Control-eject shortcut to shut down stops working?

The control-eject shortcut and the disc eject button don't work anymore on my keyboard. I recently took an upgrade to 10.4.9 and had a few issues with the 'make alias' command in my Applications folder but repair permissions fixed that.
Now I notice this but I'm not sure if it started right after the upgrade or a bit later. Anyway, any suggestions on how to apply a fix would be welcome.

Hi
They still work but you have to press the eject key for 1-2 seconds, not tap & release like you used to:

Snow Leopard cannot run on a PPC G5 Mac as it requires an Intel processor. Please confirm what Mac you have.

My iMac will not recognize a blank DVD-R that I am trying to burn. It also won't eject unless I "shut down"

My iMac will not recognize a blank DVD-R that I am trying to burn. It also won't eject unless I "shut down" and restart while holding down the mouse button. Anyone have any remedies?

I ran into a similar (identical?) problem. I inserted a DVD-R and my imac would not recognize it. The only way to eject was to do a restart. I tried some of the SMC reset stuff. That didn't work. I came across another thread on macrumors (http://forums.macrumors.com/showthread.php?t=336501)
that solved my problem.
I have an external Western Digital Passport drive that I use for timecapsule. It turns out
there are two files that WD adds to the /Library/LaunchDaemons that interferes with the
SuperDrive. I removed the WD files from the LaunchDaemons directory and everything works fine
now. Again, refer to the macrumors thread for more details.
The files I removed from the LaunchDaemons directory were:
com.wdc.WDDMservice.plist
com.wdc.WDSmartWareServer.plist
..yes I had installed the WD backup software to see if I liked it....I did not, but didn't realize this files would cause a conflict with the SuperDrive.

Purchased Lion, installed it - once I log in - i get the curtain and message to hold the power button till it shuts down. Worked with the disk repair utility - fixed permissions - still can't get past the "black curtain of death" any suggestions?

My machine was patched to date 10.x.x. I was lucky to get an internet connection and I selected the option to re-download Lion... its curruently being downloaded. What if that doesn't work?
Any thougths would be appreciated.

And you have a workstation? not a notebook.
Usually a driver or hardware, nothing that Disk utility will fix.

Running Widows Vista system, every time I try to copy and paste from Firefox DEP shuts down Word Works

I am using a HP desk top with Windows Vista. When ever I try to copy and paste from Mozilla Firefox, the DEP system shuts down
Microsoft Works Word Processor. I have tried turning off DEP for Works but it still shuts down the Program.

This is might because of your prior change in softwares. so first you have to do run '''sfc''' in run command. and then you see the specific problem which causes this . Since System File Checker (sfc) scan will make Windows replace corrupt or missing system files on your computer.
* Click Start>All Programs>Accessories>right-click Command Prompt, and select Run as Administrator.
* Click Continue or supply Administrator credentials if prompted.
* In the Command Prompt window type the following, and press Enter:
sfc /scannow

See this is not a problem of firefox till now. You can check more with microsoft answers site.

Voltage at 24 pin and 8 pin connectors are ok and under the tolerance as I saw here http://pcsupport.about.com/od/insidethepc/a/power-supply-voltage-tolerance.htm
I will check the other rails.
Hmmm... starting to suspect that the cause is something else.
Missed the beeps in the past.
This mobo (z77a-g45) never emitted a single one.
Not even at startup when it was ok!
Oh man!
The computer was running well and then suddenly screen went black, no disks activity, no keyboard response, no video, no reset switch working. Fans continue spinning.
Had to pull the plug to stop the fans. Then plug it again but no boot. Just cpu phase led 1 is lit, fans activity and nothing more. No welcome screen, no disks activity!
I will try to test the ram on another computer.
Any other clues?

Since downloading Firefox on a new Windows 8 PC I have issues with adds imbedded in websites and IE10 shutting down & not working properly.

Downloaded Firefox since several websites we use are not yet fully compatible with IE10. Since downloading IE10 will register a problem as soon as opened, shut down, then reopen to same page. Also have adds embedded in websites like Facebook that were not there previously, as well as popups from Firefox (Deal Caddy???) that I can't figure out how to disable. Also noticed that the two-finger scrolling in Windows 8 (when using IE10) no longer works correctly. These issues only exist for one of two users on this computer. The user that did not install Firefox does not have the above issues.

In order to uninstall a possibly unwanted extension, please do the following:
#From the Firefox window click the Firefox button at the top left and select ''Add-ons'', or, if the Firefox button is not shown, click the ''Tools'' menu and click ''Add-ons''.
#Once the Add-on Manager has opened in a new tab, click the ''Extensions'' button on the left side of the window.
#You should now see a list of your installed extensions on the right side together with buttons on the right side of each extension.
#To remove an extension from Firefox, simply click the ''Remove'' button. You should see a message that informs you about the successful removal of the add-on.
#Note that some add-ons require a Firefox restart to be removed completely. To perform a Firefox restart after the add-on removal, click the ''Restart now'' link in the message.
You can find further information about uninstalling extensions in the following articles:
[[Disable or remove Add-ons]]
[[Remove a toolbar that has taken over your Firefox search or home page]]

Do additional hard drives need to be "ejected" before I shut down?

