Unibody macbook caps lock stuck on sound not working got wet.

My Macbook got wet due to a flower vase tipping over (cats)  I have replaced the keyboard and the backlight, im thinking it needs a logic board.  The sound dose not work and the computer comes on when its closed, caps lock stuck on. External keyboard works ok.  thanks for your time

I've also installed Onyx and performed maintenance and cleaning tasks. No difference...

  • Apple Keyboard: Tab, Caps Lock, Tilde and Esc not working.

    Yesterday I turned on my mac and was filling out some form and discovered whilst trying to go the next field that my tab button wasn't working. My tilde, esc and caps lock buttons won't work either (light comes on when I start up and pull out and plug keyboard back into USB port). It's strange that they're all tucked up in that left hand corner.
    Has anyone else come across the problem or have any thoughts about curing the problem?
    Cheers,

  • MacBook Pro 13" late 2011 sound not working.

    There is no red light in the headphones input, nor anything I can do with sound and MIDI. It says that I use my internal speakers. Despite this, the startup sound does still function.
    Any help I could get would be very appreciated!

    Go step by step and test.
    1. System Preference > Sound > Output > Internal Speakers
        Highlight  Internal Speakers.
        Make sure that Mute is not enabled.
    2.Plug in and  remove the headphone.
    3. Reset PRAM.  http://support.apple.com/kb/PH4405
    4. 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".
    Best.

  • ESC Caps Lock and Tab keys not working

    I have keys that are not responding on the key board while others are working just fine.

    Please reset the SMC, this may take up to 3 attempts to "take." If you still have trouble then try a USB keyboard and see if that works, if it does that points the finger at the keyboard which will need to be replaced.
    To do a SMC reset, simply power off the computer, remove the power cord from both the wall and computer, wait 15-20 seconds and reboot.

  • Message tone, music, lock/keyboard sounds not working...tried everything =[

    Hey all, iPhone 4s has gone mental!
    I have read through many posts on sound not working and i have tried everything, previous back ups, complete restore, clean out the headphone port, hard restore, also the volume buttons on the side when pressed will show ringer but no volume adjustment bar pops up =/ and the change volume with buttons is 'on'
    unless my headphones are plugged in nothing works, except my ringtone.
    any other suggestions to fix this would be massively appreciated =]
    Cheers all

  • AUDIODG.EXE hogging 80-100% of CPU and sound not working in Vista . . .

    I posted this on a Microsoft Answers Forum but none of the techs or people reading have been able to help so far.  I'm dying to get to the bottom of this:
    Here is my computer:
    MSI K8N Neo4 Platinum
    AMD Athlon 64 3000+
    2GB RAM
    XFX GEFORCE 6600 GT 128MB DDR3 DUAL DVI & TV OUT (PCI-E)
    200GB WD SATA HDD
    500GB WD HDD in external enclosure via USB2
    NEC ND-3520A 16X DVD±RW Dual Layer DVD Burner
    LG CD Burner
    I've been using Vista Home Premium successfully for some time.  Recently, not too long after I did a clean wipe of my OS, my audio would stop working.  The way it would happen is that everything would work fine until I started iTunes or another audio application and when I would hit play, things would lock up.
    Upon inspection of my system resources, I'm noticing that the audio platform for Vista, via the audiodg.exe, is using close to 100% of my CPU resources, even when the computer is making no sound at all.
    I've had a Sound Blaster Live! card in my computer for some time but I was not using it; I use the Realtek AC'97 audio drivers that are on my motherboard instead.  I thought that the conflict may be the computer wanting to recognize my Sound Blaster, so I took it out of my computer but the problem seems to be worse.
    Are there any BIOS setting that need to be adjusted for my sound to start working again?
    I'm very reliant on the audio processing power of my computer (I'm in the radio industry, part-time) and this is a huge drag on my productivity.
    Any tips would be much appreciated.
    REPLY #1:
    Thank you for using Microsoft Answers forum.  I suggest going to the manufacture of your sound card and download the latest drivers and install them.
    MY RESPONSE:
    Good suggestion.  The problem is this:
    I am running on-board audio.  I have an MSI K8N Neo4 Platinum motherboard which runs "Realtek ALC Series AC97 Audio Driver" and there is no version for Vista. They have a version for Windows 2K/XP and one for Windows XP 64bit.
    Should I use on of those and if not, then what?
    UPDATE (from me):
    I took a chance and found a Realtek AC'97 driver for Vista.
    http://drivers.softpedia.com/progDownload/Realtek-AC-97-Audio-Codec-Driver-Vista-6183-Beta-Download-18114.html
    I went to install it and the install hung.  So, I closed one of the install windows and then the InstallShield app continued like it was working.  So, I hit "Restart my computer".  Well, the reboot hung too.  So, I reset the PC manually.
    When the computer came back up, the sound worked.  Hard to tell if this will fix it for good but it's promising.  Chaotic.  Unpredictable.  Annoying.
    REPLY #2:
    Before you tried updating drivers, did you try rebooting 1st?
    I'm just trying to determine if rebooting your system is what resolved the issue - thank you
    UPDATE II (from me):
    My computer is behaving the same way it was before.  AUDIODG.EXE taking up 80-100% of my CPU and the sound not working.
    Any other ideas?

