Sudden Motion sensor active in Boot Camp using Win7 with lid closed

My quesrtion to the community is:
W/ an i7 MBP,
faster 500Gb drive,
running Windows 7 via Boot Camp,
OS running,
Is the Sudden Motion Sensor operational when the lid is closed with Win7 running?

Thunderbolt display problems using MBP with lid closed

I am experiencing a very reproducible problem since purchasing aThunderbolt display to use with a recent (1 month old) Macbook Pro 13"2.7GHz i7.
I use my MBP with lid closed with myThunderbolt display. If Ithen allow the MBP to sleep and power down, on restarting it the WiFi hasstopped working- the menu bar says I am connected by WiFi but Safari will notconnect to the internet and Time Machine cannot connect to the Airport/TimeCapsule to backup. Nothing I do will fix it (shutting down all programs, turingWiFi off then on) and so I have to shutdown/reboot BUT THEN the MBP freezesduring shutdown (waiting 15, 20, 30 minutes!) and I have to hold down the powerbutton (hard reboot). Once I reboot everything works fine UNTIL I take a breakand the computer goes to sleep again.
Doesn't seem to be a problem with the MBP lid open, but I needto test this a bit more to be sure...
On top of this the Bluetooth trackpad now keeps going on andoff; connected, not connected despite being near or the computer. Veryirritating at best, unusable at worst. This only started to be a major problem(every 10-15 minutes or so) when I started to use the Thunderbolt display.
These problems seems to be in some ways similar to anotherthread:
https://discussions.apple.com/message/16205098#16205098
("Major problemswith Thunderbolt display & MBAir")
I have applied the recent Thunderbolt Firmware update, and SMC& PRAM/NVRAM resets. Interestingly these seemed to work initially but thenafter a prolonged power-down period the problem has recurred. Back to square 1.
Any ideas out there?

Just to be clear, have you installed everything that you find on this page?

I just talked to Apple Care about Thunderbolt issues in general and even though I already had the Thunderbolt Software Update installed, he had me reinstall it. If you go to this page:
https://discussions.apple.com/message/16889000#16889000
you can read in detail about the issues I was having which have for the most part been remedied (for now at least!)
The Thunderbolt cable definitely transfers heat for some reason even when there isn't a high CPU utilization. The process 'kernel_task' seems to be where the API for thunderbolt is running. But for some reason, the behavior of CPU Utilization to Fan Speed is amplified when connected to the TBD.
Apple Care is researching it.

I REALLY need to use MB with lid closed...

Sleepless doesn't work after the upgrade, does anyone know of ANYTHING that will work right with this new update? I'm not using external keyboard/mouse btw.. thanks!!

Are you trying this when the Mac is in motion, i.e., in your backpack? If you move the machine much when it is awake, you risk killing your harddrive. If you are trying this with the Macbook on a desk, just leave it open.
Leaving laptops (eps. Macs) on and closed keeps heat from espcaping the way it is supposed to, possibly damaging your system. Apple designed their machines to sleep when shut for a reason.
Just go buy a Nano.

Using MPB with lid closed?

I'd like to use my MBP 13" for iTunes that powers my remote speakers and airTunes etc.
Thing is, I'd like to be able to close the lid and leave it going (my charger is in my AV cabinet which the MBP only fits in when closed), whereas currently whenever I close the lid the MBP goes to sleep and all the music stops.
I've read on these forums about Clamshell mode? But I can't find any more information about how to set it up?
Many thanks,
Dan.

Your MBP is not an iPod, and it will be in serious danger of overheating if you pack it away in an enclosed space (especially an enclosed space that contains other heat-producing equipment) while it's running. If you insist on doing so anyway, you'll need the aid of a third-party hack that prevents sleep, such as Caffeine or InsomniaX. I don't recommend this at all.
Instructions for using your MBP in clamshell mode (which won't accomplish what you want) are here:

Safe to use MacBook with lid closed?

So my MacBook (early 2009) was in sleep mode when I put it on my desk, plugged it in, then plugged in my monitor. The monitor turned on and my desktop appeared, with the menu bar and dock on it. When I normally use a monitor with my MB, the MN screen is my main screen. Obviously it woke up when I plugged in the monitor and USB mouse. My question is, can I use it like this all the time? I prefer to use the external monitor as much as possible, and being able to close the MB lid when it's on my desk would save a lot of room.

Here is the link to what Lyssa mentioned...

Sudden Motion Sensor - Anyone else hearing it?

Recently got a new 15" Macbook Pro with the 320gb 7200 rpm hard drive.
Something that's a bit worrying is that I can hear the sudden motion sensor activating. In my previous MBP, which is about 2 years old, I couldn't hear it activate at all.
Also, I've got the new MBP on a stand to raise it up. However almost every time I knock the desk it's on, the SMS activates. Sometimes it doesn't need much force to activate at all.
I'm wondering if this is likely to decrease the life of the hard drive as it's parking the head unnecessarily so often?
Thanks
Chris

My MacBook Pro's Hitachi 320GB 7200 rpm drive also clicks when it parks. I don't worry about it. Hitachi's web site claims a MTBF of 600,000 load/unload cycles (or over 160 load/unload cycles per day, every day, for 10 years).
The noise itself doesn't bug me at all - my old G4 powerbook used to cycle the optical drive every time it woke up, but it never failed (4.5 years of near daily use). So a servo or some do-hicky clicks when it does what it's supposed to do?
If it fails, I'll have AppleCare replace the drive for me, and I'll simply restore from my TimeMachine backup or from one of my SuperDuper clones. I'd rather have the motion sensor parking the drives when the machine moves then NOT doing so and having a HD head crash when I carry the machine from one room to another.

