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 ...

    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 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.

  • 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!!

  • How do i install more memory in my macbook air? it only has 4GB

    How can i install more memory in my macbook air? it has 4GB only and it keeps telling me my start up disk is full.

    Welcome to the Apple Support Communities
    In the case of the MacBook Pro with Retina display and the MacBook Air, memory is soldered into the logic board, so you can't add more memory after buying the MacBook.
    However, memory isn't your problem. One thing is the memory and another thing is the hard drive, and you are running out of space in the hard drive, not in memory.
    To fix this, just delete files that you don't need, or move them to an external drive, in order to make free space on your MacBook

  • Why does my MacBook Air's shutting down slow down after the recent update?

    After the newly update OS X Update 10.9.4, the shut down of my MacBook Air slows down. It will stay several seconds more than before the update. This happens every time I try to shut down my MacBook, please meet my problem.

    A Safe Mode boot deletes some system caches that may help.
    Startup your Mac in Safe Mode
    A Safe Mode boot takes much longer than a normal boot so be patient.
    Once you are in Safe Mode, click Restart from the Apple () menu.
    Once your Mac has booted to the desktop, click Shut Down from the Apple () menu to test.

  • HP 23xi / 25xi compatibility with Macbook Air 2013?

    Hi,
    I'm looking to buy an external monitor (HP 23xi or 25xi) for my Macbook Air 2013 (10.9.1).
    Since the MBA doesn't have a HDMI output, I was wondering if a Mini DisplayPort-to-DVI can be used to connect the external monitor?
    I've gone through several forums, and many guys seem to have problems relating to blurry displays on their HP monitors -- when hooked up using DisplayPort-to-HDMI adapters
    So, can anyone confirm the compatibility of MBA with the HP monitor, and the adapter used?
    Many Thanks
    Piyush

    Hi Piyush90.
    I found information on Apple.com about a "Thunderbolt" connector that enables you to connect your Mac Book Air with other monitors. It doesn't state specifically what monitors it will work with but it looks promising that it will be a viable solution to your question.
    I've included a link below to the webpage about Thunderbolt.

  • Webcam not working for Macbook Air 2013 after upgrading to OSX Mavericks? Yahoo/ Google/Skype cam chats not working. Facetime works though. Any updates of Mavericks released to fix this?

    Webcam not working for Macbook Air 2013 after upgrading to OSX Mavericks? Yahoo/ Google/Skype cam chats not working. Facetime works though. Any updates of Mavericks released to fix this?

    I have a MacBook Pro Retina display: 15.4-inch late 2015 with OS X Mavericks install, only on second week. 
    Insight works on FaceTime, Skype, but yahoo program does not show insight cam in dropped down.
    Now when I got my new MacBook Pro, I down loaded all new Skype (worked tested), FaceTime (Worked Tested), Yahoo (not worked)
    Fix:
    With the new Maverick you have to use there messager program Version 8.0 (4218). Once I add my yahoo account video works again.
    It also supported AOL, AIM, Google Talk, Jabber.
    Guess I miss it frist time... hope this helps...

  • Yosemite does not recognize HP printer after upgrade.  I can print from my iPhone, but not my 13" Macbook Air (2013)Yosemite does not recognize HP printer after upgrade.  I can print from my iPhone, but not my 13" Macbook Air (2013)

    Yosemite does not recognize HP printer after upgrade.  I can print from my iPhone, but not my 13" Macbook Air (2013)
    Are others having the same problems?

    Try this. Worked for me.
    - turn off your router
    - turn off you Mac's after removing all available printers
    - turn off all iDevices
    - do a factory reset of your printer remove all cables min. 30 sec.
    - turn on your router first
    - ran the network set up wizard
    - give your printer also a new name like "DeskJet 2015"
       Something which you don't have used before.
    - turn on your Mac's and add your printer
    - turn on your iDevices at least.
    Should work after these steps.
    It worked for me including all iDevices.
    iOS and Yosemite

  • My MacBook Air which is only 3 months old, keeps on losing internet connection.  To reconnect I have to click on the internet icon on the top bar and click turn wi-fi off.  I then have to click turn wi-fi on and it reconnects after a few seconds.

  • 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.
    Separate thread
    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.

  • 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.

  • Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

    I have a Mid 2011 Macbook Air.
    Upgraded to Yosemite last week.
    Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
    I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
    After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
    If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
    I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
    I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
    I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
    I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
    I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
    Thanks,
    John

    Hi!
    I have exactly the same problem, and I can't find any solution.
    I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
    I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
    Any suggestion is greatly appreciated!
