Keyboard lights up but won't work

Hi
I have a 2010 13" MacBook Pro with the 2.66GHz processor and 4gigs of ram. Yesterday when I was using it, the screen went yellow and the fan started spinning quickly so I turned it off. Now when I restart the computer, I get to the login screen, and the keyboard is fully illuminated but I can't type anything or move the cursor with the trackpad. Even my apple wireless keyboard and magic mouse won't work even though they normally would at that login screen.
I tried doing the apple hardware test and it said that there was no problem. The fact that I was able to hold down the 'd' key and get it to start the hardware test shows that the keyboard isn't broken, so I don't know why it isn't working.

HP Optical PS/2 Mouse - Light On But Won't Work

Hi, I am hoping someone can help me out. My current ten year old mouse is starting to have difficulty with clicking, so I am trying to replace it with a HP mouse that I have. For reference, this is the new mouse: http://www.amazon.com/HP-GM278AA-ABA-M-SBQ133-5188-6230/dp/B000UH0OD6
I plug it in, but it won't move the cursor or click anything. The light on the bottom of the mouse comes on, but nothing else. When I go to the Control Panel it doesn't list it under mouse hardware, either. I have a Windows Vista.
Thanks!

Hello KrisML,
Hopefully your new mouse was not sold used as is in that amazon ad you referenced.
Can you connect it to a different computer to see if it works on it or not? If it does work...
Its possible the driver installation for the new mouse is corrupted and needs to be removed in order to reinstall again.
You can safely remove any usb drivers that are not in use (hidden drivers). Devices that get plugged in later will simply reinstall its needed driver again.
Remove the mouse from the computer if it’s attached and use the mouse that does currently work (unless its a laptop).
Right click Computer and click on Properties. In the System window on the left side, click on Advanced System Properties.
Choose the Advanced tab and click on Environment Variables… button at the bottom.
Under System Variables, click on the New… button
Type this in the box that pops up.
Variable Name: devmgr_show_nonpresent_devices
Variable Value: 1
Click OK on all the open windows to close them out.
Go to Computer Management again and click on Device Manager. Go to View at the top of the window and click on Show Hidden Devices.
Click on the drop down arrow for Mice and other pointing devices to open the list.
Look for any device listed that is hidden (greyed out) and delete it.
Click on the drop down arrow for Universal Serial Bus Controllers to open the list.
Look for any USB Composite Device that is hidden (greyed out) and delete it. There may be several and it’s ok to delete them all.
It wouldnt hurt to do the same for any USB Mass Storage Devices also since they will just reinstall once connected again.
When you connect the mouse to the computer again, give it a minute to reinstall the driver.
Let me know if you have further questions.

My keyboard lights up but doesn't work at all except for the on button.

Greetings
I just purchased the late 2013 macbook pro , new Mac user here and I was loving it until a few moments ago
Basically my keyboard is lit and everything "appears to be working"
But neither the keyboard or keypad is responding at all , the only thing that works is the on button
But that's no help because the on button seems to put my Mac only on standby as opposes to restarting it completely like on windows
What should I do ? Why are all of the buttons unresponsive except for on ?

Apple TV2 airplay audio (via Airport Express) works well with music, but won't work with any video.

I have an ATV2 and Airport Express connected to speakers all connected to the same network. It all works with music, but won't work with any video audio. In my ATV's settings I've selected my AirPort Express speakers. It works for music, why not everything else? Is there a fix or work around?

Netflix is first on that list...What I mean is, if there is a feature that allows for a wireless audio connection to the Apple TV, why wouldn't the developer allow it. To keep me from enjoying a more convient connection? I can have the same listening experience on a wired connection...

TWRING,
Help has arrived! Since the device is currently on pre-order when processing the order online it will only recognize the line eligible. Once you receive the device you may activate it on another line if needed.

HT4557 I have iPad 2 and trying to connect to apple tv. Have gone into videos and music and put in my apple id and password but won't work. Pick up my PC fine though

I have iPad 2 and trying to connect to apple tv. Have gone into videos and music and put in my apple id and password but won't work. Pick up my PC fine though.
Any ideas? Have tried usual switching on and off again but no change

Here’s what you need to do to turn on AirPlay Mirroring on your iPad 2:
– Have iOS 5 installed on your iPad 2
– Make sure your Apple TV software is up-to-date. You can check for updates on the Apple TV by going to Settings > General > Update Software.
– Have your TV turned with Apple TV active and showing.
– Double-tap the home button on the iPad to bring up the Multitasking Bar.
– Swipe to move to the left of the Multitasking Bar, so you can see the set of controls just to the left of the volume adjustment slider.
– The button just to the right of the Fast Forward button – the one that has a rectangle with a solid, upward-facing arrow in it – is the AirPlay button. Tap to switch from iPad to Apple TV.
– Once you do that you’ll see the Mirroring section appear just below the entry for Apple TV. Just tap to turn that On, and the iPad 2 will immediately begin mirroring to your TV screen.

