Apple :: 2010 Macbook Pro - An Electrical "buzzing" Sound
May 17, 2010
I just opened my first ever macbook pro from its box. I've noticed immediately that when the unit is tilted in any direction, sideways, back, any direction, an electrical "buzzing" sound will emit from the components under the keyboard.
It sounds very much like the "zzzzzzzzzzzz" sound one hears as they drive by power lines on the side of the road....only toned down quite a bit, obviously. But it's definetly an electrical noise. It's only emitted when I move the computer, but it's already annoying...I hear it every time. And I move/adjust/reposition this laptop around allot.

Sometimes when I am typing on my Mid 2009 macbook white there is a sort of buzzing sound, I have ruled this down to the magnet on the top left of the screen as if i put somthing magnetic near it i can hear the magnet moving slightly, I havent had this issue with my 17" MBP
Is this anything to worry about or is it a common problem? it only happens when the screen is at certain angles

We have all been curious about exactly what is going on under the hood in the new Macbook Pros. It would appear that Apple is indeed underclocking the GPU a bit, at least as reported from GPUz:
I also fired up CPUz and was pleased to the see that the i5 turbo mode appears alive and well, at least in Windows 7:
This is all from the base model, off the shelf 15" Macbook Pro.
I would love to see this thread turn into results from other new machines so download CPUz and GPUz!

While watching a DVD last night in OSX, I noticed a buzzing sound in the right speaker when I was above 70% of the volume.. At half the volume, I don't hear the buzzing noise. It's kind if annoying especially when you're watching long movies. Anyone else have this problem?
Oh yeah, and my CPU temperature went up to 90C. Is watching a DVD that cpu intensive?
I have a feeling this thing is going back..
(15" MacBook Pro)

I just purchased the new 16" F Series. Right out of the box, the unit makes a slight buzzing noise on the right side.
It starts after the unit has booted. It tends to happen when the machine is idle. It's the same if the battery is in or out.

I don't have time for a full review because one of the reasons I jumped so quickly into this new notebook is that I am on a deadline. However there are a few first observations I don't want to forget about, should anyone be interested in a more complete review.
A little history first. I have been a Mac user for the past 20 years. I grew up with them, have been responsible for them in an IT capacity and have made a living generating content from them. I know the platform well. I am however not the type of guy to put all his eggs in one basket and also routinely use Windows, mostly for gaming, and Linux, mostly for serving.
The point is, I make my living around the Mac.
Purchase and Arrival.
I made the decision to buy after 6 hours of spec shopping. I called around to the local Best Buy (you never know until checking) and the closest Apple store, which for me is 120 miles away. Neither had them in stock, but they both at least knew what I was talking about. The Apple store didn't have an ETA, but expected them within the week. That wasn't fast enough for me this time, so I ordered directly from Apple. This was Tuesday night at 5pm. Wednesday at 2:30PM, I took delivery. Nice. The outer packaging was a plain brown box. Inside, the standard Mac packaging with nothing but the notebook, a power adapter, and a simple folder with barebones manuals and the OS DVDs. Good presentation, but not a lot of goodies............

Anyone know where I can get a extra 2010 power adapter for my macbook pro? Most of the ones I have found use the old style connector.

I just got my FW 590 CTO a week ago, and two days after I got it I noticed a buzzing sound coming from the display when the brightness is set to anything other than maximum.

I therefore have felt the need to come back, because I now now have a new problem (well its actually been around for a good few months). This problem is also a buzzing noise, but this time from the speakers and in particular, what sounds like the subwoofer. They randomly start making a crackling/buzzing/distorted static sound at random intervals when listening to music or videos or when using Skype, etc.
I've had this problem for a while and it hasn't bothered me as normally going to 'Acer eAudio Management' and simply swapping to '5.1 Output' and then back to 'Built in Speakers' solved the problem, albeit temporarily. Its been more of an annoyance than anything.
However, on Tuesday (2 days ago) I got my copy of Windows 7 through the post to replace my Vista installation. 7 is fantastic it really is, but since I have installed it all hell has broken lose with my speakers. The buzzing noise is now much more frequent, particualry when simply opening something such as Skype or Windows Media Player, whilst listening to iTunes. Swapping between the '5.1' and 'built in speakers' does stop the buzzing, but now, it comes back almost instantly.....................

