MacBook Air :: Rev B, Lines, Flickering, Buzzing - How To Avoid It
Jan 22, 2009
I just purchased the Macbook Air rev 2 120gb HD model. I it has the problems with the lines on the screen. It flickers on the one test image from the forums, but does not appear to flicker during normal usage. Also, it has a sort of CPU buzzing comming from the left side of the keyboard. It gets worse then I move the trackpad.
I was thinking of calling support on this, but I don't want to end up getting the same screen with the same problems. I was wondering if anyone has gotten any of this fixed. Is there some way that I can direct support so that they put in the correct model of screen.
Let me preface this by saying I am probably taking this to the Apple Store about an hour away from where I live tomorrow. For A while my MacBook Pro 13" has been making a loud spinning/grinding noise on occasion. Normally, I'd just shut down, boot up, and it would be fixed. Well, yesterday, that didn't work. After being told by the support guy that my free phone support expired 14 days ago (Mac bought in June), he said he'd do what he could to help. I told him about the noise and held the phone up to it (it is coming from the right of the trackpad). He said he had never heard that before and said to take it in to the Apple Store. I've found an Apple Support article, but it doesn't shed a lot of light on the situation.
The screen on my Macbook Air just recently started to periodically display flickering lines. They are multicolored and stretch across the entire screen. Hardware test was ok, and console not reported any issues. MBA is "late 2010". Warranty ended January!
I have a new 17" uMBP that I've owned for just a few days. I noticed yesterday that while I watching a video that i had strange green/red lines (horizontal) appear across the screen and flash/flicker. I freaked out and closed the lid, putting the unit into sleep, and opened it again and it all stopped. Today, I was using it again as usual, on firefox/etc. when it started happening again. Horizontal lines across the screen, the entire display flickering and screwing up and finally going black. I don't know what's going on, but I know this definitely isn't supposed to happen. I took a screenshot during the flickering/lines/etc but the screenshot came out perfectly fine unfortunately. I'll try and get it on camera next time.
I have all software updates installed. I tried resetting PRAM. The flickering I'm talking about isn't minor, it's actually absolutely horrendous and the computer is completely unusable when it's going on. It ultimately leads to a black screen. Anyway, this is all on the 9400, and I have no idea what's going on but I definitely know this isn't supposed to happen. UPDATE: I booted into Windows via bootcamp and it STILL happens. I also connected it to an external display(which works perfect), which leads me to believe that it's 100% a hardware issue. I'm taking it back to the apple store, enough said. This is my first Mac and I can say I'm definitely not happy to be having such issues with a $2500 machine.
I was sitting with my MacBook Pro, when out of no where, purple vertical lines began flickering on the screen. I tried getting them to stop, then eventually just shut down my laptop. When I went to power it up again, it first popped up with the white apple screen and chime, then a gray screen dropped down with the message "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button.".
I tried the Power button option first, but the computer does not come back on. When I press the Power button again, it does the same thing all over again. I do not know where the "Restart button" is, so I haven tried that. I have also tried pulling the battery and restarting, restarting in safe mode by holding the shift key at start up, and trying control-r and control-s functions. None of which worked.
My brother's ibook (14", 1.33 Ghz, 1.25 GB RAM, 10.3.9) recently developed a problem: when he would open it, the screen would show fuzzy lines for a few seconds before "stabilizing." He tried to live with it, but it got progressively worse. Now, the lines never disappear, and the screen flickers as well.
My Macbook pro's display has started playing up. Having green flickering lines which come and go randomly, especially on images with a lot of black. Right now, the lines just disappeared as soon as I connected to mains, to start recharging the laptop. I'm using OS X 10.7.4 with NVIDIA GeForce 9400M.
Well, I have a late 2008 13" Macbook Aluminum, (I've had it since Christmas of 2008) and just yesterday, I noticed a weird buzzing-like sound coming from the inside of it. There's also a faint vibrating feel to it. I felt around, and the vibrating feels like it's coming from under the middle of the keyboard more severely. The buzzing occasionally sounds like it's getting faster, and then slower, faster, slower, etc.
I noticed that when I move my MacBook Air when the fan is running, it makes a slight buzzing/grinding sound. Is this just air hitting the fan at a different angle or is it a bigger problem that needs to be fixed ASAP?
I purchased a Macbook Air from Amazon. The display is excellent but i've been having this constant buzzing noise going. It's very irritating and I'm not sure what is causing it. I definitely didnt hear this noise in my rev A Macbook Air or in Macbook air sin the Apple store.
I was just downstairs in my basement using my macbook and I decided to come upstairs and when I got up here I noticed that my fan is making a weird buzzing noise. I can tell it is my fan because when I make the fans spin faster in smcfancontrol the noise gets louder. Could this be something that is in the fan or could this be a more serious problem? I can take the back case off and check but I just wanted to know if this could be a serious problem with the fan. Is there any chance I could have bent something by carrying it wrong?
About 5 mins ago i rebooted my Mac, and in the boot process something started to buzz horibly. I was in a dark room, so it was very scary for me and very late too... Being scared i pushed CTRL+OPTION+SHIFT+POWER so it shut down imeaditly.
