MacBook Pro :: Beeps And Horizontal Bars In Display Of 201113"
Mar 13, 2012
I'm running 8GB RAM as I have been for several months now. I typically run several apps at a time for days at a time rarely dipping below 1GB available. When I do I use the Free Memory app to free up RAM.
Minutes ago I left my MBP for a couple minutes to do something across the room. It began making single short beeps spaced a couple seconds apart. When I ran over to check out what was going on I noticed the display had 2-3 vertical stripes through it each containing dozens of horizontal colored bars. The beeps continued without stopping. The display was unusable for the duration. I could not tell if th keyboard or trackpad were responding so I chose ot reboot.
After reboot it seemed fine and reopened all of the apps that had been running previously. Or is this a sign of specific hardware beginning to fail?
Have had this macbook for just over a week, purchased off original owner who bought in Feb this year with Applecare warranty. Upgraded ram immediately to a G.Skill 4Gb kit. 4 days ago, computer randomly froze with horizontal coloured bar. Called Apple next day, the guy there told me that sometimes this happens, and that I should only be worried if this occurs ago. 4 days later, we are at this present scenario: In the last hour or so, has crashed 3 times. Programs running in common were iTunes and Safari.
I'm totally freaking out right now, I have a MBP 17" 2007 model with 2.66 GhZ Core 2 Duo processor, 4GB RAM and GeForce 8600GT graphics. I was working on Adobe Acrobat when it crashed for some reason. I restarted the computer and clicked on "Send to Apple" (error report) but it suddenly hanged on this screen with bars all over my display
I have a 19-inch Envision EN9410e LCD flat panel monitor. Right now I did a mirror display setup. The native resolution of this monitor is 1280 x 1024. When I went to System Preferences to change it to that resolution my LCD monitor shows the Snow Leopard desktop but it's in the middle of two black bars. I had to revert to 1024 x 768 resolution to not have the black bars show. Is there a way I can change it to the native resolution and not have the black bars on the top and bottom show up on the screen?
I have a white line in the display where I also have my dock. So it's not always on the same Display. You can see a few pictures attached that show you that this line is some kind of weird. Windows that are always in the front like "About my Mac" are over this line and if I open all windows of one program I get three of those lines.
The lines are here since I updated my MacBook to the newest firmware.
My new MacBook Pro has started to randomly totally lock up. The display will fill up with horizontal flashing lines, the keyboard freezes and then it will start beeping 3 long beeps continuously. the only way to stop this is to hold down the power button untill it shuts down. Restarting it can take quite a while because it just comes up with a black screen and continues to beep 3 times. Eventually it will start normally and work for a while till this all repeats itself again. It does this randomly, sometimes it will work correctly for days, sometimes 5 minutes. This is my first Mac and I`m not sure if I made the right move now.....
i recently bought a 13"retina display macbook pro. It is so disappointing. There is a horizontal line that appears on the screen and disappears. This was for the third time i had to face the same issue. When i explain to the staff at the apple store they say that they have not come across such issue, for which i showed a proof from the other part of the world.
my MacBook pro display that there are frequently horizontal grey lines going across my screen. I've noticed it mostly when the display color should be grey or white, but that's not always the case. It occurs mostly in my Google search bar using Firefox, and also occurs heavily on Facebook in the comments/reply section of a post. Outside of the browser I've also seen it when looking through some personal photos, especially of the sky, the lines will seem to sort of outline different contrasts in white or light tones, kind of like the Magic Wand tool would do in Photoshop. The lines do flicker and change when scrolling.I attempted to snap a photo with my iPhone the best I could.
My specs:
-13" Macbook Pro (2009) -Intel Core 2 Duo 2.26 GHz -NVIDIA GeForce 9400M -Resolution: 1280x800, 32-bit Color
So I had a recently purchased 17" BTO with the 7200RPM drive that worked great, but with one issue - the display would have horizontal scan lines and black out occasionally. So I called up Apple and eventually managed to get a cross-ship set up(they let me hold on to my current unit, charge my credit card and send me a second brand new 17" unit as a replacement,and then refund me for the second 17" after I send back the defective unit).
Anyway, the replacement unit looks great, but with one issue - there's a very small light dent on the bottom panel(maybe about the size of a dime). I was annoyed but don't think this is worth having to exchange, since I could probably just unscrew the panel and pop it back into place.
However, what really got to me was the fact that my replacement unit was slightly louder than my original - my original is so silent that I can't even tell it's on. However, with my replacement unit, I can hear the hard drive spinning, which is slightly annoying.
Anyway, I proceeded to restore from a time machine backup and test my replacement unit when I noticed that it would occasionally get the hard drive click + beep + freeze issue that many others who have the 7200 RPM drive seem to be facing. It's extremely annoying, and more importantly I miss the complete silence of my older unit.
My question is, while I'm still in possession of both units(which both have the exact same specs, same 7200 RPM drive, etc.), should I simply just open both up and take the silent(good) hard drive from my old unit and put it into my new one?
The click+beep freeze issue is really pissing me off, and my old unit didn't suffer from it - it's just this replacement one(doesn't make any sense).Anyway, would notice if I switched the hard drive? Would I get screwed somehow? Do they keep track of the hard drive serials or something?
I really don't want to go through the pain of sending this back, especially considering that a LOT of people are suffering from this issue, and I don't want to end up with another defective drive. I'm sick and tired of games and just want a computer that WORKS.
when I woke my pbook up the screen had a horizontal line across it, and below that there is doubling and tripling of the screen image going on. Rebooting didn't accomplish anything and when I take a screenshot it doesn't show up there. I have a 12" Powerbook G4, running os 10.4.11.
