Power Button on Display

Just upgaraded my G5 with a 30" Display, however the power button the display does not start the computer as it did with my 23" display. The power button when pushed and the computer is on, it will turn off the computer, but it does not turn the G5 on anymore.
How can I get the power button on the display to not only turn the computer off, but also on??

It can't turn the computer on because it isn't powered through the computer anymore.
The power switch is only sending a command to your computer to shutdown... that isn't the same thing as actually turning it off. You could achieve the same result by selecting "Shutdown" from the Apple bar.
Unless Apple returns to the ADC connector, the days of powering on/off your computer from the display are over.

  • 23" ACD Power Button Issue / Display Options Missing

    One time my dual 2ghz power mac froze upon coming out of sleep mode so i held the power button to power down the computer, but before i did that, i touched the power button on the side of the monitor, hoping to somehow bring up the password prompt out of sleep mode but the screen stayed black and the cursor / ball would just spin for minutes.
    I used to turn on / off my computer and the display would automatically go on / off with it, but now i have to manually power up and down the monitor. And in the system preferences, there is no longer the options section where i can choose what the power button on the monitor does.
    Can anyone help out with why this is happening? A million thanks in advance.

    Your computer no longer has USB connection to the monitor. Do the USB ports on the back of the monitor still work? Sometimes unplugging everything, including the power cord, from the monitor for a while will fix it temporarily.

  • Power Button Displays a Black Screen

    After upgrading to OS X Mavericks, when I press the power button it displays a black screen. I'm assuming this is sleep mode. Before upgrading, pressing the power button would display a window allowing me to choose whether I wanted to restart, shut down, etc. Is there a way to get this functionality back? Is anybody else having this problem?
    Thanks.

    This is a feature of Mavericks.  If you hit the power button it puts the system to sleep.  If you hold the power button for a couple seconds, it will display the menu that you are looking for.  Also, due to the ATX compliant hardware, if you hold the power butto for about 10 seconds, it will hard power off the system without performing a clean shutdown.
    I am not aware fo any System Preference setting to change the behavior of the power button under Mavericks.  There might be a method to control it via a command line setting, but I haven't spent the time to seach for one once I learned that I can just hold the button down for 2 seconds to get the menu.

  • Monitor message" Power Button Lockout"

    New HP 23" monitor -  HP 2310m   Accidentally held down the power button too long; now I can't get the monitor to turn completely off. When the computer is shut off the monitor goes to the sleep mode with the orange LED (on/off switch) always lit orange. How can I turn the monitor off completely and clear the message  "Power Button Lockout"? thank you

    From the manual: Power Button Lockout— Indicates the power button is locked. If the power button is locked, the warning message Power Button Lockout displays. ◦ If the power button is locked, press and hold the power button for 10 seconds to unlock the power button function. ◦ If the power button is unlocked, press and hold the power button for 10 seconds to lock out the power button function. Cheers, 

  • No Chime, display or illuminated power button QS Dual 1 Ghz

    Hi. I have a PM G4 Dual 1 Ghz. It was a great computer until about 2 years ago when it sadly stopped working. I found a broken capacitor on the motherboard (No. 820-1342-B) , so figured it was a bad MB. I replaced the board with a (No. 820-1276-A) board and had no luck. The symptoms-the same as on the new board. I purchased a tested and working board (No. 820-1342-B) and still had no luck. I am beginning to suspect a problem with my processor card or my power supply but I don't want to put any more money into it. I have tried to reset PRAM but the keyboard isn't recieving power. The symptoms: Power light when pressed in, red light on logic board, fans, hd, and optical drive work. No keyboard, display, or chime. Please help- I want to donate this computer and can't bear throwing it away

    You never said if you replaced the PRAM battery.
    I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
    For G4's and earlier models, check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject.
    There are other tips in there too.

  • 17in CRT Studio Display (Blue & White)-blinking power button

    I have an Apple 17in Studio Display (CRT-Blue and White vintage) connected to my Power Mac G5.
    Last night, I went home, and turned it on..or rather tried to turn it on but found it stayed black, with the power button blinking green->amber->green->amber etc.
    As far as the computer was concerned, the monitor was still there and working (dual monitors...the mac kept the b&w as if it was turned on).
    I swapped the monitors to the different video ports and the other monitor worked fine, so it's not the video card or vga->digital adapters.
    I unplugged the monitor and replugged it, and it stayed with the blinking light.
    Restarting the computer with the monitor attached had the computer still running as if the monitor was working just fine, so it seems to be getting what ever kind of feedback the mac gets to let it know a video card is there.
    Anyone have any idea what could be up?

  • I have reached out  to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know why it went black

    I have reached out  to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know
    1. Why it went black and is there a permanent fix for this
    2.Will the IOS gets automatically updated as I feel the IOS was 5 when I got the phone in 2012 december
    3.Do you suggest 7.1 for Iphone 4

    1. There is no way of knowing. These things happen.
    2. The iOS only gets updated when you want it to be.
    3. You should always update to the latest iOS your phone will support. Apple do not write the updates to make your experience worse.

  • DVI to ADC adaptor: Display power button no longer works w/G5?

    I'm looking for answers on a topic originally brought up in this thread:
    http://discussions.apple.com/thread.jspa?threadID=221092&tstart=45
    concerning the Studio Display's power button when attached to an ADC/DVI adapter for use on a G5.
    I am having the same problem. I had previously used the monitor directly attached to an MDD G4, and the power button worked fine. Now that it's attached to the adapter, I can't power up the G5. The brightness button will open the Monitors prefpane, so I would say that it's not a problem with the overall USB system.
    Otherwise things work fine, so it's not the end of the world, but I'd like some confirmation or denial of the problem just to know if there's a defect or not.
    TIA
    G5   Mac OS X (10.4.6)  

    It is working normally. ADC has extra pins to support the power button and light. DVI connectors don't have these pins, so there is no way for the DVI to ADC adapter to make the power button work.

  • Cinema Display and MacBook Pro - Power Button won't work

    I have been using a 20" Apple Cinema Display (plastic model) with a 17" Powerbook and never had a problem. Recently I acquired a 15" MacBook Pro and it's like the power button on the display has no use at all. The only way to turn on the computer is opening the computer lid, turning it on and then closing it. The display also won't shutdown the computer, although the power button light reacts to the touch. The funny thing is that the display settings button work fine. Does anyone has a clue?

    Malcolm, thank you for the answer! But I still don't understand why my new MacBook Pro, having exactly the same connector as my older Powerbook had, won't behave the same way? I'm still using the same DVI to ADC adapter, I'm wondering if the new Macbooks maybe have some PIN assignment disabled on its DVI connector. And anyway, shouldn't the power button be able to at least shut down the computer, as long as pressing it would just open the shut down dialog box?

  • Hello My ipads Power button is not working properly when I press it once it shows option to turn off instead of locking and some other display problems like it suddenly lockes down or display disappears ...Please help. Thank You

    Thanks for that information!
    I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
    In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
    When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
    Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?!

  • I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

    I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

    If it won't turn on then the monitor is dead (power supply?, video circuits?).  Not worth repairing.
    If you have a new iMac then it has thunderbolt.  So exactly what is that monitor you are trying to connect?  For TB you can connect a mini-displayport monitor.   Probably (not 100% sure with TB) can use dvi or vga too if you have the appropriate adapter.

  • Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

    Imac 27" Intel Core7  CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

    I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
    So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...
