Can the computer sleep while encoding?

I am currently in the process of making a DVD from iMovie using iDVD. While I knew it would take a long time to go through all the encoding, I didn't count on it lasting this long.
I have to pack up the computer and take it home, possibly before it finishes the process. My quesiton is this, can I close the lid on the computer while it is still encoding without having to start over? Can it sleep and pick back up where it left off, or better yet, can I change settings so it won't go to sleep when I close the lid? It has been going for about three hours now, I would really hate to have do it all over again.
Second question: I have made DVD's using iDVD before, and although they have been about the same length (actually with many more effects than this one), none of them has taken this long to encode. We have been sitting in the "encoding audio" phase for nearly all of the time this go 'round. I hear this is not uncommon, but how will I know if iDVD has frozen?
Thanks for any suggestions, I have about an hour before I have to close the lid....
Bryan

Len,
Something you do for while you're on the boat picking up your DVD-Rs?
You got it!
.... or almost. I shoot underwater video and on the boatride home I sometimes have a lot of time (1.5-2 hrs). So one day I decided to try my luck - and it worked.
OK, that's the last time.
Man, I sure hope so ....
I knew I should never have written that comment .... LOL.
Actually, I'm quite amazed that closing the lid would return you to the process...and finish successfully.
Have to add here: I only tried this when creating a disk image. But it always worked.
mish
PS: I'm sitting on the boat while writing this .... Now THAT'S what I call Airport EXTREME!

Should I let the Powerbook sleep while it is encoding in iDVD?

Should I let my Powerbook sleep when I'm burning a DVD or discimage? Will letting the Powerbook sleep interrupt the encoding process? Thanks, Janice

Hello, Janice,
Welcome to the discussions!
I would have answered, NO, keep your Powerbook on and don't let it sleep, but then I did a search for you and found the thread below. You could have found this thread by doing a search in iDVD discussion with the terms 'encode' and 'sleep' (That is how I found it!). You will find as you use the discussion forums that many times your question has been addressed, or you will find some similar questions, and you will definitely find out new information.
So, have a look at this thread. There are conflicting opinions here, but I would go with Len Goff's suggestions as he is very knowledgeable:

We have a 2.66 GHz IntelCore2Duo iMac; OS X 10.6.8. This morning the computer crashed while my daughter was working on a document. When she restarted it, all .rtf files start with "Applications/ical.app/" and some other garbled text. Not sure how to fix

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If that doesn't help Reinstall the OS.

"wait 20" goes 23 minutes when the computer sleeps for 3

I have a script that is supposed to perform a certain function after 20 minutes. When I leave the computer and it goes to sleep, the script pauses until wakeup.
Can anyone think of a way for it to adjust the wait time after wakeup or to take into account the sleep time? Any ideas might help.

Sorry, I thought of a better way to handle this I think. I'll ask it in another topic.

Computer Sleeps While Syncing Photos

Hi Guys,
iPhone 3GS current software
iTunes Current software
Windows 7 64bit current updates
My computer is set to NEVER sleep regardless of battery power or plugged in. If I select a folder to sync that is around 400+ images, once I hit the sync button iTunes will begin transferring and converting the images but will ALWAYS cause the computer to sleep while in the middle of the sync... really it seems that something at the end of the sync process is causing this. It does this regardless if I am activly working on the computer.
If I select a folder with less images this does not happen.
Thanks for any help or ideas
Cheers

Jake, did you find any solution? I'm having exactly the same problem, though I just upgraded to OSX 10.8.2. I have basically all the same settings as you have. In fact I did try unchecking the "put hard disk to sleep whenever possible" for a while, but didn't help. Still goes to sleep after about 1 hour of otherwise inactivity (i.e only itunes playing). This has got to be a bug, and seems to be affecting a lot of people. I'll keep an eye on this topic.
Thanks.

Computer sleeps while iTunes is playing

Just like the title says, my Mac goes to sleep even when iTunes is playing. This is pretty ludicrous. Is there anyway to prevent this other than changing my power savings settings to never let my Mac go to sleep? I don't want to do that, I want my computer to go to sleep when I am not using it.
This sure seems like a bug. I am running the newest version of iTunes as well as Lion. Thanks for all your help.
My current energy saver settings are:
Computer Sleep: 15 min
Display Sleep: 15 min
Put hard disks to sleep when possible - yes
wake for network access - yes
allow power button to put the computer to sleep - yes
start up automatically after a power failure - no
restart automaticall if the computer freezes - no
Again, I would rather not have to change these settings in order to keep iTunes playing. Is this a bug or am I doing something wrong?
Thanks,
Jake

Recover folders after the computer froze while moving them

Hello,
while moving files from one drive to another my imac mid 2011 froze and had to be restarted. Unfortunately, all of the folders now can't be accessed. I can see them in grey in the destination drive, the size is the right one but I have no way to get inside the folder. I guess it must be in a cache somewhere. The folders are not longer in the origin drive.
Is there a way to recover them ?
Thank you

ok well for anyone who has the same problem, we left it plugged in, and restarted the computer, and the iPod is fine.

