IMac :: Intel-Based Unable To Power On - How To Fix It
Apr 19, 2009
I have a 17 Inch Intel-based IMac (2006). when I press the power button I can here and feel fans running but the Power Indicator Light turns on and the screen remains black. Nothing else happens. Not sure what I did. I didn't take anything apart. I checked over the whole compartment and all connectors appear to still be connected.
I did some research figured out how to disassemble the IMac, purchased a new hard drive, backed up the computer and when I took it all apart there was a third connector on the hard drive (temp sensor?). The new drive did not have this connector so instead of experimenting I put the computer all back together.
I shut down my imac and when I went to restart it, I can't get it to get past the grey screen.I can't even get to the apple screen.I have unplugged everything and nothing works.
I just bought my Intel-based iMac last night and it took forever to turn on out of the box. I guess I made a mistake by doing a "soft" power down last night, because this morning it will NOT turn on. I've tried using the power button and waiting. I've tried unplugging and plugging it back in, and then using the power button, and waiting. Nothing works. I've been a PC user for 20 years and just bought this, my first Mac, last night. I think I've made a huge mistake! How the heck do you turn these things on????
I have a 20" intel-based dual core Mac which i have had for about since early 2006, i haven't had any big issues with it until a few days ago when it suddenly shut itself down and refused to power back up. I ran through the checklist that Apple Support provides, including resetting the SMC by unplugging everything and waiting 15 seconds or so but none of it worked. Eventually I just left the power cord unplugged overnight and in the morning I plugged it back in.
After having the power cord plugged in for a few hours and the machine turned off, i tried pressing the power button again and to my amazement it powered back on! Immediately i ran the TechTool Deluxe software that came with my extended protection plan (now expired) and everything was fine. Later that night however, I had left my computer on for a few hours before returning to it and realizing it had shut itself off again. Now I am back to where I started, going through the checklist provided by Apple and am really starting to get concerned. Does anyone know of anything else I can do, short of taking it in to an Apple store? Or is something needed to be replaced?
Information: IMAC-Intel (Early 2006) Mac OS X (10.4.11)
my iMac won't turn on. The day before yesterday happened the same thing, but after a few tries with the power button, it eventually turned on - and all ok yesterday. Both the day before yesterday and today, the general power was turned off for some minutes, but the iMac wasn't running. So now, I've tried to reset the SMC, removing everything attached, but nothing.
At least I can clearly hear the tic tic tic button, probably of the timer, because I set up a schedule to let it turn on at a certain hour. What can I do? It's a white iMac, never had a problem.
I'm sure this has been asked before so please forgive me. I have found arguments that say just use Migration assistant to some saying I need to cherry-pick certain items.
i've got an iMac from late 2006. and i'm trying to upgrade the ram..here's the specs...iMac intel MA589LL/A 20in 2.16 1GB ram 250 gig ect so on the box it says upgradeable to 3 GB of ram... but the computer has two slots... which currently have a 512MB card in each of them. so my question is how do i install three gigs of ram? a 1GB card and a 2GB card? this doesn't seem to make sense, because i thought you were always supposed to keep them balanced.... so should i just install 2 - 2GB cards... for a total of 4 gigs... even though the computer will only used 3 gigs?
How can I format my intell based imac without the original Tiger discs? I have a user account on it that I dont want. I have upgraded to Snow Leopard but I want to to start affresh. I have tried loading the Snow Leopard disc whilst holding down th C key but it goes straight into install mode.
I want to upgrade to Mavericks from MAC 10.6 but I am getting a warning that if I do Microsoft Word and Excel will not work because they are PowerPC based applications. Is there any way to get them to work OK if I complete the upgrade?
I want to partition my external hard drive for my g4 power based mac running Leopard.I will have one partition for Time Machine and the other for Carbon Copy Cloner.Here are my questions:1. Which partition scheme should I choose for Time machine?2. Does Carbon Copy Cloner work the same way for non-intel macs as it does for intel? Do I need to click on the OS 9 check box to make my version of CCC bootable (I want a bootable clone)? Which partition scheme should I choose for Time machine?
