Power Mac G5 :: Fan Runs On High And Won't Wake From Sleep - It Freezes?
Dec 10, 2007
I have a G5 (Power PC, g5, Dual 1.8 GHZ with 1.25 GB SDRAM, and Mac OS X 10.4.10-phew!) and I recently: added more USB ports using a PCI card, and purchased a non-Apple 22" widescreen display.
Prior to adding USB ports, I was using a hub that ran off its own power source, and used a Samsung 19" monitor.
My situation now: everything starts up fine, but ultimately the fan will kick in at SUPER HIGH and won't stop. I can put my Mac to sleep--which stops the fan noise--but then it won't wake up.
I have run the Apple Hardware test and everything checks out OK. I've also reset the SMU according to directions from this forum; AND I've vacuumed out all the dust bunnies.
The fan runs so loud and so high it sounds like it's an airplane that's about to take off.
Short of bringing in my Mac to a technician, can you recommend anything? My Mac has been glitch free up until now.
I purchased my PowerMac G5 in 2003 and no problems till now. My problem is that on startup, the display first shows gray screen with a globe in a white box flashing in the center of the screen. This continues for about 90 seconds --- then the globe in box icon changes to a small file folder icon with alternating face/question mark flashing in the file folder. At about the same time, the fan speeds up dramatically. The fan continues to run at this high speed for about 90 additional seconds, then the fan returns to normal speed, and the startup continues normally to the blue screen. Once startup is complete, computer runs okay. The whole process takes about 4 minutes.
Information: PowerMac G5, 1.8 Ghz, OS X 10.2.8 Mac OS X (10.2.x)
I have a MacPro 2.66 quad-core intel. 4gb ram. I have a hard-drive from my old Powermac that i upgraded to 10.5.5 for this computer. Everytime I put my computer to sleep, and then wake it back up. The fans spin up to maximum speed and all the fans are running really loud and then after about a minute all spin to normal speed.
I don't have any other flaws except for this. Why could this be?
Since the 10.5.8 update my Macbook wont wake from sleep (black screen) and i have restart it with the power button. The Macbook is totally frozen: the keyboard doesnt respond (caps button light wont go on and etc.) and my external monitor wont come on either.What I've tried:
-Install combo update 10.5.8 (i did normal update first time) -Started up with all the magic keys combos (PRAM and SCM or whatever) -Tried the fix where you need to (re)enable the ethernet port -Set sleephibernate mode to 0 - Repaired permissions and disk aid etc.
Every hour or so, my computer freezes up and then restarts itself. Once restarted, it does an error report and tells me that "Sleep Wake" has experienced a problem. Is this a hardware problem? What I should do about it?
I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.Unfortunately my cats like to touch the keyboard, thus waking up my Mac.Is it possible to wake the mac only by pressing the power button?
I've been fighting bad sleep crashes for over a year. Sometimes it would freeze when it started sleep, sometimes when trying to wake from a sleep. I've spent countless hours researching the problem, reading everything on the boards. I tried resetting the PMU, turning off Bluetooth, removing all USB, and all of the other suggestions. Nothing alleviated the problem. Last week I replaced the lithium battery on the mother board because it wasn't keeping the correct time. So far it is sleeping and waking perfectly for the first time in ages. No more freezes or jet engine fans. I have my fingers crossed. Power Mac G5 dual 2 GHz, purchased June, 2003
Sometime when I stop using my MBP for a minute or so, the screen goes black and won't wake up. I can see that the lights are on the keyboard and it's running but won't wake up. I will have to hold the power button down and then restart. Does any one know how to fix this? It's starting to do it more and more ofter.
I just bought a new dual 2.0 ghz power mac G5 about 2 weeks ago. I set everything up and dowloaded all the updates for everything, and then about a week into using it the problem started. I left for work and when I got home that evening after the computer had been asleep all day, it sounded like the computer was taking off from a runway. It would not respond at all to the keyboard or mouse so I had to shut it down by holding the power button on the front of the unit and then start it back up. I called tech support but they had me turn the option off that puts the harddrive to sleep when possible and then turn off my screensaver. Well it was fine again for about a week and then it happened agin yesterday, not once but twice. I looked on apple discussion boards and there is alot of this happening. Well I took one guy's advice that seemed to know what he was talking about. I restarted holding the command-option-o-f keys down, then prompted the computer to reset the v-ram, and two other things he suggested to reset that I cannot remember. Then I restarted, trashed the energy saver prefs and ran a repair disk permissions task inside OSX. Well that is where I am now, and it has not done it again, but I am still trying to find out what exactly is going on here. I just spent $2000 on a machine and it appears messed up and Mac has no answer.
So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3.
The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.
I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests.
At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower).
MacBook Pro 2.16 Intel Core2Duo with 2 GB 667MHz SDRAM runs very quietly when being used. When left with lid closed overnight but still logged in, each AM the the fan is running loudly at high speed and the case is hot. As soon as I open it and it starts up, the fan quiets down and the case is cool in a few minutes. The temps range (when open and quiet) from 90-125 F for various components and the fan speeds are about 2000 RPM. Why should it run hot when closed and asleep.
Macbook Air won't shut down and often the fan runs at a very high rate without stopping. I do notice it seems to get hot on the bottom more than in the past. Any suggestions as to what I should do, I can't keep holding the power button down to shut off the computer.
I'm using iStat and it says that my CPU runs at temps around high 70s, low 80 degrees Celsius for about 10-15 minutes at a time (also says the same for Airport card). It usually takes a while for it to cool down. I always place my laptop on flat surfaces. It does this even during light internet surfing minus flash or any other multimedia...now WITH multimedia use, it reaches the 80s no problem and I just quit the process cuz I don't want my laptop to explode one day.
I just wanted to know if this was average and what temps everyone else is usually running at?
I'm afraid that if it runs at these high of temps for a long time each time like that, then it may do some damage somewhere...
Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off.
I purchased a used ibook from owc in January and have had it back to them twice for repairs. Lately, it stopped booting up again and they told me to use [URL] to take the mobo out and ship it to Arizona to have the solder refloated. I did and got it back, put it together and it would boot up, only to run for 15 minutes and shut down. Thinking I missed something, I dissasembled it today and reassembled it. Now it turns on with a blank screen, the fan runs on high, and it will go no further. I tried to reset the power manager, reset the p-ram, the hard drive is only a few months old and my brain is getting fried with frustration.
It all of a sudden started opperating very very slowly, even when doing simple things like clicking the apple icon in the corner, it will freeze or take foreve to open. Its constantly showing the spinning rainbow cursor and it literally takes 20 minutes to turn on. It would take hours to send an email.
My laptop has been having problems track pad doesn't always work, runs slow, freezes. I replaced the hard drive on advice and that didn't help. I went to disk utility and verify and repaired disk permissions, that didn't help. I went to the erase tab and I clicked on "erase free space" thinking that would "defragment" free space, like a PC has.Now all my available memory is gone.I thought I was freeing up space. Now my apps don't work correctly and I can't reinstall because I don't have enough disk space.
So my Macbook Pro has been working wonderfully, until recently when it runs out of battery it goes into sleep mode but when I plug in the power cord it does not do the restoring from how it was before (i don't know what its called, but its when the screen goes grey and the white bars go across until i can get back in) it does not show me anything so I have to press the power button and even then it does not show me that screen it just reboots (i don't hold it in but just press it normally like when booting it up) Then when it is booted the date and time are reset and the Wi-fi does not work. I have to reset the clock and it then works fine.
I've usually in all my year with Mac not had my drives sleep. I note now that when my drives awake one of the fans is spinning faster than normal. Just a little nothing crazy and then it slows to normal.
Is this the sound of a problem fan or something on my motherboard or something?
Should I do a PRAM reset? or whatever it's called these days? Running OSX 1.6.8

