    Recharging my iPod shuffle (3rd gen.) on my 2009 iMac (OS 10.5.8) goes extremely slowly (via usb port at the back). This is mainly because recharging stops when my mac goes to sleep. I just can't believe that Apple doesn't have a sollution for this, but I haven't found it yet... What's the most efficient way of recharging?

    Purchase a wall charger for it instead.

    My Ipad 2 won't reboot. The little circle keeps going round but that's all, it won't boot. nothing happens when I press the button on the top either. Please help.

    After you hold the power and home buttons at the SAME time until the Apple Logo appears (ignore the red slider to shut down) then let go of both buttons and you don't need to do anything else.  Your iPad will restart all by itself.  Just be patient, but leave your iPad alone after the Logo appears.

  • Losing Home Sharing connection on Apple TV when Mac goes to sleep

    Just got the 2nd gen Apple TV all setup with home sharing to my Mac Mini library with all the wake on sleep options activated in OSX as well as the latest Airport Extreme router. However, when my Mini goes to sleep, the AppleTV eventually loses the connection and I have to physically wake up the Mac to get the library back (it's in a different room of course). If I connect via my laptop, iTunes still shows the Mini still active like it should (ie. everything is setup correctly and it wakes up when accessing the library)), but it looks like the AppleTV implementation isn't doing the same (perhaps Apple can fix this in an update). Has anyone else successfully been able to access the home sharing library once the Mac goes to sleep? I'd hate to have my Mac on all the time and thought the whole purpose of the new Airport Extreme and wake on LAN options in 10.6 Snow Leopard was to be able to do this. Any suggestions or tips? Thanks

    I have a similar but slightly different problem. My Mac never goes to sleep so that's not my problem. My problem is that I sometimes work from home over a secure VPN connection. While logged into the VPN the Apple TV cannot see the iTunes server, which is behavior I expect. But when I log out of the VPN network the Apple TV will still not see the iTunes server. I have to turn off home sharing, and turn it back on. Or quit iTunes and start it back up. Then the Apple TV will see the library. I think my issue and your issue have the same root cause.

  • My iphone 4S doesn't show the volume controls when playing videos and the speakers don't sound. But if I plug in the earphones then I can hear fine and the volume controls appear on screen. Please someone help.

    After a week or so of installing IOS 7 now I having this problem, the speakers don't work for videos, music or apps sounds, but they work fine for using the speaker phone. It's definitely some software issue as the volume control appears when i plug in the earphones, but disappears when unplugging them, same happens with the volume buttons on the side, they don't work when trying to use the speakers, but the work when using the earphones. Please help if you have a workaround for this. I don't want to carry my earphones all the time to listen to videos and music.

    - Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
    Try the following to rule out a software problem
    - Reset the iPod. Nothing will be lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup
    - Restore to factory settings/new iPod.
    - Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack or other hardware problem.
    Apple Retail Store - Genius Bar
    If not under warranty Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.

    A third-party place like the following will replace the jack for less. Google for more.

  • Can time machine back up if the mac goes to sleep?

    I started to set up Time capsule to have time machine back up my 2 macs and realized they were both set up to go to sleep after 20 minutes of inactivity. As this is the first backup it will take some serious time so i planned to do it at night. The question is can Time Machine do the backup if a Mac goes to sleep?

    The machine won't sleep if it is backing up.
    If it does, just set it not to sleep for a few days.

  • When my macbook goes to sleep from non activity when I return the wifi is not on.  When trying to log back onto my hub it says it is out of time and I have to reboot each time.  Most annoying, any solutions please?

    If you are not using data and the iPhone goes to sleep, it will automatically drop the wi-fi, and will not reconnect until you wake the phone up. That is the way it is designed. The only way around that is to turn off cellular data while at home and on wi-fi.
    Cannot answer the xbox question since this is an iPhone forum and I would have no idea.

  • Error after my Mac goes to sleep after streaming music?

