My Mac falls asleep automatically!!

I need help fast diagnosing my Mac Problem!
Out of nowhere yesterday my machine started to automatically shut down and go into sleep mode without me touching anything or making any settings changes. The screen goes blank. The hard drive winds down but comes back to life once I click my mouse. This is now happening every few seconds and I cannot even run diagnostics before it shuts down.
It's a PowerMac G4 (Quicksilver with 5 hole front). About a month ago I upgraded to OSX Tiger 4.7 and was running fine with no problems.
I check energy saver and made sure it was set to 'never' for the sleep selection. I disabled my hot corners but it still keeps doing it.
I even unplugged the system and vaccumed out the dust from the fan grates thinking it was overheating and powering down as to protect from overload but still no go.
I don't know if this is software or hardware related issue or if I picked up a virus. I've never seen or heard of this problem before and can't find any info on it.
If anybody has any information or suggestions please respond here or email me at [email protected]

It is incredibly rude to threadjack other users' topics. You posted this same verbage in three other topics in the Power Mac G5 forum, and to top it off, your problem isn't even related to a G5!
What you should do is create your own topic (as you've done here, albeit in the wrong forum) so that any responses will be grouped, and you and others won't have to search through several different topics to see what others have written.

Mac falls asleep while ordering Photobook

I use an iMac G4 with the latest OS and iPhoto.
When ordering photobooks, I experience my mac falling asleep (i.e. 'lighthouse mode'). My internet connection is wireless, and I know the Mac sometimes looses the connection with my airport; but finds it back my itself. iPhoto can handle this; it just stalls sending, and continues automatically.
The mac itself however falls asleep after 1h no activitiy; but iPhoto running and having network activity doesn't mean 'now activity'.
I can overcome the problem by switching of sleeping in energysaving options; but it's anoying.
I also experience it sometimes with programs like Realplayer.
Does anyone know how mac defines 'activity'; and how I can overcome this issue?

Martijn567:
Welcome to the Apple Discussions. I don't know how Apple defines "activity" but I know that you have to turn of the sleep option when you're encoding and/or burning iDVD projects to disk image or directly to disk. So it seems to be a system wide issue for operations that rely primarily only on CPU work. It's just the nature of the beast.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.

After my mac falls asleep, i have to put in my password in querty altough I work in Azerty.

Hi,
I use an Azerty keyboard, as I am from Belgium.
When my Mac falls asleep it, I have to put in my password in Querty.
Once log in it reverts back to Azerty.
Is this a bug, or is there a solution to this.

Mac falls asleep when battery gets down to roughly, half charged

it falls asleep once it gets to this point, and then i wake it up and the charge has gone right down.
Does it need to be calibrated? or is the problem bigger than that?

Most likely you need a replacement. There are known issues with MBP batteries, and an extension of the battery warranty to 2 years, as described on this page:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
Go to System Profiler (Apple menu > About this mac > More info) and click on Power. If the Full Charge Capacity is less than 4400 mAh for a 15" or less than 5000 mAh for a 17" MBP, your battery is failing. If your Cycle Count is less than 300, your battery is failing prematurely and Apple will replace it for free. If that's the case, call Apple or visit an Apple Store for a free replacement.

Try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption as Archeeum so helpfully suggested (if it stays running long enough!). The link will show you how.

I like to watch tvcatchup or sky go or I player on my iPad while falling asleep, the problem is that the iPad then stays on all night. I would like to find an app that allows me to set a timer for the iPad to switch itself off automatically.

I like to watch tvcatchup or sky go or I player on my iPad while falling asleep, the problem is that the iPad then stays on all night. I would like to find an app that allows me to set a timer for the iPad to switch itself off automatically, like the sleeper function on a TV.
Does such an app exist? Can anyone help me? Thanks

You can try the Sleep Timer.

Mac keeps falling asleep for no reason

So, I have a MacBook pro w/ retina display. It falls asleep when I am using it. All the time. And then makes me re log in. I don't want to shut off sleep mode, as I like it. But it won't stop.
Known issue? Fix? Thank you in advance.

We have no way of see your Mac so you are going to have to tell us
exactly what model of MacBook Pro you have
disk space
amount of RAM
what operating system are you running
any error message you might be seeing

Why does my phone automatically hang up if i fall asleep on the phone?

Everynight Im On The Phone With My Boyfriend And We Both Fall Asleep, But When We Wake Up The Phone Has Hung Up But Neither One Of Us Hung Up... Why Is That?

I don't know the particulars but it's not hard to image that when the connection detects no traffic for a certain period of time it automatically disconnects.

How do I stop my external HD from falling asleep??? So, so Frustrating!!!!

Hey Apple users
OK, I have a Seagate 500GB external HD formated with MAC OS Extended. This puppy is great, very dependable, only ONE issue...
After not using it for a few minutes, it falls asleep, and when it needs to be used, it takes an annoying 6 seconds to start up. Working with audio and having live samples that are stored on this HD, not having them playback for a few minutes (ext. HD then falls asleep), then playing back the entire project with these files needing immediate use, the software CRASHES because it can't access the data fast.
I have no room on my PowerBook HD for much at all. This also causes problems in iTunes, wanting to play a song after not touching iTunes for a few minutes (when not playing), iTunes freezes for some seconds until it can access the songs on the external HD.
SO SO ANNOYING, the internal HD takes like .01 seconds to access data. And this HD takes like a painful 6 seconds Ugh,
How can I keep my external HD awake ALL THE TIME, unless my entire Mac is asleep??
Thanks!

