PowerPC :: Hitting The Power Button On The Unit Or Keyboard, The Units Screen Makes A Noise?
Mar 16, 2008
First of all, Noob imac owner here. I was just handed down an old imac g3 400mhz desktop that doesn't power at all.When hitting the power button on the unit or keyboard, the units screen makes a noise. No hard drive or green light comes on at all. At dead silence in the room, i can hear the screen flicker, like a tv would come on. I went to go about and read a few problems before, replaced the battery and even tried a new power cord. Any Ideas?

On my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.Any ideas what to do? It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.

My trusty PPC g5 from 2004 has died, or at least it won't start. It shows the grey apple screen, but no spinner, and after a few minutes the fans kick in and build to a wind-tunnel noise.
I don't have a backup of this machine, or it's other drive, so I am nervous about taking it into Apple where they might just wipe it.
Also, I surprisingly CAN start it up in Firewire disk mode, and both drives seem to be OK when accessed from another computer.
So I've copied off the most important things, and I will probably try to make clones. But before I finally cart it into Apple (where it will probably cost more than its worth to fix it),
Info:
Powermac G5, Intel iMacs, Mac OS X (10.6.2)

Just opened my new macbook pro 15" and when i turned it on (and every time i turn it on), it makes a strange noise. seems to come from the front but it stops after a second or two. almost sounds like it's a disk drive spinning up. Is this normal? It doesn't sound like it's anything bad, it actually sounds like a standard pc based laptop sounds when booting up. I just thought the macbooks were supposed to have almost whisper quiet components. I still love it, and I'm glad I bought it.

My fans are constantly going on my g4 powerbook and the noise drives me nuts. I do all sorts of work - graphics (CS2), music recording, multimedia... but even when I am just not doing anything intensive the fans are on.
The fans are at full speed now and the temp reads 37C / 98F. I've used an icurve since I got the machine.I've put up with this noisy sound for a couple years now. One person said I need to clean the air vents, like dust is causing the noise. Does anyone know about this?
its a g4 titanium powerbook 867 mhz 768 RAM (ancient I know but it still works!)

My mac has worked great for the last 2 years since ive owned it and it just started to act a lil differently about 2 weeks ago. I started to notice that it started to act a lil slower than normal when i was surfing the internet. Then a couple of days ago the computer started making like a buzzing noise , kinda sounds like interference . Like when a cell phone gets close to a stereo system. Sometimes the noise will go away and then when i start opening diff app. that use computer cpu the noise happens again. It was just making the noise and i was dealing with it until the computer started to crash. It would look like the screen was on fire and everything would just freeze. Do you guys think it is the hardrive ?????? and if it was what would be my best option for fixing this. Can i save the stuff that is on my current drive ?? I have a bunch of stuff that is very important on this hardrive.
whats the best place to buy a hardrive if i need one ? and can i buy a hardrive that can hold more than the stock 74.53 toshiba MK8025GAS ?

- When I clean the screen with the included cloth or any cleaning cloth, the screen makes a clicking noise. As if it's like not flushed against the bezel. This only happens on the left part of the screen from, top to bottom. If I wipe in the center, no problem at all. I was wondering if anyone of you is experiencing the same problem? Btw, I also have the lines, but its very faint and I don't notice it as much as the my 3rd replacement Air, which I exchanged for this one. The Apple Store said that if I had any more line problems with this one, they won't replace it anymore and they would just try and replace the screen. I don't know if my problem is a common one and worth it to send my computer out to get its screen replaced, and who knows, maybe the replacement screen might have the lines and that's why I'm worried about getting the screen replaced, in addition to being out of my laptop for a couple of days.

My macbook Pro makes an occasional noise that sounds like hitting on a drum (specifically congas). Or for want for a better description, it is the sound you hear when you eject a memory stick from a windows based computer.

I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.

I'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.

Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?

Before the most recent update, hitting the green button on iTunes would make it tiny in the corner, now you have to hit apple-shift-M. I find this annoying, is there any way to go back to just hitting the green button?

I upgraded to iTunes 8.1 when it showed up on Software Update. Since then, I've noticed that when I hit the Play button to play anything in my Library, there is a long pause (about 6-7 seconds) before the audio file starts playing. Have any of you had this happen to you?
This is on 10.4.11 on my iMac G5. My drive is getting short on space (and I'm aware of issues do to short drive space ), but it didn't do this before the upgrade to 8.1. Let me know your thoughts...

Note the F keys on the 11 inch, and the new power button. What's missing? Also note the lack of the word 'backlit' in the descriptions for either machine. Both machines have the same keyboard, just to eliminate the power button in the name of aesthetics.

I know I can get the bulk of it here: [URL:..] But is there a controller board? I can't find any documentation on this thing. I want to use it for a PC. Making an acrylic top is no problem. Just looking for pin-outs, dimensions, and maybe some pictures of someone else dissecting one.

I was just wondering if anyone knows how I can remove my eMacs power button, the one that you press to turn the computer on. I kinda wrecked mine and I want to "pop" it out to have a look at it. Looking at replacement costs they are like 50 bucks so I need to try what I can before I fork out for a new one.

This is a mystery to me. Long story but the gist of it is that I found if I hold down the power-button on my iBook while it's off it goes into some weird mode. i.e. fan spins, disc spins, sleep light flashes and a tone comes from the speakers.Is this some sort of hardware test mode? Is it going to blow up? Is it resetting something?

