Macbook Pro left CTRL key not working

I woke my Macbook pro from sleep this morning and now the left ctl and shift keys aren't working. They were working fine last night, I was using both keys for photoshop, but now nothing. I've tried remapping the CTRL key to fn using KeyRemap4Macbook, but it doesn't work, even a restart. System Preferences doesn't show any change in keyboard layout or mapping. Has anyone else had this problem? The Macbook wasn't moved last night, nothing new was plugged in, and no liquids were anywhere near it. It's an i7 2.3 with 8gb ram, running Mountain Lion 10.8.2, thanks

Thanks for your reply Peter. I restored defaults, and restarted twice, but still nothing. Both keys work on an external keyboard, so I think that it's a mechanical fault. I'll send it back next week when this job has finished- let's hope that it's not part fo a faulty batch.

My laptop touchpad left mouse key not working

I have a Elitebook 8440p with windows 7 professional.The touchpad left mouse key not working ,but right mouse key works well.my driver is synaptics 14.0.10 090ct09 and the touchpad name is synapticsTouchPadV7.2.
thanks in advance.

i had the same problem. what solved this for me was to simply go to device manager and under mice and other pointing devices uninstall the touchpad, i had a usb mouse handy just in case i needed it, but then i restarted the laptop and it auto reinstalled touchpad for me and then all options worked on startup.

My MacBook Pro internal speakers are not working, what happened?

My MacBook Pro internal speakers are not working, what happened? If I plug in earbuds or external speakers, there is sound. In sound preferences, internal speakers are not a choice. Why doesn't my internal speakers work?

Hopefully one of these steps should solve the problem.
1. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
2. Reset PRAM. http://support.apple.com/kb/PH4405
3. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
Best.

Macbook pro (early 2008): Trackpad not working under Windows XP

My Trackpad worked regularly under Windows (Bootcamp) and Mac OSx until some months ago my Motherboard had to be exchanged because of a fault function of the graphics card. When I started Macintosh after the Macbook pro was repaired the Trackpad worked regularly, but under windows the mouse didn't react to moving the finger or clicking. I reinstalled the drivers, but this didn't fix the problem.
What shall i do now? Thank you for any advices.

since my mac is year and two months old (funny, two months and you are screwed).
Not if you had of purchased Apple Care. You would have been covered for 3 years.
What I would like to say to the Apple:
This is not the place as Apple does not come to these forums.
These are user-to-user forums where everyday folk post "technical" questions and offer answers to each other voluntarily. No one here works for Apple nor does Apple get involved in responding. Not even sure if they "lurk."

Help! Left shift key not working!

all of a sudden today my left shift key has ceased to work. the right key works fine, increasing the chance that it's hardware. I'd like to remove the key cap and see if re-seating it might fix it. I've looked in many places on how to remove it, but no luck. Is there a web site that shows how it's done for a G4 Aluminum? Thanks in advance.

Marco,
I've been having intermittent left shift key problems for several months. My laptop is now 3 days out of Warranty, Apple web site says so. Anyway, the only reliable fix I've found is to do a re-boot. I can also (sometimes) get reliable shifting if I slide my finger closer to the outer edge - meaning, no shift if pressed on one side of the key, sometimes shift on the other side.
I've also had success shifting in one application which seemed to "clear" the problem in the original application. Example: typing in Mail when left shift key stops working. Switch to MS Word, shift works fine. Switch back to Mail, shift works fine.
I have a feeling it's a combination of software and slowly failing hardware. I feel bad to have waited until after the warranty period, and now the problem is getting worse. My wife was just in for brain surgery, so you can't really blame me! She's doing fine.
So, my suggestion is to try rebooting to see if that clears a memory buffer problem. Kinda annoying, maybe a future software update will fix the software problem?

