ML goes to sleep during a download

Why is ML going to sleep thus there is network activity ?
With Lion there where no issue.
Tried it on several Mac's with same result.

Since installing Mountain Lion, I can be sending video to my TiVo, uploading to the internet, downloading from the internet, repairing permissions or even burning a disc and my Mac might decide it is idle and just go to sleep. I like that it goes to sleep when it really is idle but not when I am doing something. I found an application called Caffeine that I can run to keep it from going to sleep, but I shouldn't have to always remember to do that. The most recent problem I had was after accidentally erasing a hard drive, I did a deep scan using Disk Drill then started to restore items to another drive and my Mac went to sleep during the Restore.

MBP 2010 goes to sleep during login

I cannot boot up by MBP. It starts with the gray screen and the apple. The baton spins around a while, then the display goes to black, not suddenly, but a quick fade. Sometimes it then comes up again with the gray screen and the cursor in the corner. But then it goes back to black.
The computer is unresponsive - caps lock does not respond. Looks like it is asleep - white light is pulsing, battery meter shows full, charger is charging.
I have hard shut the computer many times. Occasionally, it will show a flash of a screen before shutting, and the screen is the waking from hibernation, like when you wake the computer after the battery is low and the computer shuts down by itself. But it is fleeting and the battery meter shows fully charged.
I have a feeling therefore that it is going to sleep during the login process.
I have tried PRAM and SRC reset - no change.
I have tried to boot in safe mode, and it also goes to the black screen.

Hey Frederic
The next step is to boot to your install disk or Recovery Disk and use Disk Utility to verify the Disk. After that the next step would be to reinstall the operating system.

Prevent monitor going to sleep during slideshow

Prevent monitor going to sleep during long slideshows. It's very annoyng having to 'shake' your mouse every few minutes to prevent screen blackout.
Some programs do that (e.g. BSPlayer when playing movies).

Hello DeniWilco,
Since you can isolate when the issue happened the first thing to consider is doing a system restore to a time before the issue happened.
Can you reproduce this same issue while in safe mode?

How do i keep my ipad from going to sleep during presentations

I'm using Evernote for notes during a presentation. How do I keep the iPad from going to sleep so I can read my notes?

Bey you have have an MS Exchange account on the iPad (through your work) and they are limiting the options you have (disabling 1, 3, 4 & Never).
Try this...
Settings > Mail, Contacts, Calendars.
Select the Exchange account then set it Off.
Go to Settings > General > Auto-Lock and you should see all options.
Set it to what you want.
Then turn on the Exchange account.
The Auto-Lock settings should stay.
However, if you go back and view the Auto-Lock settings, it will change back toonly 2 and 5.

The screen goes into sleep during use

i just bought mac aie 13 inchs for 1 month, and it constantly blacked out and goes to sleep mode. I need to press the keyboard to wake it. how can i solve this problem?

This problem seems to be affecting many people, and not just on the MacBook air.
There's another thread with many people reporting the same problem here: (unfortunately, with no solution yet, though!)

My laptop goes to sleep during the Time Capsule backup process and never finished. What can I do?

I have an older MacBook laptop that I want to backup on my new 2TB Time Capsule. I have set everything up just fine (apparently) and the backup process starts out fine. About an hour or so into the backup process, my laptop goes to sleep. The laptop is plugged into AC power so it is not a battery loss. I have set 'hot corners' so that my screen saver is disabled. Nothing seems to keep the laptop running until the Time Machine process completes. Any guidance appreciated. Thanks!

You don't indicate what operating system the MacBook is using, but in general try the following:
Open System Preferences (gear icon on the dock)
Open Energy Saver
Adjust Computer Sleep to read Never
Adjust Screen Saver to read Never
Run the backup
When the backup is done, change the Energy Saver settings back to normal

HT1553 how do you keep imac from going to sleep during disk utility backup ?

using the install DVD I am attempting to create a disk image backup with the Disk Utility app. However the imac goes to slepp every 10 minutes. eventually causing an error.
I found the commands to use on the commandline in terminal, However I can not use terminal and Disk Utility app at the same time from the install DVD.
I am using moutian lion install usb drive.
The Snow Leopard install DVD could not handle the 3 TB enternal harddive where the backup will be placed, before I do a clean install of Mountain Lion.

this seems to be an issue in (mountain lion?) disk util - actually the second bug that I know of now.
I am having the same issue whilst using zeroDIsk - however the system going to standy seems to slow the task down, it hasn't failed yet.
From what I can see caffeinate will solve the issue (in mountain lion)

New FREE App To Stop External Disks Going To Sleep During Editing.

Digital Heaven have provided this free application to stop external HDs sleeping whilst editing.
I have not had that problem since selecting "Never Sleep" in the Energy Saver panel, but apparently some disks can ignore that command ...... but not with DISKSOMNIA !
http://www.digital-heaven.co.uk/freeware/request.php

Hi Jack,
I think these presets are set in the lacie drive/firmware.
If you have a cd that came with the drives see if it has an app on it that allows you to change the settings inside the lacie.
Hope this helps.

