Is there Sudden Motion Sensor in last Macbook Air with SSD?

Can u help me with this question please?

No there is not.
It's a bit of a shame too, because although the sensor's original purpose is simply to help guard a spinning platter type hard drive, some enterprising programs actually co-opt the sensor to provide positional input. An example would be a game that relies on the tipping of the notebook to control an aspect of gameplay.

  • Why is there suddenly no audio from my macbook air?

    Why is there suddenly no audio on my macbook air?

    did you put your Air to sleep with headphones attached, or closed the monitor with phones attached?
    Do not sleep your Air (close the monitor with headphones attached) with headphones attached, this is known to affect some Air under Mavericks.
      * this occurrence is being looked into.
    Much testing on my own and others as well show that, in some instances, this occurs in Mavericks.
    If you choose you may contact Apple for an appt and diagnostics.
       However as said, refrain from having phones attached when you close the monitor to prevent this until it is resolved
    Test this and re-verify

  • Sudden Motion Sensor defect on MacBook ? Could you test your MacBook ?

    Hi !
    Got my new MacBook black.
    I wanted to test the Sudden Motion Sensor with amstracker and amsvisualizer.
    But only the x and y values change....the x value stays on 0 and sometimes jumps to -1 when i tilt the MacBook ?
    Is it a defect or a Bug ?
    Please test yours and write back !
    Thanks

    Apple seems to frequently change the details about
    how to access the SMS data making previous versions
    of SMS-reading utilities useless on the new machines
    until they're updated. Almost certainly software
    incompatibility rather than hardware failure.
    I would have to agree with this as the visualiser that you gave don't work right on my MacBook.

  • Sudden Motion Sensor / Seagate Momentus 7200.4

    All,
    I am trying to check the Sudden motion sensor on my macbook pro unibody 2.8. Reason being i am a seagate momentus 7200.4 500gb (p/n ST9500420AS) drive and i want to make sure it is on. because I dont hear the drive park when I move it.
    I go to terminal and do the following
    When the command line appears, type sudo pmset -g and press Return.
    Type in the administrator password when prompted and hit Return. This command queries the computer for the current setting of the Sudden Motion Sensor, which you can determine by locating the ams entry (in Mac OS X 10.3) or the sms entry (in Mac OS X 10.4 and 10.5) and looking to the right to determine its value. The default setting is "1" (turned on).
    But it shows no setting. After I type the password it shows a blank line. How come I can not see this setting?

    The SMS is not a part of the drive itself, it is a separate component normally located adjacent to the drive. It consists of a three-axis accelerometer that reports any motion of the computer to the Operating System. If it exceed a certain threshold, the O.S. causes the drive to park itself, presumably in anticipation to an impact. Some general purpose utilities, such as [MacPilot|http://www.koingosw.com/products/macpilot.php], allow you to enable or disable the SMS, there are also utilities specific for this.
    An interesting application is [SeisMac|http://www.suitable.com/tools/seismac.html], which reads the info produced by the SMS and displays it as a graph, turning your Mac into a seismograph.
    As for the operation of the system, I've found that if you close the lid on your portable and while it is updating the sleep image (before the LED starts pulsing), if you shake it, you will hear and feel the HDD coming to an emergency stop.

  • Hard drive upgrade on 13" MBP sudden motion sensor compatibility

    Hello,
    I'm planning on upgrading the hard drive in my 13" MBP (aluminium unibody) and I've read a lot of posts regarding the sudden motion sensor conflicts with OS X 10.6.2. I'd like to know if the Western Digital 500GB Scorpio Blue here (http://www.dabs.com/products/western-digital-500gb-scorpio-blue-5400rpm-sata-300 -8mb-58P6.html) would suffer from the conflict (I'm not sure if "Shock Guard" = sudden motion sensor). I don't know if its a simple yes/no or whether its drive / mac specific.
    If it would be a problem does anyone have a suggestion for a guaranteed compatible 500Gb hard drive (5400 rpm is fine)?
    Any thoughts are much appreciated, thanks for your help!

