G4 17 display blinks slightly when sleeping

I've been searching for this problem, but cannot find any documentation anywhere, my apologies if it has already been covered here.
This blink is sort of on the right side of the screen and is timed exactly to the pulsing of the LED on the front. I checked in the dark and it's still doing it with the lid closed. In a bright room it's not terribly noticeable,but in a darkened area very upsetting. It doesn't matter if the power supply is connected or not either. The screen is normal when using it and perfectly black when only the display is sleeping. But when the powerbook goes to sleep(pulsing light) there it goes again. It wakes normally from sleep as well. I would imagine this is really not doing my battery or screen any good when sleeping.
I don't think it used to do this and wish I had a firewire drive to boot on to see if it would do it from a clean OS there. Thinking of wiping the drive and starting over, but have so much stuff and software apps on here that is like a nightmare to consider.
Any thoughts?

Well no replies as of yet, but I have made progress. In the bluetooth settings the box for these devices to wake computer was checked. If you add a device it will check this box automatically even if it is originally unchecked. Un-checking this box seems to resolve the problem. I guess this is relieving even though I did have plans to use this powerbook to run a display using bluetooth wireless keyboard and mouse. Thus I guess I will have to use a wired input instead. I find this somewhat disappointing if this is the only solution, so rather then marking this problem answered I'll leave it open for now. Something for the real apple gurus to spin on .. My iMac is also running bluetooth and doesn't have this issue.

  • Why does my iMac display go off when I am starting up or waking up my machine from sleep..

    Why does my iMac display go off when I am starting up or waking up my machine from sleep..?
    When my iMac goes to sleep I then later try to click the magic track pad or keyboard and it will usually then show the initial password entry login screen and then go off. The machine is still on but the display is black and will sometimes flash up the screen again if I press the magic track pad or keyboard but will then black out again..

    Well, there are many different reasons why it does this. It might shut off due to power voltage problems, system overheats, or there is a System Problem. The reason it might be hard to boot up is because your power button might not work properly or your system hard drive is damaged.

    I have a problem with my iPhone 5 stopped working the sleep / power and simultaneously refused to obey the HOME button. I can not use either one or the other. I can not enable or disable the device, display lights up when you plug the charger. same display works fine as it is surprising. or maybe someone knows what is the reason for this? is there any way to solve this problem?

    More than likely its a hardware issue, I have never encountered such a problem and best bet is to just go get it replaced. If you have insurance on your device apple will replace it as long as there was no water damage, if you dont have insurance they will charge $200 more or less. Hope you get it fixed

  • Display Changes Resolution When Computer Wakes From Sleep

    I have a MacBook Pro bought in May of 2006. In the last year, this problem has been getting progressively more annoying to me. When the computer wakes from sleep (not every time, but most of the time) the screen will flash blue, then reset the resolution to 640 x 480, I think. To fix it, all I have to do is go to System Preferences and change the resolution, but when I do that, it pops up two windows, like it thinks I have a dual display set up. To fix this, I always click 'detect displays,' and it fixes it, but the next time I wake the computer from sleep, it does it again. This isn't really an urgent problem, but I would expect my computer to behave a bit better for me.
    Thank you in advance for any aid you might give me.
    Lisel

    Hi Lisel. I have a similar age MacBookPro that does the same thing. I don't really know how to fix it I'm sorry, I wish I did cause it's annoying. I just thought I'd let you know you're not the only one with this issue.
    Basically, for some reason it thinks it has two displays connected, even when there isn't. To stop it being a total pain, make sure when it does come up with the two Display Pref windows to set them both to 1440x900, at least then when it does go dual display it won't be 640x480 and you can still read stuff.
    I've also left the Display Pref icon on the top tool bar (next to the AirPort and Bluetooth and stuff), so I can just click that and Detect Displays. When it does that it figures out for itself it doesn't actually have two displays connected and so goes back to normal.
    I know that's a workaround and not a fix, sorry. I'd be keen to know if anyone else has any better solutions:)
    Thanks,
    Mark.

  • IBook G4 blinks out when screen moved; use crash logs to diagnose?

    My iBook G4 (bought 1.5 years ago) blinks out when the screen's position is even slightly adjusted. Sometimes it doesn't care to wake from sleep, either.
    Would it be possible to figure out what's going wrong by examining the console logs?
    Thanks - if this is the time for a repair, I'm hoping the computer itself can tell me the problem.
    Greg

    It sounds like you may have two different problems. Waking from sleep and shutting down because of movement are probably not related. However, I would recommend you have an Apple Authorized Service Provider check out your iBook out for the crashing problem first. That could be a hardware problem. Once that's been eliminated, then you could start troubleshooting your wake from sleep problems.
    The logs might be much better at determining a software problem, since you can see what command or software might have been causing trouble. If your iBook shuts down because of a hardware problem, that kind of trouble isn't really being tracked by the logs. Only the operating system & software functions are.

