Computer goes to sleep while I'm working

Hi everyone,
I was hoping someone can pinpoint my problem and help me fix it.
My computer goes to sleep while I'm working on it.
Just by itself. Sometimes right in a row.
Does anyone know any tips that I can use.
I copied the contents from Console.app
and here is what I found:
sleep demand recorded: Thu Mar 1 08:14:57 2007\n\n
Mar 1 08:49:24 My-G5 EÊæÔ[137]: sleeptime recorded: Thu Mar 1 08:14:57 2007\n\n
Mar 1 08:49:24 My-G5 EÊæÔ[137]: waketime is: Thu Mar 1 08:49:24 2007\n\n
Mar 1 08:51:46 My-G5 EÊæÔ[137]: sleep demand recorded: Thu Mar 1 08:51:46 2007\n\n
G5 Mac OS X (10.4.7)

If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--
(username is your name or System Administrators name)
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
Cheers!

Hi I bought the oxford dictionary app a while ago and it worked fine . Now with the new iOS it starts and closes instantly. I don't want to buy it again. Who can I turn to?

Try closing the app via the device's multitasking bar and see if it works when you re-open the app : double-click the home button to open the taskbar and then swipe or drag the app's 'screen' up and off the top of the screen to close it, and click the home button to close the taskbar.
If that doesn't fix it then try a soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the equivalent of a reboot.
If the app still doesn't work then try deleting the app from your device and redownload it (assuming that it's still in the store) via the Purchased tab in the App Store app - or resync it from your computer's iTunes (if you don't have a copy of the app in the Apps part of your computer's iTunes library then copy it over via File > Devices > Transfer Purchases before deleting it).
If that also doesn't get it to work then contact the developer.

I have lost AirPlay and sharing with my PC since accepting a software upgrade to the TV yesterday. I have tried restoring and reinstalling this software but this failed to solve the problem. Any suggestions would be very welcome.

I have lost AirPlay (with iPad and iPod touch (new) both on os5 ) and sharing with my PC (uptodate iTunes) since accepting a software upgrade to the Apple TV yesterday.

Check your Windows settings along this contribution from Chrism0:

Also check that the ports 5353 and 5354 (Bonjour (mDNSResponder), AirPlay, Home Sharing, Printer Discovery) are open on Windows Firewall.

IMac going to sleep while I'm working on it

I will be working on my Imac, final Cut or Imovie or just simply surfing the internet and the screen will go blank. I move the mouse or a key and the computer comes back the way it was why is it going to sleep on its own?

You are describing the screen going dark while you are working. And you say that moving the mouse brings it back. That sounds like display sleep. Just moving the mouse wouldn't wake up the computer if it had entered sleep. You would need to click it or press a key.
>I have the engery Saver set to 15 min.
Which one is set to 15 min? There are two "sleep" functions, computer sleep and display sleep. Fifteen minutes is much too short for computer sleep and much too long for display sleep.

Had problem downloading Elements 13 so used the live chat - advisor downloaded a trial version, even though I've paid for full version. I now have to enter the serial number every time I want to use PE 13. Any suggestions? Many thanks

In using it, I found out other's have had this issue and it likely means you have a 3G iPad? If you do, go into settings and turn off cellular data, then try to update again and you should be OK........

MacBook Pro goes to sleep, doesnt wake up!

I recently bought a new MacBook Pro, and have noticed that this problem started since I downloaded a widget: Deep Sleep, which basically allows the Mac to go onto a Hibernate mode. I have uninstalled it now but the problem still persists, so I am not sure if that was the cause. My Mac goes to sleep but does not wake up, the Apple logo on the loading page comes up but thats as far as it goes. It loads almost upto the end but then stops. I have to press and hold onto the power button for it to restart. Any ideas why this is happening and what I can do to solve this issue?

HT1338 My macbook pro goes to sleep randomly and only wakes up when i tilt it

I bought my new macbook pro last june in miami and somehow it just goes to sleep on its own in the middle of doing anything.
Clicking, pressing the start button, the space bar or anything won't wake it up. Tilting it or lifting the computer would. And that's scaring me. It just did it 4 times in a row and i am just browsing the web
Anyone know if this is a hardware thing or the software is going nuts or my mac is haunted ??
I have the mac insurance thingy so should i call them or what do i do? Thanks for the help

Check your current setup (I left my MBP as "3")
go to Utilities > Terminal
After you launch Terminal, the first step is to determine which sleep mode your Mac is currently using. You can both view and change the sleep mode using the Unix program pmset. To see your current settings, type (or, copy and paste)
pmset -g | grep hibernatemode
press 'enter'
You should see something like this:
$ pmset -g | grep hibernatemode
hibernatemode 3
Great, so your machine is using mode 3, whatever that might be. Well, thanks to the documentation for the handy Deep Sleep Dashboard widget, which puts your machine immediately into hibernation mode (so you don’t have to yank all the power sources to invoke it), we can tell exactly which mode is which:
* 0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
* 1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
* 3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
also, I enabled this:
go to Utilities > Terminal
type in sudo pmset lidwake 0 then "enter"
it will ask for your password. type it in, that's it!
Now, when your computer is sleeping with the lid closed, when you open the lid nothing happens until you press any key ... nice: keeps it off when accidentally opened, like in a backpack?
WARNING: Improper use of the sudo command could lead to data loss
or the deletion of important system files. Please double-check your
typing when using sudo. Type "man sudo" for more information.
To proceed, enter your password, or type Ctrl-C to abort.
There are several other lengthy threads on this forum dealing with this issue ...

Why does my macbook pro "goes to sleep" when charging?

Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
I read from threads that it is a logic board problem....How do I solve this problem?

Try an SMC reset. Follow the method for "a battery you should not remove yourself."

Why does my Macbook keep going to sleep every 10-20 secs!

why does my Macbook keep going to sleep every 10-20 secs when first turning on then it seems ok after about 10 mins ? This has only happened since upgrding to Lion 3 days ago, it's driving me mad!

You are most welcome

My macbook pro goes to sleep by it does not wake up. I have to restart it. I had recently to change the board in the attached Thunderbolt display.

my macbook pro goes to sleep by it does not wake up afterwards. I have to restart it. I had recently to change the board in the attached Thunderbolt display, because I noticed that the same problem arose when the display was attached.
Now with the new board, it can't be the display's fault. I hope it is not macbook pro's main board fault. Maybe hasthe notebook board been damaged by the faulty display?
To bring my MacBook Pro to service will slow down my work. This is why I am posting this message, in the hope to be able to run a diagnostic test myself.
Thanks a lot, in advance.

Hello Aminetti,
It sounds like your computer goes to sleep, and will not wake up, so you must manually restart your computer. I recommend the troubleshooting in the following article:
OS X: When your Mac doesn't sleep or wake
http://support.apple.com/kb/TS5357
Reset SMC
Reset NVRAM/PRAM
Test with external devices disconnected
Try Safe Mode
Try another user account
Thank you for using Apple Support Communities.
All the best,
Sterling