    Western Digital Lists their drive features as:
    * IntelliSeek™ - IntelliSeek technology calculates optimum seek speeds to lower power consumption, noise and vibration.
    * SecurePark™ - WD's SecurePark technology parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved shock tolerance.
    * ShockGuard™ - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation.
    * Free-fall Sensor - As an added layer of protection, if the drive (or the system it's in) is dropped while in use, WD's free-fall sensor detects that the drive is falling and, in less than 200 milliseconds, parks the head off the disks to help prevent damage and data loss.
    * WhisperDrive™ - WD's exclusive WhisperDrive technology combines state-of-the-art seeking algorithms that result in one of the quietest 2.5-inch drives on the market.
    The Free Fall Sensor is the equivalent of the Sudden Motion Sensor. Looking at the specs for the drive you linked to... they list the following features:
    Shock Guard, WhisperDrive, SecurePark
    As they do not list Free Fall Sensor, I'm guessing this model does not have one so it should not conflict with the internal Sudden Motion Sensor in your MacBook.

  • Tilted sudden motion sensor in MacBook ?

    I have download an application called "AMSVisualizer" to monitor the current reading of the sudden motion sensor. It will display a MacBook Pro/PowerBook and also display the readings of the sudden motion sensor in real time. When you move the laptop (even very slightly like typing the keyboard), it will sense and display some vibration. But my result is strange : I run the program when my MacBook is place flat on the desk and the "x" reading is flashing between 13-15, and the MacBook in the display showing that it is placing on a "non-horizontal" posture. I have to lift the left portion a little bit in order to make the "x" axis reading to 0.
    Here is the photo as what I described above:
    Tilt

    Can some of the MacBook owner to test on this application to check your result ? The application could be downloaded here:
    http://www.osxbook.com/software/sms/amsvisualizer/
    Thanks!

    Agreed with Jonas Hurtig. As you can see in my photo, I have to place the MacBook battery on the left side of the MacBook in order to have the reading looks normal. That is about 10-degrees tilt, there is no measurment needed for such situation if the desk is tilt like that, yor pens, desktop will slide off.....

  • Second Hard Drive, Sudden Motion Sensor

    Back in the fall I put a SSD in my 2007 MacBook Pro. It's working perfectly. I found the "OptiBay" product, which basically replaces your optical drive with an adapter for another hard drive. I haven't received it yet, but when I do I plan on installing it with a traditional hard drive. My question regards the sudden motion sensor (SMS). I disabled it because it's not needed for the SSD, but I was planning on re-enabling it for my secondary that I will be installing. I'm still going to boot off the SSD, though. Is there a way, or terminal code, to assign the SMS to a certain disk? I'm assuming it will just disable the root drive in the event of "sudden motion," but would this affect a secondary drive?
    I'd love for there to be an option to change the identifier, from disk0s2 to disk0s3, but I have a feeling it isn't possible or would be infinitely more difficult... thanks.

    Most drives are available with the equivalent of an internal SMS. You just have to check the specs. Drive manufacturers often offer two versions of their drives... one with and one without a SMS. If you get a drive with the SMS built in, you can just leave the MacBook's internal one disabled.
    Here is an example of one of the most popular drives:
    http://www.seagate.com/www/en-us/products/laptops/momentus/momentus5400.6g/
    Seagate's SMS technology is referred to as G-Force. Note the product number: 5400.6_g. The "g" denotes the drive has a "G-Force" sensor.

  • 2011 MBP - HD in Optibay - Sudden Motion Sensor?

    2011 15" MacBook Pro with BTO Apple SSD.
    Optibay with WD 750GB Scorpio Black.
    What is the correct setting regarding the Sudden Motion Sensor?
    There is conflicting information that this drive does or does not have a SMS - according to WD's website it does have "ShockGuard"
    There are several that have had trouble with motion sensor in a hard drive, in the optibay and in the Mac software. Some have not... and it seems to depend on drive.
    What is the correct setting - should one turn OFF Sudden Motion Sensor in the operating system? or leave it on?
    and either way, does SMS or "Shockguard" work properly when in an optibay?

