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.

1. Follow these instructions, or these for OS X 10.9 or later.
2. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
3. You can also try resetting the SMC.
4. Make sure your system is up to date in Software Update.
5. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

MacBook Air 2013 Camera Problems

I have a MacBook Air 2013 and recently, after the most current update my built-in camera not only does not work with Skype but does not work with Facetime or Photobooth either.
Under "Camera" in System Report my camera does not show up. I have rebooted, shutdown and cold-booted, pressed Shift + Alt + Ctrl + Command when booting.
I don't want to do a fresh install of my (brand new) computer all over again just yet. What should I do? Is it a software issue?
It's rather frustrating because I can't Skype or even Facetime my family and resorting to an external webcam is a ridiculous notion for a laptop.
Thanks,
scintoon

Hey dominic23,
Thanks - that update solved the issue of me not being able to use the webcam. However, now my mic does not work as well. I have rebooted a few times (shut down, cold boot) as well as holding the Shift + Alt + Command when powering up.
Is there a fix to this? Apple seriously needs to fool-proof these updates. Or, at least never have any of these problems in Mavericks
Thanks for all your help.

Macbook Air 2013 - Sleep Problem

The new macbook air 2013 13' sometimes goes right back to sleep after 5 seconds from waking up. I was wondering if this was happening to other macbook air users and wondering if I can fix this.
Thanks

Well the strange thing is i had this problem too went to the apple store couple of times and they mentionened twice that they are aware of this problem and it will be fixed in an update......
A month ago i spilled water on my mba and motherboard was replaced funny thing is with my old drive and only motherboard replaced i do not have this problem anymore....therefore i am allmost absolutly sure this was hardware issue.
Apple's got a hand on denying this sort of issues because if they acknowledge you can let your mb replaced for free.... but of course you never know for sure and thats what they know....

MacBook Air 2013 battery drains quickly while in sleep mode

I just purchased a 13" mid-2013 MacBook Air this week, and so far everything is working well - a remarkable improvement over my 2007 MacBook! But, I've noticed that the battery seems to drain very quickly while in sleep mode. For example, it drained 10% over five hours. I've turned off bluetooth and made sure that the PowerNap option is not selected under Energy Saver preferences. And the battery health/capacity seems to be good. Are there other things that I should turn off/check out? Has anyone else experienced this? Is this even abnormal for the battery to drain at this rate while in sleep mode? Thank you!!

Macbook Air 2013 USB problems (won't connect/ reconnecting)

I have a new Macbook Air 13-inch Mid 2013 with all the upgrades possible (1.7 Ghz i7, 8GB RAM, 512 GB SSD). I am running Mac OS X 10.8.5. Every software is at the latest version.
I am having troubles connecting a couple of USB 2.0 devices to the Macbook. The first one is my phone. It's a HTC One and when I plug it in dmesg gives this output:
USB (XHCI Root Hub USB 2.0 Simulation):Port 2 on bus 0xa connected or disconnected: portSC(0xe0206e1)

The Identifier message keeps repeating every couple of seconds until I plug the phone out. It also won't show in System Report -> USB.
The second device is a Kinect for Windows (Model 1517). Here it is almost the same. dmesg gives me the following output:
USB (XHCI Root Hub USB 2.0 Simulation):Port 1 on bus 0xa connected or disconnected: portSC(0xe0206e1)

USBF: 6916. 69 The IOUSBFamily was not able to enumerate the device (Port 2 of Hub at 0x14100000).
These three lines keep repeating every couple of seconds until I plug it out again. But here I get something in System Report -> USB:

This is still a little strange because there are supposed to be 3 devices (the motor is missing).
So, I haven't yet had the chance to test on other computers but I will try to get my hand on one this weekend. And I will buy an external powered USB-hub to see if it is a power issue, which I doubt because the phone doesn't need that much and the Kinect comes with an external power supply.
Any idea how I can use my hardware? Is there anything more I have to look for? Known bugs? Do you need more information? ANY help is highly appreciated!
Thank you!

