Windows 7 on imac 27 not waking up properly

Hi,
I have an imac 27 , I've installed windows 7 on it. There is one bug that is persisting no matter what I do.
The machine works all fine except on wake up from sleep it often(>70%) crashes.
I have tried the following
1) installing windows 32 bit versus 64 bit, no change
2) installing win 7 only (removing mac OS and no boot camp), no change
3) tried to flush PRAM as described in other articles
4) tried it in safe mode
5) removed 2G of 4G memory for both of memories
Any insight is appreciated....

HI and Welcome to Apple Discussions...

IMac not waking up

Hello everyone.
For some reason my 27" late 2012 iMac is not waking up properly. This seems to be since upgrading to Yosemite 10.10.1 - it never happened on vanilla 10.10.
What happens is this: I'll come back to my Mac for the first time in the day having left it asleep the last time I used it, and find it won't take at all - nothing happens on touching any keys or clicking the trackpad. Even pressing the power button does nothing - it might as well be off, if it weren't for the fact that pressing the power button if it was off would at least turn it on. The only way I've found to bring it back to life is a hard reboot by pulling the IEC out of the back, which is really something I'd obviously rather not have to do every time I want to use my computer.
I has assumed this was an issue with not waking from sleep, so yesterday after using my Mac I disabled computer sleep and just put the display to sleep, but today when I came to use it once again I was greeted with an unresponsive blank screen.
I've never had this sort of problem before so I'm not sure what troubleshooting steps to try.

Hello Rob!
Apart from the update to 10.10.1, did you install anything else? If you have the chance, test from Safe Mode without any applications open:

MacBook Pros Not waking up properly even after clean re-install

I just bought a used 17" Quad core MBP with 16gb of ram. I installed a samsung 512gb 840 Pro series SSD, transferred all my info from my old dual core i7 17" MBP. So both are 10.8.4.
The new MBP started not waking up from sleep. The keyboard would like up and the light in the front would indicate that it has started, but then it doesn't show anything on the screen.
Ultimately, I decided, i'll just do a clean re-install of OS 10.8 because maybe something went wrong in the migration. Now, with a fresh install when i wake it from sleep it seems to open as if it ran out of power and is doing a restore power up. The screen opens at half opacity and I get some progress dots and its back quickly. But it's still strange. The only thing installed on the computer at all is adobe production suite.
Odd thing is, that the OLD computer, the DUAL core i7 17" MBP is also not waking up from sleep properly now. It also has a new 128gb SSD drive It BTW. It doesn't fully wake up, so I have to hold down the power button, shut it down then turn it back on again. And again it does a recovery startup.
so now I have TWO computers having almost the same issues, and one of them has a fresh install. So what could the problem be? totally diffferent hardware. Does 10.8 not like SSD's in 17" MBP's?
any tips would be apreciated.

One last detail, connectivity through my iPhone's hotspot works completely fine. No idea if that is related / helpful in any way.

Why does my intel iMac not shut down properly?

On Shutdown, the screen goes black, appears to be shut down, but start button will not start unless you hold it in for several seconds. After machine boots messages says not shut down properly. Does this everytime. Has done it since it was new a year ago. the screen is black, but the button will not start the machine unless you hold it down, then you get the message. Have never seen anything like this. It is as if the machine thinks it is still running.

I'm not sure that a normal shutdown followed by turning off a power strip will reset the SMC. Power strips just switch off the "hot" leg of the power but do not interrupt the "cold" (neutral) leg or the "earth" (ground) connections. It may be that the SMC senses the cold-to-ground path or something like that to do a reset.
It may also be that the Mac hasn't actually shut down completely when you switch off the strip. You might try waiting a minute or two before doing that to see if it makes a difference, or listening carefully for any noises coming from the Mac after the menu shutdown before hitting the power strip switch.
I sometimes use an old veterinary stethoscope to listen for sounds coming from Macs for troubleshooting purposes (although never yet with a MacPro) & have noticed that the screen goes dark a little before everything else is fully shut down.

