Powerbook "turns on" no display, weird sound?

My G4 will not start. The familiar chime comes on when I press the power button, and it sounds like it will start. However, no video shows up and no hard drive activity seems to be happening. When I held down the power button and shift key together, the little lid-button light blinked a bunch of times, and a weird sound happened (sort of a low beep)
Any ideas?

Has your clock battery been replaced in the last 4 years?
Is your data backed up?

How do you turn the weird sound off when sending a text using the iPhone 4S?

Go to Settings-Sounds-Text Tone and change to None. You're referring to the sound when posting a message to someone else, correct? The only issue is if you set to none, you will not hear the incoming either.

Windows 8 "Turn off the display" setting not working

Hi all, I've got a TP W520 which I upgraded to Windows 8 with all updated Lenovo packages including the power mgt driver, Lenovo settings dependency package, and the newly installed Lenovo settings metro app. I'm seeing the following problem when trying to set a time for the monitor to shut off under Control Panel -> Hardware and sound -> Power Options -> Edit plan settings: - If I set any time other than never for "Turn off the display" such as 1 hour for example, the monitor will get turned off as soon as the screen-saver launches from the Windows 8 Lock Screen. - I'm not seeing this same behavior if I let the screen-saver launch while sitting at the desktop screen, problem is only seen from the Windows 8 lock screen. You can test this as follows: - Set "Turn off display" to any time i.e. 30 min - Change your screen-saver to launch after 1 min to test this - Type ctrl-alt-del then click lock to enter the lock screen, then let the screen-saver activate after a minute. - Once the screen saver tries to start, in my case, I see the monitor getting turned off and the screen saver doesn't even start. The monitor shouldn't get turned off until 30 min elapses. I'm suspecting some kind of bug with this which is still outstanding and I look forward to feedback from others on this issue. Thanks, John

My macbook pro is making a weird sound, please help?

Hello,
i have an early 2011 model, it was running soo fine until now.
its making a weird sound, to describe, it sounds like a small *trrr* at normal state, and at high, intense states, (playing games..) it turns into a loud *trrrrrr*, but, if i hit it gently over the keyboard, it goes away, then comes back.
please, i dont have an apple retail store in my country, i need help from here, help me.

first thing to do is to buy a new hard drive and an external drive before it fails so you won't lose your files.
once you've done that, put the new hard drive in the external drive and open disk utility.
format/erase your new hard drive as MAC OS EXTENDED Journaled.
After that has been done, open carbon copy (if you don't have it, you can download it for free).
Once carbon copy is open, click on clone your hard drive. Source drive is what you're using now and your target drive is your new hard drive.
Once carbon copy is done, turn off your macbook, open the back of your macbook, take off the hard drive and install your new hard drive.
After you've done all those, turn your macbook back on and you're back in business.

Weird sound coming from above F1-F3 keys - locks computer up

I just got my MacBook Pro back from Apple and they did not fix the problem below (although, they fixed a number of small things, thankfully, like the bad speakers, crash from sleep, flaking keyboard paint, etc.). I am taking it back in today and need to figure out how to best describe this problem or point them in the right direction, since it was not addressed.
About a week ago, my MacBook Pro starting making this weird sound above the F1-F3 keys, something resembling a loud hard drive accessing sound or a sparking sound. When this happens, the cursor turns into the colored spinning beach ball, locking up my ability to interact with my computer. This continues for maybe 5-10 minutes. Then the sound stops, and the beachball goes away. But, it could come back anytime. This makes working on my computer virtually impossible as there are times it happens 3-4 times in an hour. It comes randomly, at any time. It seems some likely if the computer has been running for awhile and is overheating, but it has been known to come on bootup sometimes, as well.
No idea what his is - I already had the Main Logic Board replaced and it didn't help, so it must be another component up there underneath the F1-F3 keys.
Any expert advice? Thank you.

