Powermac g4 cube, power button blinks twice

hello,
     i have a powermac g4 cube, i plugged it in and it turned on (i could here it) and i went to go turn on the apple display and i pressed the button as normal, and when i pressed it, it lites up and when i let go the light goes out. it is a yellow light on the display. so i grabbed a differnt display that i had laying around and plugged that in and it went right into standby mode, i then looked at the mac and saw that it was blinking twice. i went online and read the it was a incompatible ram issue, first off, i just took out the ram and that would show a 1 blink, and second, would no ram cause the display issue? i just want to know if it is the graphics card or if im just not doing somthing correctly. one other thing, i opened it up and noticed that it was missing a few screws and it was wiggley, so i replaced the missing screws and it made it secure, but this still did not resolve the issue.
thanks

would no ram cause the display issue?
Yes. No RAM, bad RAM, incompatible RAM are all contrary to function.
If you don't have compatible RAM, the machine will not move to logic. If there is no logic function, the machine will not move to graphics initiation.
One must reach successful logic before one can have graphics.
Deal with the RAM issue first.
Install known good, guaranteed Mac compatible RAM.
Standard PC RAM almost never works.

  • Power button blink twice each time, video included. Laptop won't turn on. help please!

    Hi guys,I opened up my laptop - HP Pavilion dv6 because the fan was full with dust.I cleaned it up and followed the youtube instructions. I know I assembled the laptop correctly, each part in his place, every step went smoothly.When i tried to power up the laptop, it didnt turn on. At the beginning i had 2 blinks in the power button with the f12, i did a hard reset and now i got just 2 blinks on power button. here is the video i took, please help me!!!http://youtu.be/JjRhWZw4W8Ithanks!   

    Rebuild the unit from scratch..... There may be a shorting part

  • IMac powers up fine.  Wireless keyboard and tracking pad not recognized. Power lights blink twice, repeatedly. Any ideas?

    My iMac was off during a recent thunderstorm. When I power up the computer all is fine.  However the wireless keyboard and track pad are not recognized by the computer.  Their power lights blink twice, go off, then blink again. Any suggestions?

    Turned out that I had to disconnct the keyboard from the new iMac in order to show in the old iMac.

  • Why Power Button blinks after overnight ShutDown. Restarts Shuts Down?

    Funny enough, My APC shorted out from another piece of equipment that went bad. Blew my room circuit breaker as APC smoke arose. Learned lesson, 'Dedicate your APC to your Computer(s) only! Testing showed I fried my Mother board! I bought and replaced the exact Motherboard version. Ran the 'Hardware Disk' all systems nominal, reset fan speeds. Hooray! Back in business!... 10 days later, I shut the Computer down. The next morning, the Power Button was blinking erratically. Not showing normal codes! Able to start up- fans, sys, monitors fine. Then, 'click', power supply shut off. Did the usual unplug power and peripheries, pmu, batt.. Time enough to run Hardware disk to know CPU, memory, drives,fans ok... Shut Down! BEFORE I GO TO REPLACE THE POWER SUPPLY, Are their any other thing I can check, i.e. Power Management, suspect Connectors, Power Button?? ANY IDEAS? PLEASE HELP! An Intel Mac Pro will be next but the changes and upgrades will put my Studio in Gremlin ****! THANK YOU!

    >  think this is normal.  Any vaguely recent  think this is normal.  Any vaguely recent ...
    Sorry - this is not normal...let me clarify....when I click 'Start' -> Shutdown -> select 'Shutdown' or 'Hibernate' from the drop down list, and press enter... It does shutdown or hibernate as appropriate, BUT IT ALMOST IMMEDIATELY STARTS BACK UP.  This is not normal behavior.  When you shutdown, it should indeed power off and stay off, until you press the power button again.  That is normal.
    The last physical contact with the computer is pressing enter on the "Shut Down Windows" window...I do not close the lid, move a mouse, or anything else...I merely watch it shut down or hibernate, and start right back up...
    Please note, I have attempted to search for a solution, but I don't know the 'specific' terms to look for...as shut down or hibernate doesn't fail, it succeeds, it just 'turns back on' or 'boots back up' as if a ghost pressed the power button to turn it back on....
    My advanced power settings are set to:
    When I close the lid - do nothing
    When I press the power button - hibernate
    When I press the sleep button - sleep (I never use sleep)
    I am sure the power button itself is not malfunctioning, because when I press the power button in Win XP, it indeed Hibernates, (before starting back up)  If I 'shut it off during POST' and press the power button, it comes on as normal.
    Any other guesses?

  • My Power Mac G4 booted from an OS 9.1 install CD, and then froze up.  Now I turn the machine on, beeps 3 times, power button blinks 3 times.  What does this mean?

    I tried to install Mac OS 9.1.  I turned the computer on, heard the bong noise (although with some static), and inserted the OS 9.1 installation CD.  It started to boot, but froze up.  I rebooted the machine, and the same thing happened.  One more reboot, and i get 3 beeps and the power button is blinking.  What does this mean?