I bought an unlocked iPhone 5s from USA and travel back to my counry but won't work in my country

Well, there is nothing anyone here can do for you. Did you actually purchase it at an Apple Store, or at another retailer like BestBuy, HH Gregg, a mall kiosk, T-Mobile, AT&T, etc?
The ONLY source for unlocked iPhones in the US is Apple. If you purchased it anywhere other than at an Apple Store, you purchased a locked phone.
You can call AppleCare and give them the serial number of the phone to confirm the status of the lock.

I spilled coffee on my MacBook. I dried it for 24 hours. It turns on, the keyboard lights up but the screen is blank. Any help?

Blackberry Q5 keyboard lights up but screen stays black!

When I unlock my Blackberry (Which by the way I only got three days ago) when I haven't used it for 10/15 minutes, the keyboard will light up but it won't unlock? But if I press and hold the power button it will let me shut down or restart the device but it won't take me to the main menu, it either stays black or you get the shut down screen. Anyone know what's going on at all? It's annoying me because I love this phone, it's just this one problem! Thank you in advance!

Try this:
Go to Home screen
Swipe down to get to SETTINGS
Select DISPLAY
Make sure brightness slider is at appropriate level-- I keep it a bit nore than half way.
Make sure ALLOW GESTURES WHEN LOCKED is ON
Make sure ALLOW POWER BUTTON TO UiNLOCK DEVICE is ON
Hit Back arrow (<) and close Settings.

Caps Lock lights up but doesn't work in Mac OS (but does in Windows)

My Caps Lock button lights up but caps do not work in any Leopard programs. If I hold down the Shift key then caps will work.
However, I have Parallels and caps lock DOES work when running Windows.
I checked the Modifier Keys settings in keyboard preferences and they are set to the default.
I am new to Apple and have a Mac Book Pro that I bought in Spring 2008.
I searched the discussions but didn't see my situation...

Hi Steve, Welcome to apple discussions.
Hmm, that is a strange problem. Well, you've already done what I would suggest which is to go to the keyboard settings and click the "Restore defaults" button in the modifier keys window and try again. If that doesn't work then you can restart the computer and check. If that doesn't work you can try to reset the pram. Hold the optioncommand+PR buttons after you hear the startup chime, it should chime again, I let it chime a third time just for good measure and see if things look better.
If that fails then you can try making another account and seeing if the caps lock works in the new account. There might be some strange error on your account that would be corrected for in a new account. After that it gets more labor intensive. Do a system re-install, do an erase and install.
You might consider a trip to the apple genius bar there in Honolulu if can. The should be able to run through all that for you. You're still under warrantee so take advantage and get some help.
Oh, and just a disclaimer that I learned from Adam on the maccast podcast. Make a full, complete backup including a time machine and bootable (like superduper or carbon copy cloner) disk before you do any of the above or take the unit it for service.
Hope this helps.

Setting Keyboard Shortcuts for Services won't work

I've tried to set Keyboard Shortcuts for Services like "New Terminal Tab from Folder" but it won't work. I even tried it on my friend's machine to no avail.
Here's where I'm setting it up. And yes, I've turned on the checkbox & set the shortcut I want. I've even tried a few different keyboard shortcuts that are complicated to ensure that it's not competing with something else.
To note, I'm using TotalFinder but my friend, whose machine I tested this on, doesn't.
We are both running 10.8.2 on the latest MacBook Pro with Retina Display, 15".

I have a similar scenario......except my services that I created run one time, and then won't run again.
For example, I created a service to open a new blank email message for me to type in. I assigned Cntl-Opt-Comm-M to this service. I hit the key sequence and it works the first time.....the mail window pops open.
If I then close the mail window that it spawned and do it again, no mail window opens.
I also did this to create a blank Calendar event and also another one for Reminders.
They all run one time and then not again.
Any ideas?

Airport Extreme appears to be ok but won't work

I have my airport extreme hooked up to my cable modem and am using it as a router. It has worked fine for over a year I have had it but, for some reason has craped out today. Nothing has changed, no updates nothing. Internet is fine (if I plug the Ethernet cable directly into my MBP. Green light is on on the extreme. Have reset SSID and password and restored the Airport Extreme and the internet just won't work. Any ideas?

