Macbook pro for a long period using

Hi guys,.

I worked with my laptop for a long time in daily life, for example from 09:00 until 21:00.

I have 2 question on screen and battery.

Can I use macbook when it is plugged in power or not?

I have an external display and it is connected to my macbook, so I can decrease the brightness up to main display empty, don't you think that it will help me for the use of macbook in the best quality?

If anyone has any experience like those please help me.

Thank you.

External power supply can be plugged in most of the time... mine is.  Cannot overload unless the magsafe circuitry breaks.  Just use it on battery power up to 30% once or twice a month.

Brightness on internal display 0 records the burn-in screen... should not be a problem.  You could be full-light all day and yet it takes years before the internal display has problems.

    I'm considering buying a MacBook Pro 15 inch. I use programs such as Stata, for big calculations. What is my best option?

    Either of the 15 "MBPr come with 16 GB of RAM and because it appears that RAM is paramount for Stata then one of them should be able to manage it.

    Is the portability of paramount importance for you? If this isn't the case, you might consider an iMac. You get more for your money from a laptop to a desktop computer. In addition, the RAM on the iMac can be improved if need more later. From what I've read on Stata resembling an important consideration.

  • Error: "Windows could not update the configuration to start the computer. Installation cannot move forward"during the installation of Windows 8 64-bit OEM System Builder on Macbook Pro for help using Boot Camp

    Hello

    I have a brand new Macbook pro and I bought the OEM System Builder of 64-bit Windows 8 driver in a store. My problem is that I have not only not able to install it using Boot Camp. At the end of the installation, a message appears with the following text "Windows could not update the configuration to start the computer. Installation cannot continue.

    I'm not really a tech guy but I also tried to download virtual box and the same error comes back.

    Can someone help me please?

    Thank you!

    Original title: Windows 8 64-bit English OEM System Builder

    The thread is old now, but it is for those who always have this problem.

    When I got the error, I cancelled and restarted the machine. I pressed the 'option' button when starting upwards and he grew the boot partitions. You should see a 'EFI Boot' partition. Choose that and you restart the installation process, but this time it works.

    Supposedly the boot EFI and WinInstall partition should do the same thing. Manually, select one or the other.

  • In Adobe Acrobat 9, which I used for a long period (widows, 7) said, you can't use this prod

    In Adobe Acrobat 9 (Windows 7) that I use for a long time now it says that I can not use withoutv repair.  He tells me to uninstall it and reinstall...

    I have not run this again with my AA9 and Win7, but were able to see messages on the subject. I would like to try a repair before I do an uninstall and reinstall. You could also disable javascript a bit where there has been little of javascript that caused problems (ok, making wild guesses). If you decide to uninstall, make sure to first disable, uninstall, run http://labs.adobe.com/downloads/acrobatcleaner.htmland remove any left over parts of the Acrobat folder. Then proceed to the relocation and updates.

    There is a question about whether being able to use it is correct, or you just found some message is spam which somehow entered into your system (again, possible a javascript problem). Not to mention that disabling javascript, you can also try to isolate javascripts by moving them to a temporary directory and see if it is at the origin of the problem.

  • Help, please! 17 "Macbook Pro - USB no longer works

    I have a Macbook Pro 17 "2010 edition and I am facing a strange problem which is really harmful to me.  I'm a DJ and use this machine for the job, and she was miss you.

    In other words - when I plug an 85w adapter this Macbook, I have a noise in my helmet and my USB ports stop working intermittently.  It causes my controller DJ disappear and reappear constantly in the sound settings in system preferences and makes it so I can't play and music.  If I unplug the adapter 85w, however, everything works fine and I get no sound in my headphones.  I called my local stores and they have never seen this problem, with a store saying that it will need a new controller for a $500 card.

    Can someone please give me some clue as to what I could do to fix this?  I tried to reset the SMC but no dice.

    Have you tested your power on another Mac adapter or tried a different power adapter on your MBP?

    Ciao.

    Addendum: Perform a Test of Apple hardware. It may give a clue:

  • No entry just wiped MacBook Pro for resale, sign on reboot.

    I recently crossed the steps online to sell my MacBook Pro 2012. It took 11 hours I chose the safest option to have no problem for the customer who purchases thereafter. However, I went through to make sure everything has been deleted, but was met with a grayish no entry sign. I tried restarting and using the keyboard but no luck.

    Any help would be much appreciated.

    No entry sign is no indication that the Mac cannot find an operating system.

    Make sure you have an Internet connect and restart Recovery online (Command + Option + R). You should see a rotating globe and it will take a few minutes (~ 5) to start the Apple servers and their HD recovery. Once the completed progress bar, you should see the OS X Utilities menu. From there, you can use disk utility to erase your Macintosh HD, and then close THE and select reinstall OS X in the menu selections. This will reinstall the latest version of Mac OS X that was preinstalled on your Mac. When the installation is complete and you are in the configuration screen, power off your Mac and it will be ready for the next user.

  • Update of the MacBook Pro for iPad Pro?

    I'm looking to replace my MacBook Pro (MBP) for a new iPad Pro. Apart from the obvious differences that exist between operating systems, i.e. OSX El Capitan vs iOS (9)

    Are there specific functions or tasks that cannot be performed on an iPad Pro, which can be done on the MBP?