    After streaming music and stopping for a while, my Mac goes to sleep and I receive the error in the attached screen shot when I try to stream again. The only thing that seems to work is quitting iTunes an reopening. Why does it do this and how can I stop it from doing this? Thanks.

    Hello Media Fred,
    It sounds like you are getting this message after the computer wakes from sleep, and you need to restart the iTunes application to get it to work correctly. I recommend signing out of your account first:
    Choose Store > Sign In (or Sign Out).
    From: iTunes 11 for Mac: Manage your iTunes Store account
              http://support.apple.com/kb/PH12299
    Then restart your computer, and sign back into the iTunes Store and test the issue.
    Thank you for using Apple Support Communities.
    Cheers,
    Sterling

  • After upgrade to Lion, iPhone won't charge after Mac goes to sleep

    I did a clean install of Lion, and have run Software Update. There are no problems with the system, but I noticed that when I plug the iPhone in to the Mac, it won't charge when the Mac goes to sleep.
    The iPhone gives the normal charging tone when it gets plugged in, and if I l press the Home button, it displays the charging screen. If I select Sleep from the Apple menu, the Mac goes to sleep and the screen on the iPhone blinks on as if not plugged in, showing the normal unlock screen. When I wake the Mac, the phone beeps and shows the charging screen.
    Is there a setting I can change to get the iPhone to continue charging after the Mac goes to sleep?

    This behavior is new in my experience, having been on Snow Leopard. I've always just plugged the iPhone into my keyboard since it is very convenient, and it has always charged overnight, even while the Mac slept. So this is not normal behavior for my system.
    My question is, has this changed in Lion?

  • Touch won't stops charging when my eMac goes to sleep

    My new 2G Touch connects and syncs fine with my eMac. It charges fine too. But the minute my eMac goes to sleep, the charging stops. Can that be fixed? Is it a USB 1.1 problem?

    My eMac did the same. The power going to Firewire and USB ports is shut off when the computer is asleep. Don't think it can be 'fixed' - it's just a design decision on the eMac. I believe newer Macs do continue to power external devices whilst asleep though...
    Maybe you could plug it in to an externally powered USB hub?

  • Apple tv loses home sharing when my computer goes into sleep mode

    Just recently, my Apple TV says that home sharing is off when my computer goes into sleep mode.  It never used to do that - any suggestions?

    I have the same problem here. Always back-ed up with Time Machine (OSX 10.9 Mavericks) to Western Digital drives. MyBooks, MyPassport 1TB (USB 3.0), all works fine. Time Machine is actually doing back-ups overnight. Since I got this new 2TB MyPassport Ultra USB 3.0 it's working perfect during days, but every morning when I wake up the MacBook from sleep, I get this annoying error:
    Time Machine couldn’t complete the backup to “MyPassportUltra”.
    Unable to complete backup. An error occurred while creating the backup folder.
    Latest successful backup: Today, 02:27 am
    I'm also not able to write anything to that drive, or unmount it. It stil shows up in Finder, and I'm able to read all the data perfectly fine. When I do a Disk Utility Verify Disk directly after, I get this:
    Checking volume
    disk3s2: Scan for Volume Headers
    Invalid Volume Header @ 0: I/O error
    Invalid Volume Header @ 2000021315072: I/O error
    disk3s2 is not a CoreStorage volume
    Error: This disk needs to be repaired. Click Repair Disk.
    I don't click Repair Disk, as this will probably screw up my partition. Instead, I have to unplug the USB cable (which is bad for the drive, there's no time to park the drive's heads) and plug it in again. After clicking Backup Now, Time Machine immediately starts backing up, and the drive works fine the rest of the day.
    I contacted WD Support, and they are sending me a booster USB cable. As System Information reports, the drive receives enough power though:
    Current Available (mA):          900
    Current Required (mA):          224
    Unfortunately there's no firmware update for this drive, which will probably fix this. See this topic: https://discussions.apple.com/thread/4196704.