Volume troubleshooting - weird sounds

Hi,
i just bought an iBook G4 (12'') and when i first turn it on and want to change the volume with the F4 and F5 keys, instead of the specific sound supposed to come out (like a bubble) it kind of bugs and takes a while before actually carrying out the command...
I thus hear a low, and sort of weird sound.
However, when I open iTunes, it works just fine... It's no real problem actually but I'm afraid it might only be the tip of the iceberg.
I have to admit that I did give it a slight bump before noticing that problem, but then again I only bought 10 days ago without yet having made full use of it...
(I also checked the CD burner and it works fine, so how could a bump not affect the -sensitive- CD burner and affect the volume keys... ?)
does anybody have a clue... ?
THank you very much.
iBook G4 12'' Mac OS X (10.4.2)

Do you have a lot of applications running when it does this? I find that when my computer is doing a lot, there will be a delay before it changes the volume level. The sound is also sometimes a little different. Does it do this when you don't have anything besides the system running? If not, I wouldn't worry about it. It's just because the computer is using a lot of it's memory at that moment. You can always add more RAM, and that should solve it. But it's not that big of a problem

Macbook Pro V10.6.6 making weird sound

My Macbook pro has started making this weird sound suddenly starting this morning. It's coming from the right side and the sound is very hard to explain. It's somewhat krrrrrrr, something like an electric, static sound. It's hard to hear at times but it can get quite annoying when it gets loud. It comes and goes. I tried restarting my computer but the sound still remains. What could that sound be? I hope all my internal hardware is fine
Please help me out here!!

Try doing a SMC reset, it may take a couple of try's. The instructions are:
*SMC RESET*
• Shut down the computer.
• Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
• On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
• Release all the keys and the power button at the same time.
• Press the power button to turn on the computer.
*PRAM RESET*
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.

Making weird sound every time I switch songs. Really annoying..

Ok, so my iPod Touch makes a weird sound every time I switch songs. It is the exact same sound the iPod makes when connecting the USB cable to my macbook. I tried turning off all sound effects, didn't help.
Any idea? Any help would be greatly appreciated. Thanks!

Strange. Which phone model? What file format is used for the songs? How did you transfer them to your phone? Where on the phone do you put them?

I have a stuck CDR disk in my MacBook. I have tried everything and nothing works. When the computer starts it makes weird sounds and also when I try to eject it. Nothing Works! Please Help.

I have tried everything and nothing works. When the computer starts it makes weird sounds and also when I try to eject it. Nothing Works! Please Help.

I had that happen with a MacBook. It turned out that the metal case above the slot was slightly bent down.
Putting a flat blade screwdriver in the slot and gently twisting it to move the metal case up allowed it to eject. Don't put it in too far you only want to bend the case not the drive.
The case can get bent down by picking it up with your thumb pressing down on the case above the slot.

The harddrive makes weird sound and is dead!

Hi
I bought this fancy car stereo with a aux input so I could listen to my iPod in the car. Whoever had the car before me had a magnet attached to the dashboard, for holding onto her cellphone. Well I looked at my iPod, I saw a metal cover and figured it would be perfect to have it on that magnet. Well, 2-3 trips later my iPod won't play anymore and when I try to turn it on it makes this weird sound as if something is scratcing in it, internally. Then that white screen comes up with a sad iPod-smilie. When I plug it to the computer it just keeps trying to start up, repeatedly.
Have I destroyed my baby?
This *****.

yup. its dead. this just happened to mine, oh, a couple weeks ago. its probably not due to the magnet, though. when i took mine in they said it was most likely because of some kind of physical trauma the ipod had been through, sudden or over time, such as dropping or just being moved around a lot. if your ipod is under warranty, though, you shouldnt have any trouble getting a good-as-new replacement at the store. when i went there was a pretty long wait, but once i got there it proceeded very quickly. i must say, i expected some kind of long ordeal, but all that happened was i showed him the noise it was making and the sad ipod icon, he said "ok", did something on his computer real quick, and went into the back and got me a replacement. if your ipod isnt under warranty anymore i suggest reading whatever information you have on ipod support(i dont know if you saved the little booklets in the box or not, i did). i read it all before i went in, and most of it is just protecting themselves in case they treat you like crap(which may have been the reason i expected them to), so i wouldnt get your hopes up too much if your ipod is no longer in warranty.
good luck

