Can only restart Mac by pushing the power button

I have a 2010 27" iMac with the i7 chip and 8GB RAM. For the past week various programs are freezing and the only way to power down it to press the restart button.
I have deleted the plist for: Safari, iPhoto 11 and the dock.
I am new to Mac (from the windows world) and have no idea why this is happening.
Last night the dock froze so I couldn't click on anything on the dock.
I installed boot camp and attached a windows my book to a USB hub as part of the windows process. That didnt seem to cause the problem (I just want to give you the information that it is there).
Restarting completes fine but once there is a freeze a hard reboot is my only way out.
any help will be appreciated.

OK that's good news, it means it's a software problem that is in your user account. Now all you have to do is track it down. The first thing I'd try is restarting the computer in Safe Mode. This will clear some of the caches, what can occur is some may become corrupt. After starting in Safe Mode restart as you normally do and see how it acts. If the problem persists there are other suggestions.
If the problem started after installing Boot Camp it's possible that is where the problem is. If you have Boot Camp running on your computer you have to install Windows 7 on the iMac. Trying to run Windows remotely is a recipe for trouble, that much I know. If we track it down to a Boot Camp forum then I'm going to refer you to the Boot Camp forums as I don't really know that because I don't run Windows.

How can i restart my phone if the power button is not working?

My power button is not working and my phone freezes every now and them. I read I should restart it. Is there another way to restart it without using the power button?
Also, I use the on-screen assistance icon but it does not have a power off option.

That's correct. Because how would you turn it back on again if the screen was off and your power button was on the screen?
Yo need to fix the button, or try letting the iPhone die out completely, then connect it to power and after it's charged for a while, see what happens when you press the Home button.

My MacBook pro is frozen and I can't restart, even by using the power button or control command

Hi- my MacBook pro froze about an hour ago and I've been unable to reboot it. Any suggestions? I've tried the power button, control + command + restart, erc ad none of them do anything.

Hold down the power button for 6-7 seconds. It will power off, then click the power button to turn on again.

(Assuming you don't have a firmware boot lock set)
First easy step...
1. Shut down the computer if it's on (hold the power button down... until it shuts off)
2. Press the power button
3. Immediately press AND hold the Option key ASAP
Hold until drive option images appear in a single row across the screen. Typically most people running 10.7 or 10.8 will see 2 drive options to boot from: the main volume they usually boot from, and a recovery volume. If your main volume pops up. Use the cursor or arrow keys to highlight/select the main volume and press enter. That should boot your main volume. Let me know what you get from this point... I'll give you more as you go along.

Push the power button to restart system

In the last 2 hours I keep getting the pop up screen "Push the power button to restart your system" I was copy files from a segate drive to my Time Capsule. First I thought I wa copying to many files at a time and started to copy one at a time and I still get the pop up. Your Thoughts?

Hi, and welcome to the forums.
Are you sure that's exactly what it said?
That sounds suspiciously like the message you get (in several languages) saying you need to restart your system, and it's a result of a *Kernel Panic.*
If so, they are usually caused by hardware problems, but can be software.
Disconnect all peripherals, except keyboard and mouse. Reconnect one at a time to see if you can find the culprit.
If that's no help, run the Apple Hardware Test, from the separate disc that came with your Mac.

My mac pro wont start. I push the power button and I get a click sound. A few seconds later another click sound and that it.

My mac pro wont start. I push the power button and I get a click sound. A few seconds later another click sound and that it. I've tried different power plugs. Going direct into the wall, through a power strip. By iteslf, with other devices plugged in. I removed hard drives, and some RAM, and nothing. Sometimes it would not turn on, and then some minutes later it works. So its was sparatic, but now its been the same situation for three days where it wont turn on.
I'm guessing power supply, but I wanted to see if anyone had a similar expereince and what the solution was, before I drag this beast to my local Apple store and have them look at it. Its a real pain to get it there and back and I want to be armed with some info for them. I already dragged this to them when it first started to do this, and of course it started up just fine for them. And you know if it works for the Genius then theres nothing wrong with. No matter what you explain to them.
I figure if anyone had a the same problem and was able to resolve it, I can relate that experience to the Genius even if it start up for them.
Thanks

Try a SMC Reset using the extended method:
Remove the AC power cord.
Press the power-on button. [This drains the stored charge from the power supply]
wait a quarter minute.
Restore the power cord, being certain to JAM it into the socket, as the big block of rubber inhibits proper seating.
wait a quarter minute
attempt to power on.
If no joy, examine the button battery half-hidden behind the graphics card. Remove it to measure the Voltage. A new battery should not cost over US$5, and measures a little over 3 Volts. BR-2032 is used in garage door opener controls and car door locks controls. The geeks at Radio Shack can measure it for you.