    Hi, it indicates a RAM problem, (or Logic Board around the RAM).
    The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
    If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
    1 beep  = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable
    In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
    Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

  • P67A-GD55 Won't Power On - Onboard Power Button Blinks

    I just built my Core i7 system with the P67A-GD55 motherboard and I'm having a problem.  I've got all my components installed and when I plug my power cord into my power supply the system won't turn on.  The power button on the motherboard repeatedly blinks green, but doesn't do anything.  My case power button won't do anything at all either.  I've read through the manual and searched through the forums and haven't been able to find an answer.  Any help would be greatly appreciated.
    Mobo:  MSI P67A-GD55
    CPU: Intel Core i7-2600 3.4GHz
    RAM:  Patriot Gamer 2 8GB (2x4GB) DDR3-1600
    HDD1:  Crucial M4 64GB connected to SATA1
    HDD2:  Seagate 7200.11 500GB connected to SATA2
    PSU:  Silverstone ST60F 600W
    Video: ATI Radeon 4670 1GB

    PSU has 42 +12V amps on the single rail, so that shouldn't be a problem. Could you please check the green sticker on the BIOS chip to see which version the board was shipped with? Guessing 1.8 or 1.9? I have a feeling it is a RAM compatibility issue. The very newest BIOS's have improved support for both G.Skill & Patriot memory modules, but you have to get into the BIOS initially to set the RAM up manually to possibly get to the point of loading the OS for the BIOS update. To rule out a possible bad stick of RAM, try to start with each of them singularly in the first blue slot, & just one HDD, & with VGA installed.

  • Power button blinking

    Someone PLEASE help I'm panicking! I have an HP stream notebook, it's a touchscreen and I know it's windows 8 (the model is 13-c002dx). So I had it on and it was working fine. I closed it, went downstairs, came back up, and when I opened it the screen didn't turn on. The power button is just blinking. I pressed it, the keyboard, plugged it in, everything. The screen's just not turning on and the light won't stop blinking. What do I do? I don't think I can take out the battery and I don't want to tell my parents because they'll think I did something to it. Do I just wait for it to die or something? 

    Hi @Dahlia24 ,
    Thank you for visiting the HP Support Forums and Welcome. Thanks for all the information about what is happening to your system. I have looked into your HP Stream 13-c002dx Notebook and getting a flashing power button on startup. Try performing a hard reset.
    When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
    You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
    I hope this helps.
    Thanks.

  • PowerMac G4 MDD power button flashes but doesn't boot

    My PowerMac G4 MDD will not boot when the power button is pressed. The power button lights up for about 1/2 second and then goes out. There are no noises at all. No hard drive spin-up, and no fan.
    For the past few years, in order to get the machine to boot up, it has been necessary to unplug it from the power source and plug it in again. I have read about other people having this same exact problem and remedy. Now, however, doing the unplug/replug thing no longer gets the machine to boot. The power button will light up briefly only after an unplug/replug. Subsequent pushes will not cause it to light up until another unplug/replug is done.
    I have removed all peripherals, including the video card (only card that was in the machine), 3 of the 4 RAM modules, disconnected the hard drive and DVD drive power cables, and disconnected the fan, and removed the PRAM battery (which I know is probably dead), and this makes no difference in the behavior: The power button lights up for about 1/2 second and nothing more. I also disconnected and reconnected the power supply cable to the motherboard. No difference.
    There seem to be 2 possibilities: I need to get a new PRAM battery and press the PMU reset button, or my power supply has gone bad.
    Before I buy a PRAM battery, I am investigating the power supply to see if I can tell whether it is good or not. Some people with similar problems have discovered blown fuses in their power supplies. Before I open up my power supply and look for that fuse, I have a question for anyone who had that fuse problem: Did your power button still light up, even briefly, when your power supply had the blown fuse?
    Best regards,
    Dave

  • Iphone 4s power button jammed twice

    I Purchased the Iphone4s in Nov. 2011. The power button jammed in August 2012. They replaced it for free and 5 months later it jammed again. They said since it is out of warrenty that I had to pay for a new one. They showed me how to use AssistiveTouch. It very annoying because I  waste battery because I can't lock the phone and sometimes the phone does not automatically go off beause it is  in my pocket.
    I understand it is out of warranty, but the power button is a well known defect in the Iphone.
    I really like the IPhone 4S but this is the 2nd phone that barley made it halfway through the intended warranty. I want to get another Iphone when my upgrade is avalaible, but I can't see bying another Iphone and having the same issue.
    What should I do?

    If your upgrade is to another 4S, then you get free replacements for 2 years with the AppleCare if the button dies. So, even if your luck is on the bad side again, you'll pay for that AppleCare in two replacements. You can always get the $69 AppleCare which does the same thing, except it doesn't include provisions for accidental damage.
    Anyway, you're luck with it happening to two phones isn't good, but it's also unusual. If the phone was a refurb that might have something to do with it.
    I mean, I would say go for it, cause even if the lock button does jam, you get a hardware coverage for the first year, which means you don't pay to fix it, just take it to an Apple store for exchange. You pay $69 when you upgrade, then you get that perk for two years. I say it's worth it.

