Plugging in Superdrive shuts down the MacBook Air

I have a brand new MacBook Air. When I attach a SuperDrive to the Air it shuts down within a second. I've tried this with two different SuperDrives - a new one and one that I've already used. If I boot the Air with the drive attached the screen lights up and within 3 seconds the machine shuts down. Attaching a USB ethernet adapter to the Air works just fine. Suggestions?

Powered off is different from Shutdown. If it went to shutdown then it will run the processes. Powered off is more like the computer shut off.
From your description, it sounds like the safety switch turned off the system to prevent it from shorting out. I suspect that somehow when you connect your dvd drive to the usb port, it shorted the circuit. I am not sure about the details. But sounds like you need to visit the genius and get it fixed.

Should i shut down my macbook air each night

how often should i shut down my macbook air?

if youre not using it for a few hours
leaving your macbook both ON charge AND in sleep mode is bad on the battery
merely in sleep is another matter, which is fine.
Considerations for the long life of your MacBook. Handling and environmental care tips
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The only quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less on a frequent basis.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery). This is a minor consideration.
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

I try shutting down my MacBook Air but it wont let because the application "Mail" is still open but it will not let me close Mail so i can shutdown my computer

I try shutting down my mac but it says that it cant because "Mail" is open. so i try quitting mail but it will not let me!

Force quit Mail app. Apple logon in the menu bar select Force Quit. A dialog window will open select Mail.app and click the force quit button.
If that doesn't work hold down the power button until the system turns off. Then press it again to restart your Mac.

How can I unlock the remote desktop to shut down my MacBook Air?

My computer is locked as it says the Remote Desktop is attempting to reconnect and I can't get two other screens to close.
Ctrl+Alt+ Delete is not working....

Hi sunburnhaven,
I understand that you may have applications that are unresponsive. If the applications are still running, they may be preventing your computer from shutting down. Here is some information on how we can quit those applications:

Why does Mountain Lion take a long time to shut down my MacBook Air when I chose "Shut Down?" Much longer than before the upgrade.

Mountain Lion takes a long time to shut down. Much longer then Lion.
Any comments appreciated.

Shutting down the Macbook nightly?

I just purchased a macbook and the manuel says to shut it down if its not going to be used for long periods of time otherwise just put it to sleep. Well what about every night...should I shut it down or just put it to sleep and leave it plugged in charging while I sleep?

Yes.
I should leave it charging though right?
Yes.

I can't shut down my macbook air.

The problem starts when suddenly I can't move my cursor using my track pad. It happens that I'm not able to use my keyboard too. I tried to use a mouse to move the cursor and it works. Then I tried to shut it down by clicking the apple icon with my mouse, the screen went black for a moment then the computer automatically turns on again. I tried it several times and I still can't shut it down.
I would appreciate it if anyone could help me
PS my macbook is running on os lion

Press and hold the power button for about 10 seconds to force shutdown.
Reset SMC. http://support.apple.com/kb/HT3964

Best.

My ical won't stop upgrading, I can't shut down my macbook

when I click ical, it just started to upgrade by itself and it wont stop upgrading, and I cant quit the app neither shut down the macbook.

Jen,
First of all from the  Menu select "Force Quit..." and choose iCal.
Then try removing the com.apple.iCal.plist file from your Macintosh HD/Users/yourusername/Library/Preferences Folder. To find the Preferences folder, use Finder>Go Menu>Depress the "Option" key>Library. Drag the .plist file to your desktop, and log out/in or restart and check iCal for functionality.

My new MacBook Air keeps shutting down the screen while I use it

My new MacBook Air keeps shutting down the screen while I use it and has to be rebooted. I took it in to the Genius desk at my local store, but they couldn't find anything wrong and said that they have never seen this problem before.
I Spoke to the IT support guy at work. He has the same problem with his new MacBook, but not with his older one. He suggested that it is a software issue with all new MacBooks and is connected to the timing of it going into sleep mode. Does anybody have a solution? Apple doesn't seem to have one.

Try a SMC reset.

Why can't I shut down my MacBook unless I hold down the power key?

Hi all,
I have had this problem my MacBook Pro using both Leopard and Jaguar. It is a problem when I shut down using either the drop down menu or by the power key menu. It appears to shut down but when I close the lid the "sleep" light comes on and is steady. It isn't actually shutting down because if I don't have the power charger plugged in it will run out of charge.
So, to shut down, I hold the power key down for about 10 seconds.
If it does fall asleep I am unable to awaken it (the sleep light is steady) and have to go through the holding down the power key procedure to shut it down and then use the power key to start it back up.
Am I damaging it by doing this? I have tried the trouble shooting options as described in the manual. I had this problem before and one day it just wouldn't turn on and I had the hard drive replaced.
Thank-you very much for any help!

I have found a solution on another thread that seems to have solved the problem for me. That is, I haven't experienced since, either the double password prompt at wake from sleep or the issue of not being able to shutdown.
The solution requires deleting a preference file that apparently carried over from Tiger in the upgrade to Leopard and which is causing all the problems described. Preference files or .plist files hold configuration preferences and settings generally defined by the user for a particular operating system function. Deleting one of these files will result in the system recreating it on reboot with all settings set to default values, this is a simple way of fixing an incompatible/corrupt preference file.
WARNING: Deleting preference files will reset all configurations for that files associated function. Custom user settings made in the +system preferences>Hardware>Energy Saver+ preference panel will have to be re-configured by the user.

Oh-oh. Ext FW drive shuts down my MacBook and PC when I plug it in

I have an Acomdata 250 GB ext FW HD. Suddenly, whenever I plug it into my MacBook (10.4.9), it immediately shuts down my MacBook without warning. Ditto when I plug it into the FW port on my PC (Win XP Pro SP2). When I plug it into my Digital Audio DP G4, it doesn't shut down. But no computer recognizes the drive any more. The drive seems to boot up OK, but it's not recognized. Any ideas on what's wrong? The drive holds my iTunes music, so I am pretty freaked out if the data is lost forever (yes, I backed everything up on DVDs last week).
I tried different FW cables, with the same result. Other FW drives work fine with my Macs and PC. Could the HD enclosure be bad?

You should contact the drives manufacturer. If it does it on your Mac and PC it sounds like the drive enclosure may have a short somewhere. Luckily you backed up or you may have lost everything.

HELP! I shut down my macbook pro and now after applications have been in full screen mode for awhile they automatically minimize and it takes me back to the desktop. How do I fix this?

I shut down my macbook and now while applications such as safari have been open for awhile, even while active, will automatically minimize and it take me back to the desktop. How do I fix this?

I should add that this has happened before and I feel like it was a quick un-toggling of a box in my settings, but I can not remember what to do.

I shut down my macbook pro and now I started up and it started in the safe mode

I shut down my MacBook Pro yesterday and when I started up today, it keeps starting up in safe mode, what do I need to do?

Welcome to the Apple Support Communities
Does your Mac start properly in safe mode? If so, try resetting the PRAM > http://support.apple.com/kb/HT1379 This will reset the "boot args", so OS X should start into safe mode. Also, you should verify that the storage of the computer is OK, so open Disk Utility, select "Macintosh HD" on the sidebar and verify the drive. If there's a problem, start in OS X Recovery (holding Command and R keys while your Mac is starting) and repair it
