When to turn sleep, turn off, etc.?

This question has probably already been asked, but at what points (in terms of time not in use) is it worth putting the MacBook to sleep? Turning it off? What's best for the battery? The hardware? (For instance, if you're going to be away from the computer for 6 hours, is it better to put it to sleep or turn it off? If you'll be away for 1/2 an hour, is it better to put it to sleep, or leave it on with the screen saver?)
Thanks.

On a full charge and put to sleep the MacBook's battery will last more than 10 days but less than 20. I know this because I forgot to turn my MacBook off before leaving for vacation this summer. I returned 20 days later and found that the computer needed to be plugged in before it would start so I know it won't last 20 full days. Over the winter holiday I intentionally put it to sleep before leaving and 10 days later when I returned it woke up showing under 1/2 a charge left. What I don't know is whether the computer's battery will be depleted on day 11 or in the middle of day 20 or somewhere between! Well, actually I do assume it is close to the 20 day mark than the 11 day mark.
So when should you sleep it as opposed to turning it off? I generally turn it off (when I remember) if I'll be leaving it for more than a week. This has been my habit since buying my first PowerBook back around 1991.

Welcome to Apple Support Communities
Hold Sleep and Home buttons for 10 seconds until the device restarts, so you will be able to use the iPad again.
It will try to make a backup every time your iPad is plugged to the charger and connected to a network. To prevent that this message appears soon, open Settings > iCloud > Storage & Backup, and choose Backup Now

Any Way To Turn Sleep Mode Off?

Is there a way to prevent the iBook from going to sleep when the lid is closed? This can be done in WinXP but not sure about a Mac. I'd like to play a DVD on the iBook and pipe the image through my TV. I would also like to be able to close the lid of the iBook and have the DVD keep playing. Right now if I close the lid the iBook obviously goes to sleep and thus the DVD stops playing. Thanks!

i was told on here that there is a way, but it would possibly void the warrenty and may overheat the laptop...
honestly though, i rather close my laptop and be able to play music/download things then keep the lip open and risk damaging the monitor...
i'm going to call apple tomorrow and see what could be done about this

Airport Card turned off when resuming from sleep - New since 10.6.6

I use safe sleep regularly, as I use my laptop at both work and home. Ever since the update to 10.6.6 though, I have had to manually turn my Airport connection back on after resuming from sleep.
Previously, although it was unreliable about connecting to a preferred network (an unrelated, but equally frustrating issue*) at least it would remain on. Now I've had to add the icon to my Menu bar just so I don't have to dig into System Preferences every single time I reawaken my laptop.
Does anyone know why this is happening, and if there is anything I can do to prevent it? I apologize if this has been asked before, but when I searched I was unable to find anything.
*This issue is unrelated and not the focus of my post, but if you happen to know about it I would absolutely appreciate your input.
When resuming from sleep, despite being between 5-20 feet from my preferred router I will often receive a dialog asking me to select from a list of SSIDs and enter a password even though that information is already saved. Then, once I complete this information Airport doesn't actually connect and the only way to resolve the issue is to turn Airport off and then back on. After this, it will automatically connect with no problems and remain connected until I put the computer into Sleep mode again.

Maybe check in your keychain and verify the password saved is correct for your wireless router?
Do you broadcast the network name?
Could you describe "unreliable about connecting to a preferred network"?
Is "use secure virtual memory" checked in the Security preference pane? If so try unchecking that maybe? If it's a hibernation issue sometimes that could cause weirdness.

When waking from "sleep" screen turns grey under the pointer and the computer is effectively dead. Have to hold power 'off' for five seconds to regain computer.

When waking from "sleep" the screen appears normal but, the pointer leaves a trail of grey as it moves and the whole screen will turn grey if I keep moving the pointer. The computer is effectively dead. Have to shut down by using power off for six seconds and then re-starting. I know little about computers!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode.)

Every time I turn the computer off or put it in sleep mode... when I come back my wallpaper is gone. I have to keep going to my pics and getting it back. Does anyone know why this keeps happening??

Are you choosing it from one of these folders (in my screenshot) or you can also put that picture into the correct folder. The path is:
HD > Library > Desktop Pictures
If you add it to the folder manually, please restart your computer.
And yes, letting it sleep is a good idea, or else the startup disk will spin and the screen may suffer from image persistence if you leave a window or image parked in the same spot too long, so the screensave is a good idea.

At the end of the day when I turn my computer off I lose the download of firefox 3.6 and have to download again, but if I put it to sleep I don't lose 3.6.

When ever I put my computer to sleep after downloading version 3.6 I retain the update, but if I turn my computer off at night I lose version 3.6 and then I need to download 3.6 again.

Did you install Firefox correctly?

When I click sleep, Imac turns off not just sleep. Any fix?

Hi Hank,
Some things to try...
Have you done a PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.
Intel-based Macs: Resetting the System Management Controller (SMC)...
http://support.apple.com/kb/HT3964
(SMC reset= Shut down, disconnect power cord for 10 seconds, reconnect power cord, wait 5 more seconds, turn computer back on)
but it is slightly different: (PMU REST = Shut computer down, disconnect power cord for 10+ seconds, reconnect power cord WHILE SIMULTANEOOUSLY PRESSING POWER BUTTON, let off power button for a few seconds, then press power button again to restart the mac mini.)
Can also be caused by USB or Firewire devices.

