ANybody ever take the case off and blow air over the inside to clear out dust?
My G5 tower is one of the early models. Today I turned it on. Immediately the drive bay fan was running at maximum speed. The Mac's temperature was cold as it had not been used for 12 hours. So the speeding fan could not have been due to the drive bay being overheated. The fan never slows down. Even after a restart it immediately spins at its maximum. Plus it stays at maximum speed all the time.

The headphone plugs don't stay seated in the jack, resulting in loss of audio in either one ear or both until I adjust the plug, at which point it will almost always happen again. I usually end up having to hold the plug in place to get consistent sound from both ears.
At first, I thought it was just my headphones, so I borrowed a couple pairs from friends and ordered a backup pair from Amazon, all with the same results. I've peeked inside the jack once or twice and everything looks fine...but what do I know? I'll be in downtown Chicago tomorrow and Thursday, so I plan on making a trip to the Apple Store, but is there anything else I should try beforehand? As I recall, the PB headphone jack is part of the logic board, correct?
I've decided to reinstall OS X on my powerbook, but I'm having trouble. I can't partition or erase using disk utility from the cd. It says it's trying but it just sits there. When I try to do a erase and install, it stays at "preparing the disk".

This weekend I went to turn off my iBook & it wouldn't turn off. It's now permanently on, with opening info barely visible (like I need to click on F2 to brighten up, except nothing happens).
Currently using my "back up" computer, my iMac Grape, which is pretty much an antique by now.
My screen has become extremely floppy and it is pretty difficult to get it to stay up; if it does manage to do so it is at a pretty good slope. it's old and I have been tough on it, but was wondering how I would go about fixing this to the best of my ability? or. is this the kind of thing I have to take in for repairs?
View 2 Replies View RelatedMy G5 iMac developed problems after upgrading latest updates to Tiger, iTunes, QuickTime, ect.
I am now unable to access apps like system preferences, iPhoto, Safari and others. Also it will sleep but unable to shut down. I'm hopeful a new install of my OS 10.4 disk will correct things but fearful my photos, music and FireFox bookmarks may be lost.
My beloved G5 has been flawless till now.
I recently acquired a 15" TiBook from someone who no longer wanted it. He took good care of it and with the exception of a few slight surface scratches, it looks practically new.
That being said...it won't turn on!!
My question is -- does the battery need to be good for the unit to turn on, even if you've got it plugged into A/C power? The amber light on the plug comes on as if it's charging, and it never goes off. When I hit the little indicator button on the battery, nothing lights up. It would seem quite obviously that the battery is bad, but would that stop the unit from running off of wall power?
If it's just a bad battery I'll gladly buy a new one, just wanted to check before I waste my money!
I'm trying to record something through the internal mic (and I'm too cheap to go out and buy a proper mic) and I was wondering if there is anyway through Terminal,or an external program, to force the fans to shut off for a certain period of time? I don't want to turn them off to find they can't turn back on and suddenly the computer is 1000�...I just want to keep them off to have a minimal amount of background noise. (And, yes, I'll be running it in a moderate climate so the computer doesn't overheat).

I've upgraded my HD two days ago. Today my PB suddenly turned off and won't turn back on. All the connectors are in the right places and nothing looks wrong inside. I have no idea what's happened.

He has no idea what model it is, or what the specs are. He gave it to me to try to repair, being the only Mac guy in the Here's the deal. It charges the battery, and but won't turn on. I tried the PMU reset.
View 6 Replies View RelatedIt just started getting really hot quickly for about a week before it didn't turn on. I would have it tilted so that its not flat, hoping that it would give it more air but it didn't do anything. I don't even need to do much to get it really hot. And I shut it off every night, so it should get to reset itself. I haven't done anything different that I haven't before. Any fixes please!? Also what's really weird is that it gets hotter and hotter even when it is off and not even plugged in.
View 4 Replies View RelatedI have a PowerBook G4 1.67 that shut itself down sometime during the day yesterday, and will not power back up. It's completely unresponsive to the power button, with no signs of life whatsoever.
I've tried resetting the PMU. There has been no new hardware or software installed. This has been tried with 2 batteries, and 2 AC power supplies.
There is inconsistency with the color of the AC power supply tip, as it doesn't seem to indicate the strength of the battery. Regardless of which battery or how much charge is left, the tip is Green, and will flicker Yellow very quickly once, when plugged in. It was Green following the initial shutdown, Yellow when I placed a dead battery in it, and then eventually turned Green. Now, it seems permanently in the Green / flicker Yellow state.
It did fully charge one battery while like this.
Basically, the iBook G4 (last revision) will not turn on. What is happening I press the power button, the iBook chimes, HDD makes its regular "computer was just turned on" noises and then the computer sits at the Grey Screen and the little swirly loading thing comes up and nothing else happens. What happened before the issue I was browsing the web last night and before turning it off for the night I ran MainMenu's batch tasks. I have been using MainMenu for several months with zero issues up till now. My sister said she needed to use my computer for a few minutes so I turned it back on. It sat at the Grey Screen for 15 minutes so I force shut down and tried again. After another 15 minutes I went to bed (it was getting late) and left it to see what happened over night. Somewhere in my 8 hours of sleep the computer gave up and turned itself off. I have not heard any tell-tale signs of an HDD failure - no clicking, buzzing or scratchy noises. Possible Culprits UNO - has been installed for over a month but it does have access to system files so I'm not clearing its name. MainMenu - Been using for a while but it was the last thing I did before the problem arose. What I've done to fix it - Reset the PMU by pressing Shift + Option + Control + Power Button - Boot off restore disk and repaired the disk in Disk Utility. The volume bit map and volume information needed repair. is the poor sucker dead?

