Microphone and Line In Suddenly Not Working Macbook Pro 15" Early 2011

Yesterday without warning, my internal mic stopped working on my Macbook Pro 15" Early 2011. I discovered this when the recipient of a Skype call couldn't hear me, and verified that the mic was not getting any level in the Sound system preferences pane. There is also no microphone input happening when I plug in my iPhone headset to the headphones jack. The audio out seems to be fine. I had to use a USB microphone to get any sound into the computer. I used the microphone just a few days ago without any issue.
I've already tried:
Rebooting
Resetting PRAM
Creating second account to test audio
And none of the above had any affect. Other note: I recently had the GPU of this computer replaced under Apple's special replacement plan. Anything else I should try before making an appointment to have the hardware looked at?

pushyourmind,
If you’re up-to-date with Software Update, then you have the correct firmware installed. If you’re running 32-bit Windows 7, then Boot Camp Support Software 4.0.4033 contains the correct drivers; if you’re running 64-bit Windows 7, then Boot Camp Support Software 5.1.5621 contains the correct drivers. Which ever support software corresponds to your version of Windows 7, try downloading the corresponding .zip archive and following the installation instructions on the corresponding link above when booted in Windows.
Boot Camp 5.1 supports Windows 8.1 on your model MacBook Pro if you’re running OS X 10.8.3 or newer. Earlier versions of Boot Camp and older versions of OS X don’t support Windows 8.1 in Boot Camp on your model MacBook Pro.

I have a MacBookPro8,2 1.0 - 15" - I purchased in March 2011. I have been using bootcamp 5.0 (upgrading now to 5.1) and running Windows 7.
Two questions:
1. what is the best way to know if I have the correct firmware and drivers for this computer?
2. and does bootcamp support windows 8.1? thunderbolt display... others

I got my Macbook Pro 17inch (early 2011) back from Apple (they had to replace the logic board) and now my microphone is not working

I got my Macbook Pro 17inch (early 2011) back from Apple (they had to replace the logic board) 3 days ago, I had a terrible experience as the genious who gave me my solid state disk for safekeeping lost my disk's brackets thus I had to wait 2 more hours until they find one after 10 days of waiting for the repair. I noticed some weird sounds, like somehting is moving with the mac 1-2 times, even if I have no mechanical parts other than the fans, but my real issue at the moment is that my microphone is not working. I can see the mic in the System Info however and in Audio Midi Setup. In the Audio Midi Setup I see that the master chanel is turned off and I can't turn in on. Ch 1 and 2 are on full. I also noticed the first seconds after the comp. boots the blue bar goes to the middle in the System Preferences -> Sound -> Input. Any ideas what to do or try? I do not want to go back to the apple store as it is 50 minutes away from here and I need my laptop as a computer science student. Everything else is working perfectly.

You need to call both the store that did the repair and Apple directly, warranty service or Apple care, and report this problem with both of them and get a ticket number of some kind (some kind of verification number) that the unit just came back from major service with this problem and that you want it fixed when you can lose the use of it, which is not right now.
Without doing something like that they could easily say it is damage not covered under the normal warranty.
God knows what the repair center did and did not do to it while it was there.
And depending on when you actually bought it the warranty could run out in the mean time.

I have a macbook pro 13" early 2011 version and what to install windows 7 on it via bootcamp but not sure that whether to install x64 or x86 version? which one will work better

There is no need for anyone to use 32-bit version anymore.
Retail comes with both. Or you can save on just buying 64-bit System Builder disc.
Better support for today's hardware with larger video graphic memory and systems.
Better memory management.

Right, MacBook Pro 17" early 2011(Built March) and my new OCZ sata III 6G not working, when is Apple going to admit there is a problem with the Intel's 6 Series Chipset. In System Information it says "Link Speed: 6 Gigabit" which is sata III.

My MacBook Pro 17" early 2011(built March) and my new OCZ sata III 6G are not working together, when is Apple going to admit there is a problem with the Intel's 6 Series Chipset. In System Information it says "Link Speed: 6 Gigabit" which is sata III and in my MacBook Pro it does not work.
Now MacBook Pro 17" early 2011 built May onward do not have this problem it was fixed in the Intel's 6 Series Chipset. (So there is a problem). Cam I have my MacBook Pro fixed please.

After biting the bullet and ordering more RAM, my computer now is working a ton better. So that must have been the main issue. With 8 GB RAM, I can now even run Parallels fluidly (better than my work PC!) where before simple things like logging in to my MBP after reboot could take forever.
The place I went to had several other people getting RAM upgrades at the same time as me, so between this and other comments I've seen in discussions here and elsewhere on the Internets, I take it to mean that either Apple should bump up the base RAM on its new machines, and/or stop charging so much for additional RAM.
I refused to believe a Pro machine bought with Lion installed would come with too little RAM for light to medium usage, but it was apparently the case. I'll mark this as a correct answer and hope some other poor soul will come across this thread and be helped by it.

MacBook Pro 13" Early 2011 Backlight Keyboard Not Working?! Software Problem...

So my "MacBook Pro 13" Early 2011" backlight keyboard hasn't been working. I have tried LabTick today, doesn't fix anything. Even in high or low lighting situations (dispite the Adjust keyboard brightness in low light being off) doesn't like to go on. It doesn't give me a circle with a cross like it does with that box checked in day light. It shows on the screen the
16 dots fully light after hitting F6 fully, just it doesn't light up. I one time had to reset my Mac OS at the Apple Store, it fixed the problem, but when I restored with a time machine backup, it went back to this software problem. How can I fix this?! What is wrong with my OS? Mountain Lion? How can I fix this?!

