Turning off sleep mode during high CPU usage

There isn't option to prevent going to sleep mode during high CPU or network usage. This is not professional for serious work like 3D rendering, video montage, downloading or sending large files. Windows is going to sleep during performing serious tasks.
Setting different sleep mode values every time is no way because we didn't know how long these tasks will running.

Is it better to leave your macbook pro in sleep mode during the night or have it shutdown all night?

Is it better to leave your macbook pro in sleep mode during the night or have it shutdown all night?

During sleep, your MacBook consumes a little part of the battery, so it won't harm leaving it in sleep mode. Also, you will be able to start using it quickly, as you don't need to wait until Mac OS X turns on.
I only recommend you to turn off the MacBook if you are not going to use it for days in order to save battery, but apart from that, you don't need to turn it off

IMac Enters Sleep mode during video playback

My imac started behaving badly a few weeks ago. It seems that at times of video play back, itunes, youtube, vlc, that my iMac just says nope and goes to sleep. I have tried resetting the ram during start up and it took care of the issue for all of an hour. I am at my wits end here please somebody give me a solution.

The times that your machine goes to sleep are times when you are maxing out the RAM. However, try looking in your Console>system log for any references to exceeding the maximum temperature for more than 30 seconds; that would indicate a thermal problem, probably the power supply unit failing.

Will a 3 hour long download of an upgrade be cancelled if the Mac goes to sleep mode during the download process?

I have a Mac 10.10.1
27 in. monitor
2009 late
Memory 4GB 1067 MHz DDR3
To download the above OS upgrade (10.1.1), because I noticed the long time needed to download, I clicked on system preferences, Energy saver, Computer sleep/never,
Display sleep/15 minutes.
The download came through in flying colors.
My question is, did I need to do that, or could I have left the Energy Saver alone and the file would have downloaded anyway?

Does ColdFusion 11 go into sleep mode after a period of non-use?

I've just installed CF11 on my cloud server (running Windows Server 2008 R2) for a shopping cart app using SQL Express Edition in the backend. After periods of inactivity, especially every morning, when I go into my app, it clocks for about a minute then errors out. Eventually, after another try, I'm able to run my app but it's sluggish for another couple clicks then it's back to normal.
I've been running this app on an older version of CF for almost a decade (I just upgraded to CF11 last month) and this problem never happened during that time. Can you provide any guidance on how I can fix this problem?

Unfortunately, you really only answered the first question: Rackspace. I would double check with them to make sure your virtual server itself isn't going into a sleep mode during off-hours.
For question 2, you will need to log into CF Administrator and note the Application and Session timeout settings, and let us know. Also, you need to examine your Application.cfm or Application.cfc and see if server-wide timeouts are being overridden (look for ApplicationTimeout and SessionTimeout).
For question 3: you said in your initial post "After periods of inactivity, especially every morning". This implies there are periods where NO users are using the app, and is quite likely when your timeouts are occurring. If the application times out in ColdFusion, the application is stopped and the first request after it is stopped will restart it. Depending on what you have in your Application.cfm/.cfc, this could either be a very quick process or a very lengthy one.
Another possibility is the database. Depending on the level of activity and if you have any scheduled database tasks running (like database maintenance/index rebuilding or SSIS packages running), the database itself could be the issue. SQL Server Express is throttled to only use one CPU core, 1 GB of memory, and has a size limit on databases (the limit varies depending on which release of SQL Server you are using).

G4 Sleep mode Issues

Hello all,
I have a G4 Dual 1.25 running OS X.2.4. The problem is it goes into sleep mode every 10 seconds or so. Then I have to wait a minute for it to fall into (what I call deep sleep) "rem sleep" then I can awaken it with a key stroke or moving the mouse. But at best I have 10 seconds before it shuts down again into sleep mode. It even goes into sleep mode during SHUT DOWN!
I have reset the PRAM button on the board to no effect. As of last week it was running just fine. Friday it began doing this and I can find no reason for it. I have checked the sys pref and made sure the power save settings are at "never" sleep. It does no good.
I can be working (what I failed to mention is when I first boot up I may have 5 - 10 minutes before the first sleep mode) and the screen will go black.
Any help is greatly appreciated.

Hey BrianW.
I can't say I know what's going on with your Mac, but I was having a problem where leaving my Mac idle would cause it to "freeze."
If I had the screensaver enabled, it would not go away after moving the mouse or anything, like it was doing up until about a month ago.
I tried disabling the screensaver, but still the "freezing" happened.
Sometimes I would be successful in getting out of this "frozen" state, but the hard drive would first sound like it was slowly dying.
I had read somewhere once, and although it didn't apply to me then, I thought of it when my problems started happening.
I downloaded this:
http://www.versiontracker.com/dyn/moreinfo/macosx/20791
It's freeware called Jiggler, and it jiggles your cursor based on how you set the parameters.
Here is a screenshot taken with Grab so you can see the options (there's no screenshot on the link I'm giving you):
[IMG]http://img301.imageshack.us/img301/5317/jigglerdh1.png[/IMG]
As, you can see, I set Jiggler to jiggle at intervals of 40 seconds when the computer is idle.
This has successfully solved my problem temporarily, until I go to the Apple Store to find out the cause of this.
I have not had any freezing since, so I have nothing but good things to say about this app.
Hope everything goes well, let us know what happens.

Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
          Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading
          Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
3. Reset the PRAM.
4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
7. Repair permissions on the startup volume.
8. Turn off Bluetooth and test.
9. Reset the System Management Controller.
10. This step shouldn't be necessary, but has been advised by Apple Support in some cases, apparently as a workaround for a bug. Open the Energy Saver pane in System Preferences. If applicable, click the padlock icon in the lower left corner to unlock the settings. Enter your administrator login password when prompted.
Select the Power Adapter tab and uncheck the boxes marked
          Wake for Wi-Fi network access
and
          Enable Power Nap...
if present. Then, if the computer is a MacBook, select the Battery tab and uncheck
          Enable Power Nap...
11. Reinstall OS X.

