Closed-lid mode USB devices disconnect randomly

I just recently connected my MacBook Pro to my Samsung DLP HDTV and started running it in closed-lid mode so my TV is the primary/only display. I also have an external hard drive (USB), external mouse (wireless with USB toggle) and the new Apple bluetooth keyboard.
The problem I have isn't entering the closed-lid mode. But once in closed-lid mode (after a short period of time) all of my USB devices disconnect and then reconnect. I know this because I get an error saying that my hard drive was removed improperly (please eject before disconnecting, etc) and I also get a message from my mouse software saying that my mouse has been disconnected. But then they reconnect themselves (hard drive shows up again on desktop and mouse software informs me that the mouse is present again).
Has anyone had this problem before where USB devices disconnect in the closed-lid mode? I just upgraded to Leopard (formatted the drive and started from scratch). I never tried this within Tiger so I don't have that for a reference. This is really annoying because I have my entire music collection on the external hard drive and it just stops playing when this happens and I have to restore the path to my music collection within iTunes' preferences (it defaults back to ~/Music/iTunes/ when it figures out that the hard drive is no longer there).
The strange thing about this is that when I don't run in closed-lid mode this never happens. I'll be more than happy to provide more details if needed. I greatly appreciate your help.
Thanks!
Mike

i appear to have the same problem under Vista (via Bootcamp) on MBP (2007). i close the lid, and 5-20min later i hear the sound a USB device makes when it disconnects, and a minute or 5 later it reconnects. i don't actually have any USB devices plugged in, but there are several components in the MBP that are connected internally via USB (DVD drive, etc).
what's almost as annoying is that the LCD backlight will come back on of its own accord, even though the MBP's been idle for more than the LCD/backlight time-out period. after the next idle timeout it turns off, only to turn back on againa while later. i see this under OSX & Vista.

  • IChat and Closed-Lid Mode

    I found something very interesting in iChat 4.0.8 and Leopard 10.5.7. I run my MBP in closed-lid mode with an external Apple Cinema Display. When in iChat, I cannot do audio chats at all - i.e. no sound input with either of my external interfaces (Apogee Duet via FireWire and Mbox 2 Mini via USB). Of course video doesn't work at all, as the built-in iSight is not accessible. If I open the MBP display, they both work normally. As soon as I close the display, wake the MBP and run in closed-lid mode, I cannot get any input whatsoever. The devices work normally in QuickTime Player Pro, Soundtrack Pro, Logic Pro, Pro Tools, etc. In either mode there IS an input level in System Preferences > Sound as well. I even tried to "trick" the system by using Audio Hijack Pro and Soundflower, but the issue remains. No combo of settings in the Sound preference pane and iChat preferences will allow a signal input.
    Anyone else running a MacBook or MacBook Pro in closed-lid mode? Does this issue happen on your Mac as well?
    VERY strange,

    Well...Snow Leopard seems to have fixed this issue.

  • DVI to VGA Adapter Closed Lid Mode Distorted Picture on TV

    Hi
    I managed to hook up the DVI to VGA adapter and view on my Sanyo TV. Nothing fancy just a older TV.
    I am feeding through the Yellow Video output into the video input on the TV. (Also tried s-video)
    Viewing with the macbook lid open no problems. Remembered that I could close the lid.
    Followed the instructions online about connecting, closing the lid and waking up using my bluetooth mouse.
    First time things went well - able to use Front Row and View Slideshows etc. also steaming video from Safari, (TV Land for my kid)
    Then the screen began to flash - and change to black with rolling images.
    Like you used to have in the 60-70's black and white TV - multiple images rolling past over and over.
    I tried rebooting - starting new connections, using different cables, using both VGA and S-Video directly into the TV and not through my reciever.
    Any ideas!
    I can't use closed lid mode at all. I must instead, dim my screen.
    Help?
    Thanks
    Buddy

    Thanks, BSteely, I have the latest QT and iTunes already. Closing the lid seems to kick the MacBook external display into some special mode that Front Row can't display videos in. For example, you get the Front Row interface, but as you select movies/TV shows, the preview window on the left side is blank. Open the cover, and have both displays going, and you can see the previews fine (and of course, you can see the movies/TV shows play fine as well when you click on them)
    Running Quicktime Player full screen works fine without Front Row in either open or closed lid mode. So it is apparently something wrong with Front Row itself.

