I'm having a regular problem with my MacBook screen. Every time I put it to sleep, when it starts back up again the screen stays blank / black. The way to remedy this issue is to close the lid and open it again immediately. Then the screen comes on and no further problems.
Serial: W8905MCX1AQ
It's a 2008 aluminum 13" MacBook with snow leopard 10.6.4
2Ghz Intel core 2 duo with 4gb of ddr3 RAM.
I have an older generation Macbook Pro (the all-silver two-part body style that came out before the current Macbook Pro) that I got approximately two years ago. I do use it quite heavily but have always taken good care of it.
About a week ago, I was using it as normal, then put it into sleep mode and went away from it for an hour. When I came back to it and opened it back up, there was nothing. I tried closing it and re-opening it, still nothing. I did a hard shut-down by pressing the power button until the power light went off, and then restarted it. Even though the computer turned on and the power light lit up, the screen remained black, and the Apple symbol on the lid remained unlit.
I called technical support and they ran me through a list of fixes including holding several keys down and turning on the computer, etc. None of them did anything to the computer as far as I was able to tell. I was not getting any sound, either--whether from having my computer muted or from the computer not working, I'm not sure.
I then tried putting the MBP into Target Disk Mode by connecting it to my sister's MB--no response. Still, the screen remained black on the MBP and no icon for the MBP Disk appeared on the MB. Even though the computer powers up, runs the fan and everything, it appears to be dead for all intents and purposes.
I have two main questions here:
1) What is going on here? Is it as simple as a screen problem, or has my motherboard gone? This is the very first problem I've ever had with my MBP; nothing has led up to this.
2) Is there any chance that my files are safe? I'm currently on vacation and backed up my files prior to leaving, but have done a lot of work since being on the trip and am not too keen to lose what I've done.
Why does my macbook pros screen keep turning blue and how can I fix it.I have to turn my computer off completely and then turn it back on again.

My 2006 mMcBook is dead and parted out. I still have the case and screen, but no HD, RAM, battery, or working logic board. How can I take the screen and make myself an external monitor out of it? I am presuming it's possible. I can solder a little and I love messing with parts from radio shack. So, has anyone heard of this? I tried googling it but couldn't find any search terms that brought me what I wanted.
Basically, I want to convert the video cable to DVI or even better, Display Port, and then figure out how to solder in a power source to just plug into a wall (since I'm assuming it'd be too big of a job to have it powered off of the FW800 or USB from the macbook pro). Is this possible? Since the computer is dead and gone, it won't hurt to experiment. Anyone have any links or guides to this?
I have a 15 inch early 2008 MBP that the screen will not turn on. When i power on, the hard drive makes a sound that its turning on, but then nothing happens, there is just a black screen. The indication light is on, but again, nothing on the screen. I have tried pulling out the battery, resetting everything i can reset, but still nothing.

2. Randomly, the entire screen brightness will switch 'off' - but not go to sleep - it is set at the brightness level, as if you would have turned it all the way down manually. Automatically, my screen goes from:
3. After clicking the brightness button on the screen - when I look closely - the brightness control is set at its previous level, but the screen is not at that brightness! darkest screen (above, right) + brightness settings up
4. In order to solve the issue, I have to hold down the minimize brightness button and then turn it back up, from the lowest setting. This only works about one in five times. All other times, the screen briefly flashes and then goes dark again.

I just bought a 24" screen for my macbook so i can really enjoy movies in my room. I was wondering if there was a way for me to close my laptop screen but still watch the movie ( so i dont see double picture) I know i can dim down the macbook's screen to almost dark but the screen is still on and using power. If anyone knows how to do this let me know.
View 1 Replies View Relatedscreen goes black, laptop seems to have not turned off but nothing can turn the screen on. seems fine after a reboot but problem recurs at some random future inconvenient point in time. problem is annoyingly inconsistent - it will occur at random (no discoverable software or hardware conjunctions), sometimes around once weekly, sometimes less frequently. have already had it in a mac repair, said they fixed it, something to do with graphics card firmware.

This started very suddenly today. I was in finder looking through some pictures when my screen suddenly turned blue. After a second, it faded back to normally, so I continued what I was doing. After about 5 minutes, it happened again, but faded back. It's be less than a half-hour, I haven't touched the computer but the screen is turning blue than fading back every half a minute or so. Every now and then, the screen stays blue for about 20 seconds.
View 12 Replies View RelatedI bought a new unibody Macbook around 4-5 months ago and I've generally been very impressed with it. It's my first Mac and considering all the problems I'd had before with Windows PC's, it's quite a relief.Anyway, here's the issue. When hooked up to my 24 inch Dell monitor there are numerous problems. Originally it just started with the screen intermittently turning itself off and on, and there being a sleep/wake issue. I did some research then and discovered that this was by no means a problem confined to me. Knowing this I was prepared to wait until Apple fixed it with a firmware update or something, as the problem was annoying but not devastating.
However since then the problem has got significantly worse. Not only are the screen flickering, sleep wake/issues occuring much more frequently, but there are other problems. For instance, the menu bar and the dock sometimes fail to show, and I've been having a very weird problem with the Logitech mouse I use. Even though I can move the cursor generally I can't click, and when I can, only the right mouse button works.The same is true with the trackpad, so it's not a problem with the mouse.
When these problems occur the system generally seems to be very slow. I've checked the 'activity monitor' and the use of 'system memory' seems to be very high. For instance, at the moment (I'm using my Macbook by itself) I'm running a few applications (Mail, iCal etc.) and I've got 1.09 gb of free memory. Last night I was running exactly the same applications and I must have had less than 0.4 gb of free memory. The pageout numbers were fairly high as well.
It's strange because when disconnected from the external monitor the Macbook seems to work seamlessly. I just don't understand how some of the problems I've experienced (such as the mouse issue) can arise from problems relating to the external monitor setup. What do you think? Should I be worried that these issues are perhaps indicative of a greater problem? Either way, the problems are becoming hard to deal with. Very disappointing.
i have a MacBook Pro..I had my track pad replaced recently..I am not sure if it has anything to do with my screen, however, the screen is randomly turning gray and white with lines and fading out..What does this mean

