Problem with Macbook Pro early 2011, webcam not working in any apps and windows 7 or 8 on bootcamp, keyboard backlight not working?

Hi Guys
I recently bought a second hand early 2011 Macbook Pro 15 inch and are having 2 problems. The first is that none of the apps detects my webcam at all, the second is, i have Windows 8 installed on bootcamp but are unable to get the keyboard backlight to work in 7 or 8. The backlight works perfect in os x 10.8.5 though. I need a little bit of help guys.....

Go to Apple Menu / About This Mac. Click on More Info ... next on System Report. In the left hand column, under Hardware, select USB. The right side will show the USB Device Tree. Look through that and check for "Built-in iSight". That is your camera. If it is not listed the camera is not working.
For backlighting, try this: go to System Preferences / Keyboard. Uncheck "Adjust keyboard lighting in low light".

    lost my application dvd that came with macbook pro, early 2011. any alternatives to get the applications in that??

    I'm not sure how this is an iTunes issue, but anyway, other than buying the apps from the Mac App Store (note that iDVD and iWeb are not available via the App Store), the only alternative is to call Apple support and give them the serial number of your Mac. They can usually sell you a new disk set for a reasonable fee.

  • Thunderbolt 2 external hard drive not working with Macbook Pro (early 2011)

    Hi,
    I'm new to this forum and I hope you guys can help me with this:
    I've recently bought an external hard drive that works on Thunderbolt 2 (LaCie d2 3TB). When I connect the new drive to my Macbook Pro through the thunderbolt port, the drive isn't recognized. However, the drive works fine through a USB connection.
    I thought that Thunderbolt and Thunderbolt 2 are compatible, however this doesn't seem to be the case. Maybe it's because the OS X / driver / firmware version that I'm working on that is not updated? I work on an early 2011 Macbook Pro: OS X Version 10.6.8 (Snow Leopard).
    Thank you very much for your help!
    Daniel

    Hi danielsh6,
    I recently bought the new Lacie Thunderbolt 2 D2 3TB and I had the same problem as you, i have a macbook pro early 2011, those support thunderbolt but many times there is a bug that doesn't let you connect any thunderbolt drives to your computer. The solution I found was installing this update:
    Thunderbolt Firmware Update v1.0
    Before doing this I would recommend you updating to mountain lion (not yosemite yet as there is still some glitches and more on preview's macbook pro's).
    Hope this helped!

  • Fan problems, running asymmetric with macbook pro early 2011

    With Yosemite I have found that the fans are running asymmetric. With a any program running, the control of the fans run without any sense. I´ve tried to reset SMC, reinstall OS X 10.10, use some fan control software, uninstall all fan control software (FanControl 1.2, smcFancontrol, Macs fan control, etc), and nothing is working. When I install a fan control software, I can control left fan but not right one.
    I own a macbook pro early 2011
    Thank you for the help.

    You might consider that it's a hardware problem and not necessarily the OS.
    Perhaps malfunction of the fan with installation of Yosemite is mere coincidence, perhaps it went wrong with the increased speed/runtime one sometimes sees on a laptop during a big install.
    Could be worthwhile to have it looked at by the folks at the Apple store.
    The laptop is 3 years old, after all, and sometimes fans go bad.
    Good Luck!

  • Graphic problems with Macbook Pro Late 2011 13"

    I'll try to explain it as clear as possible. This started to happen a couple weeks ago:
    My Macbook screen started to being white-blurred, and the image slows down while this happen. At first I thought that was happening randomly, but then -I guess- I realised that it was lid-related; when I open the lid more than 90 degrees the problem started to happen, sometimes it starts to happen even if the lid is in its 'working fine area' though , but after moving the lid up and down several times, it gets 'fixed'... until it happens again. There are times when it doesn't get fixed instantaneously, and it's really driving me crazy.
    My first thought was that it might be the flex (not sure if this is the right name of it tough), I mean the cable that goes from the screen to the logic board. If so, or even in another case scenario, I have an Early 2011 Macbook Pro 13" where I can use any part, except for the logic board, if needed.
    Thanks in advance.

