I was on Netflix but all of a sudden my MacBook crashed, it wouldn't do anything, so I held the power button until it turned off. But when I tried to turn it back on, the booting wouldn't complete. It turns on, I hear the chime, I see the apple logo and the "turning on" screen but out of nowhere it turns off. What should I do?

So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.

I can hear the chime going off, but the display turns on you cannot see through naked eye, you have flash light onto to the screen to see very little, can you tell me why this is happening and how to fix this issue. Secondly, can you tell me how to fix this issue, my keyboard and trackpad doesn't work. Is it the problem of flex cable of both the keyboard and trackpad or is the related to software

My screen is black but my laptop is not off.. and its not that only the screen is black, my mac on sleep (i think)...When I turn my mac on, it does turn on.. The starting screen comes out.. but the moment the desktop opens, the screen goes black. And if I try to wake my mac up by pressing any key, the mouse shows for like three seconds(on the black screen, not my desktop). So that means that my mac is not totally off, it's just that the screen is black. But once in a while, when I press any button, my desktop shows for five seconds and the screen turns black again. I had yesterday was that the finder was keep restarting. I was still able to go on all the apps except that I could not open any files on my desktop.
View 1 Replies View Relatedmy MBP is really screwing up these days. Basically the best way I can describe it is that randomly once in awhile (no matter what I'm doing, usually surfing the net) the screen flickers a few times, then most of it turns black (except usually for a small part on top that stays on whatever it was displaying before). The section between the part that stayed the same and the bottom is sort of "multicolored".
The computer does not respond to anything except holding the power button down for 5 seconds until it shuts off. If I try to adjust brightness or sound level, nothing happens. Anyway, I took it in to apple and they claimed it was the motherboard, so they replaced it. But today I had the problem again! What else could it even be? Any chance its the RAM/screen/hard drive?
I went to the Genius bar and they told me to Control, Option, P, R on a reboot to restore the settings, but with a wireless KeyBoard it does not work. I installed my standard PC keyboard, but am not sure what keys renase the display back to factory settings.

So I've got a powerbook G4, thats 8 days past its warranty. Conveniently, it now won't turn on. It won't wont boot from CD. If I turn it on, I get a gray screen that usually just turns my computer back off, if thats not the case I get a screen that shows the finder icon and a question mark and then turns off.
All it will do is boot into open firmware mode. Currently the install disc is inside of it and I've tried booting the cd using "cd:, bxi" and "dir hd", and it can't open both. Does anyone know how to wipe the HD, and start the installer using firmware? Otherwise, I think I'll have to take out the harddrive and plug it into an external case and then wipe it.
Anyone else noticing their new macbook air freezing randomly and the screen just turns completely black? The back light is still on but nothing is on the screen.
None of the buttons work, can't force quit anything, i have to hold power button to turn it off then back on.
It has happened to me twice already, first time when i was installing the adobe suite, second time is when I was working on a school assignment with a simulation app (not cpu or memory intensive AT ALL).
when working on my new Imac sometimes the machine put itself in sleep mode! The screen turns black and I have to enter my password. Sometimes it happens 2 times in 1 minute; other times once in 1 hour.

Son's Eagle Project. Set up GroPro to snap a pic every 10 seconds. Now have 3,000+ photos in Aperture, in slideshow with most running at 1/10th second. Added text annotations.Â
In Aperture - plays perfectly.Â
Once exported - 75% through the video, screen goes black EXCEPT that the annotations I've made are retained - so occasionally a timestamp or comment appears on an otherwise black screen.Â
I've tried multiple export formats, no difference. Am now resorting to inserting timestamp slides between pictures to see if somehow there is a corrupted image that is causing the video export to fail.Â
Have replicated problem after a reboot with nothing of substance other Aperture running.Â

Here is the situation. I have a 12 in Powerbook G4 with OS X. About a week ago I downloaded a security update and once it was downloaded it asked to either restart or shut down the computer. I clicked restart. It shut down and then turned back on but only got to the Apple symbol with the small grey spinning wheel beneath and wouldn't finish booting up past that. I tried turning it on while holding down the option button and it went to the hard disk screen and clicked the right arrow but it still didn't get past that screen.
View 4 Replies View RelatedIt was just an accidental liquid spill, but however my macbook pro has been acting up before all this mishap with the graphics. I thought is was just nothing so I didn't care to bring it to an apple store but when I had to bring it and check it out using the Nvidia video test it presumed a failed video card. The genuius said it will take 2 weeks to be fix until several days later I recieved a call saying it can not be fix due to a foreseen amount of liquid damage. I've spilt other liquid items but wiped it off the keyboard quickly and it still worked. I'm using my MBP right now with an external monitor, it still works fine but with the issue of the screen being pitch black.