For me the issues are resolved but I guess it won't help you much. Sry.
The HTC One could not properly connect because the USB cable was broken somehow. I bought a new one and it worked ever after. It's crazy because I tried 3 cables before (which I had successfully used with other devices), but they were all very cheap, from the same manufacturer and bought at the same time. Must have been a bad batch or something.
The Kinect was a different story. Here the problem was that the firmware was not compatible with the driver on the MAC. I did some research and since I can't make my own drivers I got myself another Kinect with an older firmware and that resolved this issue.
Good luck.

MacBook Air 2013 Internet problems

I just recently ordered a 2013 MacBook Air and it arrived in the mail today. All was going well until I began to encounter problems with the Internet, repeatedly. When it's working everything is fine and dandy, but sometimes when I am trying to look something up the bar will just stop loading the new page, and I'm stuck there until I restart it or log off and back on again. When the bar stops loading I can't do anything that requires Internet, until I choose one of my two previously said options. Can someone please help me? I bought this machine for college, and if im having these (very) frustrating problems already I'm going to go crazy! Unfortunately I'm not one of those tech-savvy people who can change their Internet channels and such!! Please help!

The warranty entitles you to complimentary phone support for the first 90 days of ownership. If you bought the product in the U.S. directly from Apple (not from a reseller), you also have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different.

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

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 2013 battery only has 4hour after the icon shows 100%

As title, when I charged the battery of MBA to 100%, the using time only shows about 4~5 hours.
I think that should be 9 hours.
Does my MBA have problem?

Runaway applications can shorten battery runtime ...

IPhone 4s keeps connecting and disconnecting from my new Macbook Air 2013

Ok I've been having this problem, I recently got an 11 inch Macbook Air 2013 and after I try connecting my iPhone 4s it keeps connecting and disconnecting every 1-2 seconds. I already check the community, I know this subject has been asked many times. Nothing worked out though. My cable cord must be fine because it works perfectly on my PC. I updated the OS and iOS to their latest firmware and still nothing. Whenever I try opening iTunes I get this message saying " iTunes could not connect to this iPhone. This device is no longer connected. " Please if anyone fixed this issue I would appreciate some help. Thanks in advance.

I just solved it, I hope this helps everyone who is experiencing the same problem. Apparently the iPhone seems to charge normally and connect to iTunes if the iPhone battery is over 60%-70%. This must be a power issue the MBA has.

Macbook Air 2013

I just got myself a new Macbook Air 2013 and while I realized I couldn't expect the smoothest experience, I never expected this much hassle with it. So many differnet issues. No need to have a sad face about it, though - let's get together and figure out how to make this work! At least we only have one graphics chip to worry about this time around
This is going to be a pretty long post but I figured it's good to have it all in one place. Please correct me if you think this is the wrong way to post these things.
Installing and booting
Booting from a normal 2013.6 USB key works fine, but I couldn't seem to get either GRUB or Syslinux working.
I was able to boot by first installing Arch Linux following the Macbook guide at the wiki (having a separate FAT32 /boot partition). Skip the bootloader installation.
Installing rEFInd from OS X (important!) and installing the EFI stub loader made me able to boot fine.
Separate thread.
Stability problems
This is the big worry for me. Every now and then my system hangs for a brief moment and everything involving net or disk access just hangs there for a while and then it seems to work.
So far it only seems to happen when I run something disk- or CPU-intensive. Also had an occassion when I couldn't start X and just got this repeating all over my screen:
ata1.00: failed command: WRITE FPDMA QUEUED
ata1.00: cmd 61/08:f0:10:8c:c2/00:00:0b:00:00/40 tag 30 ncq 4096 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata1.00: status: { DRDY }
On the next attempt it worked fine.
I did SMART short and long tests on my disk and they returned fine:
smartctl -a
There are some messages in my boot that indicate this could be disk and/or ACPI related.
journalctl -b
dmesg
This was on a boot when my NIC was renamed from eth0 to wlp3s0 as noted under Wifi - this should hopefully not be a big deal to fix. Will update when I look more into it.
uname -a:
Linux temperance 3.9.7-1-ARCH #1 SMP PREEMPT Thu Jun 20 22:45:32 CEST 2013 x86_64 GNU/Linux
WiFi
WiFi does not work out of the box. Installing wireless-bcm43142-dkms from AUR made me able to connect to my network. I haven't been able to get it stable yet -interface name changes randomly between wlp3s0 and eth0 between reboots and I get disconnected from my network every 30 minutes or so. Disconnects seem to correlate somewhat with the freezes mentioned above.
Separate thread.
Touchpad
Have only been able to get it to work like a one-button mouse using evdev for now. Looks like an upstream bug.