I powered it on, no buzzing. But OS X did not boot at all. Just stood there. Now I'm booting of the recovery DVDto disable my EFI pass, so i can boot verbose.
I have had my MBA for almost a week, and I've had no issues so far. Until now. This is the case: The fan operates as it should. It stays on 2500 rpm at light use, and increases with heavier use. At 2500 rpm I was not able to hear it without putting my ear next to the keyboard. That was yesterday. Today the fan produces a new noise. It isn't very loud, but clearly audible at 2500 rpm in a quiet environment. It's a low, constant, buzzing kind of noise. It also increases with fan speed.
I purchased my Macbook in August 2007 and have no problems until Christmas this year.
It started buzzing and I wasn't sure what it was, until a week later I got a folder with a question mark at log-in, from what I understand my hard-drive died. I replaced the hard-drive myself within a few minutes, very easy and no problems, and it runs perfectly.
It's been two weeks and it's already buzzing again. I take very good care of my Macbook but I do transport it from class and back everyday.
My whitebook is making a buzzing sound that is coming from under the F4 and F5 keys, it can be heard a little with no background noise but when i put my ear close i can hear it much clearer. Does anyone elses macbook do this or does anybody have any idea what it is and should i take it to the apple store?
I just bought a refurb MBP 2.4... I'm noticing that at high volumes my speakers are crackling/buzzing/distorting/whatever you call it. I'm planning on taking it in tomorrow... Anyone have any experience with this?
Over the past few months or so, I've been noticing a sound, much like a buzzing, coming from the left speaker area of my computer. It seems to be near the area where I plug in the charger. The sound is not terribly loud, but when it's quiet in my surroundings, it becomes quite evident. I'm not talking about an audio-related issue, but I am just unsure as to what may be causing the sounds and whether or not I should be worried.
Yesterday I started up my MacBook Pro that I've only had for about 9 months. I immediately noticed that there was a barely audible buzzing / humming sound coming the inside of the laptop, most likely in the fans. I don't know how long this has been going on, and I really don't know the cause of it. So is this something I should be worried about (the sound is barely audible)? Or is this something that happens after prolonged use of the laptop?Â
My MacBook charger has always sparked a little when I plug it in (not every time, but often), which I've read is normal, but lately, I've also been getting a pretty loud buzzing sound both from the block and from the outlet. I have taken the disconnectable cord off the block, made sure all the connections looked clean, then made sure it was reconnected snugly, but I still have the problem. I've been having to unplug and replug from the socket several times to get the buzzing to stop (if it makes a difference, I always plug into the wall before I plug into the laptop, so the charger is plugged into nothing when I plug it into the wall. The sound starts as soon as the LED turns orange, and continues intermittantly, especially if I move the mouse. The block, itself, doesn't seem any hotter than normal). The cord is undamaged, but the prongs are a little scored up at the tips. It seems to happen more readily when the charge is below 65%. I did have water damage occur several years ago (I got lucky: The only problem I had was a messed up battery), but have had no other problems with my MacBook. I've only plugged it into an alternate outlet when the charge is above the 65% mark, and have gotten no noise from the other outlet, but can't say for sure if it's because it's a different outlet or if it's because my charge is above 65%.Â
I am planning on bringing it in to see if I can get my cracked palm rest repaired (if it's covered despite being out of warranty, which I have read/been told by a fellow MacBook owner that it is) and to see about upgrading to Lion, and I plan to have them check the cord and battery (Which no longer warns when it wants to be plugged in and is at 349 cycles), but I was wondering if this is something I should be concerned about, and to see if anyone else has had an issue with it.
Info: MacBook (13-inch Late 2007), Mac OS X (10.5.8)
I heard it was normal for Mac's to overheat, but mine gets hot. I don't know if it is because I'm not used to it, but it's been on my lap for 30 mins. (on as well), and it has already burned my leg.
I've had my Macbook Air 1.8GHz SSD since basically the day it was announced and aside from iChat video lag and YouTube (which has only happened lately), it's been almost perfect. One of the things I particularly loved about it was how silent it was, but as of Saturday, that suddenly changed. It now makings a constant (as in, never stops as long as the Air is on) noise which sounds like a harddrive being accessed; a kind of buzzing/whirring noise. It's not particularly loud, and once about 2ft away you can no longer hear it, but it is concerning that it would suddenly start.
Ever 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.
i got istat like everybody told me i should get. so now im just wondering what should be my computer temp, im not doing heavy, just internet, music, i have it set on celsius.. so where should i look on istat and whats the temp i should see to make sure my computer its not overheating
So I have had the Logitech Z-5500's since September and have never had this problem until just now, but for those of you familiar with the system you'll know what I mean by the Control Module(CM), if not it's the thing with the volume knob and screen. It is what actually contains the circuitry for the digital to analog conversion and the DTS/Dolby surround sound hardware.
Anyways, recently my WiFi connection has been horrible if not non-existent, with either being unable to connect to my network or if I am lucky enough to connect I can't load anything. Well I thought it was the 12 South BookArc that I have for my MBP because when I lifted my MBP out of it my webpage would instantly load. But that couldn't have been it because I have been using it since Christmas with no problems until now. Then one day I accidentally moved the CM away from my MBP while the net wouldn't load and it instantly loaded.