When I boot I get a full black screen, and:
/etc/master.passwd: No such file or directory
/etc/master.passwd: No such file or directory
-sh-2.05b#
I have tried fsck -f and it runs, I get the response The volume Macintosh HD appears to be ok I type "reboot" and it starts rebooting again and I get the loop of:
/etc/master.passwd: No such file or directory
/etc/master.passwd: No such file or directory
-sh-2.05b#
Is there any way of fixing this problem? I am running OSX 10.3.9 on a 17" iMac.
A few times now, maybe once a month, I've restarted my (first generation, 2006) Macbook and gotten nothing but a black screen, while the computer seems to be continuing to boot in the background. The boot-up sound plays, and if I leave it to finish, the screen goes from black to a dull grey, and I'm able to shut it down by hitting the power button and pressing Enter, as if the shut-down dialogue screen has appeared. The pattern so far seems to be that if I shut down down mid-boot, by holding the power button, the next boot will still have a black screen; but when I let the boot finish and shut down from 'within' Mac OS X, the next boot works normally. I restart the computer once or twice a week, and this only happens occasionally--but it has been happening repeatedly.Â

I Upgrades to Lion last year. Two months ago, suddenly the screen of the iMac went black. I tried to boot but it didn´t. After waiting one day, it worked and i made a backup and I installed Lion again but this time not updating.It worked, never happened again till yesterday. The screen went black, I still could listen to the song that was playing on iTunes but after a while it crashed at all.Hours later could start the computer doing everything i read here: SMC, PRAM reset, start with D, with shift.... and i made the backup but when i was going to install Lion again it went black again and I couldn´t restart my iMac.I´m afraid it´s the NVIDIA card, but i can´t be withouth the computer some weeks. Is there anything i can do to fix it or to boot at least?

I have a MacBook Pro Core 2 Duo 2.5GHz/250GB HDD/2GB RAM that won't turn on, unless I leave the power button pressed, in which case, as you all know, the computer turns off again. It started about 3 days ago. Set the computer to sleep, shut it closed, took it to another room and opened it. The MBP gave me the blue screen, then black and then... nothing. At first I thought it was the HDD, but now I'm having second thoughts. I now think it's the cpu fan.

I've got an older 15" powerbook running Mac OS X 10.3.9 (i think). Lately my computer screen randomly turns itself off, the whole think going black, like it was asleep or off, but the computer keeps running just fine. Like i might have itunes playing or be burning a disc and that goes on just fine. The computer itself stays running. What I've been doing is putting the computer to sleep by closing the notebook, letting it rest for a few seconds and turning it back on by opening it back out. This fixes the problem for anywhere from 5 seconds to indefinitely, until it happens again. Lately its been happening more. The computer is 4 years old, but the model itself, probably 5.
View 5 Replies View RelatedJust installed Windows XP using bootcamp and usually no problems switching between operation systems. Recently started using an USB modem for my wireless internet connection. Internet works on both Mac and windows through the modem. Now the problem is whenever I restart or switch on my computer, it shows a black screen if I choose windows partition to boot. No problem if I start through mac partition. If I unplug the USB modem, everything goes fine and I have to plug the modem after starting windows. Is there any solution so that I can permanently plugin the USB modem and avoid booting problem?

View 1 Replies View RelatedIt's a PowerBook G4, 15" model A1046, and this is what's going on.
Powers on, checks combo drive, gongs, no flickering or lighting on screen, period.
Tried a PRAM reset several times but it NEVER gongs a second time. I tried booting to Open Firmware and typing mac-boot, blind, but nothing. The keyboard clearly works, as the caps lock light works.
The hard drive spins up, the fans run at normal speeds, so everything else is clearly functional.
I gave my Powerbook 15" G4 screen a wipe and after rebooting it has gone very dark. There is still an image there but I need a torch to see it. I've tried the brightness controls and rebooting several times but it is still the same. Is there anything else I can try before taking it to a Mac repairer.
View 1 Replies View Relatedrecently my powerbook g4 has been doing some funny things. ..--Sometimes it won't turn on when pressing the button but eventually it will. --The computer would not book up earlier and would just stay on a white screen, like the white screen you normally get when booting but without the apple logo.--When my computer eventually booted it worked for a couple of mins and then the screen went a tinted black colour and a box came up in the middle of the screen saying i need to reboot (the box had a power logo for the background)--Then i rebooted and as i was rebooting a black screen came up with lots of writing in white. A bit like on a windows pc.
View 8 Replies View RelatedI have this powerbook from 2005 and no problems up to now..ohhh no!
A couple of days ago started to occasionally make a clank clank noise and getting stacked on the spinning colour circle, only manual restart would do it.
Thought it might be the hard disk as it is a bit old and i never replaced anything on it, shacked it and a noise of something loose would happen, so i thought of opening it up and see if i could reattach anything loose....anyway i started unscrewing following instructions, couldn't get memory out...every screw seems different and so i gave up, put it all back together, praying that the screws are all in their right places and hey, now it wont even start, not a loose sound when shaken though, but not a bip not a light, black screen, nothing...only sign of life is the green light under the num block key and the capitals arrow also starts light
This happened literally overnight a few months ago, and I'm finally getting around to assessing the problem.
This is a 15" Powerbook G4 Model # A1095
I turned it on one morning, and a black screen appears with the following message:
Apr 1 03:19:57 launchd: can't exec /bin/sh for single user: No such file or directory
I have the Software Install Restore Discs 1 & 2.
When I insert Disc 1, I hold down the C key, and the info pops up beautifully. I get really happy at this point. The steps it shows me are as follows:
Introduction
Read Me
License
Select Destination
Installation
I am able to get up to the "Select Destination" portion, where it asks me to "Select a destination volume to install the Mac OS X software"
However, there is nothing listed, so I cannot move on to the next step.
I was just using my powerbook G4 12" when it "clicked", the screen went black and it will not respond. the power cable light is on, and I've tried another battery, but it does not turn on! the little light on the latch button that glows usually, is not on. What has happened to my Powerbook????! I don't have applecare but I imagine I will be calling Apple this morning unless someone can help here
