Mac Pro :: Screen Sleep For One Second While Using Computer
Dec 7, 2014
Screen sleep one second while i'm using. 5-15 times per a day.
It happened when i worked Mac Pro with External Harddisk WD&adapter transfer from thunderbolt(Mac Pro) to firewire800(External Harddisk WD) or when i just search info in internet.
It could happened all. I just bought Mac Pro and Mac Screen not over 4months.
Today i think this problem cause of my Mac Screen so i sent it to Apple Agent for checking and they give their screen to me for working instead my screen.
But when i open and work with their screen just one hour, i have to shocked because screen sleep one second again. So i think this problem is not about Mac Screen.

Mac Pro, OS X Mavericks (10.9.4)

I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

When waking from "sleep" the screen appears normal but, the pointer leaves a trail of grey as it moves and the whole screen will turn grey if I keep moving the pointer. The computer is effectively dead. Have to shut down by using power off for six seconds and then re-starting. I know little about computers!

I have torrents going all the time. If the computer goes to sleep, the internet disconnects, so they stop. Display sleep wouldn't disconnect though. Is it OK to have computer sleep on "never" but keep display on "15 minutes"? I don't usually even leave the computer on overnight.

For some odd reason, when I try to put my Mac to sleep, it decides to dim the screen and show me that "You need to restart your computer" message in 8 languages. I usually keep my Mac on sleep when I am gone.

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?

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.

My macbook, 3 years of age, always turns on whenever I put it into sleep mode. It gets REALLY annoying. So I close the lid, and a few seconds later, you hear the macbook turn on, then a few seconds later, it goes back to sleep mode. This happens endlessly and it gets really annoying.

I went into system preferences > Desktop & Screen Saver > Screen Saver. And then I changed the "Start Screen Saver" option to never, but it said for the others after 10min " Your computer will sleep before your screen saver activates. So will my computer stop downloading a file from the internet if i just leave my computer on over night? How do i change my signature?

When my computer goes to sleep it will not wake up, and I have to shut down using the power button on the back and then restart. I called support and they advised me that this only happened when the computer went to sleep on it's opwn but not when you manually put it to sleep, But that proved not to be true. It will not wake up under either situation? The support persontold me to logonto applke and re-install the sytem software which I have done but that did not cure the problem either. I have my preference set to never sleep. I am ar]t a loss as to what to do now as when it goes to sleep or I put it to sleep i sometimes will not start up even after shutting down and restarting.I am on 10.7.2?

I've got a dual G5 running Panther and I put it to sleep when I go to work in the morning. Last night, I wanted to try out Tiger (yes, I know - I'm way behind the times) so I installed it on a FireWire drive and booted off it for a couple of hours to see how things worked. I then went back to my internal Panther drive, and everything is ok except for one thing: when I hit "sleep", it goes to sleep, the screens turn off, and then for some reason I immediately hear the internal drives spin back up and the thing turns on again! Why can't it stay asleep?

I'm currently on an internet plan that is divided into on peak and offpeak times. I am coming up to my monthly cap of onpeak and i am either asleep or not home during my offpeak times. I was just wondering if there is an app out there that i can use to easily set my MBP to wake from sleep at like 2 a.m. to start downloads.

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.

I posted something up a little while ago.. Just got this Refurb MBP 15.4" 2.66Ghz 320GB HD 9600 512MB And when my computer dies (0%) it doesn't go into regular sleep, so when I plug it back in I can't just hit the spacebar. I don't like this and want to be able to turn this off?

I had my iMac 27" for two months, and I am very pleased with the machine - except for one thing. When I put it to sleep, the computer just go to sleep in a couple of hours and then return to no-sleep. It started just after I bought the computer. I always set my computer to sleep, and so I did even then - but the first thing I noticed was that the hard drive was started during the first night. Strangely, I thought and put it to sleep again. Then I fell asleep, but when I woke up next morning the computer was on.
Then I wrote on another forum and they told me to check out: Wake up in network access, which I did. And then it got better. Now the computer has been without problems for a month, but then a few days ago it came back. This box is still check, so it can not have anything to do with it this time. I've also tried turning off all programs, the keyboard and mouse when it has gone down to sleep, but it still restarted. What is wrong? Please run with Sleep and it is a program that will prevent the computer to wake from sleep, but not:

What can I do? Can I submit it to Applecare? Some peoples say you do not have to turn off a Mac, but I want to put it to sleep, but it starts up the next day. I've also restarted the SMC, but it gave no effect.

I'm running OS X Lion Server on a Mac Mini 2ghz Core 2 Duo and every time it wakes from sleep I get a message saying "There is already a computer on the network named MacServer, renaming to MacServer (2)".
It only happens when waking from sleep. If I reboot or use the mini for hours without sleeping it's fine, but once it's gone to sleep it renames on wake. When it sleeps overnight it's named MacServer (5) by the morning, as it wakes up every two hours or so to re-register itself on the network and each time it renames itself.
I don't have any other compters on the network with the same name. The only other computer is a MBP and has a completly different name. Here's my setup; My Mac Mini is wired via ethernet to a Time Capsule. AirPort is turned off (I've tried on and off).My Mac Mini has a static IP address (x.x.x.40) with DHCP for everything else (DNS, etc.)The Time Capsule is wired to an ADSL router via ethernet. The ADSL router manages DHCP and NAT, with IP pool x.x.x.2 through x.x.x.30. DHCP and NAT are turned off on the Time Capsule (bridged mode). Wireless is turned off on the ADSL router.Time Capsule is handling wireless.
I've tried resetting the ADSL router. I've tried resetting the Time Capsule (to factory defaults).
The problem seems to be with mDNSResponder, as the log seems to suggest that it is this daemon that thinks there's a duplicate computer name. I've even looked at the source code for mDNSResponder and the last mod-log entry suggests that a fix was put in for this issue in 2009. It doesn't look like it's fixed it, though.
I've tried doing a fresh install of OS Server several times now and, after the last install, it started happening before I got a chance to restore from a Time Machine backup. i.e. on a completly fresh install and assigning a completely new computer name.

Again--my iMac desktop computer (10.8.6) is refusing to go to sleep, as it usually does automatically if left alone for a short time. Even when put to sleep manually, it pops on again by itself. Wasting a lot of electricity!

When I awaken my G5 in the morning (when its chilly) it goes back to sleep almost immediately. This may repeat twice before it finally stays on. I initially thought it was my HD, a new purchase at the time. However, I have switched to another internal drive and have been experiencing identical results. I've run TechTool Pro, Onyx, Applejack, and Disk Utility, thinking it was a HD issue, but having switched drives, I'm thinking it must be a hardware issue of some sort.

My computer sometimes turns off when in screensaver/ sleep mode. Then it doesn't want to turn back on. It eventually does. It's annoying!
