I have a macbook ALU. When I stay in bootcamp with windows if I put the brightness between 30 80%
I listen a high pitch with nvidia drivers if I uninstall the drivers I don't have this problem.
Whenever my screen is not turned up to the maximum brightness, a really high pitched sound is emitted from the laptop. If you've ever heard the "mosquito ringtone", that's basically what it sounds like. Really odd. It's definitely got something to do with the screen brightness, and I basically can't use my laptop at medium brightness because the sound drives me a little nuts. Turning the brightness to the lowest setting makes the sound less intense, but it's still audible.
View 2 Replies View RelatedI've noticed on my MacBook Pro (late 2013 with retina, 13", 2,4GHz i5, 256GB SSD, 8GB Ram) that when I run the display on low brightness, there is a high pitch noise coming from the screen (inverter problem)? It seems as it disappears when adjusting to either a high brightness or turning it to zero.

Hey guys, got a little issue here. I have had a MBA since about march of this year. Just recently I on two occasions the computer has all of a sudden had this loud high pitch whine. It has only happened twice and at both times (if I remember the 1st time correctly) I wasn't really doing anything on the computer. Today specifically it was just sitting idle on my desk. Not sure where its coming from maybe speakers? Any idea to what this is? Should I be setting up an appointment to see a Mac Genius?

So if I go into System Preferences/Audio, and I try to play a sound, the high-pitch is heard as the sound plays, and for a second or two after, then it goes away, and is heard again each time I try to play a sound. Same with when I play something thru iTunes or any of my audio apps.
If do the exact same thing playing from a Macbook, I do not have that problem at all, the sound is nice and clear with no high-pitch sound.
I have the speakers plugged in using 1/4 inch jacks to an external sound card (MBox), and this audio card is plugged USB into the Mac.

after i get to the windows loading screen my mac just throws out a consistent high pitched sound and shows a black screen, i can only get into bootcamp windows when i unplug the computer and start it up with the running windows normally option. is this a virus?

I do not need the perfect iMac (I have some gray banding and the 1TB HD grumbling and it is not a big issue to me) I just wanted to see if this high pitch noise is considered a defect and needs to be fixed/replaced or it is more common than not with the iMac.
Just got my new i7 in the mail today after waiting for the refresh for 5 months and it has that stupid high pitched noise that you get when you adjust the brightness. I returned four of these things at the beginning of the year (2 HD failures, 1 power source failure, 1 DOA), one that had the hd failure also had this same high pitched noise.
I love these computers (minus the complete lack of quality control), so I don't want to switch back to PC, but I am at my wits end here. Apple already gave me $150 off this computer for me trouble, but I just don't know if its worth the hassle anymore. I am returning it for sure, but would you ask for more compensation, maybe a ram upgrade or something? I don't like to be the guy who asks for free crap, but the way I see it, they can give me another hundred $, or I can go back to pc and they lose a customer for life.
i was bored and decided to put my ear up to the area right of my air's trackpad, my ear was actually pressed up against the case. oddly enough, i am able to hear a somewhat high pitch beeping sound every 5 seconds. anyone else care to do the same and report back?

Now it's getting more frequent and last longer.
It just stopped when I moved the power saver setting of the video from never to an hour.
I'm not sure where it's coming from yet.
I just purchased a mac pro about 4 months ago and I love it, I have never had a problem with it until today, I went to install a new program on it and it did not even read it, it made a hi pitched sound for a short time then stopped, waited about 10 seconds did the same thing. After a couple times of doing this it would eject the disc, so I figured I would try another disc, I have tried many different discs such as games, cds, programs and nothing has worked.
View 7 Replies View RelatedWhen I turn it on it runs fine for sometimes about a minute (sometimes less) before it just turns itself off! After it turns itself off I'll hit the power button and it emits a high pitch squeal from the machine whilst holding the button. If I then remove the battery from the Machine depending on how long I leave the battery out and put it back in, it will then power up for a short amount of time. Sometimes I can get it to the desktop and open System Profiler for example, other times it gets as far as the Apple grey screen. I've ordered a power adaptor as I didn't get one with the machine but as far as the battery indicator goes, it's on 96% and all four green lights are on the battery indicator on the base. Has anyone heard of any problems like this before?I believe it's running a 500mhz processor and has 512mb of Ram.

