when I'm using my ibook it sometimes blink and then goes blank/black and I have 2 shut it of manually and then when I boot back up I hear the chime but get nothing but a black screen
View 1 Repliesbefore I went to bed, I was playing the Sims 2, when my iBook G4 crashed. Our power cord can be a bit dodgy, so sometimes that happens. I didn't really think about it much, just closed the laptop and went to sleep.Last Monday morning, I opened it and pressed the power button. It began turning on, and got as far as the grey screen with the apple and the spinning circle. And then it just froze. The circle stopped turning.
I freaked out a bit, and restarted it a bunch of times, each time with the same result. (One time it stopped spinning, and then told me a restart was required. Huh. The rest of the times the exact same thing happened though.) I even tried unplugging and removing the battery, but it made no difference. So eventually I just shut it and decided to try again later.Last Tuesday I opened it and pressed the power button without much hope, and again the apple and circle came up just fine, then stopped, but then a bunch of words and numbers popped up.I'm a complete computer noob, but they don't look good to me... or are they good?

My friend has an iBook that keeps freezing. This startup screen appears every time. Though I have seen it before, it never reoccurred for me.

Lately, my iBook G4 has been freezing a LOT. I'll be watching a video, filling out a form, blah blah blah, then all of a sudden mouse cursor cannot be moved. Keyboard is functionless. Windows remain without animation.
I've installed a gigabyte of RAM into my well over a month ago. Basically all throughout August it worked fine, no freezing or anything. Every now and then it would act funny after waking from sleep causing me to reboot, but that was it. However, the RAM is not installed an extremely secure fit. I tried for hours to get it to fit in a way I thought was proper. I'ts secure, it doesn't move. I took the RAM out and put it back in again to make sure it was ok. I also managed to make the plastic keyboard lock (the ones you press down to take-off the keyboard on an iBook) pop-upp and render itself functionless. That shouldn't be a big deal if I bring the iBook to Apple, should it?Anyway, my main questions are:
1. If any, what are the primary causes of such freezing in Macs/iBooks?
2. Does it seem the RAM would be a problem, or is there possibly another hardware or software problem?
3. Is there anything I can do software-wise that may remedy this? I know freezing is one of those things where the source problem is difficult to determine, but I am willing to try a few remedies for possible problems.
whenever I try to open up itunes or empty trash or launch other applications, my screen will blink once and then nothing. I keep trying to launch itunes and a small screen will come up saying that itunes quit unexpectedly...other applications or empty trash and the screen just blinks, once.
View 2 Replies View RelatedI've had this 2.0 Ghz 1gb ram Macbook since September 2007 and this was the first time I've ever had any problemas with it. So let me start from the beginning.
It all started this year. One day I picked up my Macbook and turned it on and I noticed that the screen was blinking quite a lot... then it started to get worse to a point I got really worried and it started to annoy me. Sometimes I'd boot it and Leopard would be changing my wallpaper every second (it's supposed to change my wallpaper everyday according to what I've setup in system preferences). While blinking the colors would get messed up and when I closed the Macbook and let it on, sleeping, I'd open it and it would be on the blue screen as if I had just turned it on.
It's worth mentioning that I was running a version of Leopard I downloaded from a torrent and had installed it from an external hard drive. So I thought I should try to format the machine, erasing everything and installing a new and original version of Tiger. Once I installed AND got all updates installed as well it was running perfectly. The blinking had gone away.
Yesterday I installed some new updates, booted and used it fine. Today I turned it on and it won't go past the blue screen and the apple logo won't show up as well. My Macbook just won't boot... I've tried booting on safe mode, booting with the tiger dvd on, i've tried resetting the pram and everything else I could do. The apple logo won't seem to appear and the machine won't boot.
First the blinking screen and now it won't boot.
Any other suggestions besides taking it to a support store? It's worth mentioning as well that I live in Brazil and support to Apple computers isn't as great and cheap as it is in the US. I've had this Macbook for less than 1 and a half year.
my screen keeps blinking on and off every 10 seconds or so and if I let it rest for a while it settles down but everything is missing from the screen except my screen saver photo.