    Small update: Despite my intelligence, good looks and vast experience I use Google sometimes. To my surprise this file turns out to be a Windows one. Here is someone who is much happier, and since it is some way in my line of thinking I'll quote it, but you might take my previous advice as well:

    "- Open up msconfig.exe > Manage startup programs.
    - Disable ALL Realtek entries
    - Close msconfig.exe
    - Right-click on the speaker icon > Audio devices > Speakers (properties)
    - Go to the enhancements tab
    - Check the box to disable all audio enhancements
    - Close the menu
    - Right-click on the speaker icon > Recording devices
    - Disable all your microphones (yeah..., the actual problem seems to come
    from voice inputs rendering..)
    - Close the menu
    - Restart your computer"

  • Sound not working for text alert just vibrate

    Sound not working for text alert just vibrate and no sound on keyboard

    I'm having the same problem, it just started today (11/13/2012). 
    Settings > Sounds> Text Tone = Tri-tone
    Lock Sounds = On
    Keyboard Clicks = Off
    The mute button is also in the correct place (ring, not mute).

  • IPad sound not working

    iPad sound not working. Need help

    Is it working on any apps e.g. Music and Videos apps but not third-party apps or notification sounds ? If you do get sound in Music and Videos then have you got notifications muted ? Only notifications (including games) get muted, so the Music and Videos apps, and headphones, still get sound.
    Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

  • When I unplug Apple headphones from my MacBook Pro sond from internal speakers not work, and system soud preferences displayed: Output: optical digital out port only

    When I unplug Apple headphones from my MacBook Pro sond from internal speakers not work, and system soud preferences displayed: Output: optical digital out port only

    If you see a red light in the audio output port, then the internal switch is stuck.  Insert the earphone plug a few times and see if you can trip the switch.  If that fails, insert a cocktail stirrer and the like and jiggle it around inside.  If that fails, take it to an Apple store and have the technicians at the genius bar do it for you.
    Ciao.

  • I have downloaded a trial version of Dreamweaver CS6 to my MacBook. Why do some features not work?

    I have downloaded a trial version of Dreamweaver CS6 to my MacBook. Why do some features not work? I have OSX 10.6.8. I am using this trial version for a class I am taking on coding webpages using Dreamweaver. there are features I am using in class that will not open up or appear as options when I use the trial version. Are certain features locked out until I buy a copy or download a purchased copy?

    Trial versions have no functional limitations, though your setup/situation might not be supportive of all functionality.  You'll need to identify specific issues to get help with them.  You should be posting in the DW forum instead of here if your issue does not have to do with downloading/installing.