I know this a total rookie question,but I just installed (2) WD Caviars(500 gb ea.)for
music(ProTools)and video,respectively.I am wondering do I need to "eject" their icons everytime
I shut down?In the past I've used external drives for the Pro Tools stuff,and ALWAYS had to make sure to eject first,before I powered down,this is the first time I've added internal drives.
Also,are these drives always spinning and "on"?The external drives had an on/off switch.
I would like to save power/wear and tear/ and not have these running when I'm not using them.
Any advice would be greatly appreciated

The only time you need to eject a drive is if you are going to disconnect or turn off the drive and keep the computer running. If you shut down (not just sleep) the computer, it dismounts (ejects) all drives, so it is safe to disconnect or turn them off after the computer has shut down.

G4 shuts down while working on it.

hi
My G4 mdd lately has been shutting down for no apparent reason. I'll be working on Photoshop, web surfing, etc. and the G4 MDD will just shut off. I read a lot on the MDD having PSU and/or overheating issues. What can I do? Are there fixes for my good ol G4 MDD? Are there PSU replacements that will work?
web dude

A hot temperature can cause a shutdown. Suggest you download & install the freeware Temperature Monitor http://www.macobserver.com/tmo/review/temperaturemonitor_4.6_gives_warmfuzzies/

Why does clipboard from FF shut down Microsoft Works?

Any idea why clipboard contents copied from a web page in Firefox, would not paste into Microsoft Works? I can paste to Notepad or Wordpad, but if I try to paste to Microsoft Works, the Microsoft program shuts down every time. I can, however, paste from IE to Microsoft Works, so it seems to be a Firefox setting somewhere, but I can't figure out where.
== This happened ==
Every time Firefox opened
== I first downloaded Firefox

Use "Edit > Paste Special" in MS Works.

Temporary shut down of Work Center

We are taking capacity planning into consideration, and work center is
temporarily shutdown for a period of 12 hrs.
How to capture the temporary shutdown of the work center in SAP, in order
no production orders takes work center into consideration as available capacity during this temporary shut down time
Lastly, if shutdown time is able to capture in SAP, and fixing of work center
is less than 12 hrs (lets assume 8 hrs) How to chance dynamically in orders for the production orders
to consider the work center as available

Thanks for your inputs
We have not implemented PM module. As a work around, we created a
dummy production order (without material - c007) and assigned a operation to the
temporary shutdown work center, this production order filled the work center
temp. shutdown time slot (so, other production orders cannot use it)
Other Parameters we considered:
1. Backward Scheduling
2. Basic Finish Date (day on W/C is temp. shut down)
3. Basic Start Date calculated (From Routing Operation Mins)- Routings operation
minutes maintained in par the temporary shut down time
4. Operation costs: 1cent/hr

System sleep and shut down not working after upgrade to windows 10

HiI upgraded my OS from win 8.1 to win 10.After the upgrades the system shutdown and sleep are not working properly.It's like when I shutdown/sleep the system ,the screen shuts down but the power key keeps glowing and also the battery keeps draining.So eachtime I have to foercefully press the power button to shutdown the system. I have updated the display driver . Please someone suggest, what to do ?

Hi there , Thank you for visiting the HP Support Forums and Welcome! I read your post on the HP Support Forums and seen that you are having issues with your HP Pavilion 15-n260tx Notebook PC and the Sleep/Shut down options. It sounds like you might be having an issue with one of the features of Windows called Hybrid Shutdown that is used for the Fast Startup feature. Here are a couple of links for you about Fast Startup, Hybrid Shutdown and How to Shut down your Notebook completely. They also have some troubleshooting steps in them. 1. Fast Startup - Turn On or Off in Windows 10.2. Shut Down Computer in Windows 10. If those do not work, I do have some more documentation for you to read and try. 1. Shut down (turn off), sleep, or hibernate your PC - This document is from Microsoft. 2. HP Notebook PCs - Managing Power Options (Windows 8)3. HP PCs - Sleep and Hibernate Issues (Windows 10, 8) Sometimes a BIOS Update will work. You can update all of your drivers by going to the HP Driver's website or by using the HP Support Assistant. On the Driver's page there is not an update for the Windows 10 Column, but there was an update that just came out under Windows 8.1 on Aug 7, 2015 that should work for your Notebook. Another fix that may work is to Run the Troubleshooter. Please follow this link to run the Windows Update Troubleshooter. I hope this helps! Have a great day!

2011 MacBook Pro shuts down while working with blu ray disks

I am trying to backup my blu ray disks to digital formats in the event that a disk is damaged. I am using an early 2011 MacBook Pro with OSX 10.8.5 with a Samsung SE-506 external blu ray writer. I have been using handbrake to rip DVD's, but downloaded Make MKV to handle blu rays. I successfully ripped one blu ray disk last night. Once before that, and four times after, the computer shut down after failing to read the disk. When it restarts, a gray screen reports that the computer experienced and error and had to shut down. I believe this has something to do with the fact that OSX does not natively support blu ray disks. The disk drive is plugged into one of two USB slots in the computer. The other slot has a USB hub with two external hard drives and some other devices connected to it.
So far, the computer has failed to recognize the disk, and nothing comes up in Make MKV. The last time I tried, the computer recognized the disk, Make MKV read it and showed the titles. When I tried to rip the disk, the process failed. After another attempt, the computer shut down. This has never happened while using the original disk drive, or while using DVD's in the external drive.
I spoke with Samsung support, and they have no record of this being a problem. So, where do I go from here? I have quite a few disks to rip, so I am hoping this issue can be resolved. I have searched around, but cannot find any information on this problem happening to someone else.

Why does my mac book air just shut down when working

When using my mac book air it just shuts down. I usually need to tap several keys to restart. Any help?

If you mean that it just shuts off without any warning, then this might help:

Otherwise it needs to be fixed.
