I tried to install Windows 8.1 using bootcamp assistant on Yosemite. After installing Windows 8.1, it asked me to restart.
When I restarted it stuck on blank screen. I've heard the startup noise but nothing happened. I tried many startup key combinations such as; Command(Alt), cmd+R,cmd+V,T, but the screen is always blank. Although the screen light is, on the screen is totally blank.
I did resetting SMC, and also I did cmd+alt+P+R (I've heard 4 times startup sound) but the screen is always blank. Nothing happens. I can only shut down by pressing the power button for 4 seconds. As a result when I power on, I hear the sound but nothing happens. Nothing on the screen.   Â
What I did before was: The system is a brand new mac. I bought it 1 week ago.
1- I tried to install windows 8.1 using bootcamp. But failed. Because windows installer gave me an error that windows can not be installed on GPT partition.(I have also MacBook Air and MacMini with bootcamp Windows 8.1 working fine.)
2- Then I rebooted using Alt key then booted to MacOSX and deleted the windows part and many combinations. But failed. The error was always the same GPT error.
3- I reinstalled Yosemite tried all the steps but failed with the same error (GPT error)
4- We had another same macbook pro. And we could install windows 8.1 easily.
5- I compared the two machines in windows setup. The problematic mac had first partition labelled EFI.
6- Then after a few hours. I tried to install again. And saw that the EFI label was gone!. But I don't know how this is happened.
7- I was happy and started to install windows. After installing the system gone!!.
Info:
MacBook Pro with Retina display, OS X Yosemite (10.10), 13' 256GB SSD 8GB RAM i5 (Mid 2014)
First of all, I have a Unibody MBP 2.4 GHz from October 2008. Today my sound card died. Or half died. My left speaker doesn't work anymore, and the sound card must have fried my headphones too, because the right speaker in those also doesn't work anymore (with any ipod / computer).
But this is only one of the many problems I've had with my logic board. I've had my logic board replaced twice for graphical issues, and now I'm experiencing even more issues. Every once in a while, the top 1/4 of my screen flickers black for a couple milliseconds. This happens on only the 9400. But, when I'm playing games using the 9600, it will overheat and my screen will go black and the sound will start looping. To fix this, I have to manually adjust the fan speed before I start playing. And finally, I've had some USB problems too. Whenever I plug in a USB device into my computer, it doesn't get recognized, get powered on. NOTHING happens. I have to wiggle it around for a couple minutes to find the "sweet spot" where it will connect.
All of my problems have been with the logic board.I'm going into the apple store tomorrow. I'm pissed. I shouldn't need to get my logic board replaced every couple months.
Any suggestions? Should I ask for a new MBP all together? Should I just keep putting up with this BS? Anybody have any permanent solutions to any of the problems I've mentioned?
I've got an 800Mhz iBook G4 (640MB RAM, latest update for Tiger 10.4) which has worked without a hitch for the last 2 years. Suddenly it has started going dead while in use - the screen goes completely blank (although the backlights are still on) and all sounds cease. It doesn't matter if the machine is idle, or playing World of Warcraft, or encoding a DVD in DVD Studio Pro. It is completely random. The only way to get out of it is to hold down the power button to force it to shut down. Powering up is also becoming difficult - 9 times out of 10 the machine boots but I get no startup sound. Instead the screen stays dark and the fan goes on full throttle, and nothing happens. Sometimes I can force it to shut down by holding down the power button, sometimes I need to take the battery out. When the machine does boot and I get back into OS X, sometimes it displays a message saying my clock and time/date are set before 2001 and I may have problems.
I understand this message comes up if you reset the power management unit, but on checking the time/date it is set correct. I have tried resetting the power management unit, but it doesn't make any difference. I have run the hardware test CD, and all items pass on the extended test. The iBook's battery is almost dead - this I know! But would that make any difference? With the time/date error that sometimes comes up on restart, it's almost like the internal battery that stores data like the time has run flat. Is this charged by the big battery? I haven't booted into open firmware, but I've read I can run the reset -nvram and reset-all commands from there (not sure what they do). It's not hardware, as the hardware test CD works. It doesn't seem to be a software error (although I haven't reinstalled OS X). Has my RAM gone bad or become unseated?