View 8 Replies View RelatedI have an old iBook G4 (1.2 GHz, 1GB RAM, 80GB HD) that is quite slow but physically in great condition. I want to strip all the unnecessary crap off it, leaving just what's necessary and Firefox/Safari, Adium, SlingPlayer, TextEdit (OK, I guess I'm leaving one unnecessary item on it) and making it as fast as possible, as my newer MacBook Pro is working fine as my "main" computer and I mostly just want a secondary road machine to tote around. Should I just do a complete reinstall of Leopard on it or is there a better way to retain what I do already want before using the nuclear option?
View 4 Replies View RelatedMy iBook G4 is refusing to turn on. Yesterday it started going really slow and pressing the power button wasn't bringing up the usual options, so I held the power button to switch it off. On turning it back on it got stuck on the screen with the Apple logo and spinner for a long time so again I powered it off with the holding of the button. I then let it cool down (it was really hot) but now when I switch it on the spinner spins around 6 times then it turns itself off. It is still chiming. I'm away from home and don't have any discs - anything I can try or is it time for the Genius bar?

View 5 Replies View RelatedI bought an ibook a little while ago because I wanted a small, simple notebook and I love my home iMac. I found one for a good price on eBay and when it arrived everything seemed ok. I wanted to re-install the OS and set everything to my specifications because I was having a little trouble with some of the apps. Anyway, I went through the lengthy re-install and just as it finished counting down the seconds to completion, it shut down. I thought it might be in sleep mode because the little white light was on, so I hit a key and the light went off but nothing happened. Nothing on the screen, no HD noise, nothing. I'm at a loss because I really don't know much at all about hardware or software, which is why I liked the user-friendly Mac so much. The only thing that tells me it's getting power is the little green light at the power connector. I tried a PMU reset (there's no reset button on my model so it was a button combo of shift-ctrl-option-power I think) but that didn't do anything.

View 2 Replies View RelatedI have an out-of-warranty 2005 iMac G5 running OS X 10.5 in my bedroom. The screen is very unreliable to the point where it stayed off all the time or gave weird colors and I had to purchase an external monitor (via mini-VGA). I have installed (successfully) spanning tools to allow both extended desktop (2 dual monitors) and mirrored display (2 monitors showing same thing).
However, after hooking up the external display, the iMac's bright display lights up my bedroom. I want to turn OFF my built-in display (i.e. no backlight) and have my external monitor act as my main display --- avoids having two displays eating electricity. Is this possible? (using any Terminal commands?) I don't want the computer to sleep, just to turn off the main display (even manually removing wires will work, if I can find a how-to guide on this!)
I bought a PowerPC iBook G4 second hand from ebay, it was working fine until one day, it stpped turning off. My lecturer told me to hold the power key down until it turned off.
This was fine for a while but now it won't turn on, whenever I try to turn it on it just comes up with a grey screen and wont load. I have important information on my Mac which is vital to the course I am studying, I have tried turning it to hard drive mode to try and get the information from it but it doesn't show up on my other mac.
My ibook G4 died last night. After having some trouble with the battery (i have to replace it), the laptop finally did'nt turned on never again. Although is plugged with the power cord, the computer does'nt make any sound and it does'nt turn on, it does'nt even sound the cooling fan spining.

View 8 Replies View RelatedI am dog/housesitting for my inlaws. Yesterday, before I left my house I shut down my iMac as always and for the heck of it, unplugged the computer, modem, and router stopped home today, and decided to hop on the computer real quick. plugged everything back in and the computer will NOT turn on. No noise, no lights, nothing. It was fine yesterday--I shut it down, unplugged it, and plugged it back in today---now it is completely dead! So I tried other plugs and no dice. Never had any power or shutdown/starup issue before. I called Mac---but outside of driving an hour to the Apple store--it wasn't much help. The guy did say it was most likely the cord. I would be wiling to try that--as it would be a cheap option, but it looks like I may have to drive to the Apple store anyway to get a cord that fits. I also tried resetting the PMU that Apples site recommends--and nothing. Any suggestion would be great. With the holidays the thought of dropping big $$$ on computer repairs is not appealing.

I know the "Using imac as external monitor" topic has been adressed in previous posts and it apparently can't be done. But this is slightly different.
I have this Imac G5 24" that is currently out of order. (won't detect hard drives when powered on 90% of the time and when it does i am experiencing ridiculous lag and random shutdowns...not to mention crazy overheating)
I sent it to tech support and after changing the hard drive, power supply etc.. and still not seeing any improvement i just stopped sinking money in repairs and got a new imac.
So now i just have this useless imac laying around and i figured i might as well try and recycle it into a secondary monitor.. I don't mind hacking it open since i have nothing to lose. I was just wondering if it could be done and if so would it be very complicated? I would rather pay a few hundred dollars in wires and IT than buy a cheap external monitor since its already a decent quality monitor and it matches the new imac
After having inserted a dvd borrowed from the library which my Imac had a really tough time reading, I turned off my Imac as usual. Since then when I turn my mac on the fan starts roaring and i don't get beyond the first white screen with the sort of clocked wheel just going round and round. I don't have a clue to what to do.
