Macbook Pro 13" Doesnt Have A Sudden Motion Sensor
Jun 9, 2012
I was looking around the big web recently, and saw liquid mac. I downloaded and installed it on my 2011 13 inch macbook pro but it said it couldnt find a sudden motion sensor. So i checked system information, and it confirmed this... I didnt have a sudden motion sensor. Should i go and get this fixed somehow?? can they fix it or will they replace my laptop? Also, the hdd is factory installed if that makes a difference. I have applecare
I just dropped in a 1 TB drive into my 17" MacBook Pro and it seems like that the Sudden Motion Sensor doesn't work not. I do not hear the sound when it engages as I did with the stock 500 gig drive that was in there. My understanding is that the Sudden Motion Sensor was not built into the drive and it was built into the notebook itself. Shouldn't I still be hearing the drive stop when the Sudden Motion Sensor engages?
I'm installing the Samsung SpinPoint drive tonight and was curious. Does the sudden motion sensor still function properly? The reviews on Newegg don't seem sure. One guy thinks it still works, but he simply no longer hears it, and another is convinced that without the clicking sound that comes with moving the MBP, it's simply not functioning.
My new MacBook Pro's "Sudden Motion Sensor" won't seem to enable. I've done the Terminal commands listed on Apple's support page and I get a "1" instead of a "0" next to the results, implying that the system thinks it's turned on, yet under "System Profiler" it says "Disabled."
I'm not sure if this would influence it but, I do have a WD500GB Scorpio Blue drive inside and was suffering from the "Beach ball of death" issues associated with the 3rd party HDD's, so I downgraded from the 1.7 EFI Firmware to the 1.6. Anyone experienced this issue or have any recommendations?
Some hard drives have a motion sensor in them. These are NOT supposed to be in MacBook/Pro's as the Macs have its own Sudden Motion Sensor. If your MBP has both, they could be conflicting with each other. Try this simple test to see if the problem goes away: (if you're not adventurous, don't proceed)
<<To disable the Sudden Motion Sensor:
Find the current status of Sudden Motion Sensor:
(log in as administrator)
1. From the Finder's Go menu, choose Utilities. 2. In the Utilities folder, open Terminal. 3. When the command line appears, type sudo pmset -g and press Return. 4. 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). 0 means off.
Disabling the Sudden Motion Sensor in Mac OS X 10.4 and 10.5:
1. In Terminal, which should still be open from the previous step, you can disable the Sudden Motion Sensor by typing sudo pmset -a sms 0 and pressing Return (changing the setting to a zero disables the module). 2. Type your administrator password when you are prompted and press Return. 3. Type the sudo pmset -g command again to be sure that the setting has been applied.
Any changes that you make to the Sudden Motion Sensor setting remain in effect even after you restart the computer. If you choose to disable the Sudden Motion Sensor, Apple recommends that you re-enable it as soon as possible in order to take full advantage of the feature.
To re-enable the Sudden Motion Sensor:
Find the current status of Sudden Motion Sensor:
1. From the Finder's Go menu, choose Utilities. 2. In the Utilities folder, open Terminal. 3. When the command line appears, type sudo pmset -g and press Return. Type your administrator password when you are prompted and press Return. If you have the Sudden Motion Sensor turned off, the value of the ams entry (in Mac OS X 10.3) or sms entry (in Mac OS X 10.4 and 10.5) will be a zero (0). >>
What are some good hard drives that have a freefall/sudden motion sensor in them? Planning on putting it in the optical drive bay. I am aware of the scorpio black, but I am wanting something with a bit more storage.
I'm going to have to pop a larger hard drive in this Macbook (2007) to buy a little time before I replace the computer. Does anyone know if my Macbook's sudden motion sensor can work with *any* replacement hard drive to tell that drive to park its heads in the event of a drop? Or does that only work with certain ones?
I think this post would fit in the Hardware/Notebook-section as well but since I am looking for a OSX workaround, I will post it here:
I have a problem with the sudden motion function in my PowerBook. When switched on, the SMS causes to switch off the internal hard-drive at random, even if the Laptop stands on a perfectly still and flat surface. This results in interruptions that make it impossible to work with the computer.
I already had this problem when I was running Panther (10.3.9), and deactivated the SMS with the "pmset"-command using the Terminal at the time. As long as I was running Panther, this workaround worked perfectly for me, I had no more hard-drive-interruptions.
Later, however, I made the Upgrade to Leopard (I skipped Tiger), making a clean install after formatting the PowerBooks hard-drive. Now the SMS was active again (and displayed "active" in the System Profiler) and the HD-interruptions were back.
So I tried to deactivate the SMS with the "pmset"-command - this time without result. I can set the value of "sms" to 0 and back to 1 all right - the Terminal shows the corresponding value when prompting "pmset -g".
Unfortunately this has no effect to either the hardware (the interruptions are still there) or the System Profiler (is displays "active" for the sms, regardless of the value that is shown when using "pmset -g"). I am aware that the variable was altered from "ams" to "sms" from Panther to Tiger (and subsequently Leopard), but neither "pmset -a ams 0" nor "pmset -a sms 0" would work.