    When it comes to streaming music (Spotify) and video (Youtube, Netflix, Amazon, BBC iplayer etc), will all these without downloading additional software, Flash drives or iOS apps for the iPad?

    Any constructive comments will be greatly appreciated.

    Thank you

    Most OS X applications with versions of iOS will have reduced functionality located in iOS (for example. (Pages, Numbers, MS Office applications).  iOS is now supported split screen for some applications (not all), but it offers no true multitasking. iOS supports NO FLASH - never has and probably never will be.  Some 3rd party browsers or proxy subscription services offer alternatives to that, but it's not exactly a replacement for FLASH native.  It's the same for Java applications.

    iOS is not addressable accessible file system or cross-app of the user, as OS X.  iOS apps are sandboxed to sand and largely unable to interact with eachother or every-other data.

    Honestly, even though I love my iPad Pro and use every day for staff and job tasks, it is NOT a true replacement for a desktop computer / laptop.  If your use is very specifically limited to certain iOS apps or certain types of applications that are very conducive to a tablet OS, you should be fine with just an iPad, but if not, you will find you want always a laptop or desktop computer, at least for certain tasks or the types of applications.

    Please also note, that iOS devices, like any electronic mass storage, must be saved if you care about your data at all.  Without a computer, your only backup option is to iCloud online backups.  Solutions available iCloud for photography, however, NO do not replace true or complete for archiving your photos elsewhere for guard - should photo be archived elsewhere (computer, another Cloud Computing service) regardless of your choice of iCloud photo service (s).  A computer is a perfect solution for a backup of redundant iOS device using iTunes and iCloud for backups.  A computer is also required to restore an iOS device in the case of a corrupt system, update, install or some other potential recoverable occsionally disaster.

  • How can I solve very slow scrolling with the mouse when you press the command key? (MacBook Pro, Lion, no problem when using trackpad, no problem with other web browsers, other mice have the same problem)

    Scrolling speed is fine, but when you press the command key and then it becomes very slow.

    He does it with a mouse, but not with the trackpad.
    It does when the modules are disabled.
    No problem on Safari or Chrome.
    No problem on PC.

    I think it all started when I went form a MacBook with Snow Leopard on a MacBook Pro with Lion.

    Any help would be much appreciated.

    Thanks in advance!

    You use the mouse wheel to scroll?

    There are some prefs mousewheel, which control the behavior when you press the modifier keys.

    You can set the key to the action of each to 0 for normal scroll.

  • Support MacBook Pro OS 10.7.5 using Time Machine on hard drive external & Clean install on new SSD capital El

    I ordered a new SSD to upgrade my 2011 MacBook Pro that runs on OS 10.7.5. I would like to install own El Capitan on the new SSD. Can I save my current hard drive using Time Machine and an external hard drive and then re - download my old stuff in the new SSD? Is this possible at all?

    Basically, I want the new SSD to be as clean as possible. Obviously, I would only the files and applications on my computer current to be transferred. I would be grateful and recommendations on the best way to do this. Thank you.

  • iTunes (for laptop MacBook Pro) for iPhone

    Until now I was able to maintain a significant library of iTunes on my computer (laptop MacBook Pro) and transfer only the files currently, I wanted to play on my iPhone 5s, but now he has completely developed a mind of your own.  Even with 'Manage music manually' checked, he insists on the importation of (or at least the poster on the phone) ALL your iTunes library!  (But I would say it's actually being imported into the phone).  She adopted a very attitude "all or nothing".  When he downloaded everything on the iPhone, I was able to remove everything by going to settings > general > storage and use iCloud > storage to manage and simply remove all pieces of music.  Before when I did this, the icon of music seemed always with 'No Data'.  Now it has disappeared completely, perhaps because the phone is disconnected from the computer.  The songs seem to have disappeared, but it has developed two problems:

    1. it displays everything when connected to iTunes - I can't tell which are actually on the phone, unless they are all.

    2. some files iTunes, when I slip and fall, apparently correctly appear on the phone, the other files created identically, which did not play on the computer, and who were on the phone before, now does not transfer to the phone, and others sometimes and sometimes not.  Then when I stop to think or straighten, iTunes spilling everything on the phone and I need to remove again.  Summer in circles for hours and no end in sight.  Go to bed and in the hope of waking up with a usable answer.  Thanks for any help.

    < re-titled by host >

    Trying to import from iTunes to my iPhone, I checked "Manually manage music" and tried to check and uncheck "Sync only Checked songs."  At best, it is not good as all songs are checked for "Songs", while the single view where I can keep collections at halfway straight albums.  (Seems not a way to alphabetize or elsewhere to organize the albums - you just have to scroll through everything in a random order, select those you want, and then have iTunes maniacal laugh as it does not account of your choice or simply synchronizes everything.)  At worst, checking or unchecking "Sync only checked Songs" doesn't make any difference because there seems to be no way to check entire albums and ONLY the albums you want.  Whatever it is, with "Sync only checked Songs" checked or unchecked, iTunes will not a * thing until I started to drag an album on the phone and then it drags the WHOLE LIBRARY WITH HIM, AND IT SEEMS IMPOSSIBLE to GET JUST THE BIT I want AND NOTHING else!  She was torturing me for three days.  It is horrible and evil and is determined to make me drag my computer everywhere and never listen to more audio on the phone.  I hate it and they must be destroyed.