Whenever i plug in my headphones into the audio jack i get a buzzing sound that is quite loud and irritating. However, the normal speakers are working fine with no buzzing sound.

I've recently taken delivery of an E7240 with the FHD touch screen option. I am generally quite impressed with the laptop except for one thing, the touch screen buzzes. The sound is similar to a hard disk working, a bit random .. not a constant noise. The sound will immediately stop when I put a finger on the screen though which makes me think it's related to the touch screen itself.
Rebooting etc. makes no difference... shaking the laptop, smacking it (gently) etc. has no affect.....
I realise these laptops are new so perhaps there isn't much experience out there...

have you ever noticed, sometimes, a kind of popping noise coming from macbook speakers (I have the alu one) when you are launching a program that will require the use of speakers? (never happened in itunes, it occurred only when launching quick time videos or some videos / music from the web...)
As said before, it is not always occurring but it happens only sometimes. Is it maybe linked to the osx putting speakers in standby when not needeed for a while (it happens also with electrical supply) ? I read something on the net about a drawback for this behavior inside leopard, but is it really the case?
Moreover, this 'popping noise' intensity is constant whatever the preset volume of the speakers is, and, up to now, I have never heard it with the speakers set off.

I've recently bought an Acer Aspire 6930G and am overall very pleased with it.
However, in the few weeks since i've bought it there has been one concern I have had.
Whenever the laptop is unplugged from the mains, it starts to make a faint buzzing sound. The sound seems to come from the 'tube' near the subwoofer on the back (where the power socket is on one side, and the Kensington Lock is on the other side). The buzzing also only seems to be coming from the right side of the laptop above the number pad.
What is also strange is that i am able to stop the buzzing by tipping the laptop sideways or moving the screen. This seems to indicate that something might be vibrating, but again only when the power cord is unplugged?
Like i say, i don't think its enough to take the laptop back (unless somebody tells me differently), but i am concerned enough to ask on here if anyone with the same or similar laptop has any ideas as to why this might be happening.

what is the easiest way to connect and properly operate a Logitech Z-5500 surround sound system from my new macbook pro 15inch. Do i have to get a new sound card? Or is there some sort of cable that I can buy instead?

I bought a 13 inch macbook pro about a month ago and while enjoying my laptop, I heard a very faint tick sound. after a few days the tick sound become more prominent and after reading few complaints about ticking/clicking sound I am pretty sure this has nothing to do with the motion sensor or fan noise problems.
after few weeks gone by and I found out that if you press the bottom side of the laptop it will make a tick sound (is this normal?) I am not sure if this is causing the ticking problem I've been hearing.

Just a quick question:
has anyone seen what Office 2010 is going to look like? I know that it's suppose to have Outlook, but I haven't been able to find any legible screen shots or credible information on what the new program will contain or how it's different that 2008, etc. I don't know, maybe there's nothing out there except rumors, but I was just curious.

On my (soon to not be my) 1536 I get really loud electrical squeals, kinda like interference that you would get on a phone. And I can usually hear it from across the room.

Microsoft better not be teasing me.
This is probably the biggest reason why I can't stand being a Mac only person. Outlook keeps me alive and isn't as nagging as a wife.
I might just start sacrificing small animals......

I just got a MacBook Pro 13 in and noticed that when I'm using it but then get up to move somewhere else, it makes a clicking sound as I lift up from my lap. Is this normal? Maybe the hard drive is preparing to move or something?

Can anyone tell me if this is a new model or old mid-2007. Cause some one I know thinks they have a newer computer that has this model number/ECM. Is that model # and ECM also for current systems or are they only for older ones?

