Power Mac :: Switch The Startup Disk On G3?
Mar 17, 2012I recently developed a problem where my Blue and White G3 Power Mac will not start in OSX. It starts but then displays a screen that tells in four languages to restart my machine. When I restart I just get the same message.This all started when I switched from booting in OS 9 to OSX. Both had worked in the past. Now I cannot return to OS 9. Is there a short cut of keys to press to bring up the start up disk control panel during start up to try switching back to OS 9?

MacBook Pro :: Have To Long Press Power Button To Switch On
Sep 4, 2014I have macbook Pro running OS X 10.9.4 purchased in 2012 times. For past few days, I've noticed this problem- I have to long press the power button to switch on the device. Normally, the devices switches on with a simple press on the power button. But for the recent days, when I do a simple press of the power button, I think it switches on and goes off instantly. I had to long press (for around 5-8 seconds) to switch it on. After the device is on, there is no problem at all...

Mac Pro :: ATI HD 2600 XT Hdmi Signal Loss To LCD TV After Input Switch Or Power Off
Mar 3, 2008Hook up a $3K machine to a $1.5K display and have to hard power down your $3K machine to get the picture back.When I boot everything is fine. If I change input to TV or power off the display, when I power back up or switch back to hdmi input screen displays error, can't read signal check output device. I have read on this forum about a issue similar with ATV but not with MacPro. In my google searches I read some issues with Vista, but no resolution... thought to be a ATI driver problem. Does anyone know of a tweak to fix the ATI 2600 XT to remember the tv signal after you change inputs or power off the display?

OS X :: Installing Tiger Over Leopard / Freezes - Hard Reboot From Power Switch
Oct 31, 2010I have a 17" iMac G4 that I was rung Tiger with, then I installed Leopard 10.5. I use this as a second computer. All is fine except that my Epson scanner does not work with 10.5. I've tried the latest drivers. I'd like to reinstall Tiger. I used the 10.5 disc to reformat the drive and start from square one. When I boot from my original Tiger disc it starts opening it's windows, but when I get to the point where I can choose Install or use Disk Utility to reformat from the Tiger disc, all windows freeze and I need to hard reboot from the power switch. Am I correct to assume that 10.5 won't let 10.4 to reinstall. Is this correct?

Power Mac G5 :: Get Flashing Globe Of Earth When Turned On
Nov 7, 2007I was working with a Power Mac G5 when this strange thing happened. I had pulled the CD drive from the machine to test out a problem with a new Mac Book computer(door wouldn't open on eject command). Discovered that that we had a wiring problem (I was using the bottom connector not the top). So I go and put the drive back into the Power Mac, turn it on & the only thing on my screen is a small square icon with a picture of the North & South American hemispheres on it, flashing. Can anyone enlighten me as to what just happen & what I can do to fix it?

Power Mac G5 :: Finder Flashing With Question Mark
Dec 2, 2007I searched the entire internet for this solution. I realize it has been posted but the symptoms were note entirely the same. I have a 1.6 g5. One night it was running awfully slow. I shut it down and didn't touch it for the weekend. When I came home the finder/? Thing flashes. Unlike some of the others, mine never boots and I don't have my discs to run the utility. Does this seem like a hard drive problem or am I looking at apples infamous logic board failure?

PowerPC :: 800Mhz EMac - 3 Beeps And Flashing Light On Power Up
Dec 12, 2010My brother has a second gen, 800Mhz eMac (the one that could be overclocked to 1.33Ghz - the earlier PC133 ram model). Since about 1.5 mths ago, when he powers it on, sometimes it will not power on, and other times it will give three beeps (diagnostic pages say bad RAM) and a flashing power/sleep light in unison with the beeps. Did this vintage suffer bad caps? I recall that it was only the 1.25Ghz model that had bad caps, but I could be wrong.

Mar 19, 2008My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

Feb 10, 2008I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.
View 3 Replies View RelatedHardware :: Repair 23" Cinema Display (no Power After Power Surge)
Apr 18, 2008I had a bad power surge (USB hub that was plugged into the back of the display had the wrong power cord plugged in... very stupid mistake I know!!) take out my 23" Cinema Display. The display shows no sign of life (no power light, etc) and the brick has been tested and is OK. My local service place says that they will have to send the display back to Apple which means a minimum of $400 for repair so I'm wondering if anyone has had a similar issue that they resolved successfully? The service place suggested that Apple would replace the logic board but is there any way to test to see if this is the main issue? I have seen logic boards sold separately online but would be hesitant to buy it without know that this would fix this issue.