Hello, hfred.
If I understand correctly, you can access the internet via an Ethernet connection to the AirPort Extreme but not via a wireless connection. Is this correct?
Connect the computer to the AirPort Extreme with an Ethernet cable. Open AirPort Utility, which can be found in the Utilities folder (located inside the Applications folder).
Your AirPort extreme should appear in the sidebar. Click it, then press "Manual Setup." Enter the password if asked.
Go to the Wireless tab. The wireless mode should be set to "Create a wireless network." Ensure the wireless network name is correct.
For now, disable wireless security. This will simplify the process of diagnosing the connection, and you can (and should) re-enable it afterward. (If you have not been using any wireless security, I strongly recommend that you enable it once the problem has been solved.)
Press +Wireless Options…+.
+Transmit Power+ should generally be set to 100%.
For now, don't create a closed network. If you want, you can make the network "closed" after the problem has been solved.
Press OK.
Go to the Access tab. Disable MAC Address Access Control.
Press "Internet" in the toolbar.
Set +Connect Using+ to Ethernet. Set +Configure IPv4+ to +Using DHCP+. Set +Ethernet WAN Port+ to +Automatic (Default)+. Set +Connection sharing+ to +Share a public IP address.+
Press Update. Allow the AirPort Extreme to restart. Unplug the cable connecting your computer to the AirPort Extreme.
After the AirPort Extreme has restarted, choose your network name from the AirPort menu. See if you have internet access.
Does this work?

PDFMaker loads but won't work in Word 2013 - Acrobat XI and DC - Win 8.1 Pro

OK, I opened a question that never got answered and it never was resolved...
Just updated to Acrobat DC - same problem exists...
I'm running Windows 8.1 Pro fully up to date..
I've uninstalled and reinstalled Office 2013 Pro (I have an Office 365 subscription so it's the click-to-run install).
I've uninstalled and reinstalled Acrobat Pro DC.
I've rebooted (a full restart, not Win 8's fast boot restart) between each installation.
I've tried this in multiple Office applications, none of them work EXCEPT for Outlook.
For the following I will use Word as my examples...
I've uninstalled all plug-ins and still it won't work.
I've tried running Word as Administrator.... still won't work.
OK... so this is what it looks like... as you can see the toolbar loads, but no icons...
https://www.dropbox.com/s/wsbs4kon3z4e965/Word%20Acrobat%20Screenshot.jpg?dl=0
When you click on those buttons... it goes through the motions as if it were creating the PDF... but no file is ever created...
If I right-click on a Word document and select Convert to PDF - it goes through the motions of creating the PDF, asks me where to save... and then a dialog box named "Acrobat PDFMaker" comes up saying " {Exclamation Point Yellow Triangle Icon} An unexpected error occurred. PDFMaker was unable to produce the Adobe PDF."
If I right-click on a text file... and select Covert to PDF, it immediately pops open a PDF of the text file. Same with any image file.
This was all working perfectly up until out of nowhere it stopped working on January 26, 2015. See my original posting here: Acrobat XI Pro Word 2013 add-in stopped working
I can Print to PDF using the PDF Printer without any problems.
Creating a PDF in Outlook, no problems...
I'm hoping somebody can figure this one out... I'm completely stumped.... and I'm usually very good at troubleshooting stuff.

Click to Run according to Microsoft:
https://technet.microsoft.com/en-us/library/jj219427.aspx
"Click-to-Run is a Microsoft streaming and virtualization technology that reduces the time that is required to install Office and helps you run multiple versions of Office on the same computer. The streaming technology enables you to download and begin to use an Office product before the whole product is installed on your computer. The virtualization technology provides an isolated environment for Office to run on your computer. This isolated environment allows you to run the latest version of Office side-by-side with an earlier version of Office that is already installed on your computer."

Had upgraded to lion. Many software wouldn't work and downgraded back to snow leopard. Now it comes up c user name and password. I haven't used my password since I bought the computer years ago. I put it in but won't work. More than 8 letters, does thaMA

I upgraded to lion and many software didn't work. Downgraded back to snow leopard and now my initial login page
Is asking for my password. I put it in, but it's not working. Possible I have forgotten the correct one considering in think the last time I logged
In was when I bought the computer. But I think it's right. I did read something about if ur password was 8 characters or more it won't work? Anyone know? Or know how I can reset my password?

PS downloaded via CC seemed to download fine but won't work. Won't even open a file/document.

I recently got a new computer and I have CC so I downloaded the CC app and downloaded LR and PS. LR runs/works fine. PS seemed to download ok but won't even open a new file:picture. I am very frustrated as I have spoken with CC tech support and they were of no help, in fact that didn't even have a clue how to navigate Windows 8! I have been working on this for a week and now very behind on my editing. Not sure who to call or what to do. Please help!! Thank you!!!

What does the crash report say about the name of the faulting module?
Yes, crashes like that are usually due to the video card driver. (though I was guessing from the original description that the image was just not drawing)
Have you tried disabling GPU drawing in Photoshop before opening a document?
Have you updated your video card driver from the GPU maker's website?