To exclude the possibility of a real hard-drive-malfunction, I bootet the Powerbook from an external Firewire-Drive an with my an Panther-backup. After making some testing with accessing the internal HD (it worked fine), I looked into Panther's System Profiler and saw that the SMS was deactivated as expected.
I then experienced something strange - when rebooting Leopard, the sms-Status in the Profiler still was "inactive" and the PowerBook worked perfectly again. I was quite happy and made some updates. However, somehow the status was set to "active" again after some reboots, along with the malfunctions experienced before.
I wanted to find out, whether this "reactivation" had something to do with one of the updates (I brought the system up to 10.5.5 at the time) and booted the old Panther again. The sms was inactive again, again remainded inactive after reboot with Leopard.
I tried to reboot with and without power plug, I even made a PMU reset - the SMS remained inactive (which was good and made me hopeful again). However, after I switched of the Notebook and bootet again a few hours later, the sms-Setting in the Profiler was "active" and the Notebook was again not working properly.
Is there any possibility to access the sms-setting apart from "pmset" in the Terminal? Where does the system profiler derive the status from?
I want to deactivate the sms for good and at the moment this apparently works only in Panther (and I really don't want to downgrade to 10.3 again). I don't want to have it repaired since I think this would mean to replace the Logic Board which is a much too expensive investment for a 4.5-year-old Notebook.
I have bought a macbook pro in the late 2009.. and its sudden motion sensor is repositioned (in version 5.3) and it works in the other way around.. when i try with programs that use the sensor to make sth.. like when you move right, the things going upwards.. and when you move in the y direction things are moving in the x direction.. So has anybody have this problem?
And i have been reading articles about new version Smackbooks which works with this version but nothing was helpful so far.. I am calling those people who have the same version as me and have some proper apps to work with our version...
I have ordered several new MBPs (5 with SSDs...) for my clients, but have a mechanical HDD for myself in my new MBP; I just thought about the motion sensor that locks mechanical HDD read heads on sudden acceleration, and realized that it is an OS feature... Has anyone that has a mid 2010 MBP and a SSD noticed HDD lock in sudden movement with a SSD?
You can simulate this 'lock' by moving the MacBook suddenly when playing content from the drive... Has anyone seen the drive cause playback to halt for 2-3 seconds while the SSD 'recovers'? If so, this needs to be fixed...
Anyway, all of sudden, any motion I make kills the backlight of the screen. In the right light you can still see things and the computer still works perfectly, just extremely hard to see. Have to do a restart in order to get going again.
I replaced the hd in my 13" macbook pro with a western digital blue, 500gb. My concern is that the computer is not as snappy as I think it should be. I understand that I might have installed a hard drive with a motion sensor and that the motion sensor of the hd may conflict with the motion sensor of the mac itself and that might be the source of the slowdown? If so, which sensor should I deactivate, the mac's of the hard drive's?
i need a software that enables me to change the song by hitting the macbook. I want it to use the inbuilt motion sensor.. I had a software for virtual desktop..which would help me to change the desktop by hitting the macbook (not a wild one)... please let me knw if there is such app..

"You need to restart your computer. Hold down the power button for several seconds or press the Restart button."
I get this message everytime I turn on my MacBook Air and cannot get past it.
When i turn the power off, it hang for quite a long time and this screen appears,
Macbook Air OS x 10.5.
Before this happened, i went on skype and firefox. But then it hanged, so i had to hold the power button to shut it down. I meant to restart it back but then i couldnt. This problem appears.
Just before it happened, i dont have any start up application. But before, they were adium, skype and transmission. And my 'HUAWEI mobile connect broadband internet' connect automatically. and i dont use time machine.
this is my third macbook pro and the headphone jack doesnt seem to be as 'tight' as the other ones I have owned. The headphone jack goes into the socket with minimal pressure but I do hear a click. While the other I owned I had to apply a little bit of pressure.
Ive got my MBpro since May. The first thing is noticed is when the computer is using or charging the battery, that the left side gets hot and feels different then the right side. on the edges. Someone has this to? I have it on my 13'' aswell
Just wondering if someone could please help me. My Macbook wont turn on, when I connect the charger to the Macbook, a faded green light appears on the charger (not as bright as it usually is) but still the Mac will not turn on. I have tried someone else's charger and the light on that charger also went a faded green colour. So i believe it is something to do with the Macbook and not the charger.
My university has a Wifi all other the grounds but i can only use it occasionally with my macbook for some reason. It sometimes loads things like google reader or google searches but i cant look at google images or anything. Everyone else just loads safari or the equivalent and enters an email address and they can browse. Mine does that but then stops and starts working every so often.
I know the MBP has the motion sensor, im pretty sure this is built into the computer correct? and I know the stock hard drive had the option(cant quite remember but it had something to do with the motion) Does that option mean the HDD has the capability to stop due to motion using the MBP motion sensor or does the HDD have its own sensor?
nyone know why why the isight doesnt work eventhough the green light goes on everytym i sue an application using isight. when i open the photobooth all i see is black screen on the photobooth, still the camera light goes on. it was fine at first but aftr not using it for a while..it just doesnt work.
