MacBook Pro :: Won't Restart/shutdown Black Screen & No Keyboard Backlight

Mar 30, 2012

My 2009 MBP would have problems shutting down or restarting. On a shutdown, it would appear to off, black screen and no lights, but if you tried pressing the power button nothing happened. I had to hold the power button to turn it completely, then press it again to startup.Restarts had the same behaviour, it would get to a black screen and I would have to hold the power button and then press it again to startup.I ended up taking this MBP back for another problem, and they replaced it with a 2011 MBP (since I had recurring logic board that failed a few times).Anyway, I swapped the SSD from my old mac into the new one, and I have the exact same behaviour!!Seems to be some corrupt settings or something. So I booted from a Mac installation disc, wiped my hard drive and reinstalled the OS, then I restored from Time Machine, and unticked the option to restore settings.I want to also add, that my backlit keyboard isn't working either.I tried resetting the SMC, but the power light on my charger didn't cycle orange/green, so I'm not sure if it worked. I tried multiple time, following Apple instructions.I also reset the PRAM, which did work.

OS X :: Screen Went Black - Backlight Still On

May 13, 2010

I was using firefox today (all I had open was facebook and gmail) and iCal was open in another space. All of the sudden my macbook screen went black, but the backlight was still on and the music was playing. I hit the space bar a few times and moved around the mouse and the screen came on for a second or 2, but then went black again. It wouldn't come back, so I had to hold down the power button. When it restarted, everything was normal, except that now the fan is going fast and loud, and my computer is getting hot with only firefox open to macrumors.

Desktops :: Mac Pro Goes To A Black Screen When Idle And Won't Restart?

Jun 20, 2009

Recently my Mac Pro has been going to a black screen when idle for a while and I need to power off using the power button and restart. It's not set to ever go to sleep but if I use the sleep function under the Apple, it functions as it should, waking when I touch a key (although I don't let it sit for a while before I wake it). When it is in the black screen mode, it still is performing Time Machine backups.

MacBook Pro :: Won't Start / Black Screen / Keyboard Unresponsive?

Apr 20, 2010

I have a MacBook Pro from December 2007. Currently, when I push the power button to start it up, it makes the initial sound (although sometimes this initial sound is abbreviated, like it's cut off mid sound) but it never sounds the follow-up majestic-type chime. Also, the screen remains black, and the keyboard is unresponsive (The Caps doesn't light up, for instance). The light on the front comes on faintly, but does not blink as in sleep mode. And the fan comes on as well, again faintly, not as in overdrive.

And I'm assuming this next part is coincidental but I'll relay it anyway: The first hiccup with this was yesterday when, in sleep mode, I pushed the front release button to open the MCP and then immediately afterward accidentally closed it again. Upon opening it for the second time the screen remained black. I manually shut it down holding the power button. After two or three times of turning it on and off manually, the majestic chime thing finally sounded and it booted properly. It worked fine then throughout the rest of the day when I would come back to it until last night when it failed again.

PowerPC :: IBook G4 - Blue Screen With Black Box Asking To Restart Computer

Feb 8, 2009

Everytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.

MacBook :: Is Okay To Repeatedly Shutdown / Restart

Sep 30, 2010

i am a teacher in a school where we have been told that every student must shut down each MacBook or iMac when finished. It is not unusual for 6-8 classes a day to do this. I have said putting the MacBooks to sleep would be better for them. Some of the laptops are taking 5 minutes to restart. Can't find data from Apple to support my concerns.

MacBook Air :: Hang On Shutdown And Restart?

Jun 25, 2008

It's been happening for a while now and I had hoped 10.5.3 would fix. When I choose to restart or shutdown, 90% of the time it hangs on grey screen after logging out and I have to hold down power button to shutdown. No apps hanging. Also have problem where when I open the cover to bring my MBA out of standby mode, I'll be presented with the logon screen. I'll type my password and my screen goes blank like it's gone back to sleep but the power light is fully lit. Have to close cover, wait till it goes on standby, then open cover to bring up password logon again. Should I reinstall OS X again?

MacBook Pro :: Any Way To Turn On / Off Keyboard Backlight

May 30, 2010

In regards to a 2010 13" macbook pro's illuminated keyboard.

1.) Is there a way you can make the keyboard's backlight become brighter in low light situations?
2.) Is there a way for the backlit keyboard to turn off in lit rooms and turn on in dark rooms?

For some reason the backlit keyboard becomes dimmer in low light situations. I'm finding it really irritating. I have a feeling this is the way it is suppose to be so that the keyboard doesn't blind you. Any programs to hack the light sensor?

MacBook Pro :: Keyboard Backlight Will Not Turn On?

Apr 5, 2012

I was surfing the web when my keyboard backlight started to fade on and offat somewhat regular intervals. After about a mintue or two of this, the backlight just went off all together. Now, when I press the F5 or F6 key to brighten or dim the keyboard, the keyboard backlight does not respond. The usual screen pop-up that shows how bright or dim the keys are no longer increases or decreases but shows the symbol of O with a slash through (like the no smoking symbol).

MacBook Pro :: Unable To Work With Keyboard Backlight

Dec 9, 2010

My keyboard backlight isn't working... whenever I try to turn it up it gives a circle with a line through it. I have read that there is an ambient light sensor that turns off the keyboard backlight when it is too bright, however that has NEVER happened before and I have used it in direct sunlight and the backlight still obviously works. It's not even bright right now but it won't work. This is very frustrating, there should be no sensor that turns it off it should be the brightness I tell it to be.

MacBook Pro :: Can Adjust The Keyboard Backlight Sensitivity

Aug 23, 2009

Just got a new MBP 15" AG this week and was wondering if you can adjust the sensitivity of the keyboard backlight. It seems to come on even in a fairly well lit room and I mainly only need it in a completely dark room. So I find myself hitting the backlight keys to turn it off and then whenever it wakes from sleep goes back to full bright. Didn't find anything in the keyboard preferences and found a program called Lab Tick which will take care of the level on wake.

it only illuminates in bright settings. if its dark, it wont illuminate. seems backwards to me, why is it doing this? i dont think it was last night when i first got it.

first macbook pro had a blemish on it. now this one the keyboard isnt backlighting correctly.

just read to put my hand over the webcam and it seemed to kick it back into gear. but then it dies and only takes bright settings to illuminate.

edit: maybe its hitting the sensor (some light from the window at a weird area) in a darker room and it works fine i think.

MacBook Pro :: Keyboard Backlight Abnormally Dim When Set On Max Setting

Mar 29, 2012

I have been scanning through the forum looking for a solution, but have yet to find one that works:

Here is the situation:Macbook pro early 2011, lastest update of lion, My keyboard backlight is abnormally dim when set on the max setting. When comparing my current illumination to a properly working keyboard, which i had just a few days ago, the current brightness would be about a level two - three on the illumination scale.

The associated SMC functions appear to be working properly, besides the keyboard illumination.

Oddly: The light momentarily starting working yesterday and went back to full brightness for about an hour, then regressed backed to the problem of being abnormally dim.

What I have done to troubleshoot:Resetted SMC several timesseveral trials of going to a dark roomclicking and unclicking of the "automatic illumination" ticklight does not workIs this a problem with Lion? as there are several characteristically similar senarios involving the keyboard backlight and lion?