Time Machine crashes every time after the computer sleeps or goes into screen saver for a period of time

Time Machine works for me about 90% of the time, until I leave the computer alone for over a hour it seems and gets into the late screen saver stage or goes to sleep. After it does this Time Machine will not work, yet the hard drive is still fully fuctional. Please Advise.

Loss of Airport / Airtunes when the computer 'sleeps'...??

Does anyone know why when I the computer wakes up after i put it to 'sleep' it cannot find the Airtunes base station. It knows my 'Airport Network' but cannot find the white thing in the wall socket!!??????
G4 iBook 800Mhz (old skool) Mac OS X (10.3.9)

Yea I had thought it may be that!
The antenna obviously works fine as it does get signal when the lid is nearly closed!

Connecting to a flatscreen - can the computer be closed?

Hi,
I frequently watch movies on my macbook connected to my flatscreen via miniDVI to vga. I usually leave the screen open but I just upgraded to a bigger TV and would like to keep the screen closed to save space. Is this possible? Do I need snow leopard?

Yes. Wake it up with an external keyboard and mouse; if using Bluetooth, they need to be paired with the computer first. Click here for more information.

With lion the windows reopen after the computer sleeps. How do you turn this feature off?

Is there away to turn off the reopen windows feature

It is one of the over 250 new features of the World's Most Advanced Operating System called Resume.
When choosing Restart, Sleep or Shutdown there is a checkbox you can uncheck to prevent the apps from launching.
Also in System Preferences > General there is a hard-to-find checkbox under "Number of recent items" you can turn off.
If you want to turn it off on a per app basis, (TextEdit is by example, replace TextEdit with the name of the app)
Launch Terminal and copy/paste this at the prompt...
defaults write com.apple.TextEdit NSQuitAlwaysKeepsWindows -bool false
Press return.
To turn off Resume globally...
chflags uchg ~/Library/"Saved Application State"
Press return
The reverse of the first one is to replace false with true.
The reverse of the second one is
chflags nouchg ~/Library/"Saved Application State"

27' imac is slow to navigate and download from the net, and the computer freezes while on the net, what could be causing this issue?

can anybody answer this question

Johnso,
Please complete your profile so we at least know a little more about your system, Apple has made quite a few 27" iMac models using different versions of OS X so it would be helpful to us if we knew the model you had and the version of OS X installed.
PLEASE complete your profile, you can find it under Your Stuff and Profile in the upper right of this page.

Will an Apple Iphone 3g charge from a Powered USB Hub while the computer is

Hello,
Will an Apple Iphone 3g charge from a Powered USB Hub while the computer is sleeping?
I have a Motorola SLVR L7, two BCK-08 Bluetooth Stereo Headsets and two iPower Secondary iPhone batteries that all charge from my Powered USB Hub while my main computer is sleeping.
It would seem that my iPhone 3g will not charge from a Powered USB Hub while the computer attached to it is sleeping?
Is there any way to get an Iphone 3g to charge from a PoWeReD UsB HuB while the computer it is attached to is sleeping?
I'm thinking in terms of greening things ... but this is making me leave a 170 Watt computer running while I sleep ... I don't use the computer much while asleep ...
Thanks for your time,
Bobby

How 'linux' is OS X?
In linux you can get a lot of USB information by typing "+lsusb -v+"
or through "/proc/bus/usb/devices"
(but they would both list everything connected via USB)
if you knew the vendor and device id you could type as an example
+(laptop:/proc/bus/usb) # lsusb -v -d 050d:805c+
+Bus 001 Device 008: ID 050d:805c Belkin Components+
+Device Descriptor:+
+idVendor 0x050d Belkin Components+
+idProduct 0x805c+
+bcdDevice 0.01+
+iManufacturer 1 Ralink+
+iProduct 2 802.11 n WLAN+
or
/proc/bus/usb/devices
+T: Bus=01 Lev=02 Prnt=03 Port=02 Cnt=01 Dev#= 8 Spd=480 MxCh= 0+
+D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1+
+P: Vendor=050d ProdID=805c Rev= 0.01+
+S: Manufacturer=Ralink+
+S: Product=802.11 n WLAN+
+C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr= 4mA+
In windows under details it lists the parent ID (port above) so if you found the USB port the iPhone was connected to ... you could find the hardware and vendor id or name of the hub it was plugged in to ...
I'm thinking it might be easier and more positive to start a thread requesting that anyone who has an iPhone that will charge from their computer through a USB Hub while that computer is sleeping ... but I don't know if I can start a thread with a title that long ...
