MacBook Pro :: Its Overheated During The Night And Gave A Black Screen When Starting Up?
May 14, 2012
My macbook pro overheated last night while in sleep mode. I starting it this morning it just kept a black screen and would do nothing else. Tried holding down power button for 10 secs and now it wont turn on at all. I pulled the battery out and unplugged the from the charger. Put it back in the computer got warm without even being on. Don't know what to do. Do not have apple care, mac was bought through school and is 4 years old. Is there anything that can be done to save it?
I bought a MacBook Pro 17inch i7 in November 2010 and it was working fine under Snow Leopard and Lion since then. Yesterday I installed Bootcamp and it was workng also. Today when starting from Bootcamp to Lion I had a Kernel Panic (had this never before) and the screen turned black. I just have the energy cable connencted to it, the computer starts somehow (noise) but no Startsound and screen keeps black.Then I made a little mistake by inserting a LION installer DVD. Cannot get this out anymore, even when I press the trackpad when starting it. I changed the internal hard drive to be sure that the problem does not come from there. I reset the PRAM. I reset the SMC. No way to get the laptop back to work.
Info:MacBookPro, Mac OS X (10.7.3), 8 GB RAM, 30 ACD
Every once and a while, usually when my MacBook is running on it's battery, the screen will show a black screen for nearly only a millisecond or two. It's not too bothersome, and it usually blinks back to normal before I can notice it, but nevertheless I don't want it, and from what I can recall, this only started happening after I installed the Snow Leopard Graphics Update. Is anybody else getting these problems on their MBPs or MBs? MacBook config details in my sig.
So my 13" MBP arrived today and unfortunately my first mac experience isn't a pleasant one. The computer wont start. I am hoping I am doing something wrong but I have gone through the step by step troubleshooting and my computer just sits there with a blank black screen. It shows that the charge is full and when I click the power button the little white light glows in front, however, no sound nor no startup happens on the screen.
Can't get back to my desk top. All I have is a black screen with white text starting Darwin bsd. Have tried a safe reboot but after grey then normal blue screen when loading, this disappears and I get back to the black screen again.
So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.
I have been shutting down my MacBook Pro OS X10.7.3 at night.I just read that OSX runs "maintenance" procedures early in the morning (between 3:15 am and 5:30 am) and that if Mac is powered off at that time, that these maintenance procedures will NOT run.True or False? AppleCare says that it won't make any difference and I won't be affected if these night procedures never run. But, if that's true, then why are they set up to run at night? ? I went to the Apple Manual but it does not address my question.Â
I was using my mac the other day and the screen went to static real quick then gave some code to shut down. SO I did HUGE mistake I am guessing. I have only 1 user with a password. When I enter my user password it goes to a blue screen for a minute then comes back and ask for my password again. Before I crashed it was asking for permission to use fonts from my external hard drive ??? not sure why.But I figured I would just reinstall my os x and be ok... not really worried about my info on the computer everything is backed up. However when i restarted and held down the c key while it started with the os disc inserted... I came back 9 hours later and it was still the white screen with the spinning sun thingie.... like it was still loading
So This morning I booted up my MBP 15" and was just about to open an email when the screen become completely pixelated and unusable. I bought the computer in Jan 2007, and it's been my primary machine since then. I took it into the shop here and the service guy said the computer wasn't worth fixing. 3.5 years old and not worth fixing? Is it really not worth fixing, or is this guy trying to make a sale? Could this have been caused by using an external monitor for most of the time I had it? I usually plugged it into my 24" Samsung and used the laptop display as the secondary monitor.
I clicked on verify disk and it gave me an error about disk cannot not be verified because volume is too big... This is on an older style MBP with a 160gb hard drive.. How do I get around this because I can't click on repair disk.
I've been hearing a lot about macbooks overheating, and was just wondering what are the ramifications of it overheating? Does it act slower, or over time does over heating lead to long term defects or something? Are there sings I should look for or something I should do if I sense my mac getting really hot?
My macbook 13" keeps going up to 70 all higher when i just turn on the computer and stays like that...i've downloaded smcfancontrol but it isn't stopping the temp down.
the bottom of my laptop gets very hot within seconds of use. most do (atleast i think) but within a while of using. mine starts to burn my leg within the first five seconds. what causes this and is it bad?
Earlier this evening my Pro (OS X Lion) overheated seemingly randomly. I gave it time to cool down but had to restart it. Not too long after restarting, it started blaring a klaxonlike horn at me. I didn't know what to do so I just shut it down. It's working better for now, but we'll see.

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?
I have a 2007 aluminium imac running Snow Leopard. It needed to have a disk drive replacement recently under applecare. Since I got it back I have noticed a marked dimness in screen brightness starting about halfway down the screen, most noticeable against a window with a white background. It is pristine white at the top of the window but from about halfway begins to get dimmer. Its a bit like being in sunlight and the coming into shadow, or finding mist creeping into the picture.
I have tried recalibrating it but it makes no difference. It might have been there before the repair but if it was I didn't notice it or else I grew used to it but now I find it quite distracting and it does make text a little harder to read as I'm getting on in years and my sight needs all the light it can get. Is it normal or is it a sign of problems beginning to manifest themselves with the display? I wouldn't like to ignore it & find myself out of applecare cover when it does.
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 have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.
No drops or liquid spills. Will this go away on it's own? Any fixes?
I've had my mac for about three years now and everything was working fine. After I installed lion, I notice that this started to happen. I don't lose any of my information though when it does that. It just goes into a sleep mode I guess? Anyways, is this a feature from the lion update? Something standard?
My macbook pro just has a black screen with a small coloured circle on the right of the screen. It is frozen and wont respond to turning it off or on. It is plugged into mains power.
When my MacBook Pro 13" i5 goes into screen saver mode, which is black, it won't return to normal mode. Tried all keys, trac pad, closing the lip and re-opening it, and it won't respond. The only thing that works is holding down power button for hard shutdown, then restarting it. It has happened 8 times in the last 2 weeks.
After an update(I think) I can no longer get into my computer. When turned on I get the apple logo then a grey screen that turns to black but the curser is active . Then there is no more progress to the startup screen
Computer starts (keyboard lit, music plays, caps lock light on), but no screen. I need to open and close 2 - 30 times before the screen will turn on. Once on, the computer works perfectly. I've tried PRAM and safemode reset.
We've had a Macbook now for about 18 months - no problems. However, last night it was very slow in starting-up and then we found it impossible to move any icons around the screen (click+drag). We have just five small folders on the desktop.
Although 'hiding' is 'on', the dock has also disappeared completely and settings for the dock cannot be changed under preferences.
The Macbook won't turn off under 'shut-down', we have to shut-down by holding pressing 'on' button.