Can iMac not waking from sleep be caused be a corrupt file

I have had my 27" iMac from July of 2011 (running Montain Lion, 8 GB RAM, 2TB hardrive, 3.4 GHz,Intel i7) for over a year and a half and ever since I bought it, it has had a problem waking from sleep. I can hear the computer running, but when I click the mouse, keyboard, or power button, it stays asleep and I am forced to do a hard shut down. Apple has been trying to fix the issue, but to no success. They have replaced the hard drive, logic board, usb ports, RAM, mouse and keyboard, but it still happens. They finally threw in the towel and are replacing the machine. They offered to transfer all of our files (jpgs, mp3s, docs, videos, etc), but one thought occurred to me... what if the sleep issue is caused by a corrupt file? I highly doubt that is the case, but wonder if any of the experts out here would know better than I.
If we didin't have the data transfered, we would just keep it on an external hard drive instead. But, I would assume that it wouldn't matter if the files were on internal vs. external because either way, the computer would access the files. That being the case, if the sleep issue was caused by a corrupt file, the computer would still access it on the external and the sleep issue would resurface.
So, 2 questions:
Can a corrupt file cause the sleep issue?
If it is true that a corrupt file can cause the sleep issue, would it matter if the corrupt file was accessed from an external drive vs. internal drive?
Thanks so much!
Chris

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

24" iMac not waking up

I have a 24" iMac that's been great until the recent EFI update. When it goes to sleep I can't wake it. I have the wireless MM and kb, and they woke it before. I even plug in a usb mouse and keyboard, or hold the play/pause button on my front row remote, and nothing can wake it... I always have to resort to powering it down and restarting it. but then I have to repair permission and such, which takes forever with a 3/4 full 500GB drive. It doesn't always refuse to wake up, but more times than not, I have to recycle the power. I suppose I can prevent it from going tro sleep altogether... but for a nearly $3000 machine, it would be nice if it worked properly.

FIXED IT!! I did some research on other posts. Basically all you have to do is shut down your computer. Pull out the power cord from the back of your imac. Pull out all other cables (keyboard, upc)... Wait 15 seconds and replug. You should be fine. Then reboot.It fixed my problem. Here are the details that I got from the other board:

Try a simple SMC reset. The SMC (System Management Controller) controls all the power functions of your machine including telling the computer when to turn on, turn off, sleep, wake, idle, and so forth.
You can find a detailed explanation on what the SMC does and how to reset it here: http://docs.info.apple.com/article.html?artnum=303446

Imac not waking

Not a question but hopefully an answer to what seems to be a common problem.
I have just taken delivery of a shiny new imac running Mountain Lion. I migrated software and files form my old imac without problem and reconnected all devices.
I found that when the imac went to sleep, nothing I did would wake it again, part from pulling out the power lead and putting it back in. I read about CMS resets and did that. Nothing doing.
So I rang Apple Care as the machine is still in its 90 day free support period. I spoke to someone called Tom who was extermely patient and helpful. He quickly identified the problem as something to do with attached hardware. By a necessarily long-winded process of elemination, we identified a USB hub as the source. Admittedly, it had worked fine with my old imac but the sleep process and waking, coupled with the optional Fusion drive installed in my machine, seems to work a little differently, and clearly does not play nicely with certain peripherals.
It probably won't solve everyone's problems but it might solve some.

WINDOWS ON IMAC NOT DETECTING INTERNET CONNECTION

I RECENTLY LOADED WINDOWS XP ON MY IMAC AND THE INTERNET CONNECTION IS NOT WORKING, MY MODEM IS ON WITH ALL CORRESPONDING LIGHTS ON, BUT IN XP NO DEAL, WHEN IN MAC OS X EVERYTHING IS FINE
PLS ADVISE

Are you using bootcamp or a VM? If you are using Bootcamp did you install the drivers? If you are using VM did you connect the NIC in the VM interface?

IMac not waking up from sleep after 10.6.6 combo update

Prior to update everything working fine, permissions repaired, file structures sound, no issues. After update, iMac won't wake up properly from sleep. Moving mouse (either Bluetooth or wired) has no reaction. Hitting key on keyboard (Apple aluminum extended wired keyboard) causes desktop screen to appear, but the spinning gear/pinwheel appears in screen center, and continues to spin. This continues and continues, no reponse from keyboard/mouse. Only work around has been to force quit computer and reboot. Problem repeats next time computer goes to sleep. Repairing permissions has not effect on issue, but now list of permissions getting repaired is very lengthy. Causes? Solutions?

Macster,
Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job. If you own one, run it first.
After that Repair Permissions.
No need to report Permissions errors....we all get them.
Then, Try downloading the 10.6.6 Combo update, from this site (yours may be corrupt), not Software Update disconnect all firewire + USB devices except keyboard + mouse,Repair Permissions, re-install update, Repair Permissions again + try.