I have a 2007 Mac Pro 1,1 with attached 24" apple display and utilizing 5 GB Ram and maxed out on internal hard drives. It's been a flawless workhorse and I mostly tax it with Photoshop which it does well. Well, yesterday, I was viewing a small video on my Mac when this issue occurred. Suddenly I saw these squiggly looking horizontal lines on my display. Then I saw a spinning beach ball. I had to shut down.
I double checked my display cables in case any were loose - no issues. Restarted without issue. Went back to work on my computer - no issues doing ordinary tasks such as opening windows, moving files and surfing the internet. Went back into Photoshop and resized several dozen images without issue. Then, this happened again... restarted. Zapped PRAM just in case. Fired up Tech Tool Deluxe (older version 3.1.3) and it found NO problems, I passed all tests.
Then... out of nowhere it crashed again, third time... I don't recall what I was doing to be honest. I shut down my Mac last night and this morning have spent an hour on and so far, so good. However, I'm not taxing it by doing anything intense. I need to use Photoshop for a project I'm working on so I will do that soon and see if this issue repeats.
I've tried searching the forums but can't find anything conclusive to my specific issue. What else should I do? What else should I check? Is this hardware or a software issue? I have temperature monitor installed - should I be looking at specific temperature increases and if so, where?
GPU going bad on logic board? This is a really close up image taken with my iphone, obviously the lines aren't this large.

Info: MacBook Pro with Retina display, OS X Mavericks (10.9.4)
I have a MacBook Pro 15" and my father has 17", both 2007 model.
I bought a new Samsung XL2370 external monitor (1920 x 1080) for my notebook. When I connect it to the 17" model, it works fine and gives me the full picture.
However, when I connect it to my 15" MBP, even at 1920 x 1080, the display gets cropped on two sides with black bars.
If I change the resolution to 1680 x 1050, then the whole screen is filled. But if I put it to 1920 x 1080, this happens.
I have an EMac G4 that has a number of problems, It is a 1.25gz. Sometimes it will boot to a blue, blank screen, on holding down the alt key I see the boot drive and I can start up (10.4os) but will go to the blue screen again. When it does start up properly, which it does for no apparent reason, there are little dash shaped spots on the screen and a flashing horizontal flicker. I ran fsck and disk utility and installed a fresh version of 10.4 to no avail. I do not have the original disks so cannot run hardware test. The computer falls under the Apple emac screen repair but they will not accept it because it is out of the three year time limit, very frustrating and unfair.
My iMac boots up (OSX 10.4) and when the desktop is about to appear the little spinning wheel start to get "fuzzy" (yes only the wheel), then when it's time for the desktop to appear the entire screen goes blue with horizontal lines across it. I can see nothing on the screen at all except that mess.
Weird thing is, if I boot using the install disc, everything is fine. he display never screws up. So I am guessing some file or something is corrupted in OSX?
I was going to do a restore, but since there have been some updates since I got it, I am worried about that whole process and not being able to get to my pictures and what not on the HD. The procedure where I can archive the current OS and reinstall the original seems like my next step.
I have a 2.8GHz Intel Core 2 Duo 24 inch iMac in may-june 2008. I bought it because I wanted to avoid the 20 inch display problems. Somehow I feel I ended up with the wrong side of the deal. Check the snapshot please: The picture was taken using my iPhone so it's not exacty Cannon quality, but still, it describes my problem in 1000 words
What would you do in my place. Would you risk getting another one, maybe a crappier one? It is ludicrous that you take part in a russian lottery when buying a fairly expensive product like a Mac.
So I just got my MacBook, mainly for school. The wireless service at my school requires a username and password so I went to the place and paid the 10 bucks for it. They said when you open up "Internet Explorer" (I chuckled) that a window would come up asking for your permission to continue or whatever and then you have to put in your username and password. When I join the network in Airport it says I have full bars however when I open up Safari or Firfox it instantly says that I'm not connected. What can I do so that it will ask me for my username and password so I can actually use the internet? I have gotten to the page where it asks me for my username and password before but I hadn't yet set up an account so I just exited out. Now I can't even get to that page! Hopefully there are some people out there that use the same type of wireless service at their college...
just got my MBP 2.8 and its fantastic..BUT it sounds like there are more sound in the right speakers than in the left speakers. also it sounds like the left speakers is more discant. how can that be? i'v checked the systemsettings
Could somebody tell me what that app is that I see running in many people's finder bars? It has the red and green bars on it running vertically. I can't figure out what it is. I've tried searching, mroogle, etc but when you don't know the name of it, it's pretty tough to find.
I have had my Laptop for over 3 years now and with really no significant problems. A couple of days ago though, my laptop display got 3 vertical black/white/black bars on the right third of the screen and I am just curious if it is dying. I am connected to an external display and it's been awhile like this, but it makes it impossible to use as a laptop anymore.
When my air returns from sleep I go from full airport connection to 2 bars and websites load so slowly, prior to sleep everything is fine and so is resetting the air and everything returns to normal.
I have the 2.4ghz aluminum macbook, late '08. I go to a community college that is pretty large, compared to community colleges. I have full bars most of the time at school but about 50% of the time there is no connection. On mozilla i get an error to contact the server administrator and i just get a no network on safari. I installed windows 7 and there is also full bars but no connection. My friends, who have PCs, connect fine. There s a dell netbook and a 50lbs Toshiba laptop.
