HT1338 How do I turn of battery recharge when on  a plane (Macbook Pro Retina)?

Hi,
I would like to know how to turn off battery recharge when on a plane.
Every time I plug it in, the power goes down because recharging the battery consumes too much power for the outlet on the Boeing 747.
Previously I would just take the battery out of my laptop. Obvioulsy that is not possible anymore on a MacBook Pro!
Thanks
Christoph

I agree it's an interesting problem, but I believe it is technically possible. The man page for 'pmset' has this tantalasing clue:
Certain Apple battery calibration tools may temporarily disable battery charging, even though your Apple portable is plugged into AC power. Such tools will never surprise you with this behavior; you will know it's happening. This state will be reflected in an additional line of output to 'batt' or 'ps' readings, including the pid of the app inducing this behavior.
         'ChargeInhibit':    1432
Changing the power assertion of 'ChargeInhibit' from 0 to 1 can therefore be done programmatically. However, no Terminal or AppleScript tricks are going to work for this one  - it loooks like it's something that needs to be written in Cocoa.
That leads to two suggestions, both of them a bit woolly I'm afraid:
1. Try asking over on the Apple Developers forum (where the cocoa programmers hang out)
2. Try searching for one of those 'battery calibration tools' mentioned above, or a 3rd party battery management app. I did try a couple of searches, but didn't turn up anything promising. Maybe you'll have better luck.

  • HT1338 How do you get abode flash player to work on a Macbook Pro Retina?

    I have downloaded the latest version of Abode Flash Player but it still does not work on You Tube, do I need to change any settings on my Mac?

    If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test. For a "missing plug-in" error, start with Step 4.
    1. If you're getting a "blocked plug-in" error, then from the menu bar select
     ▹ System Preferences… ▹ Flash Player ▹ Advanced
    and click Check Now. Quit and relaunch your browser.
    2. Triple-click the line below to select it:
    /Library/Internet Plug-Ins
    Right-click or control-click the highlighted text and select
    Services ▹ Open
    from the contextual menu. A folder should open. Delete the following item, or anything with a similar name, if present:
    Flash Player (failing).plugin
    You may be prompted for your login password.
    3. Re-download and reinstall Flash. Download it from this page:
    Adobe - Install Adobe Flash Player
    Never download a Flash update from anywhere else.
    4. If you get a "missing plug-in" error, select
    Safari ▹ Preferences... ▹ Security
    from the Safari menu bar and check the box marked Enable plug-ins.
    5. Select
    Safari ▹ Preferences... ▹ Extensions
    from the Safari menu bar. If any extensions are installed, disable them.
    6. In the Safari preference window, select
    Privacy ▹ Remove All Website Data
    Close the window. Then select
     ▹ System Preferences… ▹ Flash Player ▹ Advanced
    and click Delete All. Close the preference pane.

  • Poor battery life and high temperatures on MacBook Pro Retina 15"

    I'm having never-ending problems with poor battery life and high temperatures on a MacBook Pro Retina 15"
    I took it in for service and they told me it needed a new logic board and replaced it.  When I asked why they were vague about the reasons, they said "it just needed one, it failed some test".  I now have the computer back and it runs the same way it always did.  I bought this laptop because it was supposedly capable of high end video editing in 1080P (or so Apple's website claims) and also photo editing. 
    "The processor, graphics, all-flash architecture, memory, and display in the 15-inch MacBook Pro give you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,3 while the latest quad-core processors on the 15-inch MacBook Pro decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,1 you can even edit four streams of uncompressed 8-bit 1080p HD video, right from the internal storage on your 15-inch MacBook Pro with Retina display.4"
    However, when I'm just browsing the web and emailing it runs quite warm and battery life is quite poor.  Sometimes doing those same activities I would say it gets so warm it's almost uncomfortable to have on your lap and the fans are running fast enough to become noticably noisy.  I'm also driving only one screen at and a time and I heard that the MacBook Pro can supposedly do three screens.
    If actually try to do something like video editing with final cut pro the laptop gets really hot, the fans are on full blast and battery life drops to only an hour or two.  I think when I rendered just a 3 or 4 minute clip once I got less than hour of battery life.  I will have to time again.
    Anyway most people (including the sales guys) are telling me no way this is not normal.  When I play with demos in the store browsing the web they are not getting warm or hot to the touch.  My friend's 2013 MacBook Air is also NOT getting warm to the touch doing the same activities.
    I installed iStat Pro so I could check the temperature and fan speeds.  I'm seeing temperatures of 70+ on the GPU, 85+ on the GPU diode and 65+ on the CPU heatsink along with elvated fan speeds above 5K which becomes noticeably noisy.  I understand that might be normal for the most processor intensive tasks but it really doesn't seem right for just light web browsing and e-mailing.  (I also may have viber and skype open but that shouldn't matter).  CPU usage is usually running between 2-10% as this is all happening to.
    Furthermore, straight from the specs:
    Intel HD Graphics 4000
    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and  automatic graphics switching
    I am assume "GPU" and "GPU diode" are temp measurements on the discrenete NVIDIA video card, especially since MacBook Airs from the same and newer generatio do not have this reading.  Since Apple Claims the graphics "automatically switches" it seems all the harder to believe the GPU is reaching 85+ when in theory it shouldn't even be activated.  I mean, shouldn't the INtel HD Graphics 4000 be capable of simple web browsing and e-mailing?  Especially with only one screen activated (be it it the internal or an external)?
    What should I do here?  When I asked the repair guys "OK well what is the normal operating temp range for the various sensors" they said "Sorry Apple doesn't provide that info". 