Pages (5.2.2, which has "An error has occurred" note in the purchases section of my App Store application)
Keynote (6.2.2)
Numbers (also has "An error has occurred" note in the "Purchases section" of my App Store application, and while it shows "installed" in same section, Numbers does not appear on the recently updated list in the "Updates" section)
and iMovie (10.0.5)
I also recall an Adobe update occurring (Macromedia?).
I began experiencing slow wake-from-sleep behavior. More recently, I have been getting "out of application memory" dialogs upon waking from sleep. There have also been a couple instances where the computer would not wake and had to be restarted. At one point, without having gotten the "out of application memory" dialog, I did note that virtual memory had ballooned to over 14 GB. That stayed like that until I logged out and logged back in.
This behavior seems to be specific to a user account (did not repeat when logged in as admin for one overnight test, but haven't tried an all day admin login).
I've tried uninstalling and reinstalling BOINC, as well as removing an Adobe Resource Synchronizer app from the user login items (given the recent Adobe update, and having read that said item could cause trouble).
So, I'm not sure how to proceed beyond offering the reports below:

Issues with my G5 DP 2GHZ. My rig has been fine since day one, but since I changed my system drive, and added a second drive, the fan radomly goes into a crazy high speed mode, and then locks up, requiring a hard shut down.
Heres the facts: *my os is 10.4.9 *2.5 gb ram *used carbon cloner to copy my original system disc to new Seagate 7200.11 1 TB drive *installed second 1TB storage drive. *both drives divided into 6 partitions. *both drives formatted OS extended [Journaled] *jumpers are in the correct position *drive firmware is SD15, the correct, and most current *drives are set to never go to sleep *fan/freeze is not task specific, meaning it will lock up with no apps open *this fan/freeze is sporadic, and has happened three times in the last 4 days.
Ive attached the system log. I know nothing about these logs, so my apologies if Ive included too much, or not enough data.
Whenever my battery gets drained, my MacBook Pro turns off as if the battery was pulled out, I lose all my work when this happens.This started after I installed Snow Leopard, before, it would just go to sleep and my work is safe.
Anyway, sometimes I'll leave my MacBook Air on without the power adaptor attached, and the battery will drain.That's all fine and dandy.The problem is, is that instead of going to sleep LIKE IT SHOULD, it will completely turn off, and everything I had up (web pages, anything and everything) will be GONE when it starts back up.

I have this Power Mac G5 and every now and then it'll freeze up, the fans will go full blast, and the screen will go black. It's not even when I put a heavy load on it.I usually just hold the power button down and do a hard shut down. Does anyone know why this G5 keeps doing this? Should I re-seat the ram and GPU?
My macbook pro won't charge again or even start up if it runs out of battery power, so I use my wife's power cable it charges and starts .. I have to charge it with her's for 20 min, then I can use mine and it works fine ..
I have an intel based mac pro running tiger. When it falls asleep if it's asleep for an extended period of time...say 45 minutes or longer, it won't wake up. I have to manually power it down. If it's asleep for less than 45 minutes it wakes up fine.
I have a MacPro Dual 3GHz, running OS 10.5.8 and when my Mac goes to sleep, it won't wake up. Fans speed up and light blinks, but I have to do a hard reboot.
