Why does my macbook pro screen stay black when i open it

This is an intermittent problem, it doesn't happen all the time. I just wanted to know if I need to have my computer serviced or if I could correct it.

See this Apple note on starting the system with no video, which may help trouble shoot it.
I'd also run the Apple hardware test (run the extended test) to see if it picks up any hardware error.

Why does my Macbook Pro screen go black when the charger is plugged in while using bootcamp?

While on bootcamp, my computer runs perfectly fine unless I have the charger plugged in. Once I plug it in the screen goes black and starts to charge. I know the computer is still on because I can hear audio from videos if one is playing while I plug in the charger. Once I unplug it the screen comes back on. This makes it so I am unable to work on my computer with the charger plugged in. This is a new problem and did not start once I installed windows 7, it used to work fine. Any suggestions?

Thank you for your suggestion! It helped me with this issue as well. My problem was that I was that Windows had started but wasn't logged in yet--the brightness keys didn't work on the windows login screen. I had to log in to Windows, then plug in the power, then turn the brightness up.
Thanks again for the suggestion!

Why does my MacBook Pro create a driver when I open a .dmg?

When I download any file and try to open it, it doesn't just open or show the folder, it creates a Volume on my desktop. I can't open something if I eject the Volume/Drive for it.

You should install any application into your Applications folder - either by dragging it there or using the intaller if it comes with one. Normally, clicking on a .dmg, a volume will appear and, at the same time, a Finder window should open showing an icon of the application. Drag that icon into the Applications folder. After you do that, you can drag the volume to the trash - it will disappear.

Why does my macbook pro "goes to sleep" when charging?

Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
I read from threads that it is a logic board problem....How do I solve this problem?

Try an SMC reset. Follow the method for "a battery you should not remove yourself."

Macbook Air screen stayed black when coming out of sleep

I put my MBA on sleep earlier today. When I came back to wake it up, the screen stayed black (but somehow backlit). I had to close the top and open it back again in order to wake it properly. Anyone knows what happened? Should I worry about this? Maybe it's nothing and I'm overreacting, but I had so many issues with my last laptop (not an Apple product though) that I kinda became crazy about my computers.
My Macbook Air is two weeks old. It's a 11 inches running Maverick 10.9.5 and every software is updated.
Thanks!

Having something like that happen just once is no reason to be concerned. I’ve seen it happen - it isn’t common and it doesn’t necessarily mean anything is wrong. Being hyper sensitive about a new computer is normal, especially after experiencing the kind of disaster it sounds like you did with your previous computer.

Why Does Retina MacBook Pro (2012) Suddenly Hibernate With Lid Open?

I'd like to know why my Retina MacBook Pro (2012) at certain times suddenly go into Hibernate mode when I'm actively using it with the lid open and what I can do to prevent this.
I know this is hibernate because of what I see in the Console logs and the fact that I can't trigger a wake by using the keyboard/trackpad/mouse. Only the power button causes it to wake up.
This usually happens when I wake it from sleep and plug it into an external monitor via HDMI to HDMI connection.   The lid is open and I use both displays.    This happens about 30 seconds to a minute after I wake from sleep. At the time I'm not plugged into the power supply because I believe it's generally a good idea to let the batter drain and the recharge it. The last time this happened it was about 35% to 40% charged.

This happened again at about 31% power, again unplugged.   Previously, I had plugged in the power before pressing the power button, but this time I pressed the power button before plugging in. The display showed me the out of power icon. Only on plugging it back in was I able to power up the laptop again.
Is it possible there's a bug either with the displayed power or how remaining power is detected?

Why does my MacBook Pro screen have white marks on it and how do I get rid of it?

My MacBook Pro started having these white marks right in the middle of the screen and I don't know how to get rid of it. I brought this MacBook online so I only have the invoice from seller. Is this sufficient evidence to show apple to replace under warranty?

you will have to bring it to apple so that they can determine that.

Why does my MacBook Pro battery discharge even when the charger is plugged in?

I've been having a myriad of problems with my MacBook Pro's battery. The main problem is that when in use, the battery steadily discharges often at a very quick rate even when I have the charger plugged in, the only way I can get it to recharge is to close the lid or turn the computer off, however, it has recently started to take a very long time to recharge (I left it for 12 hours and it charged from 0% to 60%). I also noticed that while off, the charger light occassionaly goes green and then back to orange every few minutes. When I manage to get the battery up to 100% charge, it usually stays at 'Charged' for around 5 or 10 minutes and then it just comes up with 'Calculating...' as it slowly discharges, it also occassionaly claims that it is recharging and that it will take around 6 to 8 hours but it only charges about 1% of the battery and switches to 'Not charging'. Also, sometimes the charger light wont come on when it is plugged in and the Mac refuses to acknowledge it is plugged in for some time.
I took it to the Apple Store a few months ago and one of the Geniuses reset the System Management controller and did a quick hardware test which seemed to fix it but the problems returned soon after, I cannot enter the hardware test screen and subsequent attempts to reset the SMC have done nothing, he also tested the charger and tried it with another charger but it did not help. Hope you guys can help me as I am completely stumped by this and its beginning to annoy me as my Mac is becoming almost unusable.

Why does my Macbook Pro crash almost immediately when I'm offline?