    Yes I have.
    Just web browsing and basically doing nothing I'm hear a lot of aduible fans, I'm getting 85C+ on GPU diode, 65+ on cpu heatsink.  I since installed anohter program that shows me not just the CPU heatsink but the cores and the cores are at 90C+.
    Seems like a lot of heat for doing nothing.  Not only that but I have these problems with no external monitor while on battery power too.
    I don't know what to do.  They already replaced the logic board.  Others seem to get advertised battery life out of Apple products and not have products that get **** near hot enough to burn you while just web browsing or watching a movie let alone advertised tasks like Photoshop and Final Cut Pro.

  • How can I turn off battery charging when plugged in to power on a plane?

    Hi,
    is there an app that can turn off battery charging while plugged in?
    I regularly fly from Australia to Europe (22 hours on the plane!) but the power outlet usually stalls when draining too much power
    (e.g. 85 Watts for my Macbook Pro battery).
    Any solutions available?
    I used to just take out the battery, however, that  is not possible anymore on the Macbook Pro.
    Thanks for your help.
    Christoph

    But why turn off battery charging, makes no sense in this case. You either run off the battery or plug it in and run off the battery while it is charging.
    The power draw won't change appreciably.
    My bad power consumption will change
    It would seem the best strategy would be to get on with a fully charged battery plug in the laptop and let it trickle charge as you use it. Given the length of the flight this should give you the longest use with the minimum amount of draw from the seat outlet.

  • How do I turn the fan back on on my 13" Macbook Pro?

    I have a 13" MacBook Pro. For some reason, the fan started running constantly. The fan would audibly turn on within a minute of me starting up my MacBook, and then remain on for the duration of the time that I used the MacBook.  When I would "sleep" the MacBook, the fan would finally turn off within a couple minutes of selecting "sleep."
    Getting tired of the constantly running fan, I messed with some things in the Settings, and the fan went off. I have no idea what it was that caused the fan to turn off.
    Now, no matter how long I'm using my MacBook (sometimes 10 hours at a time), the fan NEVER turns on.
    I'm afraid my MacBook will overheat.  Any ideas on how to get the fan working properly again?
    THANKS!

  • HT1338 How do I install a hp Laserjet P1102w printer to a Macbook Pro with WiFi

    The hp Laserjet printer is plugged into the usb port of an IBM PC running Windows XP.  I would like to leave it thus connected.

    From your post I cannot tell if you know the procedure to add a Windows shared printer to the Mac but are having trouble after doing so, or if you don't know the procedure. So I will reply on the premise that you don't know how to add the shared Windows printer.
    So for starters, the HP would have to be shared on Windows. This will let the Mac see the shared resource on the local network. You also mention WiFi. So this would require the PC and the Mac to be connected to the same WiFi router.
    With the sharing enabled on Windows, on the Mac you open System Preferences > Print & Scan and click the plus button to add. You then select the Windows tab in the Add printer sheet. This presents you with a window that has three columns. The first is the Workgroup, followed by the Computer then the shared printer name. Typically Windows will use Workgroup for the workgroup name. So you should see Workgroup in this first column. When selected, the second column should show the name of your Win XP computer. If you select this computer name, you will then be prompted to authenticate to Windows to continue. At this point, enter your Windows user name and password. With this information correctly entered, the third column will show the shared printer. Select this and then select the supporting driver for this printer in the Use menu. Click Add to complete the queue creation.
    Now with regards to the supporting driver, there are many printer drivers for OS X that cannot be used when a printer is shared by Windows. So if the driver you select on the Mac fails to print then you may have to look at alternative drivers, such as Gutenprint, PrintFab or HPIJS in the case of HP printers. But if this particular HP LaserJet supports the PCL or Postscript printer language, then you can select the Generic PCL or Generic PS that is included with OS X. While these driver do not give you any features for printer, they do at least let you print.
    One last point. After adding the printer, the first time you try to print from the Mac via the Windows shared printer, you will be prompted to authenticate again. So enter the Windows user name and password again, and save this to the Mac Keychain so that you don't have to worry about authenticating the next time you print.

    I just need to know which way you are syncing. If using iCloud, you don't need to sync through iTunes.
    In the info section of the device in iTunes, you have the Contacts checkbox selected, correct?
    Why do you say only Outlook contacts? What happens with the contacts selected and you Sync?

  • How can I remove an EFI firmware password in a 2012 MacBook Pro Retina?

    This computer was bought used. The SSD in it is dead, and it has an EFI firmware password blocking all my boot options. How can I remove it? The closest store is 400 miles away.

    "YOU" CAN'T. You need to take the system to an Apple store or possibly an Apple Authorized repair center and ask them to remove it.
    If you bought it used contact the original owner and ask for the password. Once you know that "YOU" can remove it.
    If you come back with I can't get in touch with the original owner then I have no more help for you. Take it to your nearest Apple store.

    I would find Marcel Bresink's Temperature Monitor more trustworty, as he has just updated the code and explicitly states compatibility with all 2012 models:  http://www.bresink.de/osx/TemperatureMonitor.html
    I have just downloaded the "Marcel Bresink's Temperature Monitor"/
    You are correct, it does give a more accurate reading.
    MSTM = 54 C
    iStat Pro = 70 C
