if mag safe is plugged into wall,but unplugged from laptop, does it still draw power?

My Kill-A-Watt meter indicates that my 85W MagSafe adapter draws about one watt when it's plugged into the wall but not powering anything. The meter doesn't measure fractional watts, so that's probably rounded up from a fraction.
When my 15" MBP is connected to the adapter but asleep, about two watts are drawn -- somewhat less than a small incandescent night-light.

  • Why is my 4th generation ipod touch not charge? I plug it into the computer and the wall and with 2 different usb cables and its not charging. When its plugged in it shows the icon for charging but the battery never increases and it dies once i disconnect

    I have a 4th generation Ipod Touch. It has been working for months when yesterday the battery started acting werid. I was driving and it was connected with the usb charger cable to my car stereo when all the sudden my music stopped and the stereo could not recognize my ipod at all. When I got back home, I tried to charge it so it wouldnt die but even while on the charger in the wall the battery continued to die. I charged it over night (the first time I have ever charged it over night) desperately to have battery for a 4 o clock plane flight so I would have entertianment. The ipod died over night while on the charger. When I unplugged it from the usb charging cable I noticed that the icon telling me the ipod needed to be charged came up. So I plugged it back in. The charging thunder bolt symbol popped up next to the very small red strip on the left side of the battery indicating that the ipod had no charge to turn its self on. I tried plugging it in on the computer, the wall ac charger and a stereo system made just for the ipod that also pluggs into the wall. I have used 2 different cables, the result being the same that the ipod held no charge, and it wouldnt charge at all while on the charger, and it would imediately die once i take it off the charger.
    I have not idea what has happened ....
    Please help
    THanks!

    - While charging try resetting the iPod:
    Reset iPod touch:  Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears.
    - Next try restoring the iPod via iTunes.  First from backup and if still problem restore to factory defaults/new iPod.
    - However, I really think that the iPod has a hardware problem and an appointment at the Genius Bar of an Apple store is in order.  If defective Apple should give you a refurbished iPod.

  • I have a Macbook Air purchased in 2011 in the US.  I am traveling in South Africa and am unsure if I need a step down voltage converter before I plug my laptop into the wall to charge it (using an outlet adapter).  Am I ok to just plug in?

    So standard electrical output from wall outlets in the US is 110V - 120V, and standard output from wall outlets in South Africa is 220V - 240V.  In SA I know I can plug in an iPhone using the iPhone charging cable and it will automatically step down the voltage, thus preventing my phone from overheating.  I cannot plug in a hairdryer or flat iron without step down voltage converter in SA.  Can I use the charger that came with my US 2011 Macbook Air and plug into a wall outlet in South Africa or do I need to purchase a step down voltage converter in order to charge my laptop while in SA?

    You only need a plug adaptor as long as the voltage is between 100 and 240 volts.

    Hi syvliebaby88888888,
    If you are having issues with recharging your iPhone's battery, I would suggest that you troubleshoot using the steps in this article - 
    iPhone and iPod touch: Charging the battery
    In particular, this section -
    Inspect the connector at the bottom of the phone:
    Make sure that there are no bent pins in the connector.
    Make sure that the connector is free from debris.
    If there are bent pins or debris, please contact Apple Support.
    Otherwise, continue troubleshooting.
    Make sure that the outlet you're using works.
    Make sure that the Apple USB cable and Apple USB power adapter work.
    Plug the device in to power and let it charge until your device turns on. This could take between 10 and 30 minutes. If you don't have an Apple USB power adapter, try connecting to a computer's high-power USB 2.0 port (not a keyboard). The computer must be on.
    If the device still exhibits an issue, try turning your device off and then on again while connected to power.
    If the issue persists, please contact Apple Support.
    Thanks for using Apple Support Communities.
    Best,

    The sort fields should generally be empty unless you've putting in custom values to sort solo artists by their surnames. You can apply common changes to thousands of tracks at once, just don't apply the wrong change because there is no undo.
    It is a good idea to backup before undertaking large scale changes. See this backup tip for a suggested approach.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below on this page to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit 
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; sudo crontab -l; } 2> /dev/null | open -f -a TextEdit 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    { launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; crontab -l 2> /dev/null; } | open -f -a TextEdit 
    Step 4
    ls -1A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

    BOB we need you urgently
    Perhaps Bob will see this thread, he is the professor in these cases.
    You do not use a WEP password but wpa/wpa2 on router and equipment.
    All equipment connects to WiFi, but for your iPad.
    Even with all other equipment WiFi off, you cannot connect your iPad.
    Your iPad connects to other WiFi nets correctly.
    All resets etc done on iPad and Router.
    Still I am not sure it is your router for sure, frustrating...
    I want to test 2 other things:
    1. in your iPad, set everything OFF in Settings/Cellular, turn off/then/on your WiFi, and see whether it will still not connect...
    2. If that does not do it: disconnect the router as well as the modem from the power, for 15 seconds, then reconnect the modem, let it fully start, then reconnect the routet let it fully start, turn of your WiFi in iPad, then on, and see whether it will connect.

    Since this is the second computer you've had this problem with, I recommend you look for answers on the iPhone forum. My thinking is it is an iPhone issue rather than a computer issue (unless it is some software incompatibility).
