Every now and then, i get these random flash of black near the top of the screen. Its like a quick split second blink. I never had this problem in regular leopard. I'm not sure if I have a faulty GPU but I think i might too cause when I'm on battery power 9400m, the graphic performance goes down.
View 12 RepliesI use my MBP connected to a Dell U2410 and everything has been ok for the last 5 months or so (I got the MBP around the beginning of Feb.). However recently, my display will start flickering (blinking) a blue screen up to the point that it is completely unusable. Often if I simply unplug the mini displayport from the mbp and plug it back in again, everything goes back to normal for awhile. Just now I was able, between flickers, to switch from the integrated graphics card to the dedicated (?) graphics card. Although I did get a few flickers logging back in, so far it's been ok.

OS 10.6.6 has been on this drive since 7/2011 , without hangs but I recently upgraded Firefox to 10.0.2, - perhaps a factor?

Since I use Snow Leopard I get randomly (around 1 to 10 ) freezes. When I get it I can click some applications but can't make changes in it. The beachball keeps spinning for some seconds and after the wait I can just continue working. I first thought it was Firefox, because it almost everytime happens when I am browsing the web, but I get the same with Safari.
It's getting verry annoying now :-(

Is anyone else experiencing this issue? I have a external monitor plugged in and I use my Macbook Pro (2009 Uni) as a secondary monitor. Randomly, the macbook screen just goes black. If I move my mouse on to the macbook screen, I can see the mouse cursor, but the rest of the screen is black! It's driving me mad!
The only fix is to un-plug the monitor adaptor or adjust display arrangements. It's really cramping my style.
Installed Snow Leopard on my 1st gen Mac Pro and had nothing but trouble: random crashes and re-boots that have gotten so bad that now it crashes during boot up. Part way through the spinny wheel you get after the boot-up Apple logo either half the screen goes orange (!) and it crashes, or the centre of the screen corrupts and it crashes or I get the multi-lingual grey screen of death. Same happens if I boot from the Snow Leopard DVD. Pretty unhappy as you can imagine: can anyone suggest anything? I've tried re-seating the graphics card , blowing out the dust and I've rotated all the memory: makes no difference.

my power cord comes unplugged. my battery is 100% charged, and yet whenever the magsafe comes unplugged the whole thing shuts down. I notice the sleep light blinks rapidly a few times then when my cord goes back in things restore? Edit: My macbookpro is a Unibody which is less then 6 months old. I received it as a replacement unit from apple (due to a lemon macbookpro i originally had) Which i figured means that the battery cant be bad, i take extremely good care of my computer.
View 1 Replies View RelatedI own a MacBook Pro 2.4Ghz and my problem happend like this:Last night I stopped playing SC2 and closed my MBP, then this morning I noticed that while it was closed, it had not gone to sleep mode, or at least that's what I thought, because it was too hot and the fans spinning hard. I openned it and showed no video, but remained on. After a 5-sec power button restart, it flashed the sleep indicator once and did nothing else, except for the HD spinned for a sec.I took the battery off and gave the computer time to cool off, because I sensed it way too hot.After I reinstalled the battery, I was able to turn it on the normal way, it worked just fine, but later I closed it again and when I openned it, it showed no video again.I repeated the process of letting it cool down, but with no effect this time.The sleep indicator turns on once and it does nothing.I tried swapping the memories, resetting the SMC, tried booting pressing control + command + r + p, tried booting without the battery, tried booting without the magsafe, nothing has worked.Now what happens when I press the power button is I hear the HD try to spin for half a second and the sleep indicator turn on once.