  • A1038 Cinema Display doesnt wake after sleep

    I picked up an Apple cinema display A1038 for real cheap with hopes to make it a second monitor for my 2011 mac mini. I hooked it up to my G4 powermac to test, until I get the correct adapters for my mini. It worked when powered on and I ran a movie to see if it would stay on and it did. After the movie was over the computer went to sleep and now it will not wake up, just black screen with the power light on the display blinking occasionally. If I hard reboot the computer the apple loading screen appears and than it goes black. I tried swapping the video card with another one I had laying around but same symptoms. If I unplug the display and unplug the computer for a few mins, everything will start and run fine until the computer sleeps again. I also have a G5 powermac but I haven't tried the display on it yet. Any suggestions?!

    The USB circuitry in the display may be failing.  This can interfere with computer sleep functions.   It that's the problem you may be able to use the display successfully when using a DVI to ADC adapter by not connecting the adapter's USB cable to the computer.  You won't be able to use the display's USB ports or control its brightness from the computer.  I have been using my 22" ADC display this way for five years since its USB started causing computer sleep problems.
    Be sure to get the Apple version of the DVI to ADC adapter.  Other brands may not work in conjunction with a Mini DisplayPort adapter.

  • External display blinking on Macbook Pro Late 2008.

    Hello,
    Firstly, computer specs:
    Macbook Pro, 15-inch, Late 2008
    GPU: GeForce 9400M / 9600M GT
    8 GB RAM
    320 GB Hard Drive
    On Mavericks v10.9.3
    I want to connect my computer to my TV via a mini displayport to HDMI adapter, for gaming purposes. As such, I want to use the 9600M GT as my GPU. However, when I am in High Performance mode (which uses that GPU), the TV screen blinks on and off every couple of seconds. I have tried resetting my PRAM, which failed. I know it is not the adapter, because it functions when used on another laptop. I know it isn't my port because it works when in Battery Saving (using 9400M GPU). Can anyone help?
    In short:
    Late 2008 15-inch Macbook Pro, GeForce 9400M / 9600M GT
    Mini displayport to HDMI functions when on Battery Saving (GPU = GeForce 9400M)
    However, external display blinks on and off when on High Performance (GPU = GeForce 9600M GT)

    Hi mjbecker2,
    Welcome to Apple Support Communities!
    The article linked below has some tips that  may help you resolve the flickering issue that you are seeing on your TV.
    Apple computers: Troubleshooting issues with video on internal or external displays
    http://support.apple.com/kb/ht1573
    No video or no signal, image distortion, "snow," or flickering
    Check connections
    When using an external display be sure to check the following:
    If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
    Monitor and Display Adapter Table
    About Mini DisplayPort to HDMI adapters
    Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
    Thunderbolt ports and displays: Frequently asked questions (FAQ)
    Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    Try unplugging the video adapter or cable and then plug it back in.
    If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
    Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
    If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
    Cheers!

  • Satellite A300-PSAG8E - HDD indicator is blinking even when i do nothing

    these are my problems
    1. My HDD indicator is blinking even when i do nothing ( blinks every half second or so)
    2. When I go somewhere my display turns off and when I move my mouse display turns on but nothing is happening. Everything is standing still (sometimes 20 seconds, sometimes 2 or 3 minutes ) and than he is ready to work.
    Upgraded BIOS to version 2.20
    OS: Windows 7 Ultimate
    Laptop: Toshiba Satellite A300-PSAG8E
    Anyone know the solutions?
    Need help please! Thank you

    > 1. My HDD indicator is blinking even when i do nothing ( blinks every half second or so)
    Even if you dont touch the notebook, the HDD is running and different applications access the data. The applications and processes which are running in the background would cause this blinking. Note; this is not a problem!
    > 2. When I go somewhere my display turns off and when I move my mouse display turns on but nothing is happening. Everything is standing still (sometimes 20 seconds, sometimes 2 or 3 minutes ) and than he is ready to work.
    Disable the stand by modem and disable the settings which disable the screen while notebook is not in use. This can be done in Windows 7 power management.

  • External displays not going to sleep?

    Environment: Early 2013 MBP Retina 15'', OSX 10.8.5, two external HP LP2475w monitors connected via DP-DVI adaptors. The monitors are correctly recognized in the system report.
    I am not running a screen saver, and in the Energy Saver preferences, I have set the display to go to sleep at 15minutes (long before the computer goes to sleep).
    The built-in display indeed goes to sleep at the predetermined time, but the external monitors simply get a black screen, they don't actually go to sleep (indicator light is green, the backlight is still on). There is no problem with the monitors, they correctly go to sleep under both Windows and Linux.
    My theories:
      (a) vesa information about how to turn the monitors off is incorrect
      (b) something about the mini displayport to dvi adaptor kills that signal
       (c) there is no way to turn off external monitors, I'll have to live with this
    Help?
    Thanks!

    exactly the same here. 2011+dell 24"
    i called apple hotline and they did this with me:
    http://support.apple.com/kb/HT3964
    and
    http://support.apple.com/kb/HT1379
    after this the external monitor went to sleep flawless. ... but as soon as some usb-ports are busy (with an external drive or something) - even when everything falls asleep the external monitor keeps on again.
    but a least without the usb the monitor now falls asleep too - so there is hope!