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?

I have an iMac G3 which I am VNC'ing in. Its never going to be turned off, and I am never going to look at the screen, so how do I turn it off? I Want to save the CRT, and its not needed. I Know there's a way to actually turn off my MBP's Screen.
View 2 Replies View RelatedI wanted to fix this hardware problem with my iMac G4 20". Basically the LCD screen has a redish tint in the corners, only really visible when displaying something bright/white. Also, when looking at the screen from an angle when displaying a black image, it looks completely red. What's the fault here? Is it the panel itself or the backlight?

View 4 Replies View RelatedI have a 24" 2007 iMac, the first aluminum ones, 4Gb of Ram and a recently upgraded HD to 1Tb (from a 320Gb failed drive). Recently, I have noticed that under some active usage, such as playing World of Warcraft or Excel, the screen will start to turn completely off for 10 seconds, and then back on for 10 seconds. It will continue to do this for about 3 hours, turning on and off every few seconds or 15 seconds. It will mostly turn completely dark but would also sometimes flicker. The curious thing, is that if I continue to keep playing, the screen would cease doing this after about 3 hours and then be completely normal and fine, but the next night.
The symptoms would repeat itself, and would consistently go away after active usage (3 hours or so). Imagine this, as if the iMac itself needs to be "warmed up" for 3 hours before normal usage. It would also appear that if I hit the machine (or tap it), this may sometimes bring a dark screen back to life for a few seconds. I plan to bring it to support, but I just want to get some ideas from you guys as to what this can possibly be.
Some of my guesses:
1) It cannot be software as physically hitting it or my dog barking would affect the rate and speed of the random turn Ons and Offs.
2) It could be a loose connector from my recent transportation of it while upgrading my HD, but then why would it become normal after 3 hours of usage?
3) Maybe something to do with RAM or video RAM? It is faulty, and thus only prolong heavy usage would "run it in" for the session? After not using it for a while, it goes back to its failed state?
I've found a very rough way of shutting it off by going into System Preferences->Sound->Sound Effects and turning off "Play user interface sound effects" but ideally I'm looking for a way to turn off specific UI sounds not just all of them at once.

A friend of mine brought over his 14" iBook G4, 1.33GHz, 60GB HDD and 1.25 GB RAM. The problem with it is that upon start-up, the grey screen with the apple/turning gear comes up, then after a few moments a blue screen will appear, though no box showing the start-up process. I've run a few basic diagnostics on this, including the lovely disk utility (which did nothing), I've run fsck, zapped the PRAM, etc, no success as of yet. At one point, I received a screen with alternating folders, one showing the smiley mac face, the other folder with a flashing "?". I cannot replicate this for the life of me. I have attempted to acquire files via TDM, though am not able to see the hard drive despite using 2 different laptops. Possibly the firewire cable itself is spent, though it's brand new! Here is where I become increasingly frustrated: I ask my friend for the boot disks as the ones for my own 12" iBook don't work (for whatever reason). He tells me that he loaded Leopard this summer (currently running 10.5.2, no updates loaded since), then proceeds to bring over boot discs for a MacBook...:headdesk: To begin with, it seemed like the HDD was fried, however, after running disk utility (and not hearing any negative sounds), it does appear that the HDD is fine. I'm thinking a kernel panic, though not sure how to resolve these.

View 1 Replies View RelatedI have an i7 MBP and this morning I discovered that its fan is turning on and off at about 2 second intervals. It only occurs when the lid is closed and (seemingly) when the battery is at full charge (i.e., the mag safe is green). As soon as I open the lid the fan comes on and stays on for 30 seconds or so then shuts off as if the system has cooled. Any ideas what this is about?
View 8 Replies View Relatedi'm having a small issue with my computer... Its not turning on
1) If i just press on the power button i just hear the optical drive shifting and then nothing.
2) If i hold down on the power button, the optical drive starts up, the hard drive starts up, the sleep light turns on.. glows a little then faints and nothing.
The screen never turns on in either case and i never hear the start up sound.I had this problem twice already and solved it by reseting the Pram and by trying to turn it on and off a few times ( eventually it just turned on.. ) . But this time i guess that just won't do.
My macbook pro just went totally dark. I tried turning it off and then on again. It plays the opening music but the screen is black.
