It shouldn't. Take it in for service as there is definitely something amiss.

  • Why does my Macbook Pro battery not even last me 2 hours even just browsing the internet or typing a document?

    So my Macbook Pro 2011 that isn't even a year and a half old only lasts me about 2 hours of battery.  My brightness is set to only 4 notches most of the time and I mostly have google chrome and itunes or spotify open when I am using it.  I have to charge it about 2 times a day.  My old original unibody macbook lasted a longer time than this.  Today, my fans were running faster than normal and my battery drained 20 percent in less than a half hour. 
    Here is all of my battery/power info:

    I would greatly apprecieate any feedback or help that anyone could give me.  I don't even do processor intensive tasks so I don't know why my battery isn't lasting me more than 2 hours.
    Thank you.

    it was using 53.5% of you CPU. Which if used over a long period of time, a lot of battery will be used and it will drain quickly, try figuring out what this is and use it less often, or try deleting it if it is not important.

  • Why does my MacBook Pro battery discharge even when the charger is plugged in?

    I've been having a myriad of problems with my MacBook Pro's battery. The main problem is that when in use, the battery steadily discharges often at a very quick rate even when I have the charger plugged in, the only way I can get it to recharge is to close the lid or turn the computer off, however, it has recently started to take a very long time to recharge (I left it for 12 hours and it charged from 0% to 60%). I also noticed that while off, the charger light occassionaly goes green and then back to orange every few minutes. When I manage to get the battery up to 100% charge, it usually stays at 'Charged' for around 5 or 10 minutes and then it just comes up with 'Calculating...' as it slowly discharges, it also occassionaly claims that it is recharging and that it will take around 6 to 8 hours but it only charges about 1% of the battery and switches to 'Not charging'. Also, sometimes the charger light wont come on when it is plugged in and the Mac refuses to acknowledge it is plugged in for some time.
    I took it to the Apple Store a few months ago and one of the Geniuses reset the System Management controller and did a quick hardware test which seemed to fix it but the problems returned soon after, I cannot enter the hardware test screen and subsequent attempts to reset the SMC have done nothing, he also tested the charger and tried it with another charger but it did not help.  Hope you guys can help me as I am completely stumped by this and its beginning to annoy me as my Mac is becoming almost unusable.

    MacBook Pro (13inch, Mid-2010)

    May be better off with a new battery.
    Hope everything turns out right.

  • Why does the MacBook Retina 15" do software scaling to the native resolution of 2880x1800?

    OS X does not allow changing the viewport resolution to the native 2880x1800, and it suggests 1440x900 as a retina optimized one. This means that software scaling is done on the fly. My question is, why?
    I have two suspicions:
    1. Running everything at the native resolution puts a bigger strain on the GPU, hence slowing down the OS, putting down battery time.
    2. The number of apps using retina-ready sprites is miniscule, hence Apple does not want to mess with the user experience. Although I doubt it, as software post-processing is done even now, and apps with non-retina sprites look slightly blurred. If the native resolution would have been used, they would just look a bit more blurry.
    Just some comments:
    1. Switching to the native resolution will make everything smaller, up to the point of not being usable. But this is a non-argument, as the OS could be smart enough to use bigger versions of the sprites/icons/text. Apple already demands that developers use hi-res sprites (OS X Human Interface Guidelines), hence everything could be scaled x2 and it would be the same size at 2880x1800, as it is at 1440x900 in the current version of the OS.
    2. Technically it is possible, as outlined here: Running the Retina MacBook Pro at Full 2880x1800 Resolution. Have a look at the comments too, there are some interesting observations in line with this question, but no definite answers.
    3. I am aware that the OS X Cocoa server is running at native resolution at all times. This question is concerned with the viewport resolution, which requires hacks to be set to the native one.
    Can answer on Quora if preferred (http://www.quora.com/OS-X/Why-does-the-MacBook-Retina-15-do-software-scaling-to- the-native-resolution-of-2880x1800)

    This is a common problem with new Mac notebooks. There arre many threads on this and other forums about it.
    Tae your Mac to an Apple store to be fixed or replaced.

  • Why does my macbook pro retina display shutdown while entering the administer account

    why does my macbook pro retina display shutdown while entering the administer account

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and  Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Why does my MacBook Pro and Mac Pro keep freezing?