  • TV + Closed-Lid Mode?

    Is running in closed-lid mode on the MacBook using a television with the Apple Video Adapter supported? I can't get it to work properly.
    Brian

    Make sure your power saving settings aren't unusual - I find normal works fine. Configure your external displays with the lid open and then with the power cable connected try closing the lid. It will fall asleep immediately - let it. Then when the light throbs try waking it back up again with the remote... It works for me, but it did try my patience before I came up with a routine that I was happy with.
    Also - how do you connect your TV? My TV has a monitor / DVI out and it's quite happy with that. I shouldn't think that S-Video should be too different. Has anyone tried with S-Video? Hope this helps...

  • EXTERNAL HDD NOW DISAPPEARS WHEN USING MY MBP IN CLOSED LID MODE

    I have an 15" MBP 2.53 running Snow Leopard, which installed fine. When I go to use it with my Apple 24" Display and my external hard drive, the external HDD disappears when I go into closed lid mode.
    The finder freezes too, and I can no longer enter into Time Machine.
    The external HDD does show up in disk utility, however.

    and please ... STOP SHOUTING!
    It doesn't make your message any more relevant or increase the motivation to help you. To be honest, it makes you look like a moron, if anything.

  • MacBook Pro keeps going to sleep in closed-lid mode and external monitor

    I am trying to run the MacBook in closed lid mode with an external monitor. It seems to work fine at first, but after about 10 seconds, it goes to sleep. I can wake it back up but it just goes to sleep again.
    Has anyone seen this before?

    I figured it out. Apparently you can't run in closed-lid mode on battery. I plugged in the power adapter and it's working fine now.

  • Turning off closed lid mode

    I was wondering if there was a way to turn off the closed lid mode feature. It's the feature that allows you to use your MacBook even when the display is closed by hooking it up to an external monitor, keyboard and mouse. The problem I'm having is that when I close my MacBook to go into sleep mode, I leave my wireless mouse dongle plugged in, when my mouse gets a slight bump the computer awakes from sleep mode and goes into closed lid mode, it's really really annoying. Help please!

    This is what you want.

  • Can closed lid mode damage new MacBook display?

    I would like to buy one of these new 24" LED Cinema Displays to use it with my new (late 2008) MacBook. Actually I would love to mount the display on my wall in order to use it at a TV with the MacBook (if longer cables are available).
    Apple advertises to use the new MacBook in closed lid mode with the build in iSight. Now I heard at my local dealer, that the MacBooks heating can seriously damage the internal display when the lid is closed.
    I allways thought that these two devicews are made for eachother. Do I risk to damage my MacBook when using as a video or TV source for several hours? Do I loose warranty?

    Thank you Malcom. I read these articles. They describe how you enter the clamshell (or closed display) mode. But I still feel that they don´t not really cover my question: Can extensive use of the Macbook in clamshell mode damage the internal display (for example while watching movies on the connected 24" LED Cinema Display)?
    It is just because this guy at the Apple dealer over here (GRAVIS) said something like: "oh - this is the worst thing you could do to your MacBook ..." and: "everybody is saying that ..." and so on.
    Has Apple taken specific care of ventilation in clamshell mode on the new unibody MacBooks? Does the heat then flow out of the rear of the machine or is the MacBooks glass display somehow less sensitive for heat?
    Thanks again.

  • Closed Lid Mode in Boot Camp...

    Hey guys.
    Before I go and splurge on a 24" external display...will it be possible to use something like closed lid mode under boot camp?
    Will also want to be able to use a bluetooth mouse and keyboard
    cheers

    Hi V.K., I followed the reset steps for PRAM and the problem still exist. Could this be the battery's problem? BTW, my laptop is still fairly new, got it in December.
    Thanks for your help

  • External display and "clam shell" closed lid mode = "Input Not Supported"

    I have an Acer AL2016W 20" monitor hooked up to my again Powerbook due to it having a cracked screen. It is working just fine right now, in 1680x1050, when the screen is open. Citing this article,
    http://support.apple.com/kb/HT3131
    I should be able to close it and have it working as well. When I do close it then wake it, I just get a "Input Not Supported" message on the monitor. Any help?

