The whine issue and its dissappearance

so maybe someone can answer this for me. ive read all the forums and am familiar with all the issues. i have a week 13 build 1.83 mbp. it has the whine that goes away with photobooth or the noisekiller. when i boot to xp via bootcamp there is no whine whatsoever. *** is up with this.

Yes.
There was a bug in the Windows XP implementation that lead to this. Microsoft has acknowledged and patched this and users who have done so report that MacBooks now whine under XP with this patch. On the other hand, battery life is now marginally better than it was under XP (previously users were reporting that they experienced about 15 minutes less battery life under Windows than under OS X). I'm not sure what the current state of play is.
So, for those who think that Microsoft has more experience with power management on Intel processors, the real world experience says otherwise. Battery life seems to be longer under OS X.

  • I have a serious (and bizarre!) issue with my novation impulse (Although i've tried it with two other keyboards and i still have the same problem) and its compatibility with mainstage 3

    i have a serious (and bizarre!) issue with my novation impulse (Although i've tried it with two other keyboards and i still have the same problem) and its compatibility with mainstage 3.
    the problem is best explained on the following one - page thread: 
    https://discussions.apple.com/thread/3951518?start=0&tstart=0
    (Clearly i'm not alone in this problem, although i think i figured out what's going wrong a little more than he did...read on!)
    his solution, to put mainstage in jump mode, is very unsatisfactory to me, as it bounces all of a sudden to drastically different settings.
    basically, my analysis is that my controller is NOT receiving MIDI date from mainstage.  in other words, mainstage knows what my controller is doing, but my controller doens't know what mainstage is doing.
     let's say i turn the knob all the way to the right ... 127...and the virtual fader goes to the right like it's supposed to. 
    now...next...let's say i change to a different patch, where that same VIRTUAL fader is not at the max clockwise position..maybe it's only at 1pm.  now when i turn the physical knob to the RIGHT, the midi data is still at 127 on the controller!  it didn't "reset" to sync up with the new level (say 80 or so) setting on the new patch.  so i can't increase that new setting of 80 by continuing to turn the knob to the right.  i have to turn it all the way to zero,...and then continue PAST zero until the controller thinks that IT is at 0...at that point the controller and mainstage are in agreement, and things work fine....so bascially, the keyboard thinks the level is at max...but mainstage thinks the level is at 1pm.
    i am using Logic 9, and i have a macbook pro 2.9 Ghz I7 with 8 gigs of memory and OS X 10.8.4

  • What is it talking apple so long to create an update for the whine issue?

    I think it is pretty ridiculous that the only update apple has released that effects the whine issue, only makes it worse. Even worse is that users over here have managed to detect and resolve the issue before apple has managed to do so. So come on apple, what's taking so long? It's amazing how badly this situation is being handled.

    They know about the whine issue, i just talked to a product specialist who told me that they knew about it.
    He also told me that Apple was not planning on adressing it since the cpu whine was within specifications.
    As i said, it was a product specialist not an engineer so there is still a little hope regarding this issue being fixed sometime in the future.
    I am not the only one to be disappointed about this and other problems that MBPs have.
    But for now i m going to try and enjoy what i have , at the end of the year i will buy a sony loaded with vista since Apple is not able to give me satisfaction.
    I m a loyal Apple customer since many years, but i have had enough, no more repairs or exchanges for me; I wil just be switching back!
    The only thing that could make me change my mind is if Apple recalled my defective computer in order to give me a machine free of problem.
    So far it's impossible since they don't have such a machine in stock.

  • There is a difference between the document total and its components

    Hi!
    I have an error message "There is a difference between the document total and its components" when I want to create an InventoryGenEntry
    the problem arises from time to time and my customer must do the document two or three times before it is created.
    I have seen in this forum and in notes that this is probably being caused by a Rounding.
    I am using 2 digits for amounts, 4 digits for prices, 6 digits for rates and 3 digits for quantities.
    For information my customer use SAP 2005 and the patch level 46.
    This problem happened only in InventoryGenEntry. how can I modifiy parameters to resolve this problem?
    thank you for your help.
    Best Regards
    Séverine

    Hi Séverine,
    Do you find any additional code added to SBO_SP_Transaction stored procedure. A similar issue with stock transfer fixed in later patch. Please test in latest patch.

  • The cause of the whine, heating and short battery life.

