MacBook :: Mag-Safe Whistling Too Much Noise
Mar 13, 2009
2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe.I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something.

Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.

I just received my very first iMac two days ago & just noticed this horrendous whistling noise that reminds me of leaving a really loud concert. It coordinates with the display's brightness apparently (I looked it up before hand) & stops whistling at max brightness & min brightness. Anything in between = whistling.
How should I address this problem? Should I just go to the Apple store & have them replace my iMac? :/

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?

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?

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.

Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:
It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.
I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.
This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.
I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was
in the other room.Is my PISMO dying?

I just got my macbook pro yesterday and ran it all yesterday not hearing anything. Today when I woke it from sleep I could clearly hear the fan or hard drive going. I was in a quiet room and it's quite annoying.
istat says its at 2000 rpm so thats when I started thinking it may be the hard disk. It does pulse every now and then but thats even while it's just sitting idle.
I guess I could live with it but its just annoying. Anyone else having this?

Just upgraded my MBP from one of the first unibodys. The new computer is great, but the power cord? Surely that was one giant leap backwards? Yeah it looks cool, but I have nearly destroyed my new MBP many times - that old panicy, heart in mouth feeling when you trip over the power cord and turn round to see you computer sliding towards the edge of the table is back! With the cord parallel to the body rather than perpendicular it doesn't seem to have the leverage to pop out easy any more. Admittedly I am clumsier than most, but then thats why I loved the old magsafe so much. It makes me wornder, am I just using it wrong or does anybody else wish for simpler times?

Is it possible and safe to use the MBP 15 without the battery? I know you can a Windows laptop. I have the MBP 13 which I use for portability. The 15 in just stay stationary. All I am doing is just cycling the battery over and over and using up it's life. I didn't want to try it without advice.

I have a 13" MacBook Pro, and I have refused to upgrade to EFI 1.7 (even though updater keeps telling me to upgrade) because I had heard of problems with that firmware and SSDs.

I ask because the voltage is higher (16.5v vs 14.5v). I would assume the 60watt would charge faster, but not sure if the voltage increase will do damage.

I noticed that many people who had freezing issues with their i5/i7 MBP, had gfxCardStatus installed, hence why I never installed it. Can anyone confirm that it's safe to install it and that all freezing issues are gone? ( My MPB never frozen once, but i'm afraid freezing issues will appear if I install this App

I just bought a used macbook pro, 15" 2.53GHz Core 2 Duo, and I have previously been using a 13" macbook, on which I recently upgraded the hard drive. I'd like to pop that hard drive in my new MBP, since it is bigger, and has all my data on it, but I'm not sure if this is a safe thing to do - if there are hardware specific aspects of the OSX environment that will be unhappy in a new machine. I'm running OSX 10.6.4..

I have a 15" 2008 uMBP and it seems like the screen is very hard, sort of like my iPod Touch screen, so I'm guessing fingerprints won't harm it in the least. Do you guys touch it, or allow people to touch it?

I've had my Macbook for 3 years, each year I have to buy a new mag safe power adapter. I'm not some extreme user, the connection between the coupling and the cord is incredibly poorly designed. I had a PowerPC powerbook 12" before and never had a failure. My computer (and mag safe) goes to the lab and back home and that's it. Do these plugs have a warranty? I'm on my third one and it is starting to fail the same way (where the cord meets the magnetic plug at the computer). At least time it's less than a year old, if there is a warranty.