    Jim,
    I have a similar setup to yours. SSD in main MBP drive bay, and WD 750GB Scorpio Black in the optibay.
    Ok, so we know that:
    SMS doesn't work in the optibay.
    Having the boot drive in the optibay causes hibernation issues, which could be "solved" by disabling hibernation and its creation of the /var/vm/sleepimage file.
    WD has something called ShockGuard on their Scorpio Black drives:
    "WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation. WD’s SecurePark parks the recording heads off the disk surface during spin up, spin down, and when the drive is off. This ensures the recording head never touches the disk surface, resulting in improved long-term reliability due to less head wear and improved non-operational shock tolerance." [http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701275.pdf]
    I'm wondering if, after a few months with your setup, you still consider the WD ShockGuard to be a sufficient reason for leaving the WD Scorpio Black in the optibay.
    My initial instinct is that ShockGuard may not be as effective as SMS. I wonder, in part because whenever the Scorpio Black is accessed (via spotlight usage or what have you), it stays spinning for quite a while before eventually spinning down. Do you experience this? Do you have any more advice from your experience?
    Thanks.

  • Is this a problem with the Sudden Motion Sensor or the HDD?

    I have a MacBook that I purchased in Septemberof this year, and for a while I have been having a problem with the HDD. I understand that there is a Sudden Motion Sensor that parks the hard disk when the computer is moved suddenly, but every hour or so I can hear the HDD make a single loud click for seemingly no reason at all. The computer can be sitting on my desk with no applications running and this will still happen. This is not really much of a problem other than the annoying noise, but if I am playing music or a video from the HDD it will skip when it does this. I have disabled the SMS for now to see if it will make a difference, I am very careful with my devices so I do not fear that I will cause any HDD damage without the SMS, but I am not sure if it is a problem with the HDD or the SMS. Could anyone shed some light on this for me?

    Well turns out disabling the SMS did nothing so I'm going to just take it in and hope it can be fixed.

  • Disable sudden motion sensor?

    Does anyone know if there is a way to disable the sudden motion sensor? Often I get frozen for a few seconds and I think it's because of the sensor.
    Suggestions?
    Thanks.

    I think it’s doubtful you’re experiencing spurious SMS activation, but I suppose it’s possible. The answer to your question about deactivating it is given on this Apple documentation page:

  • About Sudden Motion Sensor

    Lately, I heard about this thing which called as Sudden Motion Sensor. Yes I do why it’s built in mac but is there one in MacBook Pro 13 inch which comes with 2.66 GHz processor?
    And I heard about the games that uses this sensor but when I downloaded neverball and tried it in my mac. It didn’t worked as I saw in youtube.com (in the video the man was moving his mac). So, does this mean that my mac doesn’t contain Sudden Motion Sensor? Or there’s something that I need to do to operate it with such games?
    and thx in advance

    People have used it for many different things. Just search for "sudden motion" at VersionTracker or MacUpdate, for example.
    It's also been used for game control in the iPhone, iPod Touch, and iPad.

  • Sudden Motion Sensor as input device?

    So, I know this isn't necessarily that practical, but I'd be interested to know if it were possible, just for laughs and novelty. Is there any program, or could a program be made, that would allow the Sudden Motion Sensor to be used as a basic MIDI Controller / input device in GarageBand or Logic?
    I (lightly) drum on the palm rests of my macbook pro when I'm working on drum parts and was thinking that if the SMS is as sensitive as I hear it is, there must be some way where one could actually input drum parts this way...

    Yup. All Mac laptops now have the SMS.

