Currently Being ModeratedMar 9, 2009 12:07 PM (in response to alanwu008)Exact same problem for me. I've seen similar problems in other threads that have come and gone without reply.
My problem is that if I close my laptop when XP is running, it will (more often than not), get hung up on the "Preparing to Standby" screen (without actually going into Standby mode ... often getting my machine very hot in the process). If I run on battery power and leave long enough for it to go into Standby mode on it's own, it simply hangs on that screen, with my only option to hold down the power key to shut it down.
Anyone out there know why?iMac G4 - 17 / MacBook Pro (Penryn 2.4), Mac OS X (10.5.2)
Currently Being ModeratedApr 1, 2009 12:30 PM (in response to alanwu008)Having an issue not quite like either, but something like this. I may start a new thread as I have not been able to find this problem anywhere in the discussions. I can run windows fine, but when my MBP goes to sleep (I guess) in windows, I get a black screen and it won't wake up. I have to power down and restart to get anything. Then today I thought I had powered it down after this happened, and when I pulled it out of my bag 20 min later, it was hot and the fan was running continuously. Have you guys seen anything like this, personally or in a thread somewhere ? Let me know, I'll be watching this thread. Thanks Steve

Currently Being ModeratedApr 21, 2009 1:27 AM (in response to Max Tomassini)This is happening to me as well. I can't remember if I could sleep and wakeup properly previously (I don't use boot camp too often on my first gen MBA), but it's been hanging and heating up once I close the lid lately.MBA 1.6 HDD, iMAC 17", Mac OS X (10.5.2)
Currently Being ModeratedMay 20, 2009 11:22 AM (in response to tcwan)I have the exact same problem using a MacBook Pro
1. It won't go into standby.
2. It won't go into hibernate
The problem recurs constantly.
There allegedly was a solution on this page:
But it is no longer accessible.
I am concerned for the longevity of the computer.
Also, it raises all kinds of issues ranging from overheating of the unit to safety of its operation.MacBook Pro, Windows XP Pro
Currently Being ModeratedMay 20, 2009 11:26 AM (in response to opodder)I did find one clue, that the running of certain programs increased the likelihood of the standby problem to occur. However, even without that program running, it now occurs constantly.MacBook Pro, Windows XP Pro
Currently Being ModeratedJun 7, 2009 6:57 AM (in response to alanwu008)I had this problem reported by several others here. I fixed it yesterday by disabling (within Windows XP Pro SP3) the Apple OS Switch Manager service called AppleOSSMgr.exe. Now standby, hibernate, restart and shutdown all work fine, multiple times. If you are not sure how to disable a service in Windows, read the advice here: http://www.overclockersclub.com/guides/windowsxpservices/Macbook Pro, Windows XP Pro
Currently Being ModeratedJun 11, 2009 6:43 PM (in response to databassist)Unfortunately disabling the Switch Manager service did not fix the problem for me. I've been having the same symptoms as others on this thread with my MB Pro.MacBook Pro, Mac OS X (10.5.7)
Currently Being ModeratedSep 7, 2009 9:03 PM (in response to wayt)I can go into standby fine, but about 75% of the time, I can't wake it up (screen stays black no matter what you do until you force a power off and turn it back on). I would very much like to know how to fix this. Anyone at Apple read the forums? If so, we sure could use some advice! Thanks.

Currently Being ModeratedSep 23, 2009 9:02 PM (in response to sean2078)Same problem here, the computer can go in sleep mode, the power light flashes slowly, and hard disk stops. BUT!Q But but but when I press a key to wake it up, everything but the screen seems to wake up.
I've tried disabling the OS Switch Manager, checked and unchecked "password Required", even reformatting XP since it was a new computer. No,luck, and no further ideas. Same thing with BootCamp 2.0 and 3.0. (I upgraded to Snow Leopard) to get the latest drivers.
Sometimes, when I play with the power options, I can get the screen to turn back on but the mouse (and everything else) freeze about 20 seconds later...and then I have to do a hard restart.
Anybody encountered this problem?
And most importantly, anybody fixed it?Macbook 4.1, Mac OS X (10.6.1), Windows XP
Currently Being ModeratedSep 29, 2009 1:07 PM (in response to scarer)Yessssssss! It works!!!!!!!
I had the smae problem. When waking up from stand by, XP screen would be completely black, or turn back on for a few seconds with artifacts on the screen, before freezing again, thus needing a hard reboot by holding the power button for a few seconds.
*Here's how I fixed it* : *Disabled Bluetooth radio in device manager*.
+chriswilliams : "i had this same problem on my old macbook pro, the solution i found was turning off the power management for the apple built in bluetooth device in computer management in XP, try it and see, it works for me" === found on === http://discussions.apple.com/thread.jspa?messageID=8672991+
So! To do this:
- My Computer
- System Properties
- Device Manager".
Then right-click on the bluetooth devices and click disable on the Bluetooth radio if you never use it. It worked for me.
IF YOU USE BLUETOOTH, try to just disable the power management options of this device. It might work just as well, but I didn't test it.
I hope it helps.
Thanks chriswilliams and everyone on the forum!Macbook 4.1, Mac OS X (10.6.1), Windows XP
Currently Being ModeratedSep 30, 2009 5:44 AM (in response to alanwu008)fwiw,
i have the same problem on a fresh win xp bootcamp install (windows updates installed as well). After initiating stand-by the screen goes black, backlit keyboard still on , and fan still spinning. need to force shutdown to get out of this.
I tried disabling the bluetooth and the Apple OS Switch Manager, but this didn't resolve the problem for me.MacBook5,1, Mac OS X (10.6.1)
Currently Being ModeratedSep 30, 2009 6:16 AM (in response to SebastianV)Hi,
I seem to have fixed it at least for my case. Here is how:
I went to control panels -> Administrative Tools -> Event Viewer -> System
There i saw an error listed caused by "nv" which happened during attempting to go into stand-by. Here the description from the log:
" The driver nv4_disp for the display device \Device\Video0 got stuck in an infinite loop. This usually indicates a problem with the device itself or with the device driver programming the hardware incorrectly. Please check with your hardware device vendor for any driver updates."
I checked with Nvidia and downloaded their latest driver package
( used Option 2 to automatically detect the graphic driver)
Installed, rebooted, and now i can get in and out of stand-by mode. Wohoo!
Hope that helps someone else as well
