I was playing around with my mac g4 logic board... ( yes, i know... ) anyways, i press the power, the light turns on, and the fan spinns up then everything just turns off... http://docs.info.apple.com/article.html?artnum=95035
^ my tower, (agp graphics, ftw)
I've tried turning it ff and on via the power button several times, but it always goes back to the white screen.

MacBook Pro (13-inch Mid 2010)
Had (used) iBook G4 several months now & thoroughly enjoy it, even tho' I live in the sticks where there's no hi-speed/wireless available; I connect to internet & power, which is fine.
This weekend I went to turn off my iBook & it wouldn't turn off. It's now permanently on, with opening info barely visible (like I need to click on F2 to brighten up, except nothing happens).
Currently using my "back up" computer, my iMac Grape, which is pretty much an antique by now.
I have a problem with my 17'' MBP unibody:
1) Bluetooth is ON:
I can't turn it off. The checkbox is inactive.
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.
I was using my friend's MacBook pro last night and the screen suddenly won't work. I will pay for the repair but is there anything that I can do at home to fix it? I wanted to remove the battery like I do with my own laptop(pc) which usually works to reboot or fix a problem but there is not way to remove the Mac's battery )?
Info:
MacBook Pro
When I turn on the power, it doesn't work but the question mark appears. What am I supposed to do? (question mark inside of a file mark)

my laptop (macbook pro) doesn't turn on, because the battery doesn't work (may be because of moisture), and the 7 battery lights on the left side are off, and when I plug the charger in, the light on the magnetic socket turns on so dim ..

View 3 Replies View RelatedMy MBP won't turn on properly. Every time I press the power button the computer turns on but instantly goes into sleep mode. I have tried restarting a lot of times and I have let it stay on in sleep mode for a while, nothing seems to work. I have had the problem occassionally where my MBP won't wake from sleep but it usually works after I restart it. Is there anything I can do to get my MBP working properly?

View 6 Replies View RelatedI have read over and over how many users have sleeping issue problems. The way I look at it is just leave your computer on. Mine runs 24 hrs. a day 365 days a year. I never put it to sleep. Yes you well save a little hydro but your problems will go away. When I am not sitting at the computer I turn off the monitor. I have done this for the last 10 years on the PC and since Feb.14 on my new MacPro without any issues. So in my opinion, leave your Macs on and turn off your monitors when not in use.
View 5 Replies View RelatedI just bought a new 24" HP LP2475w display that I'll use as my primary monitor.
I'll keep my old 17" ACD as a second monitor, but I won't need to use it that much and would prefer to power it off when it's not in use.
Is there a way to do that? (I touched the power button for almost 15 seconds and it didn't turn off.)
have a new 24" imac, about a year old and the fan came on after it got very hot, only browsing the web) and now it wont turn off!, switched off mac last night, turned it on again this morning and fan is spinning like a goodun.

View 2 Replies View RelatedI have just come back home and turned on my macbook 2007 model. I was using it fine just 5 minues ago. Then I shut it down. Now It will not turn on. I've had 2 hard drives die before (made clicking noises). My 3rd drive was purchased 1 month ago. Is there any way to determine what's wrong? There have been no drops or obvious physical damages. It just will not turn on. There's no signs/lights or error messages. (the battery has charge and the power cord is plugged in) [i dont have apple care]
View 1 Replies View RelatedWell I bought a new 15" MacBook Pro in January 2009. And for the most part it's worked like a dream.
Last night I was using it as usual, when suddenly I heard a very brief, quiet internal noise and the computer turned off immediately. It was as if some vital component inside the computer said "screw this" and stopped working.
Now when I press the power button, absolutely nothing happens. I've tried using battery only, AC only, and both. Nothing works.
I've scheduled a phone call with Apple support, but until then. I wasn't doing anything out of the ordinary when this happened, just browsing the web.
I have a Apple Airport Extreme n operating in Bridge mode behind a Belking g router with the DMZ open for my Xbox 360 IP address only.
How do I turn on DMZ for the Xbox 360 IP thru the Airport Extreme.
Where the internet tells me to do it on the INternet tab I do not see "Default Gateway" to enter the Xbox 360 IP.
So yesterday my keyboards didn't want to work. So I reinstalled everything again and then it worked, but the letter O was showing only capatalized and when I pressed shift it would give the letter O and when I tried to type a question mark or quotation marks using the shift keys the windows would minimize.
Then, researching on what to do next I found that some people found reseting the RAM should help. So I did, I removed the batteries, held down the power button for 5 sec..and so on. After that my MacBook didn't want to turn on. I've tried everything on the Apple Support page, but still nothing.I was wondering if anyone had this problem before and what to do.
After some super quick advice!
Got in to the studio today to find my main Macpro (Xeon 2007 model) dead.
When I turn it on it powers up, but does not make any noise (No beeps, no startup), does not display anything on the monitor, the hard drive spins up but not long enough to actualy do anything - I think its just the sound of power getting to it.
Iv removed the hard drive, and all ram (apart from a 1GB), and all cables apart from the power and the same thing happens.
I have a 15" MacBook Pro (early 2008) and it recently took about a 2ft light drop (onto my carpet at that). It Completely shut off and wont turn on AT ALL. When i plug my charger in it`ll take a few seconds before light on the magsafe connector light up (green). im pretty sure it isnt the DC Board (since its been recently replaced with a newer one). can it be my logic board?
View 4 Replies View RelatedI have a Mac Pro 8 core that is almost 2 years old. Still running Leopard and 10.6 I believe.
This morning all worked great, and after a lunch break the 30" Apple monitor won't turn on. The power lights on the monitor. We substituted an older 22" we have and that won't work as well.
We tried both video inputs on the back on the computer and still nothing.
When we turn on the computer we hear the Apple signature sound and even though there is no visual on the monitor, this computer has a QuicKey keystroke to shut down the computer and this works.
Is this a graphics card failure?
My MacBook Pro 13" MB990 turned itself off yesterday and I haven't been able to get it turn back on. I have done some searching around the forum and haven't managed to find any solutions.The MagSafe adapter is definitely working. The battery indicator shows 7 of the 8 LEDs lit and the 8th flashing, suggesting that the battery is charging. The LED on the MagSafe is glowing orange.I have also tried doing an SMC reset pressing the left Shift-Control-Option and Power Button combination. When I do this the LED on the MagSafe changes to green for a couple seconds and then switches back to orange (I'm assuming this means that the SMC reset has worked) but pressing the power button still does nothing.

Recently, I was using my powermac (About 1-2 weeks ago) and I went on vacation. I came back and it won't turn on. Everything's plugged in, and the power buttons and lights on the mobo light up. I can hear the HD spin up, and begin to read. But, I don't get any video. I've read that it could be the battery and so i replaced it, but it still won't turn on. I've reset the CUDA, installed different RAM, took out expansion cards, but it still won't turn on. Also, when I press the power button it immediately shuts off, which it never used to do. I usually have to wait at least 3-4 seconds of holding it down.

It worked fine last time I used it, shut down properly and now nothing.
View 4 Replies View RelatedThis just started: I woke the machine from sleep and the fan is on full blast and stays on even after sleep and/or reboot. I tried leaving the machine off and unplugged for a while but still fan is on full. The machine is completely cool and activity is 0%. Everything works fine, the only problem is the fan (noise).