    It seems like we've discovered how we could fix the whine, heating and the short battery life.
    If you take a look at /var/log/System.log
    You will find this line:
    localhost configd[37]: com.apple.SystemConfiguration.DynamicPowerStep load failed
    Yes, that's right. Intel SpeedStep is not implemented in Mac OS X.
    It seems like Apple wanted to implement it, either the engineer in charge of it was screwed up or apple was hurrying to get macbook pro released...
    This also explains why Macbook pro has a higher battery life, runs cooler without whine on a properly configured Windows XP (with updated intel drivers and microsoft hotfix). On Windows XP, when the system is Idle, CPU is throttled to 1GHz.
    So we have two options:
    1. Get Apple to implement it correctly - but so far it doesnt seem like apple is really concerned about this issue. Or rather, they don't seem to care.
    2. Implement it ourselves - A guy called Cryptonome was trying to implement the proper power management for MacBook Pros on Mac OS X to solve these "CPU whine", heating and battery life problems, and he did have some fruitful results, but it seems like he's currently too busy or something to finish the implementation.
    Unfortunately I am not a genius so I cannot implement anything like this... anyone?
    What do you guys think?

    That's exactly what I am doing : expecting a solution from Apple. And you know what, Apple today released a new system update for the keyboard. This update is for all the MacTels including MacBook Pro. And guess the next thing... This update fix a power draw in the MacBook USB... Great... Oh, no, in fact not so great because this bug is THE bug that allows to stop the whine (through Mirror, etc)...
    Is there anyone in Apple that tests fixes before to release them ? Do those engineers working on the whine fix have given a look to that patch ? I really hope that Apple is doing something, but releasing this Keyboard patch for MBP now can mean 3 things (IMHO) :
    - the whine patch is on the final steps and will be released soon, so killing the workarounds for the whine is not a problem,
    - or Apple has a partial (or even none) knowledge about this problem, and they should hire better engineers, because many people made a lot of discovers about this whine, not beeing engineers,
    - or Apple definitly doesn't care about this whine problem, and they will loose myself as a customer (and probably others).

  • Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verif

    Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verifying and repairing it but had no luck. I also tried mounting and unmounting it but still no solution. Anyone to help please?

    Looks bad. I would strongly advise backing up the stuff on the other two partitions as soon as possible in case the rest of the drive goes wrong.
    Beyond that, Disk Utility has limited abilities to repair disks, DiskWarrior uses a different approach and might, emphasis might be more successful. It has certainly done the job for me in the past when Disk Utility could not.

  • I just plugged my iphone in to download some pix to my computer and my phone is now showing a plug with the itunes icon and its telling me I have to restore my phone and will lose all my data. *** is going on and how can I go back?

    i just plugged my iphone in to download some pix to my computer and my phone is now showing a plug with the itunes icon and its telling me I have to restore my phone and will lose all my data. *** is going on and how can I go back?

    "I have logged in to my itunes account on a different computer and none of my purchased music is showing up."
    Correct.  it does not magially appear in other places.  It will only be where you put it.
    "I also have plugged my iphone in to get updates but it says I will lose all media and apps if I don't update on the computer where  I sync everything. "
    Correct as well.  Iphone will sync with one computer at a time.  Syncing to another will erase the current content.
    You need to copy everything ( itunes library/contacts/pics/calendars/files/docs) from the old computer, or your backup copy of the old one, to the new one.

  • Even when I charge my Mac Pro to the full bar, the battery seems to be drained even when I am not using it. Example, after charging it full, i switched it on the next day and its 79% battery left. Is there something wrong? help please

    Even when I charge my Mac Pro to the full bar, the battery seems to be drained even when I am not using it. Example, after charging it full, i switched it on the next day and its 79% battery left. Is there something wrong? help please

    Assuming you are disconnecting from line power, when you say switched on, do you mean it was shutdown or in sleep mode?  If sleep mode the battery will still drain because sleep still keeps some things active and the battery does drain a little.  However, to go from 100% to 79% charge overnight is a bit excessive in sleep mode.  Unless you have some processes set to activate over night by the cron file and do things like backup the system.

  • How I can get the Billing Type for the sales order and its items

    How I can get the Billing Type for the sales order and its items. I mean from which SAP tables and how?

    Hi,
    You need to use two tables.
    First use VBFA. Enter the sales order number in the field Predecessar and the value M in SubCt field. This will give all the billing document number for the sales order items.
    Then use the billing document numbers in table VBRK, where in you can get the billing document type.

    Dear,
    you can use FBL1N,
    From there you can view following things:
    1. Vendor Invoice = Reference
    2. Document type = KR and RE for Invoices
    3. Po Number
    4. Amount
    you can enable there many fields as per your requirement.
    Hope this helps!!!