My ipad (64g wifi 3g) just turned its self off and when i finally got it back on it was just on the apple start up screen with the little thing spinning beneath it. Can an anyone help!!!!!!!!!

if anyone has ether had this happen to them can u tell me and if you no how to fix it please tell

Recovery Mode is how to start all over again on your iPad like new. It erases everything, even the operating system, and reloads directly from Apple. Once that is done, if you have performed a backup of your iPad in the past, you will be able to restore all of your configuration settings and preferences after the reload occurs.
To prepare for a recovery mode restore, have the following ready:
- Your computer (plugged in to power) ready with iTunes up and running
- Your iPad synch cable plugged into your computer but NOT your iPad
- Make sure your iPad is at least at 20% battery, preferably higher
NOTE: Do NOT touch the iPad once recovery begins. Make sure your computer doesn't suspend, sleep, or shut down while the process is going on.
Steps:
- Sitting next to your computer, take your iPad (which should NOT be connected to your PC) and hold down the sleep button (on the top of the iPad) and the home button (front of the iPad) at the same time
- After about 10-15 seconds, the unit will power off (do not do anything when the "slide to power off" screen appears, just keep holding the buttons)
- When the iPad turns back on, you will see the silver Apple appear on the screen. Continue holding down the home button but release the sleep button and immediatly plug the iPad into your computer running iTunes
- You should see a symbol appear on the iPad with a picture of a USB cable with an arrow pointing to the iTunes logo. iTunes will then say that it detected an iPad in recovery mode.
- Let iTunes restore the device. It will download a fresh copy of firmware, install it, and verify the SW.
NOTE: This may take a while. iTunes needs to download about 500MB from the Apple server, then it will start the loader on the iPad, and load the OS.
- After iTunes said that is successfully restored your device, you may get an error message saying the iPad isn't recognized and you're still at the screen with the USB cable and iTunes logo on the iPad. Don't sweat it. Unplug the iPad from the computer. Power off the iPad by holding the sleep button until you see the "slide to power off" - go ahead and slide to power off. Once it is shut down, push the sleep button again until it powers on.
- the iPad will come back to the familiar USB cable/iTunes logo. When it does, just plug it back into your computer and iTunes will activate the iPad.
- if you had previously backed up your iPad, iTunes will tell you there is a backup and ask if you would like it restored. If you wish to do this, accept the prompt. This will also take some time. Note it will NOT put your apps, music, movies, TV shows, etc back on your iPad, just your settings and preferences.
- once the restore is complete, iTunes should recognize your iPad and you can pick your synching options (apps, music, movies, etc, etc) and have a blast! The only thing I noticed it doesn't retain is the page layouts for your apps, so either screen capture them before you begin, or write it down.
I hope this helps

HT1212 im locked out of my ipod, and the screen isnt responding when i go to swipe to unlock it or when i swipe to turn it off. But, in the top left hand corner, there is an outline of a box. how do i fix this

im locked out of my ipod, and the screen isnt responding when i go to swipe to unlock it or when i swipe to turn it off. All of my notifications are there but i cant reply to any of them. My screen is completly unresponsive. But, in the top left hand corner, there is an outline of a box. how do i fix this?

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.

IMac won't respond after being put to sleep/turned off.

I've been dealing with this problem for a few months now. If I put my hard disk to sleep or turn my computer off, it doesn't respond when I try to wake it back up or turn it back on. It will make a continuous clicking noise (no there's no disc caught in it the CD drive) and the only way for me to actually restart is to run the Archive and Install feature on the install disc. If I try to simply restart it, I get a blue screen with a folder-with-a-question-mark icon where the Apple icon should be during loading. I've had to skip putting the hard disk to sleep at all but I do just put the display asleep, and it wakes up fine after that.
I've noticed a lot of crashes with Safari and other things like games recently too. I'm usually able to just force quit the program and restart it though. I have a Logitech mouse and an Apple USB keyboard that I use with it and I've tried unplugging and replugging those, as well as trying other keyboards/mice with it to see if it's a rare hardware issue. The only thing I haven't checked yet is the RAM that my boyfriend installed for me a couple years ago.
Although, I've noticed the last couple times I've had to do that, I've had to wait to use the install disc. If I do it too soon after it's stopped responding then my hard drive doesn't show up on the selection menu and the Archive and Install option doesn't come up. I have to let it sit a little while before I can do it.
I'm not at home at the moment to see which exact model/generation it is, but I have the one with the flatpanel screen and built-in iSight. I bought it back in June 2006. I'm currently using Leopard on it (not sure which version though).
Could one of my boards be worn out? Or could the additional RAM be causing problems? Any advice or suggestions are welcome. I'd like try checking everything I can myself before having to take it in to an Apple store. Thanks!

I bought it back in June 2006.
If it was purchased new, you are better off posting in another iMac forum. This is for the G4 iMacs with the articulated display arm and the dome-shaped base. It's not your fault--the forum labeling is, at best, non-intuitive and confuses plenty of posters.
Look at "About this Mac" in your Apple menu and note the processor type. If it says "G5" then your forum is here:

If it says your processor is "Intel," then your forum is here:

If a reset doesn't work, try and force iPad into Recovery Mode:
1. Turn off iPad. Press and hold the Sleep/Wake button for a few seconds until the red slider appears, slide to turn off.
2. Connect USB cable to computer
3. Press and hold the Home button down and connect the docking end of cable to iPad
4. Continue holding the Home button until you see the "Connect To iTune" screen
5. Release the Home button
6. Open iTune (make sure you have the newest version of iTune)
7. You should see "iTunes has detected an iPad in recovery mode"
8. Use iTune to restore iPad
Note: You need to be patient and repeat the above many times to recover your iPad
