Internal AirPort not longer showing in PowerBook

I picked up my PowerBook this evening, and wasn't able to wake it from Sleep Mode. After powering down and and powering back up the system, the Internal AirPort card now seems to have disappeared or no longer be functional.
In Network Configurations it is grayed out and not selectable, if I open System Profiler or "More Info" in the About This Mac screen there is "No information found" when i choose AirPort Card.
Everything was working okay last night when I put it to sleep. I did download updates for QuickTime and iTunes over the weekend, but I can't see how they would affect Network hardware (This does look like a hardware or firmware issue).
Any help would be appreciated,
Cheers,
Paul.

Had the same thing happen to me. Remove your keyboard carefully via the 2 hatches at the top of the keyboard. As you are looking at the exposed area, notice the orange cable to the left. Make sure that it is securely attached. Mine was loose and after pushing it back into place all has been well.

My internal speaker no longer shows as an output option; has anyone experienced this?

My internal speaker no longer shows as an output option; has anyone encountered this before?

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure Mute is not enabled.
2. 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.
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".
5. 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.
    Option click the speaker icon, if present and select Internal Speakers.

I had a MobileMe account and when Apple switched to iCloud I now have two mail accounts: @mac and @me. Additionally my folders in iCloud not longer show up in my Mail program. How do I return to one account and see my folders on my mac?

I went to Notes. Showed all notes. Three notes are duplicated, one on iCloud and one on Icloud. I deleted one of the notes and checked to see if the other still existed. It did. I deleted the other two notes. I check all notes and found that the three notes were deleted on both accounts. The only notes on this device are under On My iPad.
I went into system settings and tried to delete the Icloud account. The warning comes up: This will delete all IMAP notes on your device. Will this also delete the notes in On My iPad?

Why does my internal speakers no longer show up in my sound preferences?

In February, I updated my MBP 15" to 10.7.3. After restarting my system, the internal speakers were no longer listed in my available outputs under my sound preferences. I wasted an hour of my time talking to phone support only to hear the same stuff I had found online to try to troubleshoot the problem. Finally they told me to go to the Genius Bar. I went to my local Apple store where they proceded to look at it for about an hour and in the end told me the way to fix it would be to just wipe the harddrive and reinstall OS X. I couldn't afford to do that at the time due to needing the computer for grad school and chose to wait till after school let out to do this. Now I have wiped the harddrive twice and reinstalled and STILL don't have sound.
Does anyone have any ideas of what I can do to try to fix this?

It's a longshot, but you could try this:

My WD external hard drive will no longer show up on my Macbook pro.

My WD external hard drive will not longer show up on my macbook pro. The light turns on and you can hear it running but it won't show up either in finder or in the disk utility. This happened a while ago but I really want to get all my photos off the hard drive. Is there anything I can do to get my computer to read it again or get my data off of it?
I don't have access to another Mac to test it.
Thank you

dead sata bridge card. very common problem.
see all about it here:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
verify HD on another Mac however, if same, dead SATA card most likely

Trying to reconnect airport express to time machine but express not showing up in base station. unfortunately clicked forgot in airport utility and express no longer shows up. how to reconnect?

I would recommend setting the wireless encryption on the AirPort Express BEFORE configuring it for the AirPort Extreme in this case. This issue also comes up often when configuring AirPorts into a WDS.
If setting up security in my recommend order does not work, temporarily connect the Express by Ethernet to the Extreme; make the security changes, and then, move the Express back to the desired location.

Any change on reboot?

Two airport express no longer show w time capsule in utility

did the latest update interfere with our two airport express. i did the Mac update install and neither of the airport express show in the configuration. we also had a power outage yesterday for about 5 hours. not sure which is the culprit but after doing the install and rebooting the entire system we still have no airport express devices showing anymore under the time capsule and their lights are solid yellow.

Factory reset them.. they have stopped boot.. (solid yellow) .. it must flash yellow or when setup correctly go to green.
And yes, Yosemite has the worst airport utility and network on any new OS ever released.. ever.. I mean Vista badness.

My ipod touch 4g just updates today on itunes and the update caused more trouble than good for me. My ipod will no longer show me the battery percentage in the top right hand corner and I am not allowed to drag other applications to the bottom panel. Also my itunes doesn't allow "enable disk use" anymore. Can anyone help? My ipod now says that it's the 4.3.4 version

- Unjailbroken iPod never showed % battery. Just the icon.
- Unjailbroken iPod Touches never had a disk mode.
- What happens when you try to drag a wiggling app to a empty space in the bottom? Does it move and snap back?

Airport Utility no longer shows two AE's on the network

I have an Airport Extreme Base Station + 4 AEs' (802.11n); when Airport Utility window opened for an update, I quit in the middle of it, when i opened up the Utility today, it no longer shows 2 of the AE devices. Anyone know how to have all shown again in Airport Utility? Thank you.

Ended up being a problem between my two routers conflicting with each other. Set up two different networks in the house and now all is happy.

My ipod nano 7th gen no longer shows "Playlists" in the music menu. No changes made other than deleting one and adding one playlist to those synced. Synced fine in late February. Not working as of 3/7/2014.

I would either say that the iOS is correpted due to a software glitch or y have have a hardware problem like bad memory locations that are corrupting the iOS.
- Restore from backup via iTunes. This will install a fresh copy of the iOS. See:
iOS: How to back up
- Restore to factory settings/new iOS device.   This will elimate corruptin in the backup causing the problem.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