2007 MacBook Pro ctrl key not working

Hi all,
I have used various iterations of bootcamp with my 2007 macbook pro without problem. I have also sucessfully installed Windows 7 64-bit using bootcamp and got it working almost perfectly (sound, video, magic mouse) despite it not officially being supported by the version of bootcamp that came with Snow Leopard.
My only problem now is that the control lkey isn't working. I've tried various keymappers to map it to another key (generally the Apple key) to no avail. And when I say it isn't working, I mean it's not working at all. Key mappers don't recognise when I tap it, I can't Ctrl-C to copy or Ctrl-anything to anything.
I have installed the Apple keyboard driver and everything else works perfectly, including the F-keys, Fn, alt and the Apple key (which opens the start menu). Any suggestions for how I could fix this would be greatfully received.
Thanks,
Alexis

Sadly it turns out that it's not working in OS X either. I had convinced myself it was a software issue but it is apparently hardware. Shows how seldom the control key's used in OS X doesn't it.
If anyone has any suggestions as to how I might have a bash at fixing it, please let me know.
Thanks,
Alexis

Ctrl key not working on Macbook Pro running Windows 7

Hi
Recently I took my Macbook to the Apple store to have the top case replaced because there was a problem with the trackpad. Since getting it back, the ctrl key doesn't work when I boot into Windows 7. Anybody got any solutions? I have tried fn + ctrl as well.
Graham

Try install the newest Intel® HD Graphics Driver.
http://downloadcenter.intel.com/Detail_Desc.aspx?lang=eng&changeLang=true&Dw nldId=22376
It includes the Intel displayaudio driver and some people solve the audio problem on Windows 8 after install this driver.
Rember backup first before test the driver.

Macbook Pro Keyboard and Trackpad Not Working

few days ago, my Macbook Pro keyboard and trackpad started to act very oddly.
Basically, the keyboard doesn't work at all. I press down the keys, and all I get is that error message sound. The volume and display brightness keys seem to work, but almost all of the others just won't type anything. it-s like any key command or alt would stay pressed so when i click any key its trying to perform other function instead of just typing the letter. that-s probably the reason why the trackpad is also being very odd. When I first turn on the laptop, it seems to work as normal. I can click on an application, and it opens. But about one minute after the laptop first starts, it's like anywhere I click on the trackpad is a right-click. To open an application, I click like I normally would but instead of opening, a menu pops up as if I right-clicked. This happens in Finder and everywhere else that I've tested (for instance, I can't drag any Finder windows to different positions on the screen, because it acts as if I right-clicked instead of left-clicked), no matter whether I tap or click the trackpad.
I have reset my permissions, but that didn't fix anything. I verified the hard drive and it said there were no problems. A big issue is that I can't do anything that requires me to type in my password, since I can't type anything. I tried to reset the PRAM, but I don't think that it even registered me pressing the Command-Option-P-R keys when I booted up, so i just removed the battery for a while, i am not sure that did anything at all.
i tried to reinstall the os, i had mavericks and i installed a fresh mountain lion but the problem persists. i recently installed virtualbox and the keyboard seems to work right as long as i do not press any of the following keys command, alt, shift, etc.. if i press any of them same thing happens. i found that if i connect a usb keyboard everything works, but when i use the inbuilt keyboard the problem is back and a i have to connect disconnect the usb keyboard to be able to type or use the trackpad normally.
any help would be appreciated.
Thank you.

No one cared enough to answer.

Mac pro left shift button not working...

Hello my mac pro left shift button is not working what would be the problem, is it the major or minor problem plz help me...

Mac Pros are desktop, MacBook Pros are notebooks. There are usually two shift keys. Have you tried both?
Have you made sure the Caps Lock key is not enabled? Have you made sure the Num Lock key is not enabled (clicking either will disable them if they are enabled). Speech recognition can make a key give an alternative command if you set that up, try disabling speech recognition to see if that's the problem, or one of the Universal Access settings can do the same. Go to Apple menu -> System Preferences to manage those.

Keyboard Doesn’t Work
Keyboard Keys Do Not Respond

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".

MacBook Pro update at startup not working properly rendering MacBook unusable.

My MacBook Pro loads an update at the grey screen then shuts off. When it turns back on it attempts to finish loading the update again. Is there a way to stop this update from happening at the startup screen at this time?

tye91,
you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it reach the login screen now?