This seems to be a very common situation with the ibook g4... but maybe someone has some advice for me since I cannot log in at all even with my ram problem.
Doing the Hardware test i was given this error:
ERROR CODE
2MEM/1/4: DIMM1/J31
I have searched this code on google and it turns out to be a problem with my ram.
The big problem is that when turning on my ibook, it shows the grey apple screen, loads to the loading screen. This screen loads everything except the last thing, which says "Loading Login Window".
From that point on it does not continue.
How do i correct blinking screen on my laptop?

my Boot Camp install of XP—I successfully partitioned the disk in my new Mac Pro to install XP, but my problem occurs when re-booting to install XP itself. When the machine rebooted the first time to install, it stopped at a black screen with a blinking white cursor, old-school DOS style. Second time when I rebooted and held down Option, it spit out the Windows CD. When I put it back in and it appeared and I tried to select it, it spun up, looked like it was going to work, and then spit it out again, whereupon I got a DOS prompt asking me to put in a bootable volume and press any key. When I inserted the CD, it spun up, but pressing keys on the keyboard did nothing. I tried rebooting again. This time holding option yielded both the Mac HD and the Windows CD (no spitting out!). Taking this as a good sign, I selected the CD and waited. Same black screen with blinking white cursor as last time, no other response, no prompts, never progesses to an installer, pressing keys didn't help.
Has anyone else run into this problem? This is a brand new Mac Pro with the Radeon in it, I have a USB keyboard and mouse hooked up, and it has the latest firmware update.
EDIT: Seems the CD was bad. Slipstreamed SP2 into my original CD and went. Now I just need to get those ATI drivers.
What o I do I have done command, option, p, r at start up etc. I will not go to the desktop.

I am running OSX 10.5.8. A little while ago I successfully Boot-Camped my hard drive and installed Windows 7, but i recently got a new hard drive. I copied over my OSX partition successfully, but didn't copy over the Windows partition. On my new drive I went through the boot camp assistant and created a partition and inserted the Windows 7 disc. But when it restarts, it just seems to hang there- it's just a black screen with a blinking white underscore(_).
I have been told that because I copied over my OSX partition it didn't set up the MBR on the new disk, is their any way to fix this? (besides doing a clean install of OSX)
Are there any software or guides available to help me fix this?
White MB about three years old. Was watching something on Hulu and HDD started making strange noises and screen froze. Forced reboot and only got white screen. Couldn't even get into single user mode. Got a new WD hard drive thinking it would fix the problem. Put in my backup of the Install Disk (lost the original like an idiot) but all it shows when I hold down the C key is a large blinking folder icon with a question mark on it. Still can't get into single user mode. I may have screwed up the backup of the Install Disk or am using the wrong DVD since I forgot to label it.
View 1 Replies View RelatedI've got a nasty issue with my 13-mo. old MacBook.
I'm pretty sure it's a dead logic board and possibly a dead hard drive, which I really, really, really hope not as I don't have backups of everything on the drive. I just upgraded to Leopard this past week and did a clean install so not all of my stuff is setup yet.
Power adapter and battery are inserted. All 3rd party peripherals and RAM have been removed.
MacBook does not chime at boot. The screen flickers, but stays black. If I hold down the power button then try to let it boot the light on the front right flashes constantly (like when it's sleeping but a faster pace), like a turn signal on a car. I can hear the cd-rom drive whining but everything else is dead silent.
I've done everything here with the exception of calling Apple.[URL]
I've also tried FW Target Disk Mode, but the MacBook drive does not show up.
I've done everything I can think of and I'm out of ideas at this point.
Additionally, there's a cd-rom (Tiger Restore CD) stuck in the drive. Holding down the mouse button during restart does not eject this CD. Where is the force eject button (I see no pinhole)?
I have business documents, emails, etc. that I HAVE TO get off this hard drive. How can I do it? I don't have a 2.5" drive enclosure but if that will solve the situation I will pick one up asap.
I have the infamous bugged model, the Late 2008 Macbook Pro. Famous for its screen flickering on the 9400M Nvidia graphics card.
I am currently using the 9600GT Nvidia card, and have some across a few... problems. First of which: Hard Freezing. I know this will happen occasionally, but I had to shut down my computer 3 times in 4 days because of a hard freeze. 2 of the times, the hard freeze was accompanied by my screen just going absolutely CRAZY.
Here is a slight example of what it's doing, but it's not exact (since both times it did something different):
[URL]
Both times, before the hard freeze and flickering, my iStat Pro told me my CPU temp was between 99 degrees Fahrenheit and 103 degrees Fahrenheit. I am wondering if these low temperatures could have ANYTHING to do with the freezing. This problem has just cropped up recently, and I have never had such low temperatures on my mac. I have Fan Control installed because my fans on my laptop weren't cooling off my laptop well enough... the 9600M GT card runs really hot.