Cannot see status of sudden motion sensor ( imac 5,1 )

Im using logic 9 and ive fitted a new hard drive to my imac i keep getting a warning notice in logic that the sudden motion sensor may be parked however when i open terminal to try and determine the status of the sensor eg: to turn it off i cannot see the sms status option so i do not know if the sensor is on or even if i have one at all. can anybody help me with this thanks.

iMacs don't have a Sudden Motion Sensor.
Apple uses a Sudden Motion Sensor only in their portable Macs Apple Portables: About the Sudden Motion Sensor and Apple Portables: Advanced tips for Sudden Motion Sensor
Plus 3.5" harddisks used/fitted in an iMac don't have Sudden Motion Sensors to my knowledge.
To be sure check the product details of the harddisk you fitted in your iMac.

Sudden motion sensor is not showing up on terminal. how do I switch it off on my imac

I have an imac with os 10.9.2 and logic pro 9.1.8 .. i am getting a sudden motion sensor error for a very small track with 4 plugins.. this error never shows up on FCP or any other heavy duty software. So I wanted to switch the sudden motion off but can't find it in the terminal while typing sudo pmset -g .. so how do i find it and how do i switch it off.

Hi
In that case you are going to have to give us some more information:
Just one project or all projects?
Does it still do it if you bypass all the plugins?
What buffer size are you running at?
If audio tracks, are you recording/playing back from the System Drive?
What Sample rate/bit depth?

Have you notice whether or not the motion sensor
works?
Apparently not (tested with iAlertU for example and with the software from http://www.kernelthread.com/software/ams/ams.html).
Yeah I'd probably take juhs10's advice and give Apple
a call if it's not working. It's a strange
occurrence. I would assume it's a software problem
but I'm not familiar enough with it to say for sure.
Thank you, I'll call Apple tomorrow to see with them.
Thank you for your help,
Gilles.

Sudden Motion Sensor not working after upgrade to WD5000BEKT HDD

Hi everyone, I just upgraded the hard drive on my Macbook Pro (2010) and I am very pleased with the performance of this 7200rpm drive, I have seen reads around 105MB/s and a pretty good boot time at 23s. But I used to be able to hear the hard drive stop when I moved the computer around before due to the Sudden Motion Sensor technology and since I have the new hard drive in it doesn't seem to work anymore. I have tried switching SMS off and on and it didn't change anything, also the drive is a Western Digital Scorpio Black without Free Fall sensor (I took that version on purpose so it wouldn't conflict with the SMS). Do you have any ideas on how to make it work again? Because I really like this feature on my Mac (I have dropped a laptop before so just in case it happens again). Thanks a lot for your help.
Scott

For future reference, here are a couple of kb articles on the sudden motion sensor:
http://support.apple.com/kb/HT1935
http://support.apple.com/kb/HT1934
As has been said, Apple's Sudden Motion Sensor is not actually built into the hard drive. In fact, some hard drives with their own version of a sudden motion sensor like Seagate's G-Force Protection actually will set up a conflict with Apple's Sudden Motion Sensor.
I installed the same WD in my Mac as you did, and I hope you enjoy it as much as I have been enjoying mine.

Where is Sudden Motion Sensor data stored?

Background:
I replaced my superdrive with an optibay + ssd (OS is stored here) and I left the stock HD (home folder) in it's place.
Problem:
I guess I triggered the SMS the other day and now I can't access my HD (basically just hangs / takes forever to load anything) unless I disable SMS. Where would I clear the data / tell it that my HD is safe to use again. Restarted pram and reinstalled OS, but it didn't help.

Thanks for the responses. Yes, as JoeyR stated, I replaced my superdrive with an SSD and the hard drive is in it's original place so I wanted to re-enable the sudden motion sensor. Thank you for clarifying how the SMS works. I wasn't sure if there was a state that was saved somewhere.
Well the original issue was that my OS would boot (SSD), but I couldn't get into my login (HD). I have a temporary user on the SSD so I was able to use that to troubleshoot. I swapped my HD with another one and it worked (STOCK HD). Then I tried putting the HD into an external closure and that worked as well. I had a feeling it was the connector, but I did not have spare parts to test this theory. I would swap the HDs back and forth and sometimes it would work and sometimes it wouldn't. It was a hit or miss situation. It worked when I disabled the SMS, but when I enabled / disabled it again it didn't work. Ran diagnostics on the HDs, both drives seem fine and in perfect condition. Tried to format the hard drivers and do various combinations of swapping drives and in the end the problem still persisted so it had to be a connector issue. I brought it into repair and they replaced the SATA cable for me and all is good now.
Thanks for the help.

SSD SMS?? (Solid State Drive Sudden Motion Sensor)

Just a quick question, can anyone tell me if the SSD option has a sudden motion sensor? I realize the benefits to hard drive health wouldn't be needed in a SSD but I find it extremely useful for security (ie: iAlertU).
Thanks!
SAM

Yes it does. This is from my SSD model:

Sudden Motion Sensor crash in MBP with SSD

Hi. I replaced my 2011 17" MBP's internal HD with one, then another SSD from OWC, going from 240 to 480.
As indicated in OWC's instructions, the Sudden Motion Sensor no longer applies and should be disabled with this command from the terminal:
$ sudo pmset -a sms 0
And using this command, we can see that the SMS is off:
$ sudo pmset -g
Active Profiles:
Battery Power                    -1
AC Power                    -1*
Currently in use:
womp                    1
halfdim          1
sms                    0
What happens all too often though is that my Mac issues an SMS crash while asleep if I am driving home and hit a bump in my car. Just Monday, I was driving with my Mac open and on, the car hit a bump and I got to watch the Gray Screen of Death as the Mac issued a kernel panic from the Sudden Motion Sensor.
But it's off.
FYI, I turned it off to try and stop this behaviour

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.

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.
