PowerMac G5 Goes To Sleep But Turns On Right After
Jun 4, 2012
I have a PowerMac G5 1.8GHZ dual core with two GB of ram. I have read some posts saying that a cannon scaner, or an HP printer can cause the computer to not go into sleep. I have one HP 5550 printer If I unplug it, and restart the computer, then try to put it to sleep, it works sometimes. It will work sometimes with out the printer disconnected as well. I went through the Firmware on start up and reset all, and that seemed to work for a while. Now it will not go to sleep. It acts like it goes to sleep, the screens turn off, and I hear the click of the Power Supply turning off, but right after that click the computer turns right back on.
my monitor turn's off but the computer never goes into sleep mode. I've got both my monitor and computer set to turn off at 45 mintues of inactivity. I tried reseting the pram with no success. I deleted the com.apple.PowerManagement.plist file. but it still doesn't turn off, only the monitor. I've set it to 1 minute but only the monitor will turn off. Manually putting the computer to sleep work's fine.
MBP/Lion - I'm using my MBP in dual monitor mode with an external monitor and power supply connected. If I close the lid and then disconnect the monitor, my MBP won't wake after opening the lid. I know that with Lion a change was made and the power stays on with an external monitor attached and the lid closed (with the adapter plugged in), but if you unplug the display, there doesn't seem a way out of this state. Even plugging the monitor back in, the display wont refresh In this state the power managment is confused. When closed, the power light is on, with the lid opened the power light goes off, the display remains blank and I can't wake the device. The only solution is to re-boot. as I just want to close the lid, unplug power and the monitor and leave work to go home. I end up running the battery down if I don't catch it before putting the MBP in my bag, and I always have to reboot.
I have a little problem with my last generation 12" Powerbook G4. Sometimes, after I wake it up from sleep mode, the screen has a kind of blue tinge to it, as if there was some blue transparent plastic stuck to it. After I reboot, it's just fine.
I am on a 17" macbook pro using lion and my laptop wont go to sleep. I shut the lid and the screen turns off but I hear it still going and the light in the front doesn't begin to blink like it is suppose to. I have reset the pram and the smc and its still not working
I was using my MacBook this evening and navigated to a webpage that wouldn't load (perhaps due to excessive load) when my screen turned off and refused to turn back on. The white "sleep" light remained constant. I shut the screen and the light started to blink after the optical drive made it's noise and then I opened the screen again. The display turned on for a few seconds turning back off and the light on the front reverted to it's constant state.
I repeated pressing keys, the mouse and closing and opening the screen a few times before holding the power button down and forcing it to shut down. It's working fine now. I am wondering what caused this sudden behaviour though and how to best stop it from happening again, if I was working on something that needed to be saved, I'd be buggered. Perhaps it's an issue Apple needs to service, but how do I reproduce the effect then?
At the time I had a few applications open: Mail Safari Mercury Messenger iTunes (not playing) Last.fm helper app (but no songs were currently playing)
I was thinking it could possibly be related to the Last.fm app, but why would it turn my screen off and then cause it to continue to not respond/turn off? Should I be looking in the Console for a log before shutting down tonight, would that reveal something?
when working on my new Imac sometimes the machine put itself in sleep mode! The screen turns black and I have to enter my password. Sometimes it happens 2 times in 1 minute; other times once in 1 hour.
I am new to this forum, but hoping I can get an answer here. When placing my Macbook Pro in sleep mode by closing the lid, it goes into sleep mode, but immediately turns back on (with the lid closed), then after a short time goes back into sleep mode and then immediately turns back on. It keeps cycling like this. Any clues to why it will not stay in the sleep mode?
I recently had my screen replaced because of a crack. Now I find when I open the laptop to use, after being on sleep mode. It momentarily turns blue, sort of flashes/glitches then works normally. Should I be concerned?
