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?
View 7 RepliesI 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...

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.
My friend is stuck on this drive .
But he asked me to find out if it had the G sensor or not. Obviously Macs have there own sensor so he wants to get one without the sensor so it doesnt interfere.
I currently have the seagate 7200.4 500gb but i noticed my load cycle count is already at 8000 after only 3 weeks of use. So I think Im going with the hitachi 7k500. if this has the g sensor built in? if so does this interfere with my macbooks g sensor?
View 7 Replies View RelatedI'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
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 then found no sudden motion sensor present in the system profiler of new macbook air 13. Looks like we miss another quite cool feature.

View 10 Replies View RelatedSince Apple has started putting these water sensors on almost all of their devices now, I am pretty sure that the unibody MBPs have them too (on portions exposed to the external environment; not just on the logic board and internal chasis).
I was wondering if anyone knew where they were located out of curiosity.
I've been using my mum's MPB C2D quite a bit, in anticipation of my own i5 arriving, and one thing that gets on my nerves is the ambient light sensor. It seems to be really sensitive, to the point where it will change the screen brightness when there has been no real changes in ambient light. If you move your hand over the sensor at the top of the screen, or even if someone walks past and casts a shadow it can change for a few seconds. Also, just moving the laptop around and the sensor changes the screen.
Obviously this setting can be turned off, but I'd like the feature if it wasn't so sensitive. Other than that, I love the MBP and can't wait for mine!
As 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.
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?

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.
As I'm about to purchase my 2009 MBP unibody I want to upgrade the HDD myself as I've posted before on however will either of the WD scorpio black models work? it comes with or without the freefall sensor? will either be compatible? I read on some retail sites that one won't work with the computer.

View 2 Replies View RelatedMy 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?
Here's a new one (for me anyway).

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 just replaced the bezel on my girl's MBP, pre-unibody, A1260 LED backlit display, and it no longer senses that the lid is closed and goes to sleep. Does anyone know where this sensor is?

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 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)?

I've noticed that the ambient light sensor in the MBP can be somewhat sensitive. Sometimes an action as simple as moving my hands up to the keyboard (from the side) triggers the "auto-dimming" feature of the screen and it slightly reduces the brightness of the screen, then quickly returns. This is rather bothersome.
I've got the option under Keyboard and Mouse "Illuminate keyboard under low-light conditions" unchecked, but the screen still dims if you cover the speakers. I've also got the option under Energy Saver "Automatically reduce the brightness of the display before sleep" unchecked as well.
I'm at a loss here. Is there not a way to disable this auto-dim feature? A Google search didn't turn up much of anything. Surely there must be a way...
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). >>
i plan on upgrading my macbook pro 13" to a scorpio black. Should i get the version with or without the freefall sensor. I heard the sensor conflicts with the sensor built into the macbook pro and causes kernel panics.
View 2 Replies View RelatedSo I've recently purchased the new 13" MBP, and to my understanding, there is a light sensor that turns up the brightness of the backlit keyboard and screen when in dark environments.
However, the problem with my MBP is that when I turn on the lights in my room, the screen brightness and backlit keyboard both turn brighter, and when I turn off the lights, the screen and keyboard grow dimmer, which is exactly the opposite of what is supposed to happen.
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.