Does a mac perform self diagnostics during sleep mode?

does a mac perform self diagnostics during sleep mode? I was told it does about 10 years ago.

.. but it you leave it on at night, the OS will run the Unix CRON maintrenance routines.. during 3:15 and 5:30am (not in Sleep mode), the cron tasks will be run.
http://support.apple.com/kb/HT2319
Russa, from the KB article you linked notice that those maintenance scripts are no longer invoked by cron. They are invoked by launchd:
Additional Information
The tasks are scheduled for 03:15 to 05:30 in your computer's local time zone. This is described further in "Mac OS X: Unexplained Disk Activity Produced by 'find' Process." These tasks do not run if the computer is shut down or in sleep mode. If the tasks do not run, it is possible that certain log files (such as system.log) may become very large in Mac OS X v10.5 or earlier.
Therefore no user intervention is required, unless you are running Mac OS X "Leopard" or earlier.
It may seem overly pedantic to bring this up but this common misconception has a tendency to lead people into believing a Mac requires the user to perform maintenance over and beyond what OS X already accomplishes by default.
As others have written, a Mac takes care of its own housekeeping. It is best to simply let it work as designed.

Encore WT8 - battery discharging during the sleeping mode

My battery is discharging during the sleeping mode.
If I sleep the tablet with battery fully charged then battery is fully discharged after 14h.
I suppose that must be something wrong with it. I cant find any option to activate functionality to switch off (hibernate) tablet when it is not used in sleeping mode for particular time.
Do you have any solution or advice what I should do to change energy consumption during the sleeping mode?

Hi
The system supports connected stand by function which starts working after your tablet goes into sleep mode.
Connected standby function is to provide a constant connectivity while delivering long battery life and at the same time some activities are allowed to run to ensure that the supported connected standby scenarios (for example receiving emails, updating tiles alive with fresh content, downloading/uploading a file from a/to a website and playing music) are functioning properly.
What does this mean?
This means that even if the tablet is set into Sleep Mode, some background processes are still running and this could be the reason why the battery discharges.

Charging iPod nano on an Intel iMac during Sleep Mode by Firewire

Hi everybody,
I have a question concerning the iPod nano. I know that you can not sync the iPod by Firewire but you can charge it. I also know that charging the nano via USB during Sleep mode is NOT possible. However I had a 3G IPod (connected by Firewire) and it was possible to charge it when the Imac was in Sleep mode. And here comes my question:
There is a special cable for iPods, which has both Firewire AND USB. Is it possible to connect the IPod simultaneously by Firewire and USB to the Imac with the result, that the nano will charge during sleep mode (Firewire) AND is able the sync music (USB) ???
Thank you

Hi lora,
Don't do it! See this post:
Using the iPod Dock Connector to FireWire and USB 2.0 Cable
Which states this: "Important: Never connect both the FireWire and the USB 2.0 connector to your computer at the same time. Doing so can cause unexpected behavior."
Good luck,
maz

Severe battery loss during sleep mode

I have a brand new MBAir and I'm trully intrigued about the loss of batery happening during sleep mode. I've fully charged it on Friday, and, since then it's been on sleep mode. Today, finally turnign it on this night to work a bit, I found it has only 73% of charge! What can be happening? IMPORTANT: My "power nap" mode is OFF since I've bought it and started using and noticing this down charge. Can anyone help me?

I've just solved it all when I noticed I kept plugged in my wireless mouse receptor. Just plug it out before leaving the MBA in sleep mode, and the problem was solved.

IMac 2009 (21 inch) making hard drive noises during sleep mode - normal??

Hi there guys,
I have an iMac 21 inch (2009) , 3ghz C2D, 4GB Ram, 1TB hard drive (the hard drive was upgraded straight thru apple, when i bought it i paid extra for a 1tb hard drive, its not a DIY hard drive upgrade)
aniways, I recently noticed that during sleep mode, occasionally (not all the time) I can hear some faint clicking / hard drive noise, which is really weird because i put the imac in sleep mode and it really shouldnt be doing that no?
My 13 inch macbook pro 2010 never does this in sleep mode, its always dead silent
Im just wondering if this hard drive accessing / clicking noise during sleep mode is normal in imacs??

Im just wondering if this hard drive accessing / clicking noise during sleep mode is normal in imacs?
No it should not be doing anything but sleeping. The SMC controls sleep, try resetting it.
Reset the SMC
• Shut down the computer.
• Detach the computer's power cord.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Reattach the computers power cable.
• Turn on the computer.

What is causing my Mac to crash during the sleep mode?

Hello!
I would to have your help on this situation that i am having for a month or so... Ok... it started about a month ago, I turned it on and all of the sudden, it shut down, then rebooted on its own... (actually it rebooted like 3 or 4 times before running the system) I thought that it was odd. I had my Tech to look over and see what was causing to crash and all... he could not find anything then we all decided to leave it running all time... so we did. a week or two later, it just crashed when i woke the sleep mode and it went on the usual route as crashed and rebooted two or three times before going back to normal.
sound familiar to you guys? after that happened, we turned off the sleep mode and so far, it is doing good... decided not to update the system's Security software because it may have something to cause the mac to crash down...
the mac is 2 x 3 GHz Quad-Core Intel Xeon, 8 Gb 667 MHZ DDR2 FB-DIMM, running on 10.6.8
appreciate your help on this.

One more thing.... it makes weird sounds as well... very high pitch sounds that you hear in movies where UFO flying by while it is doing the rebooting...