The other day the screen started blinking randomly. It'll flicker for a few seconds and then go white with vertical grey lines for a few seconds. Then it will go back to normal. There doesn't seem to be a pattern to it. Sometimes it will go through that process for five minutes and then stop. Other times I can be working on it for hours and nothing will blink or act screwed up.
View 7 Replies View RelatedMy iMac's HDD is fried. The computer just froze so I decided to reboot it and was presented with that lovely blinking question mark folder. I tried it again (and every time since) I get the good old apple logo on the grey screen with the spinning loading thing, but it never progresses past that.I threw in my old Leopard install disc and it asks me where I want to install Leopard, but the HDD option never appears, nor does it in Disk Utility. So what do I do now? It's Sunday where I am (Melbourne, Australia).I'm not too sure if it's still covered under the AppleCare Protection Plan. Should I take it to an Apple store? I remember when my mouse broke I tried taking it there and they told me to take it to some authorised repair place. I'm not too excited about hefting the iMac to the shops only be told they can't

Just came back from the Genius Bar at Apple Amsterdam. Both iTunes and iPhoto had problems launching and libraries were not loading. Ruled out hardware problems so they tried installing OS Snow Leopard over my 10.5.8 in a way to keep my documents safe. All went well until halfway it said it couldn't install succesfully. Made a new appointment for in 3 days from now. They would then overwrite the current OS with the new one so i should go home and make sure to back up all my files in the meantime. Problem is that when i came home and started my laptop i got a blank/white screen with a blinking documents folder symbol with a question mark in it! Does anybody know what it means and will i be able to ever make a back up of my documents?

are these two LCDs swappable? Can I stick a G3 iBook Screen into a G4? I have no idea and I'd like to have some idea.
does the hinge and everything line up, too?
just installed 10.5.6 on their last gen. iBook.She left the iBook plugged in to the mains and came back to find that the iBook was alternating between the grey Apple screen and a light blue desktop screen where she could see the cursor. Sometimes it would also switch to a blue screen without a cursor.
I've tried holding shift during startup - no effect.
I've tried rebooting NVRAM - no effect.
My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!
View 1 Replies View RelatedI have a 2008 Mac Pro, which has served me well since I got it, at least until a day or two ago. At that time, it started exhibiting sporadic black flickering on screen, paired with freezing. At first, everything would freeze except the audio, which would continue playing uninterrupted, and after a minute or so the system would unfreeze like nothing happened. Now, though, it seems to have gotten worse; the system doesn't seem to recover after a flickering episode, and even the audio will get stuck into a one second loop after a while.
I tried resetting the PRAM and the SMC. When that didn't work, I tried restarting into Lion Recovery mode with Command-R. For some reason, that sent me right to a reinstall screen, but it didn't matter, because the screen started flickering and the system froze almost immediately after startup. I'm pretty sure that what it froze in was a separate recovery partition, so that should rule out any software issue. I'm guessing that my video card is fried, but I'd like to see what others think; I'd like to avoid buying a video card that I don't need.
