IMac (Intel) :: Cannot Put To Sleep Using Power Button Since Mavericks Upgrade 10.9.4

Aug 22, 2014

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

IMac (Intel) :: Will Not Come Out Of Sleep Mode On OS X Mavericks (10.9.4)

Aug 31, 2014

My iMac will not come out of sleep mode and if it does it takes a really long time to do so. I've looked at several things in other forums and it seems to be a Maverick issue. However it only started about a month ago and most people have had this issue since the release of Maverick. I also read to use the bluetooth keyboard and mouse instead of a USB one. That also did not fix the problem. So I am at a standstill ...

Intel Mac :: Power Button Won't Work On It

Apr 14, 2012

I turn off Imac, using apple menu. Sometimes the power button will work to turn it on, other times it won't. Been to 2 authorized dealers, they can't find problem. Sometimes jiggling or shaking computer will allow me to start using power button. Sometimes I open up case, plug and unplug everything, and then power button will work. Never know when it will work or not. Power button has had continuity check. It checks fine. Power plug is fine, outlet is fine.

IMac PPC :: G3 Will Not Start Up And Nothing Happens By Pushing Power Button?

Apr 9, 2012

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?

IMac :: 27" Power Button Needs Pressure To Turn On?

Nov 30, 2009

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?

OS X :: Uninterruptible Power Supply (UPS) - IMac And Sleep Mode?

Jul 22, 2009

First, sorry for the longer post - I have to explain everything. I just bought a 24-inch iMac, Mac OS X 10.5.7, 2.66 GHz Intel Core 2 Duo, 4GB, 1067 MHz DDR3. I also just bought an uninterruptible power supply (UPS) from CyberPower. Everything's great, but I still have this one question which is bugging me. What happens when my iMac is in sleep mode and the power goes out? I have set the settings so that my iMac shuts down after 10 minutes of "battery" (UPS) usage, but I am not sure if it will do that when in sleep mode? The UPS is connected to my iMac via USB cable so that they communicate to each other in the case of the power outage, etc. This is what somebody wrote elsewhere on this topic: "Using the Deep Sleep widget, I've worked around this issue: I changed the default sleep behavior to Safe Sleep (hibernation+sleep).When I'm on the grid, my computer will now safe sleep after 3 hours of non-use. If I go off the grid and onto UPS while the MP is awake, the Energy Saver preferences will safe sleep after 1 minute. If for some reason this doesn't occur, Energy Saver will invoke a shut down after 5 minutes. If I go off the grid and onto UPS while the MP is safe sleeping, no big deal since contents are written to the HDD and RAM with this configuration."

I've downloaded the Deep Sleep widget and am using it now. Obviously, the user up there is using a MacPro, and not an iMac, but it should work the same. So, I am not concerned about losing data, and blah, blah, blah... what I am most concerned about is my iMac not working properly because it wasn't shut down properly. I know that there is a very low risk of this happening, but I've spent big bucks on this iMac and I want to make sure that it is shut down properly 100% of the time, if I can help it. If my iMac loses power when in deep sleep, will it be ok? Obviously, I am still using the UPS in deep sleep, but that UPS (battery) power will not last long and will shut down. I am going to turn my iMac off when I don't plan on using it for several days, but if I'm just out and about and the power goes out and my iMac is in deep sleep, will it be ok with the power going off? I contacted CyberPower and this is what they had to say after a long back-and-forth. "You will want to use the deepsleep tool. I had the belief that sleep was the same as windows hibernation where everything is saved to disk. Since deepsleep will save to the hard disk, you would not lose anything when the power is lost when the battery runs out." Despite all of this, I wanted to hear what everyone else thinks about this, especially those of you who might have experience with this kind of stuff. What do the rest of you do when it comes to UPS, etc.?

PowerPC :: IBook G4 - When I Press Power Button, Power Fan Comes On, But No Picture Shows

Feb 10, 2008

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.

Power Mac G5 :: Won't Boot Up Blinking Power Button After Adding Ram

Dec 6, 2007

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.

Power Mac G5 :: Dual 1.8 Not Booting When Pressing The Power Button

Dec 13, 2007

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.

PowerPC :: Making Power Button Shut Power Mac Off?

Oct 7, 2006

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.