    I'm still puzzled at why it the screen is activated when the lid is closed and woken with an external USB device
    That's rather puzzling as the display should not work if the lid is closed. If you have an external drive you're able to install a clean copy of Mac OS X to and boot from you can see if the issue persist there. If it does then it's most likely a hardware issue and you should contact AppleCare. If it doesn't then it has something to do with either your software installation else some utility you've installed.

  • Closed-lid mode on the MacBook Pro

    *My situation:*
    My 17" MacBook Pro is connected to an external 24" display using DVI to DVI.
    What I want to do: I want to be able to close the MacBook Pro lid to put the computer to sleep (along with the external display). I should be able to click a mouse button or keyboard key that is connected via USB to wake the computer up but only show video on the external display; the MacBook Pro's built-in display should not be activated. (This information can be found here: http://docs.info.apple.com/article.html?artnum=86286).
    What I used to be able to do: exactly this, using my old 13.3" MacBook.
    What the problem is: the computer and display successfully go to sleep, but upon pressing a button on the mouse the MacBook Pro is fully activated including its internal display, as well as the external display.
    What I have tried: multiple USB keyboards/mice and the undocumented method of simply inserting or removing a USB device to wake the system. I have also tried with an Apple Remote and tried to invoke sleep within the Apple menu instead of closing the lid; every time the computer wakes completely.
    The power is connected.
    Any ideas guys?

  • IDEAPAD V460 - USB port disconnects randomly

    Hi Community,
    I am in a trouble with my IDEAPAD V460, 59 - 044185 (4th one from the beginning) which I purchased around a couple of years back. It was working fine without this annoying issue until recently. This partiular model comes with three USB ports, two on the left side, one on the right side.Since around last 15-20 days, any device plugged into any one of the two USB ports on the left hand side of the laptop is getting disconnected randomly. I use an iBall 4*1 USB hub to connect one keybaord, one mouse and one modem to any one of the USB ports on the left side. Initially I thought it to be a software issue. But reinstalling the OS or even switching over to other OS did not solve the issue. To probe more, I refrained from using the hub and connected two of the mentioned devices directly to the left side ports. Still, the problem persists, but the frequency of disconnection is less. Sometimes, the devices gets reconnected, sometimes do not. That is also in a random fashion.
    One of my friend having a Y500 model also having similar issue. As you can understand, given the number of USB devices we use everyday, it's hampering my day-to-day activity.
    Two years being passed, I am out of warranty. I found that there are so many people around here also having same or similar issues. Presently, my perception is that those to USB are not being able to pull out enough power to maintain +5V and causing this random disconnect. Any idea what to do?

  • All iOS devices disconnecting randomly from D-Link router

    Hi,
    All my Apple devices disconnect every 10 to 15 minutes from my D-Link DIR-615 router. My Apple TV, 2 iPhones and my iPad always lose the connection. Can't stream anything on my Apple TV, I have to reset the router every 10 minutes. This happens only on Apple/iOS devices. My 3 PCs and my Samsung Galayx device don't have these problems, never disconnect and can stream for hours with no problems.
    All my Apple devices are up to date. My router has the latest firmware. I have tried to change the channel and channel width to different settings with no luck.
    Any idea on how to solve the problem? Changing my router to an Apple AirPort is not an option. The fact that only Apple devices are concerned is certainly not an accident.
    Thanks in advance!

    Settings > General > Reset > Reset Network Settings
    Restore the router to default settings and reconfigure.

  • Bluetooth Device Not Waking Up Laptop in Closed Lid Mode

    Anyone have any ideas on how to solve this issue. my keyboard and mouse will wake up the laptop but for only 1 or 2 seconds and it goes right back to asleep. I have my prefs set to never go to sleep but it still goes to sleep...
    thanks

    it looks like i've solved my own problem, indirectly though. Usually i would start up my laptop and login then close the lid. it would never wake up and stay up.
    something told me to turn it off and back on. but this time, as soon as i turn it on and close the lid immediately, before the login screen appears. it stays awake even if i open the lid, the laptop screen doesn't wake up, it's totally black. it act like it's sleep but it's technically not
    if any of you mac users out there have the same problem i was having just give this a try. to wake up your laptop again, first put the system to sleep on the external moniter, second unplug your minidvi cable, third open your laptop lid.
    Walah! problem solved.
