My computer keeps going to sleep

My step mum's computer won't turn on. I'll press the on button and after a few seconds a white box with the words "Monitor going to sleep" come up. I've tried taking out the power chord and unplugging the computer, I've also tried to get on the menu in the little time the computer is on for. But it doesn't respond to anything I do.

Computer keeps going to sleep even though it is set up not to

I recently helped a friend set up his iMac to stream to his home stereo system so things like Pandora could be played throughout the house. The problem we are having is his computer keeps going to sleep and back to the log-in screen. In energy saver, we set the computer and display to never go to sleep. We also un-checked the box that says "put the hard disks to sleep when possible." Even after doing this, the display still goes dark and when the mouse is moved to turn the screen on it is back at the log in screen. This causes pandora to stop playback, which is not good since this is why we set up the streaming in the first place. Why is the computer still going to sleep when we are telling it to never do so?

HI Ty,
Couldn't hurt to check the hard disk.
Follow these instructions to verify the hard disk for errors:
Open Disk Utility, in the Utilities folder in the Applications folder.
Select your disk, and click First Aid.
Click Verify Disk.
If the disk needs repairs, do one of the following:
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the menu bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click Repair Disk. When Disk Utility is finished, from the Menu Bar select Utilities/Startup Disk. Select MacintoshHD 10.5 in the window and click: Restart
If you don’t have a Mac OS X Install disc, restart your computer while holding down the Shift key. As your computer starts up, it performs a disk check similar to the one Disk Utility performs.

Computer keeps going to sleep while using compressor

I have been using compressor for years to compress my video files. I edit the videos during the day and I let Compressor run all night long. Last night when I tried to run compressor over night something happened and I am hoping someone out there can help me out. What happened is that after a few minutes (probably 30 or less) my computer went to sleep. I have the computer settings set to never sleep, and it never does. Except now I find that when I run compressor, for some reason it goes to sleep. I can wake it up using the mouse, but that is not productive for overnight batch jobs. I even tried installing "jiggler" a program designed to move your mouse for you, but that didnt work. The computer still falls asleep. Does anyone know what is going on or how I might fix this problem?
I am using final cut Pro 5.0.4 and Compressor 2.0.1
I have a G5 (dual 2.7 Ghz Power PC G5) with 2GB DDR SDRAM
I am running OSX 10.4.11
I have 10 500GB firewire drives
Thank you in advance for any solution options you may come up with.

I got this issue resolved. It turns out that the computer was overheating while using the processor intense compressor program. All I had to do was to open it up and clean the dust out and off of the heat sinks. Who knew that such a simple solution would stump so many people.

After 10.9.6 update, laptop keeps going to sleep

After doing the 10.9.6 updates last night, my computer keeps going to sleep, even right in the middle of typing, the screen goes black and the lights on the keyboard go off. I have to hit a key on the keyboard or tap the touchpad to wake it back up, and re-enter my password. I am also running os x server installed on this laptop and did that update, along with xcode 6
Here are my logs from the console:

OneNote prevents my computer from going to sleep when I have a shared notebook open. Suggestions?

Hello,
The issue is that my computer will not go to sleep if I have OneNote opened with my shared notebook loaded.
Background: I'm currently running Windows 8 Pro on a desktop machine with Office 2010 Home and Student installed. I log into the OS under my outlook.com internet account. OneNote, which I always keep open, has my main
notebook shared on my SkyDrive.
Scenarios: The computer will go to sleep if I reboot the machine and do not open OneNote. The computer will go to sleep if I close my shared notebook, reboot the machine and open OneNote (with no notebooks open). The computer will go to sleep if I open
OneNote with my shared notebook, close it, AND exit OneNote from the icon in the system tray.
The scenarios I ran lead me to believe that OneNote is continuously polling my shared online notebook, thus preventing my computer from going to sleep. The is a regression from the behavior in Windows 7. Are there any configuration changes I can make to
fix this?
Thanks.

Try modify the settings under:
Control Panel --> Power Options --> Multimedia settings --> When sharing media to Allow the computer to sleep

Monitor keeps going to sleep

Hello there
I have a HP Pavilion Elite HPE-063uk Desktop PC, product number: VG251AA, serial number {Content Removed}, with Windows 7, my monitor keeps going to sleep and a message saying VGA NO SIGNAL comes up. The only way to awake it is by switching the pc off at the power button (the F2 or "half moon" button should awake it but does not) .
I have checked everything from the "Save Power settings (which is on off)" to Screen Saver (off as well) and done anything what I can find on the HP help and support, troubleshooting problems, testing this and that, even connected a different monitor and restored it to an earlier date, but I cannot solve the problem.
Please can you help. Thank you.
This question was solved.

