MacBook Pro :: Unable To Power Up / Computer Suddenly Turn Off
Aug 20, 2014
my Macbook Pro is not powering up, Yesterday I connected a camera that has the USB cable with the little transformer. And the Computer suddenly turn off!  It´s not working at all... I really don´t know what happened..These are some of the characteristics of the problem:Â
1) Not even the battery Light its on when I press the Power button.
2) Not even the Light in front of the Mac is on when I press the Power button.
3) There is not even a sound of the cooler fan or anything.
4) When I connect a the power cable the first 10 seconds the light of the cable is off... Then it appears a little "Orange intermittent" light but nothing more happens.Â
I tried the "search" box before making this thread. Would like to know if the power supply from a 2008 MacPro work on a 2006 MacPro. If anyone has tried this? My 2006 MacPro shut down suddenly and would not turn on. I use an APC UPS plugged on a power surge outlet. The Mac technician who examined the unit suspected it might be the power supply but Apple may not have in stock the power supply for the Ist Gen MacPro.
So I'm having issues with the computer not waking up in the morning. I guess it goes into a deep sleep of some sort and I have to hold the power button twice to turn it on, and get greeted with a computer experienced a problem message on login.Â
The most recent log in the system diagnostics is titled:
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 just aquired a PowerBook G4 (500Mhz) and it is dead. It will not turn on no matter what I try and when I plug in the power adaptor it glows a bright orange (almost red)...what does that mean?
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?

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.
My MacBook suddenly turned off. There was a click sound and then nothing. I have tried to restart it but nothing happens. No sound no lights. It is plugged in and the power cord shows green. I have not damaged it in any way.....
I was working when both the charger light and computer went off suddenly. I did the same click sound it does when holding the power button to force it to shut off. Since then its dead to the point that when I connect the charger the little orange/green light doesn't turn on nor does the computer nor does the battery meter on the side of the computer. Battery was perfectly good holding charge and it was full.

I got my Macbook Pro only 6 months ago, and supposedly, it is a really strong and good computer: 2GHz Intel Core i7 with Version Mac OS X 10.6.8.
A couple of times a week the screen suddenly turns blue. I can't really figure out a pattern as to when it does it. Often, I'll be switching between word and a pdf and then it just suddenly turns blue and I can't use any bottons. I just recently discovered that if I simply close the Macbook and open it up again, then I'll get back to where I was before it turned blue. In this way, I can make the computer 'wake up' by closing and opening it once or twice. Also, I can force the computer to shut down by holding the switch-off botton down for a while.Â
However, something is obviosly wrong, and it is anoying and also, I would like to find out if it is a hardware problem before it's too late to get it fixed within the hardware-protection period of 1 year after purchase.Â
I just formatted the hard drive a couple of days ago and re-installed everything, but it still happens. Also, I tried to do the 'hold down option-command-R-P'-thing but it hasn't solved the problem.Â

I keep having the screen turn blue and then suddenly go back to normal. It's a quick flash, totally random, repetitive during operation, no noises, and nothing else is interrupted. It does not restart, log off, or try to. Is it about to die?
Tried to restart didn't work. Light is on, but nothing makes noise or anyhting. Been charging it for hours so it has power. Tested the chord on my ther computer and it worked
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 hear the computer physically turn on, but a blank screen remains. I recently purchased a new battery for the computer for the battery status read replace soon about a week ago. I sense that maybe there is a shortage in the wiring that connects what shows on the screen to the computer, but I'm not completely sure.
I've had my macbook for about 15 months. i noticed a while ago it had trouble turning off completely when running only on the battery. then a few weeks ago it shut itself off and wouldn't start up again. the power cord indicator was orange, but nothing worked. ordered a new battery, that didn't help. tried a different power cord - nada. i took it in to an apple repair shop and they said something about the internal power connector (i'm not a techy) and took 2 weeks to repair. i've had it back 3 weeks now and the same thing has happened. only this time there is no indicator light on any of the power adapters. and my partially charged batteries do not work on their own either.
any ideas? i don't want to keep fixing the same thing and every few weeks it keeps breaking again. i mean, what's the point in having the computer then, right??
I was charging my macbook. It was charging when I left, upon my return, after about 30 minutes, I found that the light was no longer green. There was no light on at all. I tried restarting multiple times. There are no stuck prongs in my power cord. I tried different outlets. I tested the outlet to verify it worked. My computer will charge fine with other power cords, but just not the one I want it to use? Is there anything else I can try before purchasing a new cord?
I've noticed recently that my screen brightness will suddenly increase or decrease by itself. When I press one of the control buttons it indicates that it is 3 or 4 steps higher or lower (obviously allowing for the fact that pressing a control button moves you one step anyway!) I have the 1.8 SDD. I love the machine....but anyone have any ideas about this. It only happens under battery power.
i just got my new imac 2 days ago. I was wondering is there another to turn on the power without pressing the power from button? (cuz i remember u can power on from the keyboard b4)
I have a white 2008 model MacBook. Due to some unfortunate tampering with the circuits under the right command key on the built in keyboard, a lot of the keys and the power button are now effectively dead. I'be ordered a replacement top case, but was wondering if I could, in the meanwhile, somehow turn the laptop on. I'd prefer to do this without opening it up, though I could if that's the only way. Â
I read in another thread, can't find the link now, that disconnecting the battery, connecting mains, then connecting the battery would turn it on, but that doesn't seem to work for me.

I got alerted that I had the flashback virus and was told to download SOPHOS ant-virus software. I did this and did a scan once the scan had found the vrius I cleared it and ended the scan. I then turned off my MacBook and it won't turn back on again. It comes up with the apple symbol and that start up noise but it does not progress from there. The apple symbol turns into and error symbol and then dissapers. My computer then stays a grey colour.
I used my laptop at work. when i got home, i plugged it in to charge, it was at 22% and it turned off after i checked facebook. i thought it was the outlet itself, but it seemed to work when i charged my phone. now my computer will not turn on and the adapter blinks instead of a solid color.
