1.turn into black screen after running for about 15 mins, but the system is still running because the keyboard is still functional. After reboot, i record the log as below, it shows that it is a GPU Panic.
2. display would not turn on after pressing the power button but can still hear the apple start up chime and the system keep running with the screen off.
3. after erased the hard drive and re-installed Mavericks. Under a new installed system, it can run normally for about 1 day, after that especially after a shut down or restart, the problems above came back.
I am currently working in Thailand but I have no plan to go back to the US in a short period of time. I brought the laptop to the local apple service, they said it is certainly the logic board or GPU failure and the parts need to be replaced. The cost of the replacement is around half of the price that I paid for this laptop.
I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

Just got a replacement imac 27 stock C2D yesterday for a defective one I had earlier, however, I couldn't get this new one to turn on till just a few hours ago. I just figured out the power button needs quite of bit of pressure to turn on. Seemingly just pressing it until it clicks isn't enough. Should this be looked at or is this normal?
I have a macbook pro, bought it May last year(2008). I don't know much about computers, but I loved the transition between pc and mac, had no trouble with it, loved to work with it, until now. I had noticed it became slower like 3 weeks ago, and a week ago, it started to freeze up on me followed by a message that said please restart your computer by pressing the power button and the screen becomes dark. When I try to restart it again, it takes a while because it shuts down again and again, until the 10th time it works. The store told me to clean intall, which I did yesterday, it seemed to have worked, it was faster for sure, but today it happened again, 3 times! Has this happened to anyone? Does somebody know what to do?
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.
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.

My MacBook pro (15" unibody, non-removable battery) will not turn on. The battery claims to be fully charged. The computer will not respond to the power button in any way. I had turned it on previously by draining the battery completely of any charge (draining power, then pressing and holding down power button for 60 seconds). When this occurred the computer booted up and ran fine. However, when I closed the lid, it turned off immediately, never to return. I'm wondering if this is a problem with the battery, or if it's a problem with the logic board.
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.
The most recent log in the system diagnostics is titled:
I have a G5 dual 1.8 power PC...Bought some ram put it in & booted up. Then a red light came on the logic board behind the power button. The machine wouldn't turn on....I called apple care & we rearranged the ram, now the red light is gone but my system still won't boot up. The white power light blinks every few seconds... the apple store told me sorry can't help because your machine is vintage. Even if my logic board is fried is there a place to buy one on the cheap?
I 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.
I added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.
I'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.
I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.Unfortunately my cats like to touch the keyboard, thus waking up my Mac.Is it possible to wake the mac only by pressing the power button?
I have brought the 21,5" iMac 1 week ago. I just chosed the preconfigured model. But i have had some problems with it.When the computer has been to sleep for some hours, it wont wake up with click on keyboard or on the mouse. I will have to use the powerbutton, where the computer then comes with a error, but it starts up.
This morning when the power button is pushed, nothing happens at all. The button does not light up. The computer does not start.I checked the power cable. I took it out of the computer and put it back in. (I did note that the plug looks a bit darkened but it does not smell burnt.) I tried it in a different outlet. Same thing. It won't turn on.I can't recall if this iMac is a G3 or G4 and I can't find my documentation to let you know. But I don't know that it matters which G it is. It is the old special edition grey iMac and has been working for us for many years.Is this the end for this iMac? Could it be something that is simple to fix?
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 left my iMac on overnight last night to finish downloading some stuff. I woke up and all our clocks are flashing, so we must've had a blackout. Anyway, I went to check the progress of my downloads, and the iMac was off. I pushed the power button and nothing happened. No fan noise, HDD noise, nothing. I've been trying for almost two hours now and nothing is working.
my G5 was in sleep mode during 2 power outages. She will not turn back on, have tried unplgging, wait then replugging and turning powerstrip back on. Also tried holding down command,option, p & r keys along w/ powerbutton..I'm on my kindle fire rt now, but definitely need my Mac back up.
I cannot get my macbook pro to switch on.when it is not plugged as I press the power button nothing happens, when the computer is power plugged, it gives me the white blackground with the apple centered and the loading button below but it keeps loading forever left it as for 4 hours and still nothing. I have try to reset the SMC but didn't change much, now instead of the apple logo I get a circle crossed My macbook is 1 year and 4months?
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?

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 have just shipped my Mac Mini to its new home and I've had reports that the panic error is appearing on boot up: "You need to restart your computer. Hold down the power button for several seconds or press the Restart Button." This screen appears on the blue window just after the grey apple screen has disappeared and does not get as far as the desktop at the same point each time. We have tried to reinstall mac OS from the original install disk but holding the "C" Key or the "Option" Key down on restart doesn't boot from disc. Is there a way you can view the Kernel Panic log before you boot into Mac OS so we can try and pin point the source of this problem. I'm wondering if this could have been the result of the shipping that has caused some hardware to come loose.
