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:

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?

How do I use my macbook pro lid closed

How do I use my macbook pro lid closed?

Well what i'm trying to do is keep file sharing on while macBook is closed so i can access files through "newtwok" (Back to my mac) with my imac...
Ideally i would then control my macBook with screen sharing on my imac while the MacBook is stored behind my iMac...
Somehow it worked before but now it stopped...and everytime i close the lid ..mac book pro goes black screen and completly disconnects from the newtwork...
Everything works fine with lid open..
I am trying to do this because i have a new imac with thunderbold and an older macbook pro with mini display port..and as you might already know...you canot connect these thow devices using thunderbolt cable...which really *****....there is also no adaport enabling this...and i really dont need to buy another mac book that just has one more hole in it >.<
Anyway..hope there is a solution somewhere to keep file sharing going while lid down..
regards remo

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?

How can I prevent that emails are downloaded (POP3) when the lid of my MacBook Pro is closed?

Disable Power Nap in the Energy Saver pane of System Preferences. Uncheck the box marked Enable Power Nap... in each of the tabs.

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.

Simulate lid closed mode

Do you know if is possible to use a software utility to simulate the lid closed mode for use with external display?
I would like to use my macbook pro only with external display without close the lid, is possible?
Thanks

I have two suggestions:
- If you close the lid and then wake up the Mac with a USB device like a mouse or a USB flash memory drive or some other USB device, then only the external screen will be active. Once the external screen comes on, you can open the lid and the internal screen will remain off. You have to have the MBP power adapter plugged in for this to work.
- You can also use a small magnet to simulate a closed lid. Just place the magnet on the right edge of the plam rest over the area that is above the security port on the right side. This will make the MBP think the lid is closed.

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.

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.

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.

What is the cracking sound when I open my MacBook Pro lid?

When opening and closing MacBook Pro lid, it makes a cracking sound. Does anyone have an idea what it could be? It's not the hard drive because Geek Squad ran a test and everything passed.

Try this: Loosen the screws in the rear of the MBP (by the hinge) and re-torque them. See if that will alleviate the problem. You will need a 00 Philips driver.
Ciao.

MacBook Pro lid

My three year old MacBook Pro lid has stopped locking when closed. Having to clamp it down with a book. Any advice please?

Take your MBP to your local Apple Store or AASP. Let them fix it.

Hi - How do I connect an HDTV as a second monitor to Thunderbolt display with macbook pro in clamshell mode?

I have a Late 2011 Macbook Pro in clamshell mode connected to a Thunderbolt Display with the built in Thunderbolt cable. I want to then connect an HDTV via the Thunderbolt port at the back of the Thunderbolt display. I already had a cable that I thought would work which turns out to be a MiniDisplay port to HDMI cable and therefore not compatible with Thunderbolt to Thunderbolt (Mini DisplayPort not being the same technology although it uses the same port - although I'm not an expert !!) So far a web search has provided me with the only solution being using a Thunderbolt dock or storage that has multiple Thunderbolt ports and then using that to daisychain inbetween the Thunderbolt Diplay and the HDTV. The cheapest solution I can find for this would be about £250. Surely not ??!!!!
Many thanks for any comments - Nik

You could also use aThunderbolt dock with HDMI, such as:

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?

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.

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.

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)

Can the cover on the macbook pro be closed while playing music?

can the cover on the macbook pro be closed while playing music?

Air is drawn in through the keyboard for cooling, so I would recommend leaving it open 1/2-1" so the air can move.