    Why does my MacBook Pro freeze?
    MacBook Pro
    2.4 GHz intel Core2 Duo
    4BB 1067 MHz DDR3
    OSX 10.6.8 Snow Leopard
    I turned it on and I went to safari to look things up. Safari froze and then the whole thing became unresponsive - the mouse could move the cursor but it couldn't open any programmes.
    Tried safe boot several times. No help.
    Tried to repair disc permissions. The first time it got a little way then said 'user stopped repair' or something  - though I didn't touch it. Tried again it got all the way through and said 'repairs complete'. But no help.
    Couldn't clear cache etc as couldn't get to the relevant part to do it.
    Opened in single user mode. Ran the fsck -fy thing twice. First time it said both “The volume appears to be OK” AND “FILE SYSTEM WAS MODIFIED.” In 2nd run it just said  “The volume appears to be OK”. No help.
    Booted it up from the Superduper bootable backup version on a USB external drive. It seemed to boot up ok but then tried to click on something and the same thing happened - spinning beach ball and it just hung.
    Erased hard drive and reinstalled snow leopard but it just does the same thing. Suggesting a hardware issue not software but...the Eerie thing is, we tried backup version on boyfriends Mac Pro and it worked fine on there but 24hrs later his Mac Pro has got exactly the same screen freezing, unresponsive issue. Could this suggest there's something evil lurking on my back up? Can't get an appointment at Genius Bar until next week and need to get some work done, so hoping someone might have some ideas?
    Cheers

    ... does Apple products work much better with using Apple routers?
    While a genuine Apple router is likely to result in success, the reason for having one instead of another product is that it eliminates a lot of uncertainty. For example, we do not know the model D-Link product you have so no one is in position to speculate what the problem might be. Also, it makes support on this forum easier since there are only three AirPort models to choose from and they all work more or less the same.
    Generally speaking your iPods, iPads, MacBooks, and AppleTV ought to work with any router though, provided it is fairly recent and meets accepted industry standards. If in doubt you can purchase an AirPort Base Station, which comes with 90 days of free telephone support. If it does not result in any improvement for you, you can always return it for a complete refund. The return period is 14 days and be sure to keep all material - receipt, box, manuals, etc...
    If you elect this option be sure to follow its installation instructions, the most important of which is to power down your modem prior to connecting the AirPort Extreme, Express, or Time Capsule. All your other equipment will need their network settings adjusted to "forget" the D-Link network and connect to the new one.

  • Why does my MacBook Pro make background music and video quieter when I am on FaceTime?

    Why does my MacBook Pro make background music and video quieter when I am on FaceTime? When my girlfriend and I are trying to watch a movie on Netflix together while on FaceTime my MacBook Pro always decreases the volume of any background sound on my computer so I can barely hear it. Is there a way to fix this? Thank you!

    Have the same issue too. Apple can you please change this annoying feature. You are making long distance relationships more difficult.
    I like how Facetime was with the old iOS, where nothing was dimmed. OR at least maybe if you could give users the option to turn on or off dimming of facetime.

  • Why does my macbook pro "goes to sleep" when charging?

    Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
    I read from threads that it is a logic board problem....How do I solve this problem?

    Try an SMC reset. Follow the method for "a battery you should not remove yourself."

  • Why does my Macbook Air make a single buzz/beep?

    Why does my Macbook Air make a single buzz/beep every time I open it or turn it on? It doesn't happen after again after the initial buzz. If I open it after it has been sleeping, it starts up and then there is a buzz. This has only happened since I downloaded iOS Maverick.

    Beeps on startup:
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images.
    5 beeps = processor is not usable

  • Why does my macbook pro get hot

    Why does my Macbook pro get hot while I am only on my email account?  This is a recent change.  It gets too hot too put in my lap.  Is it a battery issue.

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.

    Why does my library show no content even though ATV2 can see my library?

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

  • Why does my macbook show  emails as being sent twice

    why does my MacBook Pro  show  emails as being sent twice

    You don't need to delete them form iTunes on your computer. Notice the dotted circles next to the songs. That indicates that the songs are essentially in limbo. They may not be on your iPad or they might appear in the Music app but will not play.
    Sometimes unsyncing those songs will totally remove those ghost traces of the music nd sometimes, you have to restore the iPad to get rid of those traces of the songs.
    If you Google "grey dotted circles next to songs in iTunes" you will find a plethora of articles that talk about this.