My Macbook Pro (late 2007 if i'm right) crashes randomly, whether I'm using a program or not. Suddenly the whole screen freezes (I see a black mouse and not the spinning ball of death). So I'm forced to use the hard restart.
It started a while ago, when I still was using Snow Leopard. So I did a clean install, and had to buy Mountain Lion. Ever since the clean install there were 3 software updates. But still I'm having the crash problem.
After this last update to 10.8.5 I'm noticing that when I turn WiFi off it almost immediately crashes. And sometimes when I reboot I don't have the time to turn on WiFi again or it already has crashed.
Though I remember that my mac also crashed when I was using the ethernet cable and when i was using WiFi. Only now with the offline modus it seems that crashing is the only thing he can do.
This is what I already tried:
-Making a second account as administrator and start up in the safe mode: but still crashes when I go offline.
-using disk utility to veridy and repair disk permissions: all good.
-NVRAM reset
-SMC reset
I don't know what kind of information anyone needs, but:
Processor 2,2 GHz Intel Core 2 Duo
Geheugen 4 GB 667 MHz DDR2 SDRAM
Videokaart NVIDIA GeForce 8600M GT 128 MB
Software OS X 10.8.5 (12F45)
And my harddrive has 56 gb free right now.

Thank you for your fast answer.
Even though I don't understand the connection between working offline and my videocard I believe you because I see sometimes blocked images when something tries to load or when i scroll down, mostly in photoshop. So I'm considering buying a new computer.
I tested my harddrive a while ago and it still seemed ok. (still i back up all the important stuff constantly).
Though I wanted to ask if you know if the Nvidia is a part of my logic board. I had my logic board replaced in 2010 because of an Nvidia error. So that part isn't that old. Still I can imagine that it doesn't work well anymore with other hardware or software on my computer.

MacBook Pro screen goes black when video is blown up on the second screen

I'm not sure if this is a problem but when I open up a video in fullscreen mode on my second display, the screen on my MacBook goes completely black and I cannot access anything on the my MacBook until I restore the video to windowed mode. Is there any way I can fix this?
Just to add, I can still see my cursor on the MacBook's screen, but there are no menus or docks on there, and I can see my notifications, but other than that, if I attempt to switch tasks and say open up Safari, the safari window on my MacBook will be black, while the video on the secondary monitor is in fullscreen mode.

Obviously there's a bad connection in there. Best bet is to take it back to the GB and show them how it happens.

Why does my macbook pro go to sleep when i move it?

I'll be sitting a my desk and decide to slightly move my macbook pro so its facing me a little better and it will go to sleep.
I have a MacBook Pro (retina display) 13-inch, which I bought in February 2014.
It happened both when I had it connected to power and when it was running just off battery.
I was watching youtube videos at the time, and now that I've stopped the problem has gone away.
What would youtube have to do with my macbook going to sleep?
And now I've gone back into youtube and its not doing it anymore, so confused?

Why does my MacBook Pro make clicking noises when pressure is applied to the unibody?

I purchased a MacBook Pro in late July of this year. Recently, I have noticed that when I begin to type on the keyboard, the unibody will make a faint sound when pressure from my hands is applied to the MacBook. I also notice a faint clicking noise when I pick up the MacBook Pro to move it somewhere. Additionally, the screen hinge makes a faint clicking noise when the screen is opened. Are these sounds normal?

My MacBook Pro screen turns off when I open the lid!

This has been driving me nuts, and also apparently Apple as well.
When my MacBook Pro is connected to a power adapter, if I close the lid it sleeps like a good little Mac. When I open the lid, the display comes on instantly. Then after about a second, it goes black. The LED backlight turns off. I can get it to come on using either of two ways: 1) touch either of the brightness buttons, or 2) remove and replace the power connector.
Now, here is the weird part: it only seems to do it when I am logged in as me. If I login as guest, it doesn't happen. That would seem to imply it is something about my profile that causes it to happen. So I whacked ~/Library/Preferences and it still happened. So where is this particular bit of nastiness hiding?

OK, so I think I solved my issue. It was caused by the system not going to sleep (The screensaver thing was a dead end).
When I ran the console app pmset, I got something like this:
➜ ~ pmset -g assertions
12-06-29 9:11:06 AM EDT
Assertion status system-wide:
   PreventUserIdleDisplaySleep             0

   ApplePushServiceTask                    0
The process that was causing PreventSystemSleep to be 1 was "org.cups.cupsd" which is the print service. So I checked all my printers, one of them was "In Use". When I opened it, there weren't any jobs listed. I went through the options and selected Jobs > Show Everyone's Jobs and sure enough there was a job there. I deleted it and everything seems to work now.
The odd thing is that print job was probably from my other account which didn't seem to have this screen problem. Anyway, I hope this helps anyone out there....

Why does my macbook make a funny noise when I open it?

After my macbook pro has been on the charger for some time & I open it up, it will make a funny noise & the screen will be blue with a bar on it. Takes a little bit before I can use it, Does anyone know what is wrong?

I quit all applications & close the lid. I usually use the charger all time. If I leave it unplugged from the charger, it will not do this. It will make a whirring noise & the screen will be blue over my background, will have a bar on it like it is loading. Then will finally let me use the curser after a few seconds. Only had the macbook for about 4 months. It started doing this about 2 month after I bought it.
If you are still under warranty and/or have AppleCare, call them. Let them deal w/it.

Try a #1 SMC Reset and see the Apple links, if that doesn't work make a appointment for a evaluation.
