MacBook Air :: Won't Start Up - No Sound Nor Any Type Of Activities
Nov 30, 2014
I have a Mac air (bought it last year) and today won't start up at all!!it does not produce any sound nor I can hear the fun. no video .no activity at all. The power cable is connected and light is green.
I don't know what I did. but I have any item in Keychain access named system I can unlock with my administrator Password from within Keychain Access. It doesn't show up on the Keychain Access item in menu bar. And I get message along the lines of. OSX requires you type password (which happens to be same as administrator password). there are only three items in it. a Dashboard advisory certificate, and the names of two airport Router items I have listed and each password for them
G4-500 1.5GB memory OSX.4.11 on 80GB WD drive set as Slave. 120gb Main drive set as Master with slave using OSX.3.9.11 There appears no way to set preference for this system Key Chain to automatically open. suggestions? I think I also have a complete and Total melt down of the key chain system on my X.3.9 Drive Because I can't get keychain, accounts, Installer, Stickies, and Pacifist to open. There may be other but applications such as word, Acrobat, and all web browsers an mail/news client I have work fine. I deal with that issue after I get this fixed.
For a number of reasons, I cannot use a web based mail program and use Apple Mail. Is there any way to synchronize my laptop and desktop mail activities so whatever happens on one happens on the other?
Since the Safari 5.1.5 update, one function of my bank's bill pay can not be accessed and defaults to a different page. I checked with the bank this morning and it seems the latest update of Safari blocks entry into the Medivante bill pay function which operates within the shell of the bank web page. The browser gives no indication that that page is actually from Medivante. Essentially, Safari sees this as a third party and blocks the browser from even getting information, not just cookies!
Bill pay can be accessed from the main page to set up a payment since that is a flow though using the bank information or setup, but is blocked if doing any editing which requires the site communicating directly with Medivante within the bank site. This can only be gotten around by changing to NEVER blocking cookies. Having the setting of blocking 3rd party and advertiser cookies no longer can be used with the bank site if I need to access the bill pay function. This doesn't even seem to be an issue of cookies, but is blocking access to bank/Medivante information.
Because the never setting is a risky one that only a fool would allow, I have to change the setting while I am in the bank site, change back cookie preferences when done with the bank, then close Safari before I do further browsing (seems the new settings don't always take effect until the browser restarts). This might be for our protection, but Apple has broken convenient use of the bank site that had worked prior to the update. I do not know who else might be affected. My bank is not one of the "big name" financial institutions but is certainly not a minor institution.

I'm doing my best not to panic here but I'm sure you can feel my pain. I got up this morning, made my coffee and opened up my MBP to start my day.
I can hear that start up sound but the screen is completely black. Nothing. It was fine yesterday and I didn't do anything different when I closed it to put it in sleep mode. But now it won't wake up. I pulled the battery, let it cool (seemed a little warm since I just started it)....still black screen.
I recently purchased a 13" 2.26 stock macbook. It's perfect, screen is good (no scrolling issues or purple blues) with no dead pixels, no slanted keys, and no scratches.
I updated the firmware that addresses the SATA 1.5 issue. After the update, I reset PRAM. I held down the buttons till I heard the second or third startup bong.
Here is where it gets funny.
Now, when I reboot or start up my computer, the start up noise is loud. Even with headphones plugged in and also the volume turned to its lowest setting (even with volume turned off). Eventually, to control the startup noise, I had to install the startupsound program in my system prefs as mentioned on other threads and that has seemed to control the startup sound.
I was wondering, if by resetting the PRAM if I have harmed my computer in any way. Should I be worried about deeper issues with my computer since the startup sound was not previously being affected by reducing the volume to zero with headphones plugged in?
besides leaving your computer on mute is there a way to turn off the startup noise on a mac? When i come late to class and want to bootup my computer, the apple startup noise draws attention to the fact that i am late and booting up my macbook.
I'm trying to help a friend get into her old PowerBook 165 but we can't get it to boot up. Whenever it turns on we get the BONG startup sound and then it just flashes a floppy drive with a question mark. We can't get it to go any further and we're at a loss for how to get the files off of it now.
Just bought today, brand new mac pro 8 core 2.8ghz. I get a weird click on both boot and start up or when I put the computer to sleep or wake it. It's a single click, imagine the sound of someone lightly flicking the side of an empty Pepsi can. It's not random, I can make it do the sound simply by unplugging or re-plugging the power cord in the back. Is this normal?
My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?
I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.
I have this powerbook from 2005 and no problems up to now..ohhh no!
A couple of days ago started to occasionally make a clank clank noise and getting stacked on the spinning colour circle, only manual restart would do it.
Thought it might be the hard disk as it is a bit old and i never replaced anything on it, shacked it and a noise of something loose would happen, so i thought of opening it up and see if i could reattach anything loose....anyway i started unscrewing following instructions, couldn't get memory out...every screw seems different and so i gave up, put it all back together, praying that the screws are all in their right places and hey, now it wont even start, not a loose sound when shaken though, but not a bip not a light, black screen, nothing...only sign of life is the green light under the num block key and the capitals arrow also starts light
I am running the 27" iMac with dual hard drives and have recently upgraded to Lion. Two things are happening.