Actually, this app. I mentioned above... HDriveAwake... is not a good idea,
it has many flaws, but it's decent software, just needs some improvements, main issue: consumes an incredible amount of RAM and Processing PWR while working.... (on my mac.. consumed 60+ %) & this is a bad thing if you use an EXTERNAL HD for stuff like audio/photo/video editing... I'm just going to get a Mac Pro G5 with like 4TB, I need it.... my bank account doesn't, but i do...

My iMac G5 randomly falls asleep during use.

A few weeks ago I was using my iMac and suddenly lost control of the cursor, cursor became invisible and computer went to "sleep" (ie; screen went black, "woke up" a few seconds later after moving the mouse). This problem has persisted in all sorts of conditions and uses. Usually the intial episode is followed by another shortly after. The problem happens a lot while streaming video on the internet. However, the computer also falls asleep when using photoshop.
The problem began when the hardrive was nearly full (15 GB left on drive). I cleared out many of the larger files (lossless music files) to gain 87 GB or so. Problem persists. I mostly use this computer for typical web stuff (email, facebook, videos on youtube and the like) and graphic design (Illustrator and Photoshop). Hard drive had never been defragged. I usually restart the computer when problem gets really bad.
I've searched various forums for a solution. Many argue about defragging, some mention OS reinstall, no real clear consensus seems to exist about why the problem occurs or what to do about it. Any ideas?
Specs: Mac OS X, 10.4.11, 2.1 GHz G5, 1 GB DDR2 SDRAM

Your problem sounds more like a heat problem. Try resetting the SMU:
   1. Shut down the computer.
   2. Unplug the computer's power cord.
   3. Press and hold the power button for 5 seconds.
   4. Release the power button.
   5. Attach the computers power cable.
   6. Press the power button to turn on the computer.
If that doesn't clear things up defragging won't do anything much, the best would be to try an
Archive and Install http://support.apple.com/kb/HT1710
which will give you s shiny new OS, but keep your prefs and settings. Make sure you select that option when reinstalling.

How to set my Mac to wake automatically when invited to join a video chat?

Is it possible to set my Mac to wake automatically from Sleep when invited to join a video chat?
Also, is it possible to show that I am still available when my Mac is sleeping?
It seems that if these settings are not possible, there can be no spontaneity with iChat. You have to pre-arrange a video chat by email or whatever, in which case you are not adding much once you have arranged the call--you may as well carry on with the email or whatever other contact method you use.
Or is there some other way to arrange video chat?

No, neither of these are possible. When your Mac is asleep it does not remain connected to anything on the 'net.

The only way you could do it is to leave your Mac on and iChat connected at all times. You could then set your display to switch off after a certain amount of time.
That way your Mac will remain connected via iChat and you'll be able to receive video chats at any time. In fact i believe an incoming call via iChat will even switch the display back on (though i haven't tested this myself).

Dual G5 falling asleep again ramdomly, need help!!! DUAL G5 2.0gHz

I can't get any work done. I updated to the latest greatest OS that software update told me to do and now every time I try to work on anything processor intensive the computer fall asleep and I need to hit the escape key to wake it up. This will sometimes happen 2-3 times in one minute. I've posted on this problem several times in the last year and usually I've been able to get the machine running again. However this time nothing is fixing it. I've downloaded the combo update, trasted the ,plist files, reset the PRAM and cleaqned my cache, repaired permissions, booted from 10.4 install disc, run diagnostics, checked log files for thermal runnaway (never seen that one). Unfortunately this computer is about 3 years old now and all warantees and apple care have expired. It's had issues since the get go. I've had to replace the logic boar, case and one of the processors. I'm about to pay the 50 bucks and call apple but I was hoping that there would be a solution here first. Please help. My business is suffering...
Joel

Try this again also. 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.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.8 Combo update. Others reading, download the combo update that applies to you!
Cheers!

Macbook keeps falling asleep

Every time i turn on my mac, it keeps falling asleep. I press a button and it wakes up, and then for a second or two its up then falls asleep again.

Same problem with a teacher's computer I work with. Tried the SMC reset and it didn't work. Tried PRAM reset and it didn't work. So I took the power adapter out (the battery was fully charged), and it started working fine without the adapter. I used the computer for a few minutes and put the adapter back in. The fan might have gotten faster, but I am not sure if that was normal now. Anyway, it is working for the time being, but tomorrow is another day.
Because I work with a lot of Macs, I have seen the sensor replaced a couple of times because of this. [Crossing fingers.]

IMovie 11 Exporting Movie and No File and External Drive Falling Asleep

Help! Had a frustrating day and night with iMovie, which has been happening a lot lately.
We are making a highlight video for my son from his many sports events which are on a 3TB fixed external drive and a 2TB portable one. After putting the highlight video together with clips from both drives it is time to Export the movie which I am doing to the 3TB Drive. However after completion, there is no file anywhere. Upon taking the same steps with same filename, there is no warning about existing file. I have tried to export to local drive on Mac as well.
Also, if I do a higher quality export it takes a while and the external portable drive falls asleep. Any way to keep it awake without sitting there and accessing the drive manually. I looked in the drive settings through the mac and it does not tell it to put the drive to sleep. In hindsight we should have had all videos on the 3TB drive but I am afraid to move them now.
And...we put some arrows in pointing to him with a freeze frame and PIP. The arrows are there when I select them manually but don't appear when running through the movie as we preview the entire footage.
HELP!!!! Thanks