I'm having a rather annoying problem playing videos on itunes. Instead of the video, I'm getting a white screen with sound. In full screen mode, I'm getting a blank screen, also with sound but no controls pop up when I move the mouse around. I'm getting this with episodes of Lost I downloaded from the itunes store (as well as previews on the itunes store), as well as the "Jake and Amir" podcast. Curiously, if I open the Jake and Amir podcast in VLC it runs fine, but if I try the Lost episodes in VLC they come out without sound OR video. The Onion podcast, on the other hand, works just fine in itunes. This problem, I think, only goes back to when I got the latest version of Itunes.
My MacBook has suddenly gone dark. It charges fine and the battery lights show there's charge. The screen is very dark when powered up? When I turn the brightness down fully, then go to turn it up the screen lights up for a second then goes again?
I recently have been having start up problems, when I would hit the power button I would sometimes hear a healthy startup and everything would boot up and then I just get a black screen and you can still tell it has power. I would start and restart untill it would boot. Now the only way the machine will start is if I unplug the moniter cord and plug it back in then it will start.
I have an old PowerBook G4 that my son uses for simple stuff. One day the screen went dark gray (not powered off) and it won't boot. When I try to boot from a Tiger disk, I get what appears to be a kernel panic. I don't get any strange startup beeps
On my mid 2007 Aluminum 24" Intel Imac shows nothing but a white screen when powered on even though according to the diagnostic LED lights which are all powered on and green the logic board, video card, and everything else are speaking back and forth to each other perfectly fine. Does this mean the LED screen is bad or (from what I've read) is it a possibility the hard drive is bad? I know the optical drive is bad and will not spit out any discs. The #1 reinstallation disc for the OS is stuck inside right now. Before I order a new screen, inverter, and optical drive I figured I should ask in here to see if it is just bad hard drive or something else. Wouldn't the LED diagnostic lights tell me if the hard drive was bad?
Got this mac friday but haven't really played with it before yesterday. My problem is:
1) Yesterday I went for logging in to facebook, but suddenly the screen went green? Had to close the mac down and start it again. 2) After I had turned it on and was on the desktop the screen (with me doing nothing) went white, and I had to do the same again. 3) This morning when I wanted to turn the mac on, it wouldn't! But few hours later I tried again and there I could turn it on by pressing esc + start button.
Should I call for a replacement? (Already had two - 1 with dead pixel and 1 with creaking).
I was using it in my bedroom, it was plugged in. I went to make some food, and upon my return I am greeted by a blank screen, probably just a hiccup right? So I held the power button down expecting it to spring back in to life. But it didn't. It wouldn't turn back on. At all. Luckily, I thought, I have my old 2006 Macbook that I keep as a back up just for times like this. As it hasn't been turned on for a while, the low battery warning comes on, so I plug it in. 10 seconds later, it hibernates. I switch it back on, but it keeps hibernating for no good reason. So I think restarting it will solve the problem. It didn't. It too, now wouldn't turn back on. At all.
In the space of a few minutes, they both completely died. I've tried resetting SMC, PRAM, everything I've found on Apple's support page and forums like this. Nothing has worked. The light on the power cable glows orange when plugged in, so it is still charging, and the battery indicator lights on the side of the MBP work fine. Aside from that, they are both completely lifeless...........
when I turn on my computer there is a blank screen. You can still hear the normal noises coming from the computer like any normal boot-up. But if I let my computer sit for a while without turning it on, it will turn on with weird almost static noises. If I force shut down then try again, I get the normal boot-up noises. I tried the safe boot-up method,holding down the shift button while turning the computer on, but no dice. I actually tried this method on both the good and static noise boot-up.