  • Sudden Motion Sensor (Mobile Motion Module)

    Okay folks, it's my turn to ask a question this time.
    I worried about upgrading my hard drive, fearing that the Sudden Motion Sensor was built-in to Apple's OEM installed drives. I researched on the web prior to doing the upgrade (myself, by the way) and all sources pointed to the Sudden Motion Sensor being a "software"--for lack of a better term--feature that was independent of the hard drive, and regardless of what hard drive you have installed.
    I trusted that information, and now that I have installed, successfully, a new 160GB Seagate 5400.3 hard drive?
    My Sudden Motion Sensor doesn't work. It doesn't show up in the System Profiler like it used to, and it won't work with VirtueDesktop where there was feature that allowed me to switch desktops by "flipping" the PowerBook (not violently). And the best tester of all was the program, Seismac. It simulates earthquake movement readings, and any type of reading using the motion sensor.
    I just opened up the application, and it says there is a problem detecting the Sudden Motion Sensor feature and will not run.
    My PowerBook is the 1.67GHz/1.5GHz model A1106.
    Thanks for any suggestions, and help. (I put everything back together correctly, I believe, after the installation of the hard drive).

    I don't remember where I read it, but I read that if you put in a hard drive--like the one you mentioned, but that can't work in our PowerBooks or any for that matter--that has its own built-in Sudden Motion Sensor type technology, it will conflict with Apple's "software"-based technology.
    I wonder if Seagate's 160GB 5400.3 drive has it? I haven't read proving this.
    Plus, since my last posting, it shows up, goes away, shows up, goes away. One day two weeks ago, the Sudden Motion Sensor showed up as being enabled in Apple System Profiler. Excitedly, I ran Seismac. It started up, but then?
    FROZE. And the entire machine locked up as well. (PC?).
    Now don't get me wrong, anyone reading this. This Seagate drive is fabulous. It is the conflict with Sudden Motion Sensor that I'm trying to decipher!
    So again, anyone out there with similar findings, be it a similar Seagate drive, or any other hard drive upgrade, let us know your findings. =)

  • Sudden motion sensor, should I (or can I) disable it?

    hi there.
    I've just upgraded the hard drive in my MacBook to a Hitachi 250 Gb drive (model number HTS542525K9SA00). I'm really impressed with how quiet it is. Compared to the Seagate Momentus 160Gb drive I've just swopped out, there's no vibration & hardly any noise!
    I use my MacBook for DJing with, & I just need some information about any anti shock systems that this drive may have.
    Now I know that some drives have shock protection built in, & I also know that the MacBook also has it's own shock protection as well. I'm sure I read somewhere that you can have problems if you have two anti shock systems working on your computer (hitachi's system on the drive, & apple's own sudden motion sensor), & that it's best to disable one of them.
    Does anyone have any info about this at all?

    The only problem I have heard with this is with the Western Digital 250 GB drives. That is why I picked the 320 GB WD. If you don't hear any clicking noise you should be OK. If your still concerned contact Hitachi customer service and ask them if it will be a problem.

  • Sudden motion sensor - hardware malfunction - beach ball lag related

    Hello,
    I have a macbook pro 13" bought in July 2009 with the 160Gb Hitachi 5400 rpm hardrive and 2Gb Ram. I also have the beach ball lag problem and have been reading many posts about it on this and other forums. However, I noticed today that in my System Profiler - Hardware overview, my sudden motion sensor (sms) is indicated as State: Disabled. I look at the state of the sms through the terminal window (sudo pmset -g) and is says sms 1!!! Something is wrong there! Then I executed "sudo dmesg | grep -i error | grep -i sms" to check whether there are any errors about SMS. and I get the following line:
    SMS::checkForInvalidInts ERROR: we appear to have a hardware malfunction
    SMS::setupInts ERROR bad hardware detected, disabling the interrupts
    Then I looked in the Console at the System.log and realized that everytime the beachball lag was occurring, I was getting the same message in the system log:
    Aug 23 17:07:28 localhost kernel[0]: SMS::checkForInvalidInts ERROR: we appear to have a hardware malfunction
    Aug 23 17:07:28 localhost kernel[0]: SMS::setupInts ERROR bad hardware detected, disabling the interrupts
    Although there are many posts on the beach ball lag and on the firmware updates, I don't seem to be able to find any information about this error what it means and how it might be fixed.
    I also tried to test the SMS. When I enable SMS through the terminal command, I hear a click if I move my computer up and down through the air. When I disable SMS through the terminal command, I don't hear the click. So I'm very confused!
    Has anybody got a similar issue with their sms and have they been able to resolve it?
    Thank you very much.
