I've a MDD G4 dual 1.0 along with the wide acrylic-bezel 20" Mac monitor with the light in the lower right corner. Yep, it's starting to look ancient. But I still have much use for it EXCEPT that it has a very nasty habit of turning itself off catastropically in mid-thought, as it were. Oddly, this behavior comes and goes in spurts. it will hit hard for a couple of weeks then a couple of months will pass with relative peace and stability. Then, back to the crisis.
Sometimes I get a warning from that power-on light in the bezel -- it might flash brighter for an instant, then within a few seconds the whole system loses power just as if I'd turned off my power strip. Other times, it pops in and out of sleep mode for several cycles, but usually this ends the same, with no power at all. Odder still, the machine has a tendency to turn itself on unaided. This can happen even after a controlled shutdown. It turns on, acts normal for 20 minutes, then maybe goes to sleep and wakes up a couple of times, then crashes. No intervention at all on my part at any time. This is not a software shutdown of any controlled variety. Anyone know what's happening? I can't tell you how much gnashing my teeth have endured.
My Mac pro will turn on. When the progress bar is finished filling in the mac turns off.

1.- The imac turned off by it self.
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?

Have Word 2004. Don't laugh; it's been working. When got new MBP, Office worked. (Well, can't recall if PPT ever worked with it.)Excel and Word definitely did work. Two weeks ago, Excel started working sporadically, then not at all.Right now(!!), Word suddenly stopped working. "Word quit unexpectedly" and "Excel quit unexpectedly."

I have so far had a few instances of this phenomenon w/ my 15 mo. old Mac. First, when charging my Mac at night in off-mode, it will occasionally turn itself on at some point evidenced by the power-on when it's opened. Then,I have had one instance of a shut-down by itself during use. It restarted w/ no problem. Next, the computer turned itself on with the cover closed and the computer had been off all night. I heard it start up, so I am sure. I do have AppleCare if I need to take it in.

No warning at all, it just turns off as if I've pulled the battery out. I plug it into the mains and turn it back on and it says I have at least 30% battery left. Is my battery dying?
View 4 Replies View RelatedA couple of weeks ago, out of the blue, my Ibook 12" started turning off by itself.
At first it would turn on again, I was able to check the HD with the Disk Utility, which reported a fault in the HD. Then after a few times it wouldn't turn on anymore. I couldn't hear the chimes sound and the fan (or HD) would start running pretty fast.
My airport/wireless works fine most of the time, but sometimes when I close the lid, and reopen it, my airport will not turn back on. It turns on neither automatically nor through the preference pane. The button to turn airport on is clickable, but nothing happens.
I'm new to Macs, and I like them so far. But this is getting really annoying as the only way I've found to fix it is to restart the computer.
I recently bought a new Kensington Slimtype keyboard for my PowerMac G4 (dual 867mhz); it's running Leopard and everything other than this is working beautifully. For some reason, whenever it goes to sleep, it turns the brightness down to it's lowest setting - not a huge problem, I just turn it back up. Just wondering if anyone else is having this problem and if they are, how did they rectify it?

View 8 Replies View RelatedThis baffles me in terms of GB's. I imported a legal DVD to burn off Mactheripper in GB that was 2.7. turning it into a VT file. I then used cinimitize 2.0 making them 3 files, 2 .mov files and 1 audio files. Turns out each segment at 40KB's, 30 segments in all. Then I import the .Mov files to Final Cut Express and when I convert the whole 2hr and 40 min movie out to a "quicktime file". After that I open up the new Final Cut Quicktime .Mov turns out to be 38GB's. I am turning it into hopefully a 30 min film, but I do not understand the math at all, and I simply dont get how a 2.4GB DVD turns into a 38GB Quicktime movie.
View 1 Replies View RelatedI have had my MacBook Pro since May 2007. It has been working fine up until a few months ago. I will have nearly full, or fully battery and the computer will turn off, and will not turn back on unless I plug the charger in. If the charger is unplugged for 5 minutes, the computer completely shuts down. So basically I cannot use the computer unless it is plugged in. It is starting to become a pain because sometimes I need it when I am in a place without an outlet.
View 10 Replies View RelatedI have just recently noticed that when I put my computer to sleep the Apple logo flashes every few seconds and that it gets out of sleep mode by itself. When I went to turn it off it quickly turned on again. It happens whether it is connected or not. I have tried a few things and this [URL] but nothing has worked. I bought this computer last December, so it's still under warranty. I cant reset the SMC because the computer does not remain turned off, when I shut it down it automatically turns on again. Also I did a hardware test, both the short and the long ones and it said that there where no problems. I am a college student and I can't afford another computer so I am a bit scared that this is going to damage it.

I have a late 2006 Macbook pro, it has problems turning on. If its cool it will turn on just fine. If its warm, you have to wait 15 minutes for the MBP to cool down. Is this a logic board issue? It seems so.

I got home to find my mac was unresponsive. I thought it had fallen to sleep so i kept pressing keys on the keyboard and clicking the mouse. Nothing happened, I tried everything. So I turned it off by holding down the power button and turned it back on. But then 10 mins later while using it, the screen just instantly turned off! The iMac was still running, it even had the music still playing in the background from iTunes, but again it was unresponsive to my commands. After 1 minute the music turned into an awful static cry for help. So i turned it off. Here i am again on the Mac after turning it back on, but i'm scared it could just go again any second.

