Macbook Air 2011 battery problem

Hello guys!
I bought Macbook Air mid 2011 11 inch model with 128 Gb and 4 Gb RAM. In last weeks I saw my MBA after full charge (all night) have 100%, but after two hours is 10%. Is it normal? I just worked with Google Chrome, Time Machine and maybe some video in HD in MPlayerX. What I can do?

Ah, I made a reply yesterday evening, it has disappeared.
I try to repeat it again:
Don't worry: you have the most beautiful and enviable MacbookAir! It's the latest version, and it's battery is also new. I guess there's nothing wrong with it. The only thing that is different with my MBP's is that there is 6,4 power usage (obviously with the charger in), could you check one thing for me:
Start Acitvity Monitor (in Utilities), and for <all processes>, click on the %CPU column, are there any processes that continiously use more than say 15%?
The battery values vary a bit, that's not abnormal (in my MBP they vary between 92-103%; 90 cycles, 28 months), they are absolutely not giving the impression that there is something wrong with the battery, it's life is not determined by what Coconutbattery says (a good utility btw), but by the number of cycles, read the pages I gave the links of.
Another thing: there is an EFI update, look in the Software Update (EFI is an hardware layer, compare bios in a PC):
http://support.apple.com/kb/DL1448.
If you do not have "problems", it is still good to update, because it may solve some issue that you have not encountered yet.
don't worry, have fun with your fantastic 13" MBA,
happy computing,
Lex

OS X Recovery requries a broadband connection as noted > OS X Recovery
There's no need to hold down the Option key to restore OS X.
Hold down the Command + R keys.
If your download speeds are less than 10Mbps, you may not be able to restore your Mac using OS X Recovery.
If you can, take your Mac to an Apple Store > Apple - Find Locations
In most cases, they will restore OS X for free for you.

MacBook Air 11" Battery Problem

Just purchased the new MacBook Air 11" and only getting around 2 hours battery time as opposed to the 5 hours advertised.
I've had it about 2 weeks now and thought the battery might increase over the coarse of time, my main concern is I've only being using Firefox for browsing so nothing too CPU intensive and had hope to do some photoshop work on it at some stage.
Can anyone link me to any diagnostic tools to see if theres a problem with the machine. Activity monitor isn't showing anything unusual.

http://www.apple.com/macbookair/specs.html if you look at the bottom it notes the test was performed with just safari opened, and at 50% brightness. If you want similar battery life I would try setting the brightness lower; and make sure no other application is open. Also I would assume this test was done without flash installed.
Having flash installed will negatively effect battery life. http://www.geekosystem.com/flash-decreases-air-battery/ "reviews of the MacBook Air over at Ars Technica indicate that having Flash installed can cut the battery life by a third"
Apple actually posted a whole press statement why they chose not to include flash by default. http://www.apple.com/hotnews/thoughts-on-flash/

Macbook Air 2011 USB Problem

Hi, I recently bought a Toshiba portable hard drive that uses usb 3.0. For some reason, my mid-2011 macbook air 13" is unable to connect to the drive with the USB3 to microUSB3 cable. However, the hard drive worked on a late 2010 macbook air 11", other macbooks and pcs using the usb3 cable. The Toshiba portable hard drive did work with my 2011 air with my friend's USB2 to microUSB2 cable so I decided to buy one on Amazon. Unfortunately, the cable that I bought from amazon did not work with my macbook air but it did work with my other pc.
My question is: Does my macbook air have a usb problem and should I go to apple store to get it fixed?
Thanks!

There have been more than a few threads on this subject of the USB 3.0 Toshiba Canvio problems. Here is an ongoing rather current discussion of the issue.

Macbook Air 2013 battery problem

Hi all,
I just got my brand new Macbook Air 2013 model today, I can't power it up until the AC Adapter is connected. When I finished all the setups, login into the system, I found out the battery shows 0%. This is my first Mac, would like to know if this is normal. Cause from my experience with windows laptop, they all comes with pre-charged battery. Thank you very much for your assistance in advance.

That's not normal, & if it doesn't begin to work as expected after say, 15 minutes, try
Intel-based Macs: Resetting the System Management Controller (SMC)
but it's likely that you have a faulty computer.

USER: OS X Yosemite

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Whatever you read was incorrect. You can upgrade directly to Mavericks. It is in the App Store and is free.
Snow Leopard predates the operating system you already have. That's the reason it will not install on your MacBook Air. You spent $20 needlessly for it, but it's yours to resell if you wish.

I just installed MacOS X Yosemite on my MacBook Air 2011. After installing Yosemite I installed the Photoshop Elements 12.1 upgrade, but now when I open the program and try to use the tools, the program freezes. How do I fix this problem?

If you use a trackpad and don't want to switch to a mouse, you can uninstall and reinstall all day long and will still have problems, but if you really want to try it, you can download PSE 12 here:

My Macbook air 2011, one line of key board (a to l) do not respond, but when an external keyboard is hooked up these keys starts functioning as normal, after disconnecting the external key board (from the USB) the problem comes back...Please help. Thank y

My Macbook air 2011- key board (a-l) do not respond, but when you hook up an external key board to the usb these keys on the computer also starts functioning as normal and when you disconnect the external key, these keys stops functioning...?