I know this happened before in the old Macbook Pros by the look of things when I searched around.Basically there is a noticeable high pitched whine when the screen brightness is either not completely off or max.
View 7 Replies View RelatedEver since the 10.5.7 update I've been getting issues with my macbook, this a new one. I've looked around google for any other similar incidents and there have been but none with a solution so I figured I would ask here. At random times my screen starts making noise, I say my screen because if I dim the brightness to zero it stops, and the brighter I get the higher the pitch, the lower brightness - lower pitch.

So, I just noticed that when I have my MacBook Pro in High Performance mode it emits an high pitched noise when the fans are running around 6.2k RPM and the CPU and GPU is around 63c. The noise follows the speed of fans, and at idle the noise is gone.
I have uploaded a video of it on youtube here: http://www.youtube.com/watch?v=HioRgTNpNRA
My 13" Macbook Pro has started making an odd, high-pitched noise, kinda like one of those 'mosquito' ringtones. It's pretty quiet so I can only hear it at night when the computer is beside my bed on the nightstand. However it's odd in that, it's always present UNLESS I scroll in Firefox. As long as I'm scrolling in Firefox, the sound stops. It seems to be coming from the left side of the computer.

This is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).
So I installed Vista 64 bit on my Macbook Pro (Santa Rosa), I installed most of the drivers I can find, but I cant get the screen brightness buttons to work (F1 and F2)

View 4 Replies View RelatedI bought my first Mac, a C2D MBP 13". I really love the machine. But I'm experiencing this particular issue of having high cpu load of up to 80% while on W7 Professional bootcamp even though I'm not running any graphic intensive programs.
Specs: 2.4Ghz MBP 13" (The recently refreshed model)
Windows 7 Professional 32bit (MSDNA Edition)
Upon successful installation of W7, I inserted the OS X disc inside and the bootcamp drivers installed successfully. So I'm quite sure the drivers are okay. Being a DotA lover, I installed WC3 on my bootcamp. However, I realise that whenenver I'm on windows mode, the machine is very laggy. I even have problem opening a browser when I alt tab out from WC3. Is this normal? Even when idle, the cpu load on the processor jumps from 1% to 47% randomly. Just fluctuates randomly. I'm quite sure my Windows Security Essentials is not doing any scan btw.
I just bought and received a new 21.5'' iMac and love it but the screen is making a high pitched noise, similar to a dog whistle. It's that sound that isn't loud but pierces through your brain. And the brighter the backlight is, the louder is gets. I love this machine but I don't think it should be doing this and it bothers the heck out of me. I called Apple and all they said was to bring it to the Genius Bar.
View 2 Replies View RelatedMy 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 ?
I have a Macbrook Pro, one generation old. In the past week, it started making a high pitched noise from the upper left hand corner, near the keyboard. When I pick the computer up and change the angle, I can eliminate the noise.
Just in the past day I noticed that in addition to this high pitched noise, periodically a much louder, different noise comes from the same area, which again, if I move the computer around, I can minimize the noise.
My guess is that there is something loose in the computer, maybe a fan? Should I bring it to apple? My computer has been running pretty slow lately, could this have anything to do with it?
At times my iMac (27" July 2011) starts making loud fan noise with mouse showing turning rainbow. The only way to stop is forced shutdown by pushing back button for a while. Yesterday I switched to widget screen and saw hard drive fan speed > 4000 rpm without CPU and temps by on the high side.

I wanted to check out Windows 8 so i decided to install it using Bootcamp on my Macbook Pro. I installed it successfuly, along with the Windows Bootcamp drivers, but my Display is VERY dim, the brightness is all the way up to the Mac. I rebooted the Macbook Pro and ran OSX and the brightness is fine, but on windows is very very dim and idk how to fix it.

I don't know if anyone posted this issue before. I can not control screen Brightness on my MBP 13'. I tried my F1 and F2 key and the Nvidia Control Panel, either of them is working. I installed all the drivers from the CD and it can actually show the icon in the center(bottom) of the screen when I hit the F1 or F2 Key. However, the brightness adjust does not work,the screen stay the same.

Question: My Blackbook also has a Bootcamp partition running Windows - is there a way to take that image and migrate it to my MB Air? I'd rather not have to purchase the Superdrive and re-install/setup the Windows OS on my Air....
The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.