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.

The volume on my macbook pro will randomly turn itself on. The volume image shows up and it then turns all the way up and keeps clicking until I hit one of the volume buttons. But it will do it again about 30 seconds later and it keeps repeating this process for days. Shutting off the computer doesn't do anything. It does this randomly, it may not happen for months but then when it does happen it can go on for days if not weeks.
View 1 Replies View RelatedI have a 13-inch, Mid-2010 MacBook Pro running OS X Mavericks. I was using it near a bathtub, when a moderate amount of water spilled onto the keyboard. I immediately dabbed out most of it, and put it upside down for some time. It was running then, with all the keys and trackpad working fine. t turned it off, and tired turning it on after half an hour. Nothing. I decided to keep it switched off for 7 days, during which I would open the lid every now and then to find vapor on the screen from the keyboard which I would wipe and close again.
I turned it on when there was no vapor spotted for 3 days. I plugged it in after 7 days, to see that the battery status indicator was erratic. It turned on with a sound from the SuperDrive (the usual click). There was no startup chime. A few minutes later, it turned off. I decided to reset the PRAM and SMC, and I realized that I can get to my account window successfully (and type a 22 letter password) as long as I keep any key pressed throughout bootup (option, command key, etc). I have tried many times, but it just turns off with a "nik" sound. I haven't backed up, and I have about 270 GB of important data stored that I CANNOT lose.
It's 250GB drive crashed in December but it was replaced with a 500 GB and has been running smooth until this.
I found a PowerBook G4 in my closet, so I turned it on and was using it just fine, and then without warning it turned itself off. When I boot it up I can hear an internal fan running, and it keeps running the entire time the computer is turned on. I'm not sure which OS it's running. Do I need to replace the fan, or is it something worse?

When in system preferences if i choose use monitor it appears with great resolution, beautiful image. But if i choose "use identical image for both monitors" the resolution on the LG turns crap.
What should i do to have identical image (so i can have my macbookpro with lid closed) but have at the same time an awesome resolution?
I have my MacBook hooked up to a pair of external speakers (M-Audio AV40, for those interested) and I can hear a slight click when the computer hasn't played any sounds for a certain amount time (about 30s to a minute). My PowerBook G4 never did this, so it's not the speakers.
View 2 Replies View RelatedAt least, it seemingly randomly turns off. I can be surfing the web or whatever like normal, but then after a period of time the monitor goes black. I can see that the computer hasn't shut off, but it's as though the computer is on its lowest brightness setting. It can be temporarily fixed some times if I lower the brightness all the way via F1, then put it back up, but if it goes up more than 3 or 4 boxes it goes black again.
It also goes black if I were to move the monitor any time during this whole thing. I've heard things like an inverter cable and board, but I have no idea what's going to fix this. This is my only computer, I use it for all my school work, if it breaks permanently I'm screwed.
Thought it would be fun to troubleshoot it, since I already own one and have taken it apart.
Here's what's wrong with it.
I've gotten it to boot up. Curiously, it describes itself as a powerbook!?
I have a 3 months old MBP SR and recently I have noticed that the charge light on the magsafe adapter turns off after a while. It used to stay green when the laptop was charged but now it turns off. It usually happens when I put the computer to sleep. After a while the charger light turns off. Not a huge issue but I was wondering if other people were seeing something similar and if there was something I could do to get the light back on (I think it looks nice).
View 24 Replies View RelatedI've been digging around for a couple weeks now for information on what may be happening to my MBP. I've tried numerous solutions, but don't seem to be able to get the computer to STAY ON. Here's my story:
A couple weeks ago, my room mate was using the computer. She closed it to put it to sleep, and left it on my bed. When I went to turn it on, the screen was completely black and the indicator light on the open button was a steady grey. The computer was so hot it was painful to the touch. I unplugged it, hard powered it off, and let it sit, thinking it was an overheating issue.
Since then, the damn thing won't stay on. Initially, it would intermittently just shut off. When that happened, sometimes I could boot it back up, and other times it would sound like something was whirring in the background, but the screen stayed black and the indicator light stayed solid grey. I installed SMCFan and istat to monitor/control the temp and fans.
I noticed somewhere along the way that there seemed to be some connection between episodes of shutting down and the power cord (as in, if it was jostled, the computer shut off)(I should note that my battery is at about 15% health with a full charge). Then, that power cord died (no green/amber indicator light and no connection detected). So I bought a new cable, and set about trying to fix the problem again.
Next phase, it seemed that if I moved the computer, it shut down. So I did some of the recommended fixes. I deleted the power management plist, I changed the settings to never put the computer or the display to sleep, and I turned off the quick-motion sensor that stops the hard drive. I also reset the SMC settings.
This seemed to improve the situation a little bit, insofar as now instead of getting a shut down, I am now getting complete reboots that only *sometimes* lead to the blank screen and steady grey indicator light. This does happen more frequently if I move the computer, but it can also happen if I simply leave it to run. In fact, if I send the computer into sleep-mode, and close the lid, I'm practically guaranteed a reboot.
So, then I reset the PRAM and did the hard-reboot (ctrl+opt+power) and reset the PRAM again. I am currently running Rember to test the RAM, but I'm not sure what to look out for when it finishes, or what I should do about it.