My computer shuts down after 45 seconds from when I push the power button. Anyone have an idea why?

After pushing and holding the power button on my Mac the apple screen comes on and after a few seconds there is a loading bar that tries to load something for a few seconds then it shuts down. I would say it is approximately 45-50 seconds after pushing the power button. Power comes on then shuts right off. This all originated when I tries to log in as a different user. It froze for a while, then I shut down the computer with the power button. Because I couldn't so it from the apple icon on the desk top

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

I'm getting kernel panics each day as I shut down, the message of restarting by holding down the power button appears on the screen - it began about a month ago and. Do you have any ideas of how to solve the problem?

I'm getting kernel panics each day as I shut down, the message of restarting by holding down the power button appears on the screen - it began about a month ago and. Do you have any ideas of how to solve the problem? I've copied the logs that I found for each kernel panic that still have the message logged. Please help if you can, I have read some of the other comments and perhaps it has something to do with my anti-virus software being on at start up. I have copied the log here. Any advice will be welcome.

Immediate suspects are the additions you added to you rsystem that installed kexts (drivers). From above,
com.intego.iokit.VBX6NKE            1

com.globaldelight.driver.BoomDevice            1.1
com.huawei.driver.HuaweiDataCardACMData            4.2
Two experiments you can try.
1. Boot in safe mode and see if you can shut down normally. All thise additions won't be running in safe mode so this test would indicate it is one of them causing the problem.
2. Uninstall all the intego VirusBarrier stuff. That's my first guess and the troublemaker.

"please restart your computer from the power button" message

Hi,
I woke up yesterday and the computer´s fans where running like crazy. Everything was frozen so I pushed the power button in for a few seconds and restarted the computer. When it came up I used it for like half an hour and it froze again. I did the same thing because the keyboard was´t working eather.
It did that a couple of more times during the day. So I started shutting it down when I wasn´t using it.
Last night, the last time it happened, I was checking my email and this message came on full screen in 4 languages.
*"Please restart you computer by pressing the power button for a few seconds"*
Or something very similar to this.
I did it and I haven´t turn it on since then.
In the middle of all this I checked the disk and it said is was fine, the permissions as well. I don´t know if it means something thought.
I don´t know if it´s a hardware or software issue, any ideas?
Thanks!!!!

Hi japamac,
This morning the computer froze again... no messages but I had to restart it.
So, I did the things you pointed:
+-Boot to the OS X Install disc, in the second window after the language selection, from the Menu bar, select Utilities/Disk utility, and use that to "Repair Disk" on your hard drive.+
I did this and the disk was fine... it said something like +nothing to repair+
+-In the original software discs is one with the Apple Hardware test.+
+Boot to that disc and run the extended hardware test to verify system performance.+
Did the extensive test and as soon as the dialog box came up, under test results next to MEMORY, it said: error detected at startup. Then It went throughout the devises and everything passed (including the MEMORY) but there was an error code *post/0/2048 DIMMO/J11*
So, I tried to download Rember but it`s for 10.5 and higher... I´m still using 10.4... is there a similar software for my OS?
Thanks for your help!

X1 Carbon Touch: have to push the power button twice to boot the system

This is what always happened when I booted up the computer:
First time when I pressed the power button, the computer was on for just 2-3 seconds showing the "Lenovo" logo, and then automatically went back to power-off with nothing happened further.
And then I pressed the power button again, the computer booted and loaded the operating system without any problem.
Even though I'm able to start the computer in this way eventually, it is very annoying. It happens every time when I cold started the system (no such a problem if I simply restart the computer). Anyone knows why I have to push the power button twice to boot the system? I suspect it's something related to the rapid start technology, but cannot locate the exact reason. Anyone else has the similar problem? I have a Windows 8.1 now, but the problem existed when I was still using Windows 8. After I upgraded to 8.1, the problem still exists.

Batteries

I pushed the power button and now the screen won't light up and the keyboard lights a on

Now that you mentioned it, that might be the source of the problem. Something was definitely wrong with my graphics card before the incident happened. You mean that particular batch of graphics cards had some inherent issues, right? I went to the genius bar, and the 'genius' there, without trying to diagnose the problem properly, just adviced me to buy a new mbp! He said Apple will no longer try to fix or touch macs older than 5 yrs. Mine is 5.5 yrs old...
