OS X :: Why Does My G-5 Shut Down My Computer In Sleep Mode
Nov 14, 2008
Could someone please explain to me why my computer is shutting down in sleep-mode. In addition, when it happens, the fan goes into hyperblow, which doesn't make sense because it would not be operating if the system were completely shut down. It acts like it is shut down but won't respond or wake up, etc. I re-loaded my system software per the Mac Store Genius' advice, but that didn't work. Is it possible that my power supply is going?
My iMac shut itself down last night while in sleep mode. It's rarely ever turned off. I cannot get it started today. I'm not the most tech saavy person but can follow instructions if someone could walk me through it.
Purchased in 2006 and has worked well until now. AppleCare has expired.
Coming from Windows sometimes I hibernate the laptop but I have heard alot of people say with Mac's that they just put them to sleep. Firstly do you just do this for short periods as such as overnight? Also can your carry them around whilst on sleep or should they be shut down.
When I select Sleep mode - nothing happens. Does not go to sleep.Now suddenly, when I select Shut down - the MacMini does not shut down but obviously working in a loop. I have to do a hard power down.
so i've been having an issue with the double tap to hi-light any text i wish to copy. Such things as double tapping the URL bar to hi-light the whole url so i can just retype w/e site i want to go to. Every time i restart or turn off or my mbp goes to sleep and i reopen it, the double tap function resets. So i'm forced to go to the system preferences > trackpad> "double-click speed" to slowest in order to get my double tap to hi-light anything again. Is there something wrong with my mbp? Or is there a way i can save the settings when i put the double-click speed to slow so that it wont reset every time my mbp needs to be woken up or restarted?
I tried SMC resets and everything. The Macbook takes a charge and charges normally when it is asleep, or off. It will charge to the max (96%). Battery has 349h load cycles. Charges when asleep or off. As soon as I power on the laptop or wake it up, it will stop charging. Battery holds the normal charge I usually get (3ish hours). Tried a few pram and smc zaps. Battery charger is a Hong Kong knockoff. Battery inside is genuine. 2008 Aluminum Macbook. Cleaned magsafe and port with q-tip and still to no avail.
When plugged in, it will run *off the battery* and the charger will show a green light and not trickle charge the battery. It will drain the battery, and then when it is drained it will run off the power. Check the screen shot. I am thinking that the charger is the culprit. Because it holds a charge when I let it charge while it is off. It will charge up just fine, in the two hours or whatever it takes to charge itself up. Battery usage is normal when it is running off the battery.
iMac 27 locking up after sleep mode requiring full power shut down and rebooting in safe mode then shutting down and rebooting normally.. Permissions and this check show no errors, the only error sleep mode failure. Boot up is very slow as well as wake up when possible is slow. Yosemite seems to need a new release in order to correct the boot problems. System operates more like a Windows machine than Apple machine what's going on?
Before and since i had upgraded to Yosemite my macbook pro mid 2012 15" has not gone to sleep when i shut my lid i have tried to reset to default in the power settings but that didn't do anything any thing els i could do?.
I have an APC Back-UPS XS 1500 that I'm using for my Mac Pro. I had some issues with it beeping at me all the time, which has stopped. But now it's causing sleep problems with my computer. When the Data Port is connected to USB, the computer won't sleep. I unplug it and it sleeps just fine.
On occasion, my MBP does not "wake up". My only alternative is to restart, Anyone else have this happen? Is there a way to wake up from sleep mode beside a restart?
my monitor turn's off but the computer never goes into sleep mode. I've got both my monitor and computer set to turn off at 45 mintues of inactivity. I tried reseting the pram with no success. I deleted the com.apple.PowerManagement.plist file. but it still doesn't turn off, only the monitor. I've set it to 1 minute but only the monitor will turn off. Manually putting the computer to sleep work's fine.
When my computer is about to go into sleep mode or when it is being activated from being inside sleep mode or any time my computer goals idle for 10 minutes or so something inside my computer clicks. So far there has been no problems is this a normal sound to here?
If I put my comp on sleep mode, could I put it in my backpack and move around? OR is the hard drive still actively on and it may dmg my cpu/hard drive?
I recently brought my computer to the Apple store to repair dents on the outside of my laptop.Ever since I received it back it does not go into sleep mode when I close the screen.