When waking from "sleep" the screen appears normal but, the pointer leaves a trail of grey as it moves and the whole screen will turn grey if I keep moving the pointer. The computer is effectively dead. Have to shut down by using power off for six seconds and then re-starting. I know little about computers!
2.- I tried to turned on pressing the turn on/off button and it did not do anything.
3.- I disconected the computer form the wall and wait for some minutes, and it did no do anything.
4.- After about 20 minutes i tried again and turned on by pessing the on and off button.
5.- The imac turned off again and disconected form the wall and conected to another electrical contact at the wall, adn it did not turned on. i wait for some minutes and turned on again, but after about five minutes it turned off again.
6.- I left the imac connected to the wall for a couple hours and i tried to turned onn by pessing the on/off button and it did not turned on.
7.- I left all night connected form the wall and tried to turn it on this morning and it did not turn on.
8.- This time, I only disconnected the imac cord form the back of the computer and left it for a couple of hours, then I concected and turned on
9.- All the times that the computer turned on it started like a restart and no announce or windows appear telling me about an error or something like that.
10.- One of the times I touched the computer at the back and felt it hot, not too hot, but I do not how normal is.
11.- I can feel some very, very little air at the back form the vent.
What do I hve to do? What kind of tests can I do to know if the computer's an is working ok?
In tiger you could easily disable safe sleep and remove the sleep image file but in Leopard this seems to have changed. Yes you can disable safe sleep & remove sleep image files but only temporarily. As soon as you restart or change energy settings back to default, leopard automatically reverts the safe sleep settings to default and starts creating an image file again
Is there no way to permanently disable/remove these?
I leave my Air on pretty much all the time, and put it to sleep while moving around etc. Sleeping it disconnect the Airport connection - which if very annoying. At a desk I've just been dimming the display all the way off in order to keep my connection.
However, I recently noticed that by setting a "sleep display" hot corner, my network connection is maintained.
I have 2 questions: 1) Is sleep display equivalent (functionally) to simply dimming the display all the way down? 2) Is there a way to either set up a shortcut to sleep the display (other than a hot corner) and/or set it so that only the DISPLAY sleeps after 'x' minutes?
I set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?
I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....
I currently have a G5 powermac (and a macbook pro) and was looking to find out what cables I would need to get them connect to my TV. I have a 27" full HD LG tv which has these connections
- HDMI in - USB in - RGB in (pc) - DVI-D in (pc) - RS 232c in
There is a Powermac G5 available in my area for $450. Its a dual core 2.3 and a nvidia GeForce 6600 and he is including a 20 inch ACD. I don't know if its a great deal, but I think it would be great, because I could build something wild in that case later.
i need a free disc's to install on my g4 as it got 9.something on it i need 10.4 or lower ? i dont really now as i'm new to macs but i got given a macbook pro 10.4.10 install discs they are silver some one said they are surpossed to be black.
I have torrents going all the time. If the computer goes to sleep, the internet disconnects, so they stop. Display sleep wouldn't disconnect though. Is it OK to have computer sleep on "never" but keep display on "15 minutes"? I don't usually even leave the computer on overnight.
I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.
I recently bought a PowerMac G4 1.42GHz Dual Processor. It has 2 gigs of RAM on it. It was a fair deal I think. The "thing" is still looking like new and shiny. Even the insides are still tidy and intact. My question is, would I still be able to pump more juice from this beast. It still run fast comparable to some decent windoze box. Up to how much processor can i be able to squeeze out the CPU and if possible, how to?
I have a G4 Power Mac. It's the "digital audio" model that has been upgraded with a 1.2Ghz G4 processor. It works well except for one thing. It shuts down randomly and suddenly. Then after 5 or 10 minutes it turns itself back on, reboots and runs fine. (It is set to re-boot after a power failure.)I suspect what is happing is the power supply is turnning itself off due to some kind of a thermal, self protection switch. The fan seems to work but the PS gets warm.What's the cure? Replace the power supply? If so where to get a new(er) one?