  • 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?

  • Printer offline, no response to unplugging or pressing blinking power button

    It has never had this problem before, I even downloaded the print and scan doctor and it says nothing is wrong with the printer. It just says the printer is offline, the power button blinks and has no response to when i press it. The test print page wont print, and the status jusy says error. I tried the open and close 4 times thing, and checked for paper jams. Everything is also installed.

    What printer do you have? What operating system do you have? I am including a document that addresses printer offline message.

  • Blinking Power button on T410

    Hi,
    I have a T410 and just noticed today that the power button is blinking green, whenthe machine is switched on.
    If i reboot it goes away for a while but then starts blinking again.
    What does this mean? 

    Hi nuri,
    just a suggestion.
    The power button blinks because your system went into standby. (You mentioned that the battery is set to optimize lifespan).
    To wake it up, try to press the blue FN key on your keyboard. bottom left position.
    hope this helps.

  • Power button flashes when I try to scan HP Deskjet 2514

    I first had a problem where my printer would not stop printing, even though I canceled it.  I looked it up and followed these instructions.  From the Desktop, hold down the Windows key and press R.  Into the Run window, type services.msc and hit enter.  Browse down to the print spooler service, right click it and select Properties then click on the Stop button.  Now browse to C:\Windows\System32\Spool\PRINTERS and delete the job inside this folder - You may need to click a prompt to gain the appropriate authority to open the PRINTERS folder. Restart the computer and you should find the document(s) have been removed. I didn't know which one to delete, so I deleted everything in the folder.  Now,  my printer will print, but everytime I try to scan something, my power button blinks and it won't scan.   Please help!

    Hi , I read your post and see that you were able to resolve the issue for the print jobs not cancelling out, but now you are unable to scan. I would be happy to help you.
    Make sure the printer is connected directly to a wall outlet. (don't use a power hub or a surge protector) This ensures the printer is receiving full power and may help this situation. Download and run the Print and Scan Doctor, it will diagnose the issue and might automatically resolve it. This software will also troubleshoot jobs stuck in the queue, which you could use in the future if the issue occurs again. What were the results when you ran the Print and Scan Doctor? (did it print or scan, any error messages) If you appreciate my efforts, please click the 'Thumbs up' button below. If there is anything else I can help you with, just let me know. Thank You.

  • Dual G4 won't turn on. Power button just blinks

    Hi everyone, first off I'd like to say that I know there are a number of similar posts to this but I read many of them and I think mine is a little different.
    Earlier today my Dual 1.42 G4 powermac was on and was in the screen saver. I pressed the sleep button on my Apple 23" display and nothing happened. I waited about ten seconds and, needing to leave, pressed it again and left. Well, I returned now and found the computer was off. I pressed the power button on the display and nothing happened. It just blinked. I then pressed the power button the computer and it did the same, just blinked for a second.
    I just followed Texas Mac Man's directions from other post by unplugging the power cable and removing the battery. Waited ten mins and tried power it up and nothing happened. Same issue. There are no start up chimes/beeps and the fans do not spin up.
    I also found a link that showed how some powermac's power button go bad and that a usb keyboard with a power button can start it up. My display has a power button and it couldn't turn the computer on so this isn't my issue, right?
    Some info about the comp: Dual 1.42, OS 10.5, everything stock except a ram stick I added three years ago. Thanks for your help in advance and can't wait to get this old champ running again.

    I debated starting yet another "my G4 won't start" thread since my problem is more similar to Tammy in MO's.
    My Dual 1 Ghz G4 (Mirrored Door) won't start up when I press the power button. The power button usually does not light up upon touch. The computer does not shut down on me when I am working on it.
    The only way to get it to start up again is to unplug the power cord from the back of the computer for a minute or two (not long at all) and then plug it back in again. If I do this, I can run the computer all day without any problems. Once it goes to sleep or shuts down, then I have to unplug it again and start over.
    I have done the following:
    Replaced the battery.
    Reset the PRAM:
    http://support.apple.com/kb/HT1379
    Reset the PMU:
    http://support.apple.com/kb/HT1939?viewlocale=en_US
    as well as done the PSU test:
    http://discussions.apple.com/thread.jspa?messageID=9301520&#9301520
    This last test yielded no voltage results, best I can tell.
    Truth be told, I don't think I did the PSU test properly since the ends of my voltage tester are probably a bit too large to properly test the pins.
    http://img244.imageshack.us/img244/4280/fw800pinout.png
    I even tried to discharge the power from the logic board:
    http://discussions.apple.com/message.jspa?messageID=582223#582223
    BTW: The red led on the logic board does come on and stay on when the unit is powered up and running.
    I was wondering if this has happened to anyone else, and if anyone knew how to solve the problem.
    At this point since this machine is relegated to my wife and kids so for me it's more annoying than anything else. Any other suggestions or advice would be appreciated.
    Thanks in advance.