I have a 17" G4 1Ghz iMac, we used it until 10 months ago when I got my new 24" Intel 2GHz machine. That new 24" iMac is now in the basement craftroom as the digital hub for pictures/video/etc., while I brought the 17" G4 1Ghz iMac out from my closet for the upstairs loft general web surfing machine. It worked for 2 days and upon shut down would not re-start. I could only hear the fan and nothing else. If I held the power button for 10 seconds upon trying to start up there was a chime that sounded for a few seconds. Once the fan is making small sound, nothing else, if I hold power button for 5-20 seconds the computer will shut down (fan turn off).
Did some online checking, found article on PMU, so I did try and re-set PMU via the apple support article.Resetting the iMac (Flat Panel) Power Management Unit (PMU). Still, no re-start. It was running the latest 10.4.x update upon being put away for 10 months. Here is a picture of the bottom, the red light is on upon trying power on, my finger is on the PMU reset button. Is there any other diagnostic thing I can do? Is there a battery on this logic board that I can check/replace? I'm 100% ok at taking it apart and trying anything to fix it.

Got a tricky one here: powerbook G4, 1.25ghz, 1GB RAM (2x512), 80gb HD, APX, 15" LCD, serviceable battery, SuperDrive, OS: 10.4.11. It was brought to me with a boot problem: Computer turns on, gives the start up sound, backlight comes on, apple logo shows, spinner spins... then you get the dimmed screen, large option icon and "You must hold the power button and restart your computer": a kernel panic. I've seen this a few times before and the last time, I fixed it with a new hard drive and the removal of RAM from a bad ram slot.
What I did was:
1) Replaced existing 80GB HD with a backup 30GB drive. Then booted with a Tiger CD (the computer won't start with my disk warrior cd, nor with a tiger DVD). I was able to install Tiger and restart the computer. But the airport card doesn't show up. I tried a known good airport extreme card and this too has not shown up.
2) I hooked up the 80GB drive to my PC via MacDisk and checked it. Sure 'nuf it had loads of problems. MacDisk went through and fixed it (I'm not sure what the problems were as I'm new to MacDisk and don't know what it's looking for and fixing when it does).
3) With the computer running the 30GB known good HD, I started having the same kernel panics so I removed the first RAM chip (512MB) and tried to reset the PRAM.... here's where it went wonky. (I know, only change one thing at a time...)
4) As I said I tried to reset the PRAM (Option, Command, P, R, at start up). While I can get the computer to not boot, it won't restart. I don't know if this is just unique to this machine. Next I tried to reset the NVRAM and again got nothing. The screen wouldn't come on at all. After about three or four resets, the computer did start in Open Firmware mode. I reset the NVRAM from there and restarted (reset-nvram, reset-all). Still nothing on restart.
5) After trying to start it 15 times like this, I swapped the bottom RAM card to the top slot and removed the airport card (again, I'm stupidly trying to change two things at a time). BAM, computer boots... I put back in the 80GB drive that's been "fixed" by MacDrive and BAM, that boots fine too.
So then I put back in the airport card and it will boot, but won't recognize the airport card. I've re-seated it about a dozen times and have used terminal cleaner on the card and on the socket for the ribbon cable from the card slot to the logic board. As it sits, I can't get the airport card (either of the two) to show up at all. I did realize that the open firmware did reference a problem, but I forget the code now and when I looked it up, the references were to a failure of the airport card, but there were also more general references, so I can't be sure.
I'm thinking now that it's the airport card controller on the logic board, the bottom RAM slot and a corruption of the hard drive. Yes, there was a history of moisture into the device and I think a drop in it's past too. I'm the Mac repair technician for the people at the local bike shop, so I get to trade my repair work for their bike repair work. The problem is that they ride their laptops like their bikes, hard and greasy. I'm really wondering about ways to get the airport card back up and running. Or, baring that, a good card-based wireless adapter that I can slide in.

I have a G5 dual 1.8 power PC...Bought some ram put it in & booted up. Then a red light came on the logic board behind the power button. The machine wouldn't turn on....I called apple care & we rearranged the ram, now the red light is gone but my system still won't boot up. The white power light blinks every few seconds... the apple store told me sorry can't help because your machine is vintage. Even if my logic board is fried is there a place to buy one on the cheap?

I just bought a new Logic Board for a 1.25Ghz eMac and I've put almost everything back together after installing it until I ran into a problem. The power button cable that runs from the power button on the casing into the logic board has no connector on the Logic Board itself, now I have an old logic board that whilst being broken has a connector on it but I really don't want to have to solder the connector on for fear of breaking the logic board.

At the moment I have 2 MBAs at home and the displays are different. My first MBA had some build issues. So I called apple and they just sent me a second MBA. The second MBA's display lighting is much brighter especially at the edge of the screen. So the colours are worse and the black is not black any more. So I'm not sure what to do: I want the screen of my first MBA and the build quality of the second one

I recently purchased a new (to me) iBook Clamshell off eBay running Os 9.1. This is my first Mac, It has a 6 gig HD and the HD seems like its spinning really loud and it makes chirping sounds whenever I change the screen saver
Does this Mean the HD is failing? Should I get a new HD

I was attempting to replace the hard drive in my eMac, but for instructions I HAD to follow some darn take-apart guide that said pull out the connection for the power button cord from the logic board. I didn't know that it was SOLDERED in there, and now I can't complete putting my eMac back together without doing so.
Can this be fixed without having to send it to Apple? Does it HAVE to inolve soldering, or is there an alternative? Is there a way I can temporary have my eMac power on until I get the connector fixed?