1. On cold start / boot up, my system has no sound. And by no sound I mean - no sound. When I go to the Sound option in System Preferences, everything is greyed out and I can not adjust or access any of the controls. The only solution has been to immediately restart my computer. After restart, everything is fine.
2. On cold start / boot up, sometimes I receive a pop up telling me that TestGen is not installed properly and to please re-start. Of course, since I have no sound I'm automatically doing that.
Lastly, and I'm not adding this to the list because there is already a thread about it . . but I will mention it I am getting error messages trying to play certain videos "This video requires Quicktime which is not supported by this version of iTunes."The workaround is that you apparently have to delete the video from your Library -- DO NOT DELETE FILE FROM HARD DRIVE -- and re-add to your Library.
So as the title says when I boot up my iMac, on occasion, it seems to have the "Updating" Status bar, then the mac boots normally, then the sound is disabled. As I said though this dose not happed all the time but when it dose the only way to fix it is by rebooting the iMac once again.

I got a Powerbook 190 from my grandfather. He didn't give me the cord to plug it in with. He gave me the cord that has the big box, that connects to the computer. It was missing the cord that goes from the box to the wall. I read that it said to ONLY use an apple cord.My step dad said "that's not how electricity works." and gave me a regular, random computer cord. I was unsure, but plugged him in anyway.
He worked perfectly for one night. No problem at all. Booted up right away. I played on him for a few hours. It was time to go to bed.
He hasn't woken up since. He's made the start up sound a few times, but never starts up. I've pushed the reset button on the back a thousand times. At least what I THINK is the reset button. They just say under the video out port, but I don't know what that looks like. What I'm pressing is a small, very flat, wide (but still very small) rectangle of a button. Nothing. I've held it down for 40 seconds, 4 or 5 times. I've taken the battery out, and then held the reset button. Nothing. I've tried everything I know to do, for about a month now.
I left him alone for a few weeks. I plugged him in today, and it made the start up sound, and then nothing.
Can I save him? How? Should I try an apple-specific computer cord? Do I need a new battery? If I did, wouldn't it start up with the battery out, but still plugged into the wall? Fried motherboard?
I even found a freaking airport card that'll work with it, and an external floppy disk for my new mac, so I can transfer files from one to the other. I was so excited about him. And my dreams were crushed.
I understand the steps needed, but how many times should I reset the PRAM and how many times should I here the startup sound (in total) before releasing the buttons?
My new imac makes a very loud noise on startup and a whirring noise comes from computer screen had it just over a week should I return and get a replacement.
This situation began when I put my Imac on sleep. After, the screen turned on in black whit the cursor but I couldn't do anything.
Then to rebooted the machine, the apple logo and sound began fine but the screen turned off, so moving the mouse the screen turned on in black with cursor.Â
I'd tried many ways, resetting the PRAM, SMC, repairing the disk and permission, analyzing hardware, repairing fsck files.
Suddenly, when I entered in Verbose mode, mi imac brought into user choose screen and worked fine, but when I shut down and tried to start my mac in the next day, it didn´t work again.Â
This started happening randomly earlier tonight, and I haven't managed to find a fix just yet.I was encoding a video file for quite awhile (I don't think that parts important, but I thought I'd include it anyway) and then I tried to play a youtube video. I noticed there was no sound, so I tried to up the volume using the Volume Up key on the keyboard. The volume visualisation appeared on the screen like normal (albeit a bit laggy), but the sound still didn't change, neither did I get the usual 'click' noise you get when you change the volume.I went looking into the sound options in the system prefs. only to find that the Output Sound device was headphones. For a test I plugged in some headphones to see what happened and, low and behold, the Output Sound device changed to the Internal Sound and my speakers were working again, but only with the headphones plugged in.
When surfing the net (like right now) or just letting it idle, my hard drive makes a slight "clunk" sound like the HD arm is hitting the edge of the case (or maybe starting up and shutting down?). There seems to be no loss of performance. I did a disk verify and everything is OK. Should I be concerned?
I have a person that sent along this video and it concerns me that a hard drive would make such a noise. It's unlike anything I've heard in a drive. He claims the original owner installed a new Seagate 7200rpm in the book, and that it mostly happens when loading a web-page on Safari.
Every time I look up "hard drive click" I get the SMS triggered "tink" but this notebook is not in motion and instead makes a "ca-chink".
For some odd reason, I have been experiencing some creaking when I move the display of my Unibody 15.5" Macbook Pro. At all. It just is very annoying, as it has a distinct plastiky sound to it, and it was not there to begin with. I don't know if this matters, but I have a Speck clear case that I used, but then I took it off because it seemed to be twisting the display a bit. Is this creaking a known issue with the Unibodies, or is it just because of the Speck case? I have never dropped my computer, and it has never been mistreated. It just leads its life on my desk or in my laptop bag. Any ideas?
My computer won't turn on. Earlier today while playin music it just paused itself. I minute later it resumed. Then tonight it just shut off instead of sleeping and now it won't start. All I can get if I'm lucky is the start up chime and a super quick flash of a white screen.
