PowerPC :: Powerbook Internal Display Won't Turn On With External Display
May 22, 2007
For the past few months i have been using an external display hooked up to my 12" powerbook g4. I have had it on a dual display mode so no mirroring. Recently i would open the laptop lid waking it from being in sleep mode and my internal display will not turn on. The apply system profiler does not even recognize that the internal display exists. My external display works fine and has always been set as the main display. If i go to detect displays nothign happens. I have tried restarting the computer, instering system disks, unplugging the external and nothing has worked. I simply cannot get my internal screen to fire back up. When i used to unplug my external display the internal display would switch back to being the main display and everything would be fine. Now i cannot get the internal display to function whatsoever. Please try and help me as a need this laptop working and i will be ordering a mac pro soon for use with my external display.
I have seen people all over the internet saying that their MBP monitor would not turn on, but I have not seen my situation before. I used the computer a week ago (it's a work machine and I'm a part time intern) and both the external and internal monitor worked. I shut it down and when I came back the computer booted up to the external monitor but gave no video on the internal.
I shut down, removed the external monitor (connected by DVI cable) and rebooted. Nothing came up but when I connected the external again it worked fine. This had happened before, but when I shut down and rebooted without the cable connected it came back on immediately. I'm just hoping its not a bad graphics card or something that needs to go in for warranty.
irst off, according to mac tracker the Powerbook I have is the Powerbook G4 15 inch FW-800. I am running Mac OS X Leopard 10.5.6
Alright. About one week ago, I hooked up the powerbook to a 19 inch external LCD monitor with a DVI to VGA convertor, and all was well. It found my supported resolution and everything, worked straight away, etc.
Fast forward to today, at about 2pm (4 hours ago) I was using the computer and everything was working fine, but I had left it on for a few days so I shut it off when I was about to take a nap. I wake up from said nap about 20 minutes ago, turn on my Mac and my external display is only showing up at 800x600. I have no idea how this could have happened. This would not be an issue if my monitor's native resolution of 1440x900 were on the massive list of resolutions to chose from, but alas it is not.
I'm interested in the new iMac but could not work with a glossy display. Can anyone share their experiences of using the iMac with an external display? In one respect it seems like a waste to have two monitors but the base model costs little more than the maxed out Mini and seems like the better option.
I would be interested in seeing photos of any setups featuring the iMac and an external display.
Also, is there a way to turn off the iMac display when using an external display?
While using Google Sketchup and several other prgrams concurrently my macbook air cpu heats up substantiall. I like keeping the air "open" to allow for maximum heat disipation but of course this keeps the air screen on while I only want to use my external monitor. Is the only way to turn of the air screen turning down the brightness and using the "Mirror Display" option or is there another setting which alows my to utilize only the external display while the screen is open on the air?
I have a 12" Powerbook G4 running 10.3.9 Panther. I am having problem booting my computer from a Firewire HD. I have done a search in the forum but cannot get a definite and/or successul solution. Forum moderators and my respected macrumor fellows, please feel free to direct me to a specific link if you find the questions redundant.Recently, I have had the HD making terrible noise and several days ago, the computer cannot boot at all. When I pushed the power button, the screen shows a folder in the middle with a Mac face and switches to a question mark back and forth. However, it just gets stuck at that stage. I suspected that I have a HD problem and wanted to boot from my clone Firewire HD. Unfortunately, the computer will not boot with Firewire HD either.
I am currently experiencing the issues displayed here... http://www.apple.com/support/powerbook/displayprogram/
However my serial # does not fall within the ones specified. My powerbook was purchased in early Sept of 2004, and I have applecare so it will be up in Sept of 2007.
I am unsure of what I should do at this time and am looking for recomendations of how to handle the situation. I am aware that apple will probably try to say that is it somehow my fault and that i put too much pressure on the lid of the powerbook (as this happened to a friend of mine, and she was actually within the serial #'s that were specified in the link above)
I have kept my powerbook extremely protected (at one point I even had it in a neoprene sleeve inside of a hard sided zip case!) and really don't think it's anything i've done, or wear and tear on the notebook (it's in near mint condition other than a few spots just below the arrow and command keys.)
I just bought a 23" ACD and I'm having trouble getting it to work with my 17" Powerbook. I checked it in the store before buying and it worked fine, but at home it's not responding. The display is recognised in Preferences and is giving me a choice of resolutions, the light is on, but I can't get the screen to show anything. I've tried adjusting the brightness to bring up an image to no avail, turning mirroring on, and closing the lid on the Powerbook then waking it again but nothing gives me an image on the 23".
My Powerbook is a 1GHz 17" with a GeForce4 MX 64 MB.
when I woke my pbook up the screen had a horizontal line across it, and below that there is doubling and tripling of the screen image going on. Rebooting didn't accomplish anything and when I take a screenshot it doesn't show up there. I have a 12" Powerbook G4, running os 10.4.11.
Is there a tweak out there that will disable the internal display while using an external monitor WITHOUT having to first close the lid on my macbook because I just leave my macbook plugged in for weeks a couple feet away from my desk and it's become a hassle to first close the lid, then move my mouse, then open the lid for better ventilation. I just want to leave it open and disable the display!
The connections won't allow me to hook up the new LED display to my PowerBookG4 (Mac Pro on the way), but I'm wondering whether I can still just use iSight safely without using the actual display.
