When the Macbook Pro is charging, I can feel a little electricity in my fingertips. Unfotunately, I don't have a three prong outlet, just two. Either way, I think this was not supposed to be.

..by the power unit at the back of the machine - where the power cord goes in.
I happened to be switching out displays at the back of my MP today. Could hear the fan at the lower back portion of the machine (as normal). but this time could also hear a very slight electrical hum just by the power unit -- is this normal (the hum) does yours have this hum?
I never heard it before. guess my head was never that close to it when the MP was on the floor. but since i moved it to the top of the desk my head is closer to it when I switch out the DVI ports
Trying not to be obsessive. I'll run before the white coats turn up by the front door
When the computer is sleeping or if I turn it off but the plug remains in the electrical socket, when I get very close to the machine I hear a slight crackling noise, as if the internal adaptor is making a slight noise. I don't hear it from any normal distance, and other than the buzzing phenomenon when brightness is below 50%, no other symptom. Is this normal for this model. I believe that the external adaptor for the 30" ACD made a louder but similar noise as well unless unpluged.

I've always had a minor issue with my various Macbook Pro's over the years. But with my new MBA and the sudden drop in temps here in Chicago, my MBA is off the charts. I have started my winter routine of touching something else to discharge first before touching my MBA. Otherwise, I'll arc a spark every single time.

View 6 Replies View RelatedSo I'm at a client tooling around with my late 2008 Aluminum MacBook. Carpet. Cold, dry weather. Are you getting scared yet? Go to pick it up off a table and zt! Shocked the hell outa myself and apparently my MacBook. I grabbed it on the right hand side and the static charge must have discharged through the slot loading cd rom drive. Now it won't charge. Battery and Mag Safe brick tested fine at the Apple store. They're going to swap out the Mag Safe port for $110 first and then the flat rate repair for around $380 if needed. Note to all Aluminum MacBook/Pro owners. Ground yourself, or plug in the grounded PSU brick.
View 5 Replies View RelatedHas any one else experienced the random, but rather persistent electrical sounding snap or click that occurs while navigating the computer mostly with the touchpad. It is not the hardisk (been replaced to no avail). One person on apple forums suggested that all Macbook Pros make a snapping sound because the soundcard is either powering up out of sleep or powering down. It occurs sometimes more frequently, others not at all. Apple has offered to replace the computer with a new one, but if this is an endemic problem with just about all of them, I'd rather keep the one I have. The snapping or clicking isn't resounding, but can be rather irritating in a quiet room. At first I thought it was a short circuit sound snapping but was convinced otherwise later.

View 9 Replies View RelatedMy Macbook pro is not charging. If I move the cord (specially at the Macbook charging port) it charges. But again if the cord is slightly disturbed then it doesn't charge. The problem got worse as my Mac randomly shuts down (especially when I remove the mag at the Macbook charging port). I dono what to do. Apple care (Genius) is far from my place.There is no visible physical damage on my mag charger. Could anyone suggest what I should do? I checked the battery status in system profiler and it says NORMAL. The details are as follows:Â

I just got a new 13" MBP. I noticed that there is slight vibration on the right palm rest. I know that the hard disk is located under there but is this normal? Do any of you 13" MBP owners with stock 5400rpm drive feel the subtle vibration in your MBPs?

View 8 Replies View RelatedI am a proud owner of an Apple Macbook Pro 15 inch since Feb 2009. I am a converted user from PC to MAC and preach the benefits of Apple OS X et al to colleagues, friends and family. This morning I noticed some slight peeling on the bottom right side (near trackpad) of my Macbook Pro. At first I did not realise what it was, I thought it might be some surface marking / dust. I wiped the area with a dry cloth at which point a small part of the surface came away. Here is a link showing images that I have just taken. Need some constructive advice from the forum on what to do?
View 24 Replies View RelatedI took the plunge and got a MBP 13 (5,5) in October. Its all going well except for the same problem that recurs.
The problem is that when plugged in via magsafe i recieve a mild tingling throughout the shell. This first happened a week after I got it but I solved it by using the long lead instead of the smaller plug. But now even the longer lead which is supposed to remove the issue still gives me the same vibration/electric shock feeling. Its NOT minor, I feel it when its plugged in and it hurts! I get a headache when it does this.
Everything is perfect except a white back light bleeding in a form of a line from above 3-4 inches from the bottom of the screen. Its only visible in solid black background.