    Well the Apple logo will always be visible through the screen when there is a fairly bright light behind the screen.
    That is totally normal.
    As for the freezing and since this is your first Mac computer I would like to make you aware of one thing.
    The way Mac OS X operating system works is slightly different then Windows. In Windows when you click the X in the upper right hand corner of the program you are using that program closes freeinig up the memory it was using. In the Apple OS, OS X, when you click the X in the upper left hand corner of the windows you are using all that does is close that active window. It dos not close the program. So if you have started up 2-3-4-5-6 programs to do something in them and then clicked the X all you have done is closed those windows for all those programs. The programs is still running. So you can end up with several programs using memory when they shouldn't be. You have to actually close those program by first using Command+Tab to see what programs are still open then go to the menu bar on the right side where the name of the program is displayed and click on that name and select Quit Program Name. Or once the name of the program is in the menu bar press Command+Q (Quit) to close that program.
    Get in the habbit of always using that keyboard shortcut when you are done using a program.
    Having multiple program open will cause the system to run slow.
    The hard drive Apple is putting the newer Macbook Pros are of the slower type. Running at 5400RPMs as opposed to the faster 7200RPM models. Why I don't know as the faster drives don't cost that much more. Because of this all program run slightly slower. To open, to save files to and when used as a swap disk to expand on the physical memory in the computer. Which in turn will make the system seem sluggish and can casue some freezes.
    So make sure you have closed all programs before opening another, and only have at the most 2-3 progams open at the same time.

  • How i can submit a complain about hardware problem in Macbook Pro early 2011?

    Hello every one,
    I bought my Macbook on September 2011, and it worked fine with me for about 1.5 years, but suddenly i got freezed screen when it was on the discrete graphic card, then the same problem happened with the integrated one. and now a gray screen come after the startup apple logo, and the computer is not working. When i searched about this problem on the internet i found that many people faced the same problem and the solution is changing the main board, which will cost a lot of money. And when i contacted the custmer service, they reject to agree that this is a manufacturing problem and they insist that i should pay to get the problem solved because the warranty is just one year. So i want to know how can i contact Apple to complain about this issue, because they should extend the warranty about this problem because it happened for many computers from this generation.
    thank you in advance.

    I went to Apple store and they confirmed the problem as a problem in the main board or the main board and the screen. and here are some links for similar problem with the same model:

  • Issue with Macbook Pro (early 2011) screen going black.

    I installed an SSD with Mt Lion.  Periodically the screen goes black like it's going to sleep.  It hasn't done this in the past just noticed it the last few weeks. 
    The SSD is a Crucial with 8GB of Crucial memory.  I've got all the software fixes up to date.  Has anyone else seen this.  I've read a few postings, one mentioned issues with Mt. Lion and another with a logic board in the laptop. 

    Well, seem like there's already ton of thread related to this issue ...

  • Macbook Pro early-2011 crashing/locking-up

    Hello,
    My MacBook Pro (early-2011 model 15") has been locking up and crashing lately. It was recently upgraded to Mavericks OSX.This has happened only a handful of randomn times over the past two months. I don't think it has to do with the OS version because it did this a couple months ago as stated when I had Lion, and also ML. However, in the past 24 hours i have locked up around 5 times and crashed at 3 times.  I've attached the crash report below from the latest crash this morning. I use one usb port to connect to a Dell monitor using DisplayLink adapter, and the other usb port goes to a 4-port usb hub that has my wired keyboard, mouse, and phones that I test with plugged into. The mini displayport goes to another Dell monitor. Can anyone help me determine the issue? Does it look to you like the RAM has been corrupted and needs replacing perhaps? Or maybe it is this usb hub causing memory crashes from having so much stuff plugged into it? Log below:

    Hi Will-H,
    Thanks for using Apple Support Communities.  It sounds like more isolation might be needed to rule some things out.  I would recommend this article:
    OS X Mavericks: If an app freezes or quits unexpectedly