I just bought a Powerbook G4 off of Clist. The previous owner replaced the screen with a higher resolution screen from a newer Powerbook. The display looks great, except that it doesn't fill the whole screen. There is a long group of colored lines on the right side, and the bottom starts to show the top of the display (it looks almost tiled and shows the screen again on the bottom). I'm guessing that this is just a formatting issue, but I'm not sure how to correct it.
I was successfully connected my MBP with External Display Philips 107T4, my question is How to Totally Turn of my LCD monitor so I can lid my MBP and use external monitor only. Recently I used this tips. Just restart my MBP and close the MBP, but I really thanks you, if any one have some another tips to do this without restart my MBP. (some times I have a lot off open document and I don't want to re open each document again).
I have an out-of-warranty 2005 iMac G5 running OS X 10.5 in my bedroom. The screen is very unreliable to the point where it stayed off all the time or gave weird colors and I had to purchase an external monitor (via mini-VGA). I have installed (successfully) spanning tools to allow both extended desktop (2 dual monitors) and mirrored display (2 monitors showing same thing).
However, after hooking up the external display, the iMac's bright display lights up my bedroom. I want to turn OFF my built-in display (i.e. no backlight) and have my external monitor act as my main display --- avoids having two displays eating electricity. Is this possible? (using any Terminal commands?) I don't want the computer to sleep, just to turn off the main display (even manually removing wires will work, if I can find a how-to guide on this!)
I know that the web have a lot of tips similar to this that i will ask, but i couldn't find no one exactly with what i want
I bought a new monitor, and mini-dvi adapter, an external keyboard and mouse to plug on my macbook
I would like to know how to turn off the macbook display without having to close it. I want to know that because if i don't close the macbook, both displays are on. If i close the macbook, the computer goes to sleep and then i press some keys on keyboard and the mac wake. In that point, if i open my macbook the display is turned off like i want. But i don't want to have to close the macbook all the time, and i don't want to leave the macbook closed because closed the temperature goes high.
I've recently purchased a broken 1GHz Alum PowerBook G4 12", and the display isn't working. I have a total of two 12" PowerBook displays, and I've tested both. They've worked perfectly fine. Then I've tried reseting the PMU and PRAM, no luck, but they've attempted to work. Tried the Mini-DVI to VGA adapter with my display, still no luck. The keyboard, optical drive, and hard drive works as if it was booting, and there was always a clear chime, even when I've reset the PRAM and PMU (the beep sound when PRAM also attempted). I've inserted a Leopard install disk, and it sounded like it was working perfectly fine. Hopefully it's not a motherboard issue
WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.
We have an iMac G5 running 10.4.11 which developed some nasty colour banding down the screen and have now plugged in an external display. How can you turn off the iMac display so it only outputs through the external monitor?
As the title says, I need a new monitor for my old G5 as the old monitor for it went bust. Apple does not make the old displays that came with the unit anymore and the only available monitor is the new LED ones ? but they all come with mini display ports
I am looking for a display to use with my Powerbook G4 12". I am in love with the 30" cinema display, but according to technical support today, my setup is not compatible (supposedly, but the person on the phone didn't sound to sure). I have a mini DVI, but the 30" requires a dual DVI. I think the 23" display requires DVI, which I can attain with an adapter. Does anyone have suggestions for what I can use with my computer? The bigger the better for me. Also what do you think of the older (plastic case) apple displays?
My external display (HP w2207) seems to conflict with my MacBook Pro (15 inch Retina display, early 2013) since I upgraded MacBook OS to 10.9.4.The external display works at initial boot of Mac but does not work after OS sleeps and I attempt to awaken, and while the external display is not waking, the Retina display flashes through different screen views, which only partially reflect my normal screen, or do not reflect my normal screen at all.
I have a Macbook Air, and i just picked up the new LED ACD from my local apple store. Since im new to mac, is there a way to either close my Air and not have it go to sleep? I want to use the external display as the primary display with my laptop closed, any ideas?
I got an 1.33 Ghz G4 iBook logic board, given to me as a working part. However, nothing else that goes along. I do have all the basic cabling such as speaker and power button, flex cables and such. Also got myself a new external AC power adapter. Now, I do not intend to use this as a laptop, thus, I will not be looking for a battery, just AC use. However, there's a big problem, I've no screen. I know there's this software hack that allows to connect an external display, in order to have a "mirroring" desktop.
I suppose that'd be achievable if I had the original screen to actually do the hack, but I don't have it. So, is there a way that I can just directly connect an external display and completely forget about the internal one? One more thing, suppose I can't do what I have in mind, if I actually found and borrowed an internal display, would I be alright if after the hack I give the internal display back to it's owner and continue with the external?
Can anyone tell me definitively if a 1920x1080 DVI display will work with an Aluminum PowerBook 15" 1.5GHz? When I look at the Apple specs page, it says that it can handle external monitors up to 2048 x 1536 on the external display, but that does not specifically state that it supports this resolution. This one is special because it is 16:9, which is not particularly standard for monitors. The card in this model is an ATI Radeon 970. However, their website is completely unhelpful. The paheon the 970 makes no mention whatsoever of Macs, but does go out of its way to note that 1920x1080 is only supported on some OSes. So has anyone successfully run a 1920 x 1080 monitor on a PowerBook? I'm looking at the ASUS VH242H display.
I've tried to connect my macbook pro and my powerbook with a dvi cable, when I tried to detect display from my new macbook pro nothing happen, does anyone know how should I connect my powerbook as a second display for my macbook pro?
