OS X :: Deactivate PowerBook Sudden Motion Sensor In 10.5

Nov 11, 2008

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.

MacBook Pro :: Seagate Drive Stops And Freezes Computer / Seagate 7200RPM 500Gb

I think I have a slight issue with my 7200rpm 500gb seagate drive. Once or twice every hour it seems to stop and start up again. Kinda klicks. It causes my computer to freeze for about 3 seconds. Whats causing it? Is it faulty? I should also mention that it didn't do this when i first got it. This is the model without the SMS.

MacBook Pro :: How To Deactivate Faces In Iphoto

Apr 9, 2012

I definitely need to get rid of "Faces" in iPhoto. I don't need it and it is making me crazy. It shows up when I am looking at my photos at places (like on the ground, sky, etc.) where there is simply no face. AND if there is a face I don't want to see any names or pop ups from "Faces" on my photos.

It seems Apple again know better what their customers want and decided for them to have this stupid feature! It makes me really sick!

In case there should be no solution to get rid or "faces" I will just use another software and forget iPhoto.

MacBook Pro :: Does The HDD Have Its Own Sensor?

Sep 14, 2010

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?

MacBook Pro :: MBP Motion Sensor For SSD?

Apr 29, 2010

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...

Mac Pro :: How To Deactivate One Of Two Displays Under OS X

Oct 15, 2010

First, I need to say that, regarding my problem, I wasn't sure if I should post in this section or in the 'MacOSX' one, but like I'm facing this problem on my Mac Pro 4,1. So, I have a 8-core Mac Pro 4,1 with an Apple HD4870 to which are connected 2 screens: The main one is a Dell U2410 (1920x1200, via mDP to DP adapter) that I use under OSX for photography retouching with DxO. The other one is a 27'' (1920x1080, DVI) I only use for gaming under bootcamp.

When under bootcamp, I only need to turn off the Dell and the desktop is resized for only 1 display. My problem is that, under OsX, even when the 27'' is turned off, the desktop is extended to this display, I can't find a way to deactivate the 27''. I can't even set the displays as 'mirrors', as they have different heigts in pixels (1200 vs 1080), and then I get a Dell resized to 1080. The only solution I have right now is to disconnect the DVI cable of the 27'' when using the computer under OsX.

OS X :: "force Eject" Or Force Anything Accessing Time Machine Volume To Shut Down

Mar 5, 2009

My Time Machine drive is a USB hard disk, and when I plug it in, I am unable to get it to eject (even if the Time Machine preferences show that I am NOT backing the disk up). When I unplug it, I get the warning message about not unplugging drives before ejecting. Is is there a way for me to "force eject" or force anything accessing my time machine volume to shut down, so that I can properly eject it?

MacBook Pro :: Sudden Motion Sensor With 2 HDs?

Jun 7, 2010

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

OS X V10.7 Lion :: Cannot Deactivate The Resume

Mar 27, 2012

I have two annoying issues and hopefully one of you can help. i have looked around and cannot find an answer to my question, especially my second one (which i think is connected to the first one). I am using Safari 5.1.3 and OS X 10.7.3. One of the accounts works perfectly, the other has two issues:

1 - Safari will always start with the same set of old windows, even closing some of them and then reopening safari will always get us to the same old set of windows. I understand the (new) standard behavior is that if i open windows A, B and C and then quit Safari, at reopening it will open the same windows A, B, and C. If i now proceed to close window (or tab) C and then quit Safari at the next opening i shouldbe presented with A and B only. This is not the case for me, i am presented still with A, B, and C. I can add to the windows but not subtract. Clearly something is wrong here. Thoughts?

2 - Trying to debug problem 1 i decided to close all the winodws in Safari, then in System Preferences-General uncheck the "Restore windows when ..." and so i hoped that closing Safari and reopening would get me to just the homepage, but this was not the case and i was presented with the same old set of windows. This is easily explained by the fact that under system prefs-general the box i had unchecked was still checked. It lets me uncheck it but does not retain it.... I obviously tried rebooting to no avail.

Mac Pro, Mac OS X (10.7.3)

MacBook Pro :: Sudden Motion Sensor Not Working?

Sep 19, 2010

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?

MacBook Pro :: Finding Water Sensor Locations?

Jan 20, 2010

Since 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.

MacBook Pro :: Ambient Light Sensor Is Too Sensitive?

May 12, 2010

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!

MacBook Pro :: Ambient Light Sensor Not Working?

May 16, 2010

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.

MacBook Pro :: Brightness Sensor Not Working Properly

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.

Applications :: How To Deactivate Photoshop Elements 6

Aug 3, 2008

How to deactivate Photoshop Elements 6 for Mac? I want to uninstall PSE 6 but the uninstaller tells me to deactivate PSE 6 first. However, there seems to be no option for deactivation in the applications installed with PSE 6 (i.e. PSE 6 for Mac itself, Bridge CS3, Stock Photos CS3, Adobe Help Viewer 1.1). I have tried to search the web and Adobe's knowledge base... with no luck. Search in PSE 6's internal Help returns one result for 'deactivate' - but it's something about editing pictures. There's no 'Deactivate...' under Help menu.