  • Macbook pro (early 2011) won't boot after sleep. Black screen with chime

    I put my macbook pro early 2011 (Quad, 8 Gb RAM, 2 x SSD-disks, external 27" LED-screen) into sleep mode a couple of days ago. Everything was fine then.
    However, the morning after it wouldn't wake up - this is the bootup process:
    - Black screen
    - Chime
    - Still black screen, nothing happens.
    So I've tried resetting NVRAM, SMC etc - no luck. Even tried the "Powerbutton" + "S" + Enter but to no avail.So I immediately began dd:ing my SSD-disk before trying anything else, figured it might be some preboot-corruption of some sort since I'm running FileVault2 with full AES-encryption.
    Now, the problem (after some troubleshooting) doesn't seem to be disk-oriented. Remember the black screen? I've tried pulling the SATA-cables one by one on the motherboard of the Macbook pro and discovered that when I pulled the cable which reaches over the optical device (just above the SATA-cable for the optical device) then I get a white screen and I'm able to get as far as boot-option, or even disk repair (if I run my SSD-disk over USB and without any cables (three of them) attacked to the motherboard).
    So since nothing works when I have disks connected or that third cable (some kind of logic board bridge? Reaches through the screen over to the other side of the mother board).
    Also worth noting is that I was running out of free disk-space on my system disk. The disk is 250 Gb and free space was about 5-10 Gb (less than 5%). I also make the macbook pro dump contents of memory to disk (since my disk is encrypted it resides safely there).
    So, my fear is that Apple hasn't used A-grade controllers for the disk drives (I've had drive corruption before, a Crucial 6 GB/s drive trashed less than a week before a presentation) and doesn't handle "unexpected events" nor signal/noise ratio very well. Maybe free space on disk was less than the 8 Gb needed to dump RAM (shouldn't have needed the full 8 Gb though) and this caused some kind of panic overwrite which trashed the controller?
    Anyways, I've attached an image of the motherboard and I am wondering - what does the top cable which reaches over the optical drive do? Is it connected to the logic-board?

    Looks to me like a fatal error on the hard disk. IMHO, the only solution is to boot from an external device, reformat the hard drive, and restore from backup. If you don't have a backup, you're in trouble. Boot from the external device, try to mount the int'l drive, and, if successful, back up as much as possible. Also, try running Disk Utility—it may be possible to fix it while booted from a different device, thought I wouldn't bank on it. At any rate, make sure to run an AHT afterwards, to check for possible hardware issues with the drive.
    If the machine is still covered by AppleCare, take it to the store by all means. But they won't try to recover anything from the int'l drive, just check it, erase it if they don't find hardware issues, and re-install a fresh copy of the OS.
    That's why you should always have at least 1 up-to-date backup (2, with one kept off-site, is better).

  • My MacBook Pro (early 2011) will not go to sleep

    Very recently my MacBook Pro (early 2011) suddenly stopped going to sleep whenever I shut it or even when I manually put it to sleep. I went to my schools help desk and they suggested restoring the computer to factory settings. I did this, reinstalled Mountain Lion and the problem seemed fixed. Then I backed up my files and again the computer would not sleep. I put the computer in safe mode and the computer would fall asleep. Any ideas what this might be?

    There is no output from that command line?   Maybe the pid changed.
    I'll repeat what I am trying to find out...
    1. You do a pmset -g on the terminal.
    2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
    3. The ps ax | grep n is supposed to display what the process associated with n is.
    It's the output from step 3 that should indicate what is causing you not to sleep.
    But speaking of sleep, that's where I am going.

  • EXACTLY what cable(s) do I need to connect my MacBook Pro (early 2011) to an external display with a 2560x1440 resolution?

    I am trying to connect my MacBook Pro (early 2011 w/ Intel HD 3000/ 384Mb) to an external display with a 2560x1440 resolution. Specifically, what cable/connections do I need to display at this resolution? I cannot get the display to work using a "Thunderbolt to HDMI" or a "Thunderbolt to DVI" connector.  Note:  I used both older and newer (uni-directional) HDMI cables on the first config, and a Dual-link DVI cable on the second config.   Apple specs state this is possible ( support.apple.com/kb/SP619 ), but I am at a loss as to how this can be done.  Thanks in advance for the help!

    You use a Mini DisplayPort to either HDMI or dual-link DVI adapter. If that component doesn't work, something's wrong with either the cable or something else in the connection.

  • Instant Hotspot not working on MacBook Pro Early 2011?

    Hi and tnxs for reading.
    I have a MacBook Pro Early 2011, and I cannot figure out how to use Instant Hotspot.
    It is regularly working as standard hotspot by activating it on my iPhone and checking the iPhone WiFi Hotspot from WiFi menu, but otherwise is not available after the iPhone goes on stby...exactly as before.
    Is this a limitation like the major part of Continuity?