Why does ipad go to sleep during download, why does ipad go to sleep during download

MY IPAD WENT IS SLEEP DURING APP DOWNLOAD, THEN TURN ITSELF OFF WHY?

They all do. It saves battery power. Always attach to the charger when downloading. The downloads don't stop, however.

How can I stop my Macbook from going to sleep whilst I load the operating system (10.5) on?

I'm trying very unsuccessfully to reinstall the system from scratch, so that I have a clean computer. I'm starting with 10.5 and then going to upgrade in increments from that to the last operating system the computer will run, which is 10.6.8.
Firstly I've wiped the hard disk in Disk Tools and then started it up from the master disk of 10.5, and its telling me it will take 64 hours and some minutes to install, so I can't keep moving the mouse to stop it going to sleep for that long.
I know it sounds as though something is wrong, but I have run both Disk Tools and Tech Tool Pro through it and both say there's nothing wrong with either the computer or the hard disk, and it was running fine (if slow - but that's its age!) prior to this clean install.
This computer is the first of the intel Macbooks and is a single core intel processor with 1gb of Ram.
What I need to do is to stop it going to sleep during the install, as every time it does it just halts the install and over night, for instance, I'm no further forward than I was the night before, even though I left it going all night.
All I'm trying to do is get it to 10.6.8 so that I can run Bootcamp on it and turn it into a PC to do my accounts (and no, the software we use only runs on PC, but Paralles, VMWare Fusion etc still make it painfully slow to use, and It's bad enough having to do accounts without having to wait for it to do every move...)
I can't go straight to 10.6 as the only copies we have of this are "drag and drop" upgrades that Apple supplied with 3 of our other Macs. Also the computer won't read dual layer DVDs (too old) so I can't load the full copy we have made of the OS.

It's simply called Photos and there is no options/setting thing on it. I have windows 8, it's a stand alone photo library viewer.

Will migration still occur if my mac goes to sleep

I am migrating from my pc to my new mac air but want to know if this migration will still happen if my computers go to sleep mode. Also it is takig a very long time. Is tis normal?

Avoid letting your source computer go to sleep while you are attempting to migrate.
To prevent your source computer from going to sleep during the migration.
Go to System Preferences on the source computer.
Click Energy Saver then select Custom in Optimization.
Adjust the slider for "Put the computer asleep when it is inactive for..." to Never.

My imac g5 goes to sleep while in use. typically when im playing games

For the last several months, my mac has been going to sleep during use. Typically when im playing games, like second life, or in any type of programs, but it has also been going to sleep while im watching videos on youtube or hulu. It's getting worse and worse, and once it goes to sleep the first time, it doesnt stay on long afterwards. When browsing the internet, its fine. I've recently backed up 40,000 images that I had on my computer, and deleted for more memory space. but it didnt stop it from going into sleep mode, it just doesnt go as quickly as it was before. I was told that it was a memory problem, but since i deleted all of the images off of my computer, the problem still persists. I even turned sleep mode to "never". Here are some of my computer stats:
Memory: 512 MB
Processor: 2.1 GHz PowerPC G5
Space Free: 104.18 GB
Space utilized: 128.58 GB
My monitor stays warm, never gets hot, but sometimes i can hear the fan blowing loudly when it goes into sleep mode
If anyone could help, i would greatly appreciate it =)

The temps are a bit higher than I'd expect under normal circumstances, and too high while playing games, but what is the room temp where it is?
I def. think its a temp thing now. but why does it only raise when im playing games or watching videos online?
Games tipically press the CPU, Video Card, RAM, and everything else much harder than most apps.
It may be a Fan not working properly, or just dust buildup.
Boot off your Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.

Ipad2 goes back to home screen during pdf download, and aborts download

Ipad2 goes back to homescreen during pdf download. Have done shut downs, cleared active screens, etc. Still occurs about 1 minute in to a download

When was the last time you powered your iPhone off and on?
Try a reset instead which is similar to a computer restart. Press and hold the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.

I'm using a late 2006 2.33GHz imac.I clean installed 10.6 from disc then updated to 10.7 from download.Now every time my computer goes into sleep it won't wake up.Anyone know how to cure this problem please??

I'm using a late 2006 2.33GHz imac.

Now every time my computer goes into sleep it won't wake up.
The only way it will restart is to pull the mains lead out of the imac, put it back and try until it will start.
This only happened after reinstalling. Only Apple OS was on the imac and so it must be an issue with the software I believe.....
Anyone know how to cure this problem please?
Thanks
paul

This isn't a fix, more a workaround I used when I had wake from sleep problems that lasted from some point in 10.6.x, through 10.7 and into 10.8 (got fixed for me in 10.8.2). It seems to be connected with Bluetooth failing to wake up properly:
System Preferences>Energy Saver and set 'computer sleep' to 'never'.