If it does not detect the display automatically, try going to system preferences>displays, click detect displays.

15" i7 Macbook Pro from early 2011.takes the mac laptop two or three tries to boot successfully. It would turn on, show gray screen, shut down, turn on again, show gray screen, shutdown, and then turn on, show gray screen, before it can finally get

Hello All,
I have a 15" i7 Macbook Pro from early 2011. The past few weeks, it has been getting increasingly difficult to get on my computer. It takes the mac laptop two or three tries to boot successfully. It would turn on, show gray screen, shut down, turn on again, show gray screen, shutdown, and then turn on, show gray screen, before it can finally get to the dark gray log-in screen. Even when I finally get logged in to start working, thinking it would be okay now, it shuts down randomly.
I've ruled out the possibility of a software problem because I've just done a clean re-install of Mac OS X Mavericks on my computer just yesterday.
I did upgrade the RAM recently, about a month and a half ago, from 4GB to 16GB, I went to the apple store four days after that upgrade to have them do a hardware test, and clean the inside of my laptop, which helped with previous heat issues. When they did the hardware test, the hardware was all registered as fine from their system.
I've tried resetting the SMC, PRAM, and doing the internet recovery hardware test, but to no avail. I thought I could at least find out what parts needed to be replaced from the hardware test but it seems that when the hardware test is almost finished, the computer just shuts down, So I am unable to see the results.
My computer is also having battery issues, under battery condition, it says "replace now," parts have been ordered, waiting for arrival. But if the battery health is low, it should still boot up fine, it would just hold a significantly less charge.
Could this be a hard drive issue?
Has anyone had similar symptoms and how was it resolved?
Does anyone know what I can do to alleviate this issue?
I haven't had time to take it to Apple because I'm currently taking a 21 credit semester academically. I'm an art and design student so my computer is basically the bane of my existence. Help! Any constructive advice is welcomed!
Thank you so much for your input!
-Christina C.

I am having the exact same problem with my 13" early 2011 Macbook Pro. I have 10.6.8. I used the disk that came with the laptop to restore the OS to 10.6.7 but the problem existed there too. I have now updated it back to 10.6.8. The problem still exists. This doesn't seem to be limited to an OS version and seems like an issue with device driver or with hardware. I will try to take it to the Apple store and see if this gets resolved.
You too have a black screen in Windows 7. ?

My MacBook Pro 13'' Early 2011 is not booting.

Hello,
I have a Macbook Pro 13'' Early 2011. Last week I tried to replace the thermal paste on the processor and on the graphics chip. I followed a video tutorial and an iFixit tutorial step by step during the entire process. Once I was finished I decided to turn on my Macbook and give it a spin. Unfortunately it didn't work, although I haven't touched or damaged anything on the logic board, as far as I'm concerned.
The scenario goes as follows:
I press the start button..
The fan spins once, the hard drive reads for a second and the sleep button flashes for a moment. I am not hearing any chime, neither does my screen go on.
The Macbook Pro turns off again automatically.
I am going to open it once more before it give it to the authorized Apple service. Do you have any idea where the issue might come from?
Thanks for your replies!

If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the startup drive, or some other hardware component, is failing. Back up all data immediately, then make a "Genius" appointment at an Apple Store to have the machine tested.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

About AirPlay and Airplay Mirroring
AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.

Thanks to the $15 Beamer, AirPlay streaming is still possible on Macs that do not support Airplay and mirroring.
Another solution is the Air Parrot.

SD card reader is not working in my MBP early 2011. Is there any solution?

SD card reader is not working in my MBP early 2011. Is there any solution?

on my macbook iphoto didn't recognise my camera or card reader after upgrading to iphoto '11,
Evenutally I went to an application called Image Capture which I seem to have already. This read the camera contents. I selected the images I wanted and then imported them into iphoto which was one of the options given. It worked. God knows why one has to go through two steps. But I'm feeling pretty triumphant. This may help you if you haven't already sorted it.

When i connect my philips 170c monitor to my macbook pro 13" early 2011, it does not detect the second monitor?

help! i've googled around, but none seems to solve my problem
my macbook pro is early 2011, 13", running lion.
the philips monitor is vga only, so i have a mini display port to vga adaptor and connecting it to the vga.
the screen on my mbp does turn blue, but no input is detected on the external monitor.
any advice?

If it does not detect the display automatically, try going to system preferences>displays, click detect displays.

Yosemite on Macbook Pro 13'' early 2011: crashes and loss of functionality

After the OSX update my Macbook pro 13'' early 2011 has developed lots of problems: apps crash, battery doesn't last like before (5 hours in standby instead 10), Safari opens pages in 2 minutes and when I try to turn off the mac, it keep on working. I will try with a clean installation, but do you think this is normal? Thank u for the support.

The battery is non-removable, so if you want Apple you have to go to the Genius Bar.
As far as genuine Apple memory, I think it's the same thing. You may get it in the store, I don't think they sell it online. You can try calling the 800 number. You seem to want the Apple RAM only, but I have to tell you that most of us here recommend Other World Computing or Crucial.

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

you can upgrade to 16GB if you wish to do so...
average price for 8GB 1333MHz DDR3 is around $50 - $75 depending on the brand.
why not spend $100 and go with 16GB 1333MHz from Crucial or Corsair.
you can get them from Amazon.com or newegg.com
see image below with 16GB Patriot Mac Series 1333MHz for $100.
