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?

Do the MBAs with a SSD still have a sudden motion sensor? I was trying to use smack book with my Rev A SSD, but the SMS is either broken or missing, trying to figure out which it is.
I've just installed a Crucial C300 256Gb in my Macbook Pro 17" and replaced the Superdrive with a Seagate 500Gb.
I'd like to disable the SMS for the SSD but keep it for the 2nd HD. Is there anyway to do this?
I believe the following is for all drives at once.
# to disable
sudo pmset -a sms 0
# to enable
sudo pmset -a sms 1
Downloaded iAlertU and it turned out not to work.
I then found no sudden motion sensor present in the system profiler of new macbook air 13. Looks like we miss another quite cool feature.
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'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?
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 put a 1TB Samsung 840 EVO in my MacBook Pro (9,1). Should I disable the sudden motion sensor? Does it do anything else other than park the hard disk (like something with the fans)?

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.
View 1 Replies View RelatedI'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?
View 2 Replies View Relatedi have big problem with Sudden Motion Sensor (SMS) its impossible to deactivate it.
I've used commands from [URL]
Snow Leopard 10.6.2, MBPro 15.4" 2.66 Mid 2009
Always sms has value -1, i cant set it to 0 (turn off)
here is terminal log:
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 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...
Been having this clicking sound on my 13"MBP lately. I was told it might be the motion sensor being too sensitive. Anybody know how to reduce this sensitivity?

2007 MacBook: 2.16 Ghz, 3GB RAM, Intel GMA etc.
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?

View 1 Replies View RelatedAs of today, I noticed my ambient light sensor doesnt seem to work. I tried disabling and re-enabling it in system preferences, but that hasn't done the trick.
Is there some test I can do to see if it's working or not? I know it worked two days ago, because i took the i7 15" MBP outside and it automatically switched to max brightness. Today I took it outside and the brightness didn't switch at all and I couldn't see the screen it was so dark.
Since the last time it definitely worked, all I've done is install Windows 7 64-bit with Boot Camp and hooked up the MBP to an external 20" monitor with a minidisplay-DVI adapter.
I bought my first Mac computer last month, the 13" 2.4 variant. Loving it so far.I have lately noticed however that my ambient light sensor is not much of help. Before, after coming out of sleep I could notice the screen changing to accommodate for the room's light output. I could also put my hand over the sensor near the iSight and witness the brightness decrease in front of me.
Just this morning, I opened my MacBook which had been sleeping overnight. for some strange reason, even when the screen was up, the light at the button was still glowing (indicating it was asleep). I tried forcing it to shutdown. When I turned it on again, it went to sleep mode right when the desktop was about to load. I tried booting from Windows 7 but sure enough, when I reached the login screen, the computer went to sleep. I concluded that it was definitely a sleep sensor problem.

I could just by the replacement fan and swap it out but I am wondering if there is anything else that could be malfunctioning and causing the fan to NOT spin up - anything I can check before forking out the cash.Is there a way to see if the temp sensor is working? Could it be the LB? Can I test the electrical supply to the fan by using a multimeter? If so what setting/voltage, etc should I use to read that? And lastly, is there more than one fan?
View 3 Replies View RelatedMy Macbook Pro keyboard Backlight is not working properly even in a darkroom.
I need to install a third party software (Lab Tick) to switch on the keyboard light.
I am not able to use F5 and F6 key to adjust the light dimness. I suspect the light sensor is having problem.
However, last night I received an error message, saying that my Mac is having problem, I need to press the Power button to restart the Mac.
After restart, the keyboard backlight is working (without Lab Tick), and I can adjust the light with F5 and F6.
But now,after I made the Macbook sleep and wake up, it's back to abnormal again.
Suddenly, and spontaneously, pinch to zoom is not working in any area of Motion. I thought maybe I accidentally did some keyboard thing that disabled it, but System Preferences shows it's still enabled, and pinch to zoom is working normally in all other applications. It's just not working in Motion for some reason. I've restarted Motion and that didn't fix it. Also rebooted and surprisingly that also didn't fix it.
View 1 Replies View RelatedI have a new MacBook (Dec '08) and everything is working fine with one exception. When I type numbers into the calculator app they appear on the screen in slow motion with a nice long pause as each number typed is displayed. On our iMac the calculator app just flies along and has no problem keeping up no matter how fast I enter in numbers. Any ideas where to start on this one? Besides the standard software we have installed Microsoft Office and Handbrake.

View 3 Replies View RelatedI 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?