Yesterday I was working with my MBP in one of my client's office and the computer went blank. The screen turn to black and it was still ON. I had to press the ON/OFF button to shut the computer.
I'm trying to upgrade to LION to move to iCloud...the folks at the genius bar recommended that I go from 2gb ram to 4. They gave me the website to purchase the memory and told me how to load it. Prior to loading, I shutdown the computer and unplugged it. I then removed the 2 1 gb cards and replaced with 2gb cards. The loading seems to have gone fine, but all I get is a power light on the front of the case and a sound that makes me think it's running....the screen is totallly black though.
I have a MacBook Pro with 10.7.3 installed. When I go to my system settings and click on iCloud the page is blank. Just grey screen in the window where it should show whatever should show with iCloud.
I am currently running OS X Lion. There are no system updates. My macbook pro JUST started doing this. It never did it before. When I shut my computer and let it sit for however long and then open my computer, the screen comes on, and then about 5 seconds after that, the screen goes blank. In order to turn my screen on, I have to adjust the brightness on my keyboard EVERY single time.
I haven't used my built-in web cam in months now and out of sheer bordem decided to play around with Photo Booth, to my surprise nothing was showing up. It's just a blank screen. The little green light by the lens goes on, but nothing comes up.
I'm trying to fix my GF's Macbook Pro. This thing since day 1 has had so many little issues she's replacing it with a Dell. Anyhow, I want to try to fix the computer and I'm very good with computer hardware, just not familiar with troubleshooting Macs. The computer when turned on doesn't make a sound, it just sits at a blank screen with the power LED on the front lit solid. I have tried resetting the PRAM, resetting the SMC, and reseating the memory. I even swapped the memory.
It's the same behavior each time, just sits there, nothing comes on the screen. No noises. It does get quite warm sitting there powered on, though not obscenely hot. I can power it off with the power button as well. I have heard of trying to boot off of the restore CD or something but I feel that won't work and the problem is most likely hardware related. Nothing strange happened before this computer stopped working. It was not dropped, no water, or anything like that.
Specs are the machine is as follows: 15" Macbook Pro 2.2 Ghz Core 2 Duo, 2GB, 128MB VRAM, 120GB 5400 RPM Drive
my macbook was almost dead on power when I shut it down. I couldn't charge it because I was on a plane. Anyway, I plugged it in recently and tried starting it up, it makes the start up sound but won't get passed a blank white screen. Is there anyway to fix this? I've heard reinstalling the startup cd might work, but will I lose my files on it? All the pictures of my dog that just passed away on it, and I don't want to lose these. I just got the right cds to back them up and was going to.
This has happened 2 times (rarely). Basically, when I wake up the macbook pro, the screen would remain "blank". I know the screen is on because I can see the mouse pointer but the whole screen is black. I'm assuming Finder has crashed?
I don't know how to restart on the macbook (ctrl + alt + del didn't work, using option didn't either) so I just held down the power button for 4 seconds and restarted that way.
I was using my computer normally, it started to move slowly, so I properly shut it down. After leaving it off for a few minutes, I started it up again. However, every time I press the power button, it comes on and there is just a blank gray screen. No folder with a question mark on it, just a blank gray screen.
It just started this afternoon, every 15-20 minutes the screen goes blank once for less than a second and comes back. I haven't upgraded to snow leopard yet, haven't changed anything recently. It's only a few months old so should I take it to an apple store or is there something simple that might fix it?
When I access a certain website (eyetube.net), the website loads and displays for about 5 seconds and then the screen goes blank. All software has been updated and Java latest version has been updated.
I was using my MacBook Pro and all the sudden the screen started to flash and then went gray with lines and then black. I turned it on and off multiple times, tried to restart it but the screen will never turn back on. The computer makes the noise like it is turing on and the keys light but but the screen doesn't change.