My Macbook Pro (early 2013, OSX 10.9.4) does not come to sleep mode – 10 secs after closing the display lid apple logo starts glowing (blinking) on a random intervals.
I have tried the following methods that HAVE NOT solved the issue:
* PRAM reset
* SMC reset
* Power Nap is disabled (with enabled I still get the same issue)
* WiFi is off
* Bluetooth is off
* no external devices connected
* no antiviruses or other programs that I would suspect to cause this
* sudo rm -r -f /Library/Prefrences/SystemConfiguration
* finally reinstalled OS X, and I still got the same issue
Surprisingly, if I enter to sleep mode via menu: Apple>Sleep, there seems to be no issue! I have tried changing pmset -1 lidopen 0 to validate if lid is preventing from going to sleep mode, however it has not fixed the issue.
I see this text in the Syslog:

In the last week or so i have been experiencing lock ups every 15-20 minutes, which last for around a minute. The problem has only presented itself after I moved to a dual monitor configuration, although this may be coincidental, given the nature of the problem. The problem only seems to occur when the system is reading from from the main hard disk however testing the disk (and performing a directory/file test) says that the disk (and all others in the system) are functioning properly.
Curiously, any audio playing at the time, regardless of the application it originates from, continues to play while the rest of the system is unresponsive. It also appears as if the keyboard and mouse are disconnected during this time, and the power lights on each begin to flash, and the Caps lock key no longer lights up. I would like to avoid replacing the system disk if at all possible, as i have already had to do this three times since last December, when i purchased the system, due to drives developing faults.

View 3 Replies View RelatedI have a 2 year old macbook that has generally worked well. About 4 days ago, I put it to sleep and didn't touch it again until yesterday so the battery had obviously been drained. I've done this before in the past and whenever I plug the charger back in, the computer starts right up, no problem. This time however, the macbook won't start up, the charger is a solid amber color for about 3 seconds before switching to a blinking green. The screen blinks black (as in I don't even hear the chime and get the gray startup screen) and the little white light in the front blinks quite rapidly. I've tried resetting the PMU several times to no avail. I've taken the ram out and tried each one individually with no changes. I checked the ram carefully as well and they don't seem fried or anything. I've tried plugging the charger in with the battery and without the battery and the result is still the same.
I have another friend here with a macbook so I'm going to test it out with her charger this weekend as well as charge my battery in her laptop and then pop it back into mine and see if it works (although this is really a last ditch attempt on my part).
Any ideas on how to fix it or what the problem is? I don't live in the States so going to a Genius Bar isn't an option.
My wireless will work for random amounts of time then suddenly start flashing on and off. For awhile it won't recognize any networks then find them. I choose my network and again it flashes on and off.

View 7 Replies View Relatedmy Macbook (I believe a 2008 model wouldn't wake up from it's sleep like it does every time I open it (I usually set it to sleep rather than shut it down). I turned it off manually, but when I attempted reboot it does either one of two things:
a) When I simply press the power on button, the screen stays black and the sleep light fades on once, but then fades off and all mechanical sounds abruptly stop.
b) When I press and hold the power button, the sleep light fades on, but then flashes about 10 times rapidly before fading in and once again abruptly turning off.
I have tried this with the charger plugged in several different outlets, not plugged into the Macbook, waiting, removing and putting back the battery. A Google search said it might have something to do with the RAM and pushing it back in, but I have no idea how to do that.
Twice now I have seen a strange, black and white icon that flashes momentarily upon waking my MacBook Pro from sleep. It looks vaguely like an Apple remote. It goes away almost immediately.

So I bought my MBP this past May and didn't have problems with it until now. I recently opened up my photo booth and noticed that the display flashes very quickly into different lightings/colors. It's very strange because the ceiling fan isn't on, and my MBP is sitting still. I've never seen this issue on anyone else's MBP either. I'm leaving for college very soon and don't want to leave unhappy with my MBP. If I visit the genius bar, will they give me a replacement with my one-year warranty?
View 1 Replies View RelatedSo I have a MacBook circa 2007, running Lion (10.7.3). Over the past day or so it has develeoped a problem where upon opening it, the screen will come on for a moment, then go dark. Nothing will respond - it's unclear whether it's completely off or it's like the brightness is turned all the way down and I can't turn it back up. I have to force shut down with the power button, then turn it back on again. Typically once I log in nothing will load, so I have to force shutdown and start up again, at which point I'll get a dialog saying "You shut down your computer because of a problem. Would you like to reopen applications," or something to that effect. I choose no, and everything is back to normal (at least until I take a chance with closing it and opening it back up again).