Has it frozen more than once since the time you've received it. Hopefully we can get some idea of what's going on. specify what CPU your system is running (2.93 or 3.06 ghz), along with info when you ordered the system, and when it was shipped.
I have a 1.83 Ghz intel core 2 Duo 17in imac. While it was on and working it suddenly went dead. No power no light. I checked the power cord and power outlet.
I am having a problem with an iMac, whenever I plug it in, it trips the circuit breaker it is on. I don't even have to try and switch it on, its as soon as I plug in the power. When I connect the power cable, I hear a pop sound and then there is no power.
Would I have to flash the rom of a Mac pro 8800GT to get it to work in a PC? If so, can someone point me to ROM? Also would it get flashed while inserted in the PC?
This is now the 4th time this has happened, but this time I have at least what I believe to be a cause. After a power outage of about 30 seconds this past thursday all of my printers attached to my imac have disappeared. Not only this, but when attempting to even press cmd p from any program that I could possibly print from slows down the system to a crawl, and eventually crashes. When going through system preferences the printers menu takes about 10 minutes even come up, and when it does, it's empty. When attempting to add a printer back the system once again slows to a halt eventually not responding. I've tried restarting multiple times, making a new user account (which worked for about 3 months the previous incident happened.) The only thing that has fully fixed this problem in the past was to re image the computer.
While installing windows 7 via bootcamp tonight, I suffered a power failure a minute or two into installation. Upon reboot, I have only a black screen with flashing curse. I have attempted to reboot in safe mode, recovery mode and diagnostic mode, but I think the machine is not recognizing the keyboard.
Info: iMac, OS X Yosemite (10.10.1), 2014 21.5" Fusion Drive
A friend has a G4, can that laptop run OS X 10.whatever? I know nothing about the Apple laptops...does OS X require an Intel based chip? (I assume a g$ is NOT Intel based.)
Suddenly yesterday when I powered mi iMac I had some horizontal green bars on the startup screen then it powered normally. But it happened two times, now every time I power on my iMac the screen stay black, and i can use my computer, everything else is working normally (i still can use Alfred to turn off my computer).
I already tried resetting the Command+Option+P+R, it didn't work. Also the Safe mode.
As the title states, I can no longer put my computer to sleep using the power button. I have to put it to sleep using the mouse. I miss the convenience of the power button. The window for energy saver is not like the display in support, it is missing the "Allow the power button to put the computer to sleep" option. Very strange. I am running an older desktop (2009) with Mavericks, fully updated. 10.9.4
I have a 2007 20 inch Intel core 2 duo iMac and an LG 46" LCD tv. I bought an HDMI cable and a Mini DVI to HDMI adapter but cannot get them to work together. Nothing happens when I click on detect displays in the system preferences.
Do I possibly have the wrong version on Mini DVI, for instance DVI-D instead of DVI-I?
This has been happening a lot lately. I've tried the Apple hardware test and it passed successfully. I reloaded Lion OS X but I still see an occasional problem with program freeze that I never saw before.
Hopefully someone can answer this simply enough, any help would be greatly appreciated. I'm looking to grab a couple used macs and just wondering if I can use the copy of Tiger i have already, the one that came with my Macbook.My question is about compatibility with other macs. I have the original disks that came with my Macbook Intel Core Duo, Mac OS X 10.4.6.) Will these discs possibly work with all intel-based Macbooks? What about with a desktop?2) Will it work on all Intel based systems,
When I turned on my 13 inch Macbook this morning I got a black screen with the message "No bootable disk, insert startup disk and press any key". This has never happened to me before and I am wondering what the cause is and how to avoid it in the future. I got the system to start by pressing and holding down the option key.