Hi vitolaterza,
Are you getting the no VGA signal after the computer goes to sleep? If so this is normal.
Turn off all sleep mode options; make sure everything is set to never sleep.
Check the cables on the back, you only need one video cable going to the monitor. Also go to hp.com and download the latest BIOS and Graphics driver.
Here is a link to download the drivers.
Let me know if this helps.

HP pavillion Elite HPE-541F ... system will not start and monitor keeps going into sleep mode

Good Morning:
Having an issue with my Hp Pavilion Elite HPE-541F and Monitor HP2311x
Yesterday, thinking I was updating Java ... clicked on it and agreed to things being allowed on computer ... started adding icons to my desktop .... then pop ups kept coming up to register etc ... I assumed that something was wrong so I attempted to restore system to previous ... since then my system will not boot up ... will say "starting windows" and I can hear the fans working but thats it ... second part of the issue is that the monitor keeps going to sleep, so even if I try to restart the computer in "safe" mode or anything else monitor goes to sleep and there's nothing on the screen so don't know if anything is doing anything .... Very sorry I'm also not very tech savy with computers ... just trying to save time and money before I have to bring system to computer repair person .... Any help would be appreciated .... Thanks so very much

Since last update XP keeps "going to sleep" when unsed for 10 min.

If I walk away for 10 minutes the computer screen says "going to sleep" The Tower shows green light next to on/off switch but orange light is off. Press start, orange light fires up and I must wait for the whole restart process again. Where do I set the time-out to stay on?

My computer is going to sleep and wont wake up by touching keyboard or mouse. I have to use the power button

Can anybody help? My computer is going to sleep and I cant wake it(bit like a teenager) by using the mouse or keyboard. I have to use the power button. Any ideas?

Hmm, that support link doesn't like me.
Do you have the discs that came with the computer? If so, put Install Disc 1 into the combo drive and boot up while holding the C key. Does anything show up on the screen? Do you hear the fan running? When running from a CD or DVD, the fan usually runs at a fairly fast pace and should make some noise.
Keep in mind that you have a 1-year hardware warranty with any new or refurbished Mac, so if something has gone wrong, you should be able to have it replaced free of charge, unless the MacBook shows some form of damage.

Dual 2.7 Ghz PowerPC G5 Keeps going to sleep

My Dual 2.7 PowerMac G5 keeps going to sleep - particularly when working in power hungry programmes such as Aperture. In fact it is such a problem now that I really can't use Aperture since the machine goes to sleep every minute or so. (I can always wake it up by pushing the space bar.)
I've looked in Console and this is what it tells me:

PowerMac G5 2.7 Dual Mac OS X (10.4.9)

Hi The Hatter! Thanks so much for taking the time to answer my query. Unfortunately I've tried all your suggestions (apart from reinstalling 10.4.9) and nothing has worked.
Reset the PMU; zap pram/nvram from cold start; or,
from Open Firmware.
I zapped the PRAM but to no avail.
Never let drives sleep?
Yes this was set on 'Never let drives sleep' anyway.
Did you add any drives? Seagate?
I have a factory-added drive; the computer arrived from Apple with 2 400 Gb Hitachi HDS724040KLSA80 hard drives
any PCI cards?
None
Does it happen in SAFE MODE?
Yes it does.
Have you got any background tasks 3rd party to
monitor the system?
There's NetBarrier Monitor and VirusBarrier Monitor
What do you see when you boot in Verbose mode also?
What am I looking for here? The screen fills with all sorts of things but I have no idea what they mean!
Did you "use" your Mac when you updated to 10.4.9?
did you use the combo updater? might even want to
rerun that - after doing the old routine of "backup,
repair, run Disk Warrior" first. And run the update
in Safe Mode just to reduce background programs.
The problem was occurring in 10.4.8 as well - and may have even been happening before that, but has become worse in 10.4.9

This is usually a sign that your iPod's headphones are not plugged in all the way. Make sure that you cannot see any of the silver still showing from the headphone's plug. You should hear a sort of popping/clicking noise when inserting the headphones letting you know that they have been fully seated.

Good advice from Linc Davis that should sort out your query i think...
However you dont want to set your MBP to never go to sleep...
Adjust reasonable sleep settings...
And the download an APP called caffiene...
When you click it you can have your MBP never go to sleep with a single click of your menu bar... and with another click it can go to sleep normally to maintain the laptop...
Simply click the cup... To toggle never sleep/sleep