View 7 Replies View RelatedI bought this computer (Macbook Aluminum 2.4 GHz - currently running Snow Leopard) last October - my warranty ends Oct. 16th. Anyways, I put a disc in the drive earlier today, and the computer took it right away. That was unusual because half the time it doesn't wanna take the disc (someone at the genius bar assured me all of these Aluminum Macbooks are this way). So continuing with my story, I took the disc out when I was done and I heard slight clicking noises coming from the side where you put discs in. I closed the computer because I thought it would stop it, reopened it, and it was still doing it. So then I restarted it, and I didn't hear it. Now I'm hearing it every so often.
View 4 Replies View RelatedI just got my first mac and its a MacBook Pro 15" i7 HR-AG and wanted to protect it and so I purchased a Zagg Invisishield for it. I also paid $20 for the installation ontop of the purchase to get it professionally installed...as I was looking into the details I noticed that the pieces are not properly cut out for the MBP 15" and are off leaving the edges unprotected from scratches. Disappointing because the edges will be most prone to scratches. Here are some pictures of my New MBP and Zagg Invisishield installed....
Also Zagg Invisishield owners is your cut out a little off too or did I end up with a bad one?
Today I just noticed that my MBP makes a very slight sound once in a while. I'm thinking it's just the hard drive working slightly harder. Is this normal?
View 14 Replies View RelatedMy mouse wire (or cable, or whatever..) is kind of messed up with the wire showing on the connection to the mouse and basically in the middle of the wire towards the USB connection to the CPU. It's the Apple mouse.. will I get an electric shock if I touch it while it's on? It's kind of sounds funny that I'd touch it but you know ..
I have electrical tape I don't know if that's necessary.
I have a 28" inch display attached to newest version of Air. Works ok except when I have a full screen on plain dark grey background, then I see a waviness or flickering effect. Like the dark grey in Iphoto background. Other than this, the other colors seems ok. Pictures are fine, even when dark. Maybe there's a slight flickering with dark blue. Any explanations for this.
using mini display port to dvi. Tried with a friends dual link display, was a little different, but still unstable looking in dark grey when it fills the screen.
Could it be just what it takes to make this color, or the Hertz, which is 60. Other than this, no problem with the screen.
I received my 15" MacBook Pro 3 days ago and tonight I happened to notice a slight click noise when i open or close the lid. It sounds like it is coming from the hinge area.
View 5 Replies View RelatedI'm starting to feel vibrations and some kind of "staticky" sound when I play any videos or music near or at loudest volume. Could it be possibly due to a loose screw? I noticed that on the bottom of my notebook, one screw seems to be slightly looser than the others.

I just got my 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 don't know if this is something to be worried about but I notice that when the tip of the display port cord ( from the ACD ) touches the metal frame of my MacBook Pro there is a tiny blue arch of electricity visible. Well, I just bumped that cord into the frame of the MBP and as soon as that happened the computer completely shut off, it just went to a black screen and turned back on when I connected it via AC outlet. When the computer started back up the clock was messed up ( 2008 date ) and it had forgotten all of my WIFI passwords.
I was just wondering why this happens?

I have a MacBook Pro 15" - Model A1226 (Santa Rosa, circa 2007). I need to replace my right fan. AppleCare just expired (of course). But replacing the fan should be pretty easy, I think.
The only question is about the tape securing the fan to the heatsink. On the old fan it looks like electrical tape, but on the "sticky" side, it looks like there is a bit of copper (?) in the middle.
So my assumption is that regular old electrical tape is not appropriate, but some special kind of electrical tape. What type of tape is that?
My 2.33gh intel core 2 is acting erratic. The finder quits, stalls and freezes...it turns off and then reappears. Programs fail. adobe will not run. It was on during the huge electrical storm last weekend. It started acting like this after. It was on a surge protector, but those are not 100%.
I can get a ways into backing up files. I am attempting to install Lion, but I did not journal the partition. And It looks like I have to clean install and erase the HD. If power surge did damage, software will not work. Does the finder issue look like electrical damage?

I have a mid-2009 13" Macbook Pro with 8GB RAM. I have the odd situation of the power indicator on top right of screen showing that the power adapter is plugged in, but the percentage indicator stating that the laptop is "not charging." I have been working on the computer for several hours and the laptop has only charged to about 27 percent according to the battery health application that is runningI have. It says the battery has gone through 281 cycles and is 2.4 years old. It suggests the battery should still charge to 92 percent of its potential. The battery is warm as is the power adapter cube, so something is happening. The little light on the end of the power cord is green but only two of the little green dots light up on the left edge of the computer. Â