Audio
In order to get audio, I need to put the following in /etc/asound.conf:
defaults.pcm.card 1
defaults.pcm.device 0
defaults.ctl.card 1
I'm no ALSA pro, but I can only seem to get output from the headphone jack so far - no speakers yet.

While I'm using Ubuntu and not Arch, I wanted to chip in with my experiences.
First, I am happy to tell you that I've found a fix for the ata errors/freezes (which for me were so bad I could hardly install) -- at least I think it's the same or related. I got udevd spitting errors about blkid timing out, and it couldn't find the disks. I found this in a Ubuntu forum -- sadly, I can't find the url now. Anyway, Pass
libata.force=1:noncq
to the linux kernel parameters (in Ubuntu you can add this to /etc/default/grub). This disables NCQ, which according to that post wasn't needed.
YMMV and I am not certain that it doesn't have bad side effects, but for me it made the laptop usable.
Other findings:
My Fn key, and thus delete, page up/down, media keys etc didn't work. That's because the keyboard has a new device id which isn't in usbhid. I added entries like the existing apple keyboards with the new device id (05ac:0291) and after recompiling, it works. I'm pretty sure this is fixable by passing the correct "quirks" flags to the usbhid module, e.g. "quirks=0x05ac:0x0291:0x00001248", but I'm not sure which flags should be set (I have an ISO keyboard layout which is yet another flag).
My sound card doesn't work. Or; i hear no sound at least ;-). After checking in alsamixer, it had two cards, one HDMI with S/PDIF only and one with analog in/out and digital in. I tried passing "index=1" to snd_hda_intel, which makes alsamixer pick up the right card by default. I'm not sure if the problem is that pulseaudio still has the wrong card, or something else.
My wifi works after installing bcmwl from Saucy (i.e. the upcoming Ubuntu 13.10 release), which was a relief because I feared this not being supported.
Sometimes after resuming from suspend, the screen is totally dark -- barely discernible in bright daylight. First I figured this was an issue with lightum (a daemon which monitors the lighting and adjusts keyboard and screen brightness), but after checking /sys/devices/pci0000\:00/0000\:00\:02.0/backlight/acpi_video0/brightness it turns out that when this happens, only the brightness levels 13, 14, and 15 (which is the brightest) have any brighness at all. 12 and under means no backlight. The only "fix" I've found so far is rebooting, which sucks. I hope this will get fixed (I will report a bug on Launchpad next time it happens).
Somewhere I picked up that passing
i915.i915_enable_rc6=1
to the linux parameters enables some great power saving features in the GPU. From modinfo:
i915_enable_rc6:Enable power-saving render C-state 6. Different stages can be selected via bitmask values (0 = disable; 1 = enable rc6; 2 = enable deep rc6; 4 = enable deepest rc6). For example, 3 would enable rc6 and deep rc6, and 7 would enable everything. default: -1 (use per-chip default) (int)
Oh, and if anybody knows how I get my GNU/Linux partition to show up in the Mac boot screen I would be grateful! Right now I have refit installed, which works but I would rather just use the built-in boot manager, which works on the predecessor (MBA 3,2).

HT1379 A flashing question mark appears when I re/start my MacBook Air 2013. At first, I pressed Power & Option button and it recovered from Internet. Then, four options appeared but none of them are helpful. Could u please help me to solve it asap?

Hello,
A flashing question mark appears when I re/start my MacBook Air 2013. Then, I pressed POWER & OPTOIN buttons and internet options appeared for internet recovery. After internet recovery, the OS X utilities appears with four options (Restore from Time machine, Reinstall OS X, Get help online and Disk utility). But none of them seemed helpful. On the last option Disk utility, the icon created only with 33KB and other disk 1 Mac Os X Base system. On First Aid, the icon Repair disk is disabled. So I could not click on repair disk. Could you please suggest me how to solve this problem asap? Thank you so much for your help in advance!

You can try the following:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