Perform SMC reset
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Macbook air Shut down problem

Hi everyone,
I used to have the shut down problem with my Macbook air. I have an 11" Later 2011 Macbook air.
The problem did not go away after updating to Mountain lion.
I just realized that although I was closing all programs, I was not ejecting my 3G modem/dongle.
Once I ejected it before commanding it to shut down, it did shut down properly.
I thought I should share it with you. May be there is a program that has not been closed or a devise that has not been unplugged/ejected properly and is restricting the shut down.
It worked for me. Hope it will work for you.
Enjoy your Mac.
J.

    Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
     If this does not help, you may have to take the computer to the Apple store
     to have the battery checked out.
     Best,

MacBook Air 2011 Fan increased after installed mountain lion

Hi all,
I have a Macbook Air 2011, Intel core i7. After when I installed ML I noticed that battery go down very fast (about 2:40h) and the Fan speed RPM is about 6500 all time, but I haven't any strong operation pending or App. I have the same app open since lion (Internet, chat, jdownloader) in background (skydrive,evernote,weatherhd) the same app and background task I have with Lion.
In monitor activity all task is from 1% to 20-30% of usage.
Any Tips?

I only have the fan kick in when the graphics is getting hit hard (playing games, driving external displays, etc) with crappy intel on board graphics.
Is your MacBook Air in a protective case, skin or having anything block the vent hinge?
Definitely sounds like the OS thinks it needs to keep running the fan.
You might try this smart temperature desktop widget and monitor your temperature to see if there is any sane reason for the fans to be on (they are loud!).

After installing Mountain lion, macbook air 2011 very slow

After installation of Mountain lion my macbook air 2011 got very slow. There has been a firmware upgrade too. Can you help?

Hi guys! Just installed ML on my early 2009 MBAir (after market upgraded to a 240g SSD, but still just 2g of ram), and I panicked a bit at first when it turned out to be painfully slow and not displaying right (+slow trackpad!).
Bear in mind that the first thing ML will do is index your files for spotlight, which takes a while and is a bit of a resource hog that will slow everything else down and cause your machine to heat up.
I let it work all night, but by morning, my CPU usage was STILL at 100% and everything slow...
Activity monitor showed nothing over 10% CPU usage... First tip was to display ALL processes in Activity monitor, and not just MY processes, to see what exactly was sucking up my CPU!
Then, and it seems to often be the culprit on MBA's, it turned out that the kernel_task process was using up to 170% of my CPU usage (!). Problem is, that process sort of does a million things, so it can be hard to pinpoint the actual issue.
One of the things it does though, is work against overheating...
Given the download+install+indexing, my machine had been working all day and night, and was indeed getting super hot. Turning it off and letting it cool down for a whole fixed it all.
Kernel_task is back to normal, CPU usage is normal, display and trackpad are back to perfect. And in the end, ML is snappier than SL for me, even with the bare minimum in memory!
Good luck! <3

Time machine crashes macbook air 2011

Hello,
I'm using Macbook Air 2011 13 inches and running Lion 10.7.2
I'm trying to use time machine on an external hard drive.
But the time machine always crashes the whole computer while I leave the computer unattended for 2 or 3 hours. When I keep using it, it can perform hourly backup without any problem. Once i decide to leave my macbook unattended for over 2 hours, when coming back, the whole system crashes at the stage of backing up 0 KB of XX MB. I put the log below. I have changed the external driver so it is not the external hard disk that generates this problem.

My MacBook Air's battery health is decreasing.

My Macbook Air's battery health is decreasing. I bought it around a year ago. Now it's battery health is 85%. However, it keeps changing. From 85% to 88% and sometimes it hit 90%. Is my macbook's battery healthy? And is it normal, because I bought it a year ago.
Here are my battery's properties:
Cycles ; 404
Health : 85%
Design Capacity: 6700 mAh
Current Capacity: 5703 mAh

i have to disagree with linc davis's reply.
system profiler, or what they call the system report will have your current battery health status. in power the system profiler will either display "excellent", "normal" or "check battery" the more charge cycles you have, (404 which you stated) the more the battery will loose some capacity. this is normal of lithium ion batteries
health 85 % is current capactiy (fully charged) divided by design capacity * 100 or
5703 / 6700 *100 = 85%
my mac book air, having it for a year states
cycle count 163
Condition : Normal
Charge remaining 4223
full charge capacity 4263
but system profiler, at least on my mac book air running osx 10.8.2 does not list design capacity. so i am wondering where you got that number. the mac book air i have is the mid 2011 11" model
if you feel after 400 cycles your battery diminished and you have apple care you can always ask them to replace the battery, but if you did not get apple care, then the year warranty would be up. a new mac book air battery outside of apple care or any warranties is $129 before tax at the apple store.
eventually the more cycles you have ( a cycle is being fully charged from being nearly discharged ) the more you are going to have to replace the battery. whenever you feel you are not getting the charge you used to get the discision to repalce that battery is your choice, but eventually you will have to replace it.
for example say the battery used to give you 3 hours amd now it only gives you 30 minutes, then yeah replace the battery. but if the time lost in capacity doesn't bother you that much, then don't replace the battery now