Late 2012 i7 iMac not waking up and also finding wifi enabled after I turned it off as I use ethernet

I have a late 2012 i7 3.4 imac with 32 GB ram. I am finding a perplexing issue and I hope someone may help me out. I am blessed with the inability to wake my mac up after an overnight sleep intermittently must push power off and then turn on again to reboot. I noticed since this started that the imac wifi is always turned on when I restart . i connect via Ethernet (FIOS). The wifi connection is a extension of my FIOS router wifi. Will there be any problems with wifi on along with Ethernet connection? The only software I have on my mac that shows it can work with either connection is CrashPlan.
I have no idea how the wifi enables itself as I do not activate it and the icon in the upper taskbar is an empty triangle usually. This am it was a triangle filled with black lines and when I checked it was enabled. Any suggestions or tips would be greatly appreciated. Thank you.

I've got kind of a radical suggestion, if you want to try it. In cases like you describe a full OS restore, then setting the iPhone up as a new device can fix all these little glitches. It is a lot of trouble, I know, but if you do want to use the service this is one method that should clear it all up for you.
Thank you, it's good to know that Apple does offer refunds. I want it to work, if it does what I would like the $25 would be more than worth it.
I thought clearing my music and starting up iTunes Match with an empty music library might do the equivalent of a full reset... I can't say I really feel like doing that, and I'm skeptical it would clear up all of the issues I've had (play counts, play lists, album art, data usage when I told it to bloody well not use the data).
Thanks for the input!

Imac not starting up properly

When I restart my iMac it starts with a black screen and the word 'root' at the top left corner of the screen. What do I type in so that it takes me to the login page?
If anyone can help, greatly appreciate it...

Yeah it worked before...I forgot the admin password and the only way to change it was to reset it using the installation disk. I cancelled it before it completed and when I restarted the computer the black screen appeared.

How much RAM do you have? Does this happen only when you have a lot of applications running, or completely randomly? How long do you wait before you power cycle?
I ask because I was having the same problem, until I realized that I was being impatient. Sometimes it just takes a while for the login screen to appear after you wake the computer. Probably the computer is swapping a bunch of stuff back into (or out of?) memory as part of the wake up process. Mind you, I don't swear that this has always solved my problem, and therefore cannot promise that this will solve yours.

Windows 7 does not power off properly with bitlocker enabled

Hi
I've got an X200T and installed W7 Enterprise. Things are mostly working fine but i ran into a problem with bitlocker.
When shutting down, the shutdown process but does not power off my laptop battery: bluetooth light stays on, fan stays on, hardrive stay on.
the funny thing is if i force the complete shutdown by pressing the ON/OFF button for several seconds, the next startup run smoothly, the system does not detect any wrong shutdown.
i found a threat relative to this problem elsewhere but nothing on this forum.
i'm wondering if any of yours are able to run W7 enterprise 32bits + X200T + bitlocker without any problem
Let me know
cheers

Hi,
I can not tell you about a correlation between your problem and Bitlocker, but what I can tell is that I also have this issue (from time to time - my system is seldom shut down ^^) on my machine, which is a T400, without using Bitlocker. So maybe this is a BIOS defect, as I don't remember this happening before BIOS version 3.
OSs under which this happened are Vista x64 and Win7 x64.
Greetz!

Lookout V 6.7 causing Windows 7 64 bit not to boot properly?

I have Lookout Version 6.7 on a Panasonic Toughbook CF-53 with a 512GB SSD and 16GB RAM running Windows 7, 64bit OS. I have a 1TB External hard drive connected to the laptop also, though Lookout is not loaded on it.
When Lookout was installed the following would occur: I shut down the laptop at the end of the work day, it shuts down with no issues. I come back to work the next day and power the laptop up, Windows 7 will not start up properly. I get to the "Please Wait" before you have the prompt for 'CTL - ALT - Delete' to login.
I then power off the laptop and restart Windows 7 using Safe Mode with No Networking. If I try to use Windows Safe Mode with Networking, I can get to the login in prompt, then I get past that and get to 'Welcome' blue swirl and then it hangs there.
I removed Lookout and all of the NI software that was loaded and the laptop seems to boot up ok.
The strange thing is, it only seems to affect it when I power up after being powered down. When I do a "Restart" in Windows, the machine will boot up properly. It is only after a Shutdown and power it back on do I have an issue.
I think there is a service that is trying to start that Windows is having an issue with, but I am not sure which one it could be.
Any help would be greatly appreciated.
Thanks!