I'm having a problem with my PowerBook G4 where is goes into sleep mode at random times. Mostly when I am streaming video..or at times the fan comes on, it sounds super high then boom. sleep mode again. After hitting the space bar, it comes back on, but it'll happen again shortly after. I've played with the sleep settings
As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.
The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.
How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.
I just had the original 300 GB hard drive fail in my aluminum 24" inch iMac running the latest update of Leopard. I wasn't able to save it using diskwarrior (diskwarrior said it was some sort of mechanical failure) but I was able to recover most of the data from it by booting from an external hard-drive.
So I went out and purchased a brand new Western Digital Caviar Black 1TB drive. The install went fine, it found the drive partitioned it and installed Leopard successful. Then is crashed and disappeared when I left it alone to run all the software updates. I came back and the computer was stuck on "Restart Required" after downloading all the updates. I went to hit restart now, and the system just hanged, wouldn't do anything. So I hard powered down the system and restarted it. It came up with nothing, just stuck on the White Screen of Death. So I plugged the external drive back in and booted from it. Mac OSX couldn't find the drive and diskwarrior would crash if I tried to run it. I tried to boot up from the OSX start-up disk and it couldn't find the drive either.
So I took the case apart and made sure all the connections were solid and the drive was mounted correctly. Everything looked fine so I plugged it in and it started up fine. Finished the updates and the iMac ran great.
So I thought maybe it was overheating, so I've installed smcfancontrol and started to monitor the temp of the drive. I also took the mac apart again and sucked out any dust in the fans or vents. The drive never goes over a 105 F, so it doesn't seem to be overheating.
However, this is where the problem is consistent: everytime the iMac goes into sleep mode, it crashes and the iMac is unable to find the hard-drive again. Unless I unplug it completely for 5 minutes or so. Once I unplug it, it finds the drive and operates like a champ.
I think maybe there's an issue powering the drive back on? Anyone have any ideas?
And my follow up posting later that day:

So I ran some tests just to see if was an overheat issue, hard drive malfunction, or sleep issue. I decided to start encoding a video, pulled up Word, Power Point, Excel, started downloading all 6000 mail messages off my server (I never delete my e-mail :-/), also started installing iLife 09, and pulled up a bunch of webpages in Firefox with multiple tabs.
However, I shut off all sleep mode options on the hard drive. I let it run for an hour and came back. Everything is fine, hard drive isn't locked up and smcfancontrol shows the hard drive running pretty hot (115 degrees) but not so hot I'm worried. So it's definitely something to do the hard drives going into sleep mode and not powering back on. It's also weird that I have to leave the computer completely unplugged for 10-15 minutes before the drive is recognized again.
So turning off sleep seems to be my work-around, however, this shouldn't be a long term solution. I'm worried that there is a bigger issue with the iMac, but I'm not sure what would cause this. I've been a PC guy for years, this was my first Mac, and honestly I don't know enough about the inner workings to narrow this down. I would assume this would have to do with the motherboard in some way? But I'm not sure how you would even test it.
After using my MacBook Pro I close the laptop and it goes to sleep. Later when I return to it and open it, sometimes it can't find the network. The computer is able to see that I have an Apple Network available, but it won't connect.Sometimes when I try to connect, it gives me a timeout. How I fix it is to walk over to the router and unplug it and plug it back in. After I get the green light again, I go to the Apple Network and it works.
I am currently am using a MacBook Pro mid 2007 and was wondering it is possible to connect it to an external monitor and if so use it when closed without the comp going into sleep mode.
I am getting a pop up "Are you sure you want to shut down your computer now?".
The one we get, if pressed the power button to switch it off?. The problem is not consistent and mostly I get if left inactive for some time(random). I have run the hardware test(installer DVD and pressing D) without any issue found.
I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.
I did a bit of reading on the internet, and it looks like most computers will not boot into 32-bit mode by default with 10.6. It appears that if while booting the user holds the 6 and 4 keys, the computer will boot into 64-bit mode.
Does anyone know anything about this? Will the computer always boot into 64-bit mode if this is done once? Will it even make a difference? Will the average user want to do this?
I'm sure this is do-able as someone's mentioned it; Can you set a MBP so that it doesn't go to sleep when the lid's shut and it's connected to an external display? Got meself a Mini-DP to VGA adapter yesterday but it's off-putting watching streamed TV with the mac open next to it!