Midi not out/ weirds sounds

Hi , when i hit rec i have weirds sounds from my exrternals instruments or when i start logic.
Does anyone know this problem ? Is it a bug ?
Thanks for help
Imac fusion drive 2,7 intel core i5, os 10.9.1, Logic pro X 10.0.6

It's probably one of the recent Apple updates that hosed your Logic performance, try turning of Airport and see if that fixes the problem.
Don't know if the Logic 8.02 + OS 10.5.3 fixes the problem as I don't use wireless, just a big ol' honkin' cable.

Weird sound when entering optical-in cable

My new PB 17" hi-res makes a weird sound when I insert the monster optical cable into the optical-in jack. The sound it makes through the speakers is the sound of air getting released under pressure, at a very high sound level.
The optical cable is attached to a Sony DAT recorder. If the recorder is on before inserting the cable, the weird sound comes immediately when inserting, if the DAT is off the weird sound comes when powering on the DAT. The same happens when taking the optical cable out.
Since this happened the first time the system sounds where gone (like when you empty the thrash bin etc.). After a restart I sort of got them back. The only system sound I get is a very tiny, short bleep, verry different from before. Also now sometimes several keys on the keyboard produce a sort of bleep (not mechanical I think) when I use them.
Anybody experience this too? My previous PB 17" (G4 1,67) didn't have this weird sound, whether the DAT was on or off.

Mac_Dutch, I think that as long as you have the Dat recorder on you will get this sound. This is feed back the same as plugging in a Guitar into and Amplifier that is turned on..
On restart you will notice a similar sound momentarly as the computer either comes awake or restart as it boot up and starts all the process...Cheers...Don

High beep + bass makes weird sound, Inspire P580

Hello,
I switched rooms today. And now when I turn on the 5.1 using the audio controller, I get a very high beep. Before, the beep wasn't this loud. And also when I turn up the bass, it makes a very weird sound. I check everthing, everything is plugged in correctly but I don't know what to do. I know it's not the software.
Hopefully somebody can help me.
Thanks by advance
Jascha

I have a GigaWorks S750, today i turned on the speaker to listen to my computer, i started the music and i only hear big distortion, i turned of the music and found out that the speakers putting out a frequent beeb, and as i turn up the volume i get a tone of higher and higher frequency beep but not a louder beep, the subwoofer just makes some short noises sometimes.. and i have checked all the cables and they are ok.. i listened directly from my soundcard with my headphones and it sounded ok, i also tried my headphones by putting them into the headphone port on the decoder and it sounded as it should there two
i am almost sure this has something to do with the electronics in the subwoofer to do, cause i dont belei've 7 speakers would stop working at the same time.
This is so bad, i had just gotten my Xbox360 today and now i cant use it on my suround system.

PowerBook G4 17-inch Display

My PowerBook G4 17-inch display screen cracked. does anyone know where i can purchase just the screen?

You can buy them on eBay brand new and/or used.
No other companies I know of sell just the screen. They sell the screen but also it's part of their service package such as a screen replacement service.
Apple of course, does not sell parts to customers, such as an LCD screen.
There is however, one company I know of that says they sell Apple-compatible screens since Apple does not make their own screens, but gets them from OEM suppliers, to which they in turn get theirs.
And I just found it, after looking for it on the web. Here they are:

** Make sure it is the right screen for your model, wherever you do get it. If you opt for a screen replacement service, they will get it right for you. But if you opt to buy it from someone who sells it by itself, make sure it is compatible and the right one. For instance, don't get a high-res screen if yours doesn't have one to begin with. You won't be able to use it because of the video card in your machine. Same vice versa... don't get a low-res screen if yours is a high-res one.
