MacBook Pro :: 2011 15" Occasionally Freezes And Beeps Loudly In Groups Of Three
Jun 9, 2012
This problem typically occured when I was doing something particularly strenuous, but I just recently had it happen while browsing the internet. The computer will suddenly freeze and start beeping loudly in groups of three with an LED on the front flashing in sync with the sound. I am running Snow leopar if that has any bearing on this problem. What exactly is causing this?

MacBook Pro (15-inch Early 2011), Mac OS X (10.6.8)

I have a brand new Macbook Pro (Christmas 2011), and today it was installing updates. It stated that it needed to restart to complete the updates, so I confirmed it. It shut down fine, but then didn't start up again on it's own. I waited for about an hour before manually starting the computer by pressing the power button. It did the opening chime and then the logo screen came up, but then it started a series of beeps along with blinking battery light (it is fully charged). It froze on the logo screen and continued to beep for a half an hour before I forced it to shut down (control+command+power button).
I tried restarting it in safe mode (holding the shift button down during startup), but it only resulted in the computer freezing on the logo screen for about five minutes before shutting itself off (no beeping or light that time, though). I went through my instruction manual as well as online searches to see if maybe I could somehow restore the computer to factory settings. I can get it to get into the Disk Utility section (holding down the option button during startup), but I'm absolutely terrified of erasing something I shouldn't.

So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3. Â
The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.
I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests.Â
At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower). Â

I just had my iMac hard drive replaced due to some corruption found on it. I had it into the genius bar because of this same issue - beeping three beeps and then locking up requiring a manual shut down. Just got it back this week. Happened again after about 6 days.Running presentation software my system was purchased optimally to run.

Every few weeks my iMac will suddenly freeze, the screen going black or white or pink etc. The only way I can get the computer back is to hold down the power button to force a shutdown. Then after a restart everything is OK for a few more weeks. Usually it occurs when I am on the internet. I click on something and suddenly the computer is frozen. I am on OS X 10.6.8 and usually use Safari. Ironically when I opened this forum 5 minutes ago there was a similar sounding problem at the top of the list!

So, for the last two months my iMac (27", 2,7 GHz, mid 2011, 12 GB RAM, AMD Raderon HD 6770M 512MB, running OSX Lion 10.7.3) has started to freeze during games and from time to time during youtube videos or VLC. A reboot is required, but the problem usually comes back within 5 minutes or so.Â
The game I play is usually StarCraft 2, which worked fine for about 6 months before the freezes started. Most of the time the computer just freezes but sometimes the right side of the screen is moved to the left side and the left to the right. Then the freeze occurs, the screen turns grey with small vertical stripes on it. Graphics hardware problem?Â
No swaps of the screen occurs during the freezes when watching video but everything else is pretty much the same. After a few freezes the iMac refuses to reboot for a couple of hours.Â

Recently I have woken up during the night because my Macbook has randomly 'awoken' causing my two external hard drives to spin up and its internal system fan to start blowing loudly. This is weird for a start. What's weirder is that it doesn't fully wake up when it does this, or at least my external display doesn't come on, it just sits there in this half awake/half asleep state with the fan blowing a gale. If it's doing something weird like waking on LAN or Bluetooth or one of my iDevices trying to sync etc, is there a way to disable this or at the very least kill the noisy fan?

I have been battling with fan speed on my iMac recently.
I installed iStat which shows normal temps, but the fan revs up to 4000rpm - for seemingly no reason at all. Sometimes its quiet for long periods. It sometimes helps for a while if I put the machine into Sleep mode, but then I hear the fan start to rev up again when I resume activity.
I have spent hours with tech support, who then upgraded me to a higher level of tech support. But still the problem continues.

I have a black macbook that I got in Dec 2007. While I am using it, the screen will randomly going completely black and I have to move towards being closed until the screen works again. I think it is a short in the screen but I am not sure.
I was hoping someone else has had a similar problem and figured out how to fix it. I was also thinking about taking it into Apple or an Apple reseller to get it looked at but I am not sure how expensive it would be.

There's a macbook I'm considering purchasing on ebay right now. The seller says:
Also, the backlight on the monitor occasionally shuts off. I don't know why but if you close the machine, then open it up, it usually comes back on. This is a known issue with some MacBooks.
I know that sometime Apple will fix known problems for free (like the palm-rest chipping problem). Does Apple fix this for free?

My Macbook Pro (from mid-2010) has recently started running EXTREMELY slowly, and the fan continuously runs loudly. From other posts, I have checked my activity monitor to see if any process is taking up a lot of the CPU % and have found that nothing seems high, except the kernel_task which, from what I understand, is supposed to be high. I have also attempted to reset the SMC which didn't fix the problem either. I have taken my computer to the genius bar 3 times now, and they keep telling me nothing is wrong (because it works perfectly there), but when I get it home the fan comes back on, and everything runs slowly.

I have an iMac G5 that is starting up, then working okay for 1-2 minutes. After that, the processor usage goes way up, and the fans start spinning loudly. It's a first generation 1.8 GHz with a 17" display. Mac OS X Leopard. Recently, it spun up and then shut down and wouldn't start again. The room it's in is < 75 degrees F. No malodor, or other symptoms save for hot to the touch. Has been left shut off and unplugged for a few hours, and still has this problem.

I was a Windows user up until a few months ago so this isn't that big a deal, but lately, my MBP takes longer than usual to shut down. Usually, it's no more than 2-3 seconds. Now, most of the time it's normal, but sometimes it takes like 20-30 seconds and there is a spiraling icon (hard to describe, think of something refreshing or loading) on the blue screen. I know it's not a big deal, but I'd like some kind of explanation as to why my MBP is doing this and if it's a sign of worse things to come.

I've currently got an early 2009 iMac, 2.8Ghz Core 2 Duo and 2GB of RAM. How would a base 11.6" MacBook Air compare to my iMac, occasionally using Adobe CS5 applications for light work on PhotoShop, Premier Pro and After Effects? Or would I be better off waiting for the MacBook refresh for something more powerful?

My new Macbook Pro occasionally makes a strange clicking noise. Not too loud. I can't really tell what's causing it or what it's coming from, but I'm 99.9% sure it's not the speakers. Ideas?

Every once in a while, the green light on my Magsafe adapter will turn off, but the computer will indicate that it's still running off of AC power. If I unplug the adapter from the computer and then plug it back in, it'll immediately light up again. or some times i tap on it and it start again!

I am currently in possession of a powerbook G4 15" which is having difficulties when charging. The battery i feel is fairly old as it does not retain charge well when not plugged in. The charger has recently become temperamental, charging at a very slow rate, if at all and usually works if held at a certain angle. The last few days i have noticed that the green ring around the charger port occasionally turns red and have unplugged the charger and left it.

I have some issue with my 2012 Macbook Pro Retina. The screen intermittently decides to just not work. Sometimes on startup i hear the start up noise but the screen doesn't turn on. I am able to remote into the computer when the screen doesn't work. I can't seem to find any rhyme or reason as to when it works and when it doesn't. I've reset the PRAM and SMC sometimes that will bring the screen back sometimes not. Â