I recently purchased a new base model 15" Macbook Pro with the firm intention of upgrading the main drive to a SSD. Historically, there has been some issues with a do-it-yourself upgrade to SSD using Mac hardware and I happy to report that I have had no issues, save those caused by myself in the doing the swap.
I decided the best course of action was to use a SSD for my main application and OS drive, and use a standard 2.5" mechanical HD for my files. The downside is, of course, you lose your internal Superdrive. However, as I was contemplating this, I realized that I rarely use my optical drive outside of software installs. It then became an easy choice. Of course, you can always just swap the standard internal drive for a SSD, but space and cost quickly become deciding factors. Keep in mind that if you plan to install Windows 7, you need at least 20GB of space just for it, before any other Windows software. Snow Leopard takes around 8GB and some of the higher end software can take gigabytes on their own (The Final Cut Studio suite alone takes around 50GB).
After a ton of research with some conflicting information I decided on the Crucial M225 128GB SSD. It uses the Indilinx Barefoot controller with 64MB of cache and is price competitive at around $325. The Kingston V-series is cheaper, but uses a modified J-micron controller (meh - sorry J-micron, too much history there). Another choice, and one I nearly made, is a Corsair series drive. Note that apparently the Nova series has some issues with the Macintosh notebook line, so the P series will be your best bet there. Of course, you could go for the gold and choose an Intel based SSD. Most Mac guys seem to have the best luck with these drives, but I decided I like the price/performance of the Crucial better..............

I just got my new MacBook Pro 15" (with auto graphics switching) and was a bit surprised that the discrete graphics card was always on... so I started investigating what apps might be triggering that! As far as I could tell, I wasn't running anything graphics intensive... so it was a surprise to me what I found out
There are a lot more apps causing this than the ones I listed initially... a more complete and up-to-date list can be found at this thread on MacRumors forums.
It's possible to know what graphics card you're currently using by installing GPUInfoMenu or gfxCardStatus, the latter also allows to force switching from discrete to integrated, or vice-versa.

I just wanted people's opinions on how they compare the two model lines, and whether or not they would make the upgrade. The specs of my MBP are:
C2D 2.53 Ghz
500GB 7200RPM HDD
4GB DDR3 1066 MHZ RAM
512MB 9600mGT w/ 9400m Integrated Graphics
Performance wise, I havent been disappointed with the laptop, but one of the main drawbacks I see in the machine is its battery life - Apple has taken strides in improving battery life over 2009-2010, and its kinda annoys me that I'm stuck with the battery I have now.
I commute a lot to/from school, work on the bus/train, and have to use my laptop in places where power outlets are not readily available (some lecture rooms). Realistically, I get about 3-3.5 Hours with screen brightness on minimum, wifi and bluetooth turned of, and doing some basic word processing, as well as reading pdf's.......

All those who have a 2010 MBP and a 3rd party SSD, please try setting up bootcamp and let us know if it works.
Has anyone successfully setup bootcamp on any of the new macbook pros? When I use boot camp assistant, I am able to set up the partitions. However, once I enter the windows 7 install, it doesn't detect any partitions at all (not even my mac partition).
I've tried both 32 and 64 bit versions of Windows 7 (home, prof, and ultimate). The SSD is an Intel X25-V 40GB
UPDATE 1: Swapped the stock HDD back in and bootcamp install seems to work fine. Partitions were immediately recognized by my windows 7 ultimate 64-bit. Could Apple have blocked support for 3rd party SSDs somehow with these 2010 MBPs?

To start I should remind everyone that i'm not a mac user. I have never owned a mac or used OSX properly before today. As such, my opinions should be taken as coming from someone who has much knowledge and experience as far as PC's are concerned, but who is a total mac n00b.
First Impressions
When I first walked over to the Macbooks I was quite taken aback. The build quality is out of this world. In fact, I immediately walked over to the latest PC laptops to compare and immediately thought "manufacturing FAIL". Really, the Macbooks are italian sports cars, and PC's are 30 year old farm tractors to use the typical "car analogy".
The Macbook
I really only had any interest in the Macbook when I first went to the Apple stand, but came away with the intention of buying a MacBook Pro. Let me explain:
The MacBook's build quality is awesome. It's solid, no creaking plastic or flexable build, completely and utterly solid. Awesome.............
