Unplugging power cord stops Windows?
Hi,
When I unplug the power cord (when the machine is in a port replicator) Windows stops responding. Does anyone know what can cause this and how to resolve the problem?
Regards,

machine model? xxxx-xxx? w500, w510, w70x?

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
1. AppZapper
2. AppDelete
3. Automaton
4. Hazel
5. AppCleaner
6. CleanApp
7. iTrash
8. Amnesia
9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless. -

Macbook Pro: both external screens go off when unplugging power cord
Hello!
I have my Macbook Pro set up with two external screens one connected thru HDMI and the other with Thunderbolt, I keep the lid always closed. I always have the power cord plugged in but when I for whatever reason unplug the cord both screens go dark and don't seem to "wake up" anymore. When I plug back in the cord I have to open the lid first to make the login window appear but after login my screens are switched. When I close the lid again it goes back to my original set up. The same when I turn on the Macbook and don't close the lid after it right away, the screens are switched until I close it.
Any idea on this?As this article points out, there are very stringent requirements for using a MacBook in "closed clamshell" mode. #1 is to have the power adapter plugged in:

IBook screen goes black after unplugging power cord
I originally posted this topic in the wrong discussion group for iMac G4, the computer is actually an iBook G4.
My wife's iBook bought about 2 years ago shows battery 100 percent charged. But when she unplugs the power cord the screen goes black. Can not be restarted until she plugs in the power cord. It seems like it might be the battery. She got extra batteries when she bought it. Is there a way to tell if it is the battery before having to replace it?Did you check on the status of your battery using "About this Mac" under the Apple on the menu bar? Click on "More Info..." and select Power under Hardware. It will tell you capacity and cycle count.
You may have a dead battery.

Ipad power cord stops working after a few months
I have had my ipad for about a year and a half and have gone through four power cords. The adapter/transformer is not the problem it is the cord itself. I have used only apple charging cords bought from apple. I don't let kids plug it in or unplug it so that the cord doesn't get damaged but it nothing I do seems to help. Could it be a problem with the ipad itself?
Sounds like the router firmware needs to be updated or the router replaced with a newer one.

Won't boot up unless I unplug power cord first
After shutting down my iMac, if I leave the power cord plugged in like overnight, I cannot boot up. It sounds like the computer is already on because I can hear the fans whirring and hear a click, but I do not get the ping and the screen stays black. But if I shut down the computer and say within 5 minutes try booting up again, there is no problem. I took it into the Apple Store once and they kept it for a week but they said they could not recreate the problem. Is there a problem with unplugging the computer after shut down every time. I am still under warranty until December 2010.
Hi, 2 ideas:- (1) go the SMC & PRAM reset route. (2) Take it to your local Apple Approved Service Agent..

Macbook shuts off instantly when I unplug power cord.
Hello everybody.
This afternoon while I was watching a movie on my macbook, (it was on battery power, about 3/4 full) it just shut off. I could not turn it back on, so i plugged the power cord back in, it turned on fine, but whenever I unplug it it shuts down, even though it recognises the battery and charge level and all.
The thing is, when it shuts down it's not like if there was no battery, the screen dims, the battery icon changes to the one it has when its on battery power, and about 1-2 seconds later everything just shuts down. I'm just out of warranty (about 2 weeks ago). Do you guys think this is a hardware issue? I've gone through all the updates i have found on batteries and even reset the power management thing (where you turn the computer off with no battery and hold the power button).
Thanks for any help

PB freezes when unplug power cord from laptop but not power outlet
Hi. Been having a dilemma with my PB for awhile. When I unplug the power cord from the connection in the PB, my laptop will work fine for a few minutes but always freeze at some point. By 'freeze' I mean the cursor will not move and the keyboard, trackpad, etc will not respond at all. I can restart it and continue to work until it will (always) freeze again. Strangely enough, if I unplug the power cord from the wall outlet but leave it in the side of the PB, I don't have any freezing problems. I'm not that savvy with Apples yet since I made the switch but I've tried resetting the pram thing but to no avail.
Any suggestions?
Thanks!

MBP dies when I unplug power cord
Anyone have any ideas? The battery wasn't in the best shape, it had "check battery" for about a year now.
Of course, Apple refused to do anything for me, as it's out of warranty. Until last week I was getting maybe an hour out of it. But ever since upgrading to 10.5.7 last week, as soon as I disconnect the power-cord, 1 sec later, the laptop just dies, requiring a reboot.
Tried resetting PRAM and the PMU/SMC. Reinstalled 10.5.7.

Why did you wait so long for help?
Try the following:
HD/System/Library/SystemConfiguration & look for a file called batteryupdater.bundle. Select Get Info for the file.
If its version number is 1.2 or 1.3 you should be fine If not, or if you cannot locate a batteryupdater.bundle file (by using Spotlight, searching manually or using a 3rd party search feature) then download an update from Apple's website & install it. *If installing has no effect, you probably need a new battery.*
Your battery may be replaced for free. Take your computer to an Apple Store. _The staff will be able to check to determine if your model MBP qualifies for the free battery program._

Radius sleeps after unplugging power cord
After my Radius is fully charged, when I unplug the power the laptop will immediately sleep. When I wake it up, it runs fine for hours on battery, as expected. Why on earth does the laptop sleep when unplugging the power?
It's really inconvenient because if I'm playing music while it's charging the music stops when the laptop goes to sleep after I unplug it!
I cannot seem to find the right series of options in the power control panel to prevent the laptop from immediately sleeping when I disconnect the power cable.
Please advise.If you can't solve your issue and no one in the community can help, contact support to speak with a tech support agent at (800) 457-7777.

I have a Power Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power on/off button again. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Sometimes my Mac goes on just by pressing the power on button but most times I have to pull the power cord and put it back in. Any ideas or help out there for this? Could it be a failing power supply? Apple Care says that this model is obsolete so there is no help from there. John
<E-mail Edited by Host>Hi John,
That's often a sign of a bsad Capacitor in the Power Supply, but...
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...
