I have a 2 year old aluminum (not uni-body) 15" Macbook Pro. Today when I turned on my computer, the front light went on, I heard the hard drive spin but the screeen remains completely black.
View 3 RepliesSo 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.
This started a week ago, When my early 2011 MacBook Pro8,2 (running Lion) is plugged in and I close the lid, the light on the side stays a solid bright white. When I open, my display turns on for about a second or two, but then turns off, causing me to have to unplug my laptop inorder to get the display back on.

Macbook pro intel core duo. My macbook is turned off, when I press the power button the light goes on and the computer starts making sounds of turning on for about half a second and than shuts off. I tried removing the battery and putting it again, I tried to hold the power button (the light flickers at one point and eventually shuts off as well after 2 seconds), and tried turning it on with the adapter plugged in and unplugged.

While unhooking my battery, I accidentally touched the metal contacts near the battery cable connector on my mid 2009 with a screw driver. My computer says 'battery not found' and only turns on while plugged in.  The computer doesn't detect a battery in the system profiler. Will buying a new battery resolve my issue?

I recently purchased a ColorVision Spyder 2 to calibrate my MacBook Pro display (I have the 9C83 panel). The results were wonderful—everything seemed to improve colorwise. There is one exception, though: in applications that use ColorSync (Safari, iPhoto, etc.) blues turn purple. Not just a purpleish-shade of blue—purple. The easiest way to see this is by opening a color picker, such as the one in Pages or Adium. Using the RGB sliders to choose a perfect blue—255—it's easy to see that it's purple. Other interface elements changed, too: blue menus, such as when you organize bookmarks in Safari, become purple. I found a long thread about the issue here, but no conclusion seems to be reached. It looks like the color spectrum created by these hardware profilers puts blue very far away from the sRGB blue, causing an adjustment to purple. A lot of people here use calibration tools on their MacBook Pros—has anyone else seen this? And you if have, is there a workaround?

I am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.
I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

I am new to this forum, but hoping I can get an answer here. When placing my Macbook Pro in sleep mode by closing the lid, it goes into sleep mode, but immediately turns back on (with the lid closed), then after a short time goes back into sleep mode and then immediately turns back on. It keeps cycling like this. Any clues to why it will not stay in the sleep mode?

I tried reseting the pram with no success. I deleted the com.apple.PowerManagement.plist file. but it still doesn't turn off, only the monitor.

I have MacMini and the display signal turns off intermittently (i.e. not just sleeping).Â
The display is via a VGA connection to a Philips monitor (although I've tried with an Acer VGA monitor too and get the same problem).Â
The only way to fix it seems to be to turn the Mac off and on again.Â
I feel pretty disappointed. I've used Apple Macs since having a Mac Plus 20 years ago and have always recommended people to use them because "you just plug things in and they work"...Â
But this is simply rubbish. It's practically useless. should I just try to get my money back under the "not fit for purpose" clause in the sale of goods act.

While working on the computer, sometimes the screen will turn gray (from top to bottom) and a message will appear saying the computer must be restarted.So far the local Apple store has not been able to find the problem. The last solution the store tried was to replace the Airport Card, but that didn't work. Computer was purchased in December 2011.

I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything
View 9 Replies View RelatedWhen waking from "sleep" the screen appears normal but, the pointer leaves a trail of grey as it moves and the whole screen will turn grey if I keep moving the pointer. The computer is effectively dead. Have to shut down by using power off for six seconds and then re-starting. I know little about computers!

Late last night, I ran into some problems with my iBook G3. It's the 700 Mhz model, with 384MB of RAM. Nothing else special in terms of hardware config (unless an Airport card is special). OS X 10.2.8.
Basically, the computer seemed to hang and I did a hard reboot, and upon starting up I got a folder with a flashing ? .
I can't seem to find my Install disc 1 to run Disk Utility or just boot up - hopefully I will find that when I go home tonight (or maybe I left it at my parent's place), but I checked using the Hardware Test CD and it didn't detect any problems.
I am having problems opening the CD drive, so I've had to open it using a paperclip. Sometimes it doesn't appear to be using the CD.
I also have run the Micromat test CD that came with Applecare (of course this machine is almost 4 years old so that's finished...) and it detected a problem with the Read Buffer last night, but then I guess the battery ran out while it was on the last test.
This morning, I ran the Read Buffer, Write Buffer, and Volume structure tests and the first two passed very fast (unlike last night), but the Volume Structure test failed. I'm not surprised since I've been aware I have issues with this before. I tried to repair before going to work but at one point it seemed to hang so I gave it another hard reboot.
Last night, I would sometimes get the apple logo with the spinning "clock", and sometimes I would get the ? but it would never get to the login screen.
I have an 13" MBP that I ordered new in April, 2012. It is running Lion. I have an external monitor that is capable of 1440x900 resolution. I have an external keyboard and trackpad hooked up, and I like to close my MBP up and stick it in a BookArc. I want to be able to have the internal display disabled and to have the MBP only allow me to put windows on the external display, so long as the lid is closed. I also want to be sure that I am taking advantage of the resolutions available on my external monitor, which are higher than those supported by the internal display (specifically 1440x900).Â
This doesn't seem to work because I either have to allow the MBP to continue to draw my desktop across both screens (internal and external), OR use the "mirror displays" mode, which restricts my resolution of my external monitor. This means I either forgoe the additional resolution benefits of my external monitor, or I end up with windows that fall off-the-cliff, so to speak, because they are drawn in the portion of the desktop that would be shown on my internal display (which is closed).Â
I've read the community support pages on using the MBP with an external monitor, most relevantly, this page. It simply recommends using the "mirror displays" option. However, this option, as I mentioned above, doesn't allow me to make use of the additional resolution, and my external display looks bad. how to keep the 13" MBP in closed clamshell position, with the internal display disabled, and use my external monitor at resolutions higher than those allowed by the 13" MBP but which are available to my external monitor when not in "mirror displays" mode?

View 13 Replies View RelatedSo 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.

The first time I connected to my HDTV using a mini displayport-dvi and a dvi-hdmi adapter, it worked flawlessly. Stupidly, I set my TV to a resolution it couldn't support. Now the screen only turns blue until System Preferences eventually crashes and the TV gets no signal.
I've tried clearing my PRAM, deleting the profile in the colorsync folder, and even deleting /Library/Preferences/com.apple.windowserver.plist out of desperation. I've confirmed that it's not a problem with the adapters by successfully getting another HDTV to work. Where could could OS X be storing the display's settings?
1.- The imac turned off by it self.
2.- I tried to turned on pressing the turn on/off button and it did not do anything.
3.- I disconected the computer form the wall and wait for some minutes, and it did no do anything.
4.- After about 20 minutes i tried again and turned on by pessing the on and off button.
5.- The imac turned off again and disconected form the wall and conected to another electrical contact at the wall, adn it did not turned on. i wait for some minutes and turned on again, but after about five minutes it turned off again.
6.- I left the imac connected to the wall for a couple hours and i tried to turned onn by pessing the on/off button and it did not turned on.
7.- I left all night connected form the wall and tried to turn it on this morning and it did not turn on.
8.- This time, I only disconnected the imac cord form the back of the computer and left it for a couple of hours, then I concected and turned on
9.- All the times that the computer turned on it started like a restart and no announce or windows appear telling me about an error or something like that.
10.- One of the times I touched the computer at the back and felt it hot, not too hot, but I do not how normal is.
11.- I can feel some very, very little air at the back form the vent.
What do I hve to do? What kind of tests can I do to know if the computer's an is working ok?
