook? Or is the thing on the back of the ibook not actually a vent at all? ???
Can anyone shed any light?

MacBook Pro, Lid-Closed Mode

Hello, I'm considering getting an Apple Cinema Display to use with my MacBook Pro. I understand that most modern MacBooks, including the Pro are lid-closed mode compatible.
A) I understand that one must have the display, keyboard, and mouse to use the notebook in lid-closed mode. Is it true that the Apple Wireless mice and keyboards are compliant as well? If I've read this article correctly, then yes:
http://support.apple.com/kb/HT1308?viewlocale=en_US
B) The screen doesn't turn on, back inside the notebook does it? That would be a redundant use of power.
C) Is lid-closed mode harmful to the longevity or otherwise well-being of my MacBook Pro?

Is it true that the Apple Wireless mice and keyboards are compliant as well?
Yes.
Is lid-closed mode harmful to the longevity or otherwise well-being of my MacBook Pro?

MBP in closed clamshell (display closed) mode with an external display

I want to use my Macbook Pro Unibody in closed clamshell (display closed) mode with an external display
And I want to know if, the heat will damage the lcd of m macbookpro.
I want to buy a holder
http://twelvesouth.com/products/bookarc/
but i still have doubts about it the temperature and the Screen.
Thanks..

Apple says closed clamshell mode is a valid way to operate a Mac notebook, so that should be assurance enough. I don't know where the notion comes from that non-operating LCD screens can be damaged by heat. It would take a lot of heat to do damage. Way more than can be supplied by the computer itself.

Problem with lid closed mode

So as far as i know, to get the computer to run in lid closed mode you press f7 until you get video mirroring, the second mode i believe, close the display, then wake the computer with the external mouse or keyboard. I've done this, but almost as soon as i wake the computer, it goes back to sleep again.
How do i fix this??
Is it a problem for I'm using a windows keyboard, but i wouldn't think that could be it.

Also, if you haven't already done this, make sure that Bluetooth is enabled and that you "Allow Bluetooth devices to wake this computer" (Systpref/Bluetooth/Settings)

MBP in lid closed mode, will the display get to hot?

i run my MBP in lid closed mode all of the time, as i have a Cinema Display hooked up. i'm not too worried about the MBP overheating, but i was wondering about the display getting extra hot from the MBP when it's closed. i do have a radtech microfibre cloth on top of the keys as protection...
should i be concerned?
17" MacBook Pro Mac OS X (10.4.8)

I'm interested in this issue too, as I intend to get an MBP but use it with an external screen and keyboard most of the time.
I'd also like to know about ventilation - where does the cooling air come from and go to? What parts need to be kept clear, and which bits can I have up against or close to a bookshelf or hutch or whatever?
Thanks in advance.
PS, I think the glossy screens look fantastic, but also think I'll go for matte since they are more practical.

Possible to disable closed clamshell (display closed) mode?

I would like to disable the closed clamshell (display closed) mode on my MBP, where you can run the computer with its lid closed if it's attached to an external monitor. I don't ever do this (I use the MBP screen as a second monitor), and this option causes my computer to randomly wake up if I turn off/on my office lights, or accidentally press a button on my usb keyboard or mouse.
I know there is no option to turn this off in the System Preferences, but is there a terminal hack that can do this?
Thanks!

If I understand you correctly, you don't close your display (because you use it as a second monitor) and sometimes you put the machine to sleep with its display open. But turning your office lights on or off wakes the computer from sleep (which certainly indicates an electrical problem in the office wiring or lighting, and one that can't be good for your computer). And of course hitting any key on the keyboard wakes the computer too, exactly as it's supposed to do. If I understand all this correctly, what if anything does it have to do with clamshell mode, and what particular aspect(s) of clamshell mode do you think you need to disable, and why?
While you're thinking that over, I recommend connecting your computer's AC adapter to a high-quality surge protector or an uninterruptible power supply that features power filtering.