  • Display constantly going to sleep on OSX Lion

    Is anyone else having this issue after installing Lion? My display will go to sleep at random intervals when I'm using my Macbook. Sometimes it's once every hour, sometimes it goes once every five minutes. The display will go black, the backlight on the keyboard will shut off. All I have to do it click the track pad to get it back, but it's getting increidbly irritating.

    Same issue on my 2012 Mini.  I have a WD 1TB drive in a Macally enclosure.  Worked OK with FW800 but with UISB3 will not always wake up when TM wants to do a backup.  I then have to turn it off and power up the drive again.  I wish I could keep the HDD from sleeping but WD has a built in sleep function that I cannot control even though I have unchecked the go to sleep function in my Mac preferences energy menu.

  • 20" Intel iMac - DISPLAY LOOKS YELLOWISH WHEN VIEWED FROM AN ANGLE?

    Just got a brand new 20" iMac and the display looks great when looking at it 'straight on', however when viewing the display from an angle (and just a slight angle) all of the white and lighter colors in a photo change to an annoying 'yellowish' color...go figure?
    Is this normal or ???
    Are there any settings to adjust in the System Preferences / Display?

    Thanks George for the link...
    Wow...little did I know about the dreaded viewing angle of a TN display. In fact, I went to an Apple Store yesterday and checked out several 20" and 24" iMacs and every 20" iMac had the viewing angle problem while the 24" iMacs showed no signs of this issue.
    I plan to return the 20" unit and upgrade to the 24" iMac...thank goodness for the 14 day return policy, however with the 10% restocking fee...ugh!

  • B320 Display Blinking

    After inactivity, my B320 frequently enters a state where the display blinks ON and OFF with an approx 1sec interval.  During this state, the PC appears to be usable (mouse, keyboard, etc work fine...) its just not practically usable.  The LEDs in the bevel at the lower right corner of the screen also blink, but the HDD, BT and WIFI LEDs do not.
    The only resolution I've found is restarting.
    So far I have updated the Intel driver and tried different resolutions, to no avail.
    I'm not entirely sure how to trigger this, but it consistently happens when the display turns off due to inactivity then I come back.
    This is a 6mo old refurb B320.
    Any thoughts?  Thanks, Nat

    The problem just occurred while my B320 was in use, so it is not a result of inactivity.

  • 23" Apple Cinema Displays gos black when routed through DVI extenders boxes

    I have an ATI radeon 9650 with two DVI ports. My new set up requires my Mac to be further than the dvi connector's present lenght to my 2 HD cinema displays. I purchased 2 DVI extender boxes. Once connected the Utilities does not show the displays as Cinema HD Displays. And worse yet they both go black and the power light blinks. When I hook up the 23" directly through DVI to the G5 both displays come on. However the one connected through the extender box still shows the wrong display profile.
    I have check and re-checked the cables, extender boxes, my graphic card and all seems to test out properly. I know this because I have another G5 with same specks that I have tested these hardwares on. Finally I thought it was my Bootup drive so I did a full erase and clean reinstall. the monitors worked fine for 10 minutes and then when I clicked on Displays in system pref window they both went black again. I can only conclude that the DVI extender box is somehow changing the signature of the HD Displays and the the system freaks out!
    THE MODEL OF THE DVI extenders are DAS 101,and 101R
    www.cooldrives.com/cadvexcat5dv.html ;
    I am at my wits end. I need to get to work before I loose all my clients. PLEASE SOMEBODY HELP!
    PS total lenght of CAT5 DVI extenders from Mac to Display 15ft max

    Naelm G, I just read your first post a little more carefully. Is it true you are only trying to place the Cinema displays 15 feet away from the Mac? That's not very far. If you don't care about also extending the Firewire and USB, then you might be able to get away with a simple 10 foot DVI extension cable like this:
    http://www.monoprice.com/products/product.asp?cid=102&cp_id=10209&cs_id=1020903&pid=2406&seq=1&format=2
    The combinded length of the Cinema's built-in cable plus the 10 foot extension cable will be more than 15 feet. This would be the cheapest way to go by far.
    Or if you want to extend the Firewire and USB along with the the video, then Gefen makes an extender that will do that:

  • Menu toolbar icons not displayed in colour when deployed on the Web

    Hello!
    We are developing an application using Forms6i on Windows NT.
    Our problem is that menu toolbar icons are not displayed in colour when the application is deployed on the Web using lookAndFeel = generic. This is the case both when using Microsoft IE5 and Netscape 4.5. When lookAndFeel = oracle, however, the icons are displayed in colour.
    The icons are stored as *.gif files in the same directory as the application *.html file. It does not help to create a virtual path /web_icons/ in the www listener and edit the parameter default.icons.iconpath in the file Registry.dat.
    When running the application as client/server, the menu toolbar icons are displayed in colour as expected.
