Imac power switch

Just purchased a new iMac yesterday. Has anyone had problems when pressing the power switch and you hear the chime, screen flashes, then goes black?
It seems to only happen when I had it unplugged. After a few tries it powers up to the desktop.

Hello TM:
The chime (one) is normal. That indicates the Mac has successfully performed a start up self-test. The screen flash and the black screen is definitely not normal. I would contact Apple at once (store or Applecare) and request a replacement under warranty.

TS1367 New iMac Power Switch

Is there a power button on the iMac? Mine is not powering up when I plug in power cable.

Lacie D2 HD crashes iMac upon turning Lacie power switch off

I have a newish Lacie D2 external 1T hard drive (thunderbolt and USB 3 ports) attached via the thunderbolt port to my newest iMac.
All was working just fine until last month when, after ejecting the Lacie and then turning its power off at the Lacie power switch I noticed that my iMac (OS X 10.10.2) screen immediately went black and the iMac began its restart routine. I have tried both thunderbolt ports and the Lacie crashes the iMac consistently. The USB 3 port works just fine and does not crash the iMac.
I have run Disk Utility and it reports no problems. The files on the Lacie are fine and I can copy files to and from the Lacie as usual.
Suggestions???
Thanks in advance,
Bill..

Thankyou for the helpful and considered reply. Your suggestion that the Lacie drive circuitry has been damaged is the conclusion I'm coming to as well.
I have subsequent to this post tried a second Lacie external HD that uses the thunderbolt ports and experienced no problems upon powering of the external HD. This suggests that the crashing problem is localised to the problem Lacie drive. I was concerned that one or both of the iMac's thunderbolt ports may have been damaged.
As you suggest, I may have to purchase another external drive and copy all the contents from the failing Lacie before consigning it to the trash pack. For the moment I have implemented a very high tech solution: a piece of masking tape over the Lacie's thunderbolt port !!
Thankyou
Bill..

Turn on imac without power switch

Is there a way to turn on my imac without the power switch? This week I have had to push the button harder to turn on my imac. Today it won't turn on. The button doesn't feel right when I push it. I have a call into a mac repair guy but haven't heard back. I wish I could get into my computer now.
Is there a keyboard combination I could push?
There's a little hole on the back of the computer below the ac connection. Anyone know what that is for. I Bought the computer in 2007.
Thanks for any help you can give me.

mende1,
I went to an Apple reseller and they told me that my imac was something they could no longer get parts for. How odd I bought it in March 2007. My only option is find a used part and have it put in. I called Apple as I used to see if I could get the part number but they don-t have parts lists for that anymore. I found some parts of ebay that look like it but do not if it is for my computer. this is the link. http://www.ebay.com/itm/Apple-iMac-G5-17-iSight-WHITE-POWER-SWITCH-Board-Button- with-cable-593-0156-/120920713792?pt=LH_DefaultDomain_0&hash=item1c276faa40 I have no idea if you know about this kind of thing but you seem helpful and have answered so many posts I am trying. The problem is I have info fom my receipt that says my model is 2 ghz intel core duo and this ad says g5 and isight I don't see those numbers on my paperwork but I looked them up on wiki and it seems to be the right year. It is a white computer and it has the built in camera. Mayabe that is the isight. This seller has several ads for the same part number and another says 1.83 ghz and mine says 2 ghz on the receipt. When I used to turn on my computer I remember it saying outloud 1.83 ghz. Just wonderinf if you know. I know I have the white computer that they made from 2004 and 2006 and that it is 17 inches. It has EMC 2114 on the bottom which was the number I used to identify my computer on macfixit and they called it an imac 17 inch 2 ghz.

Intel iMac Power / Overheat issue?

Hi there,
I have an Intel iMac from 2006. About 2 years ago it started to just turn itself off randomly as if there was a power failure. When it does, the only way to power it back up is to switch it off at the plug, switch it back on and press the power button (strangely) twice. I have noticed it seems to be temperature related - when my iMac reaches around 78C (which I'm pretty sure it should be able to handle fine?) it tends to be in the danger zone and at any minute can switch itself off.
I've got around this by using smcFan Control - which thankfully displays the temperature in the menu bar meaning when I hit around 72C I can whack the fans up to full blast to keep the temperature down. Being a sound studio computer - the hum of the fans really isn't ideal, but it at least makes my computer usable. However, I'm currently in the middle of a big project on Logic and I've had to turn my room into a fridge (window open-more clothes on) to be able to work on it as all the processing involved heats it up to 75C+ in no time.
I was hoping someone could shed some light on this or at least tell me if I am right in thinking that 78C is nothing really and the iMac should deal with it easily.
I have seen tons of posts regarding the G5 iMac power problems and similar problems with the intel iMacs - I've done all the hardware resets (PRAM, SMC, PMU) as suggested in these forums but nothing has helped.
I have had the power supply changed in the past (before this problem arose) as one day it just went kaput. Don't know if that makes any difference but I'm pretty sure that the problem started a little while after the replacement was installed.
Thanks in advance!

External Power Switch

I just purchased a new 24SL410U TV for my severely handicapped daughter. Is it possible to turn on the TV with the remote or power button and then just turn the TV on and off via an external switch power switch and not have to touch the remote or power button again?

that is freaky. mine does a similar thing. i've observed my imac switch on all by itself. i turn it off in the morning when i leave for work and when i get back home in the evening i find the imac on but is in sleep mode. i've seen it happen right before my eyes once. but it doesn't happen all the time. maybe once to twice a week... trojan maybe? maybe we need an exorcist? it is definitely not the schedule/start or wakeup facility under preferences... energy saver... since i've never turned that
featuret on. although i do use the schedule to switch off my mac at 12 pm every weekday. maybe its another undocumented feature of mac leopard (among many other things). i sure never had this problem when i was using tiger.

Mac Pro turning on when switching on external power switch

Hi,
I have my studio including the Mac Pro behind a couple of power switches (Phonic power conditioners). Often, when I switch on the power switch that has the Mac connected to it, the Mac turns on without me having to press the Mac's own power button.
Why is this? Does the Mac get some kind of power surge when I turn on the power conditioner making it think there was a power outage?
The Mac is always fully shut down before I turn off the power switches.
"Restart automatically after a power failure" is turned off in the system preferences.
Best,
Maarten

Is there a way to adjust the bass and treble on my iMac Power PC sound system?

Is there a way to adjust the bass and treble on my iMac Power PC G5 sound system? It has a lot of volume (more than my JBL speakers).

No, but iTunes has an Equaliser that enables you to do that.

Creative Zen Micro 6GB/Problems with Power Switch and Firmw

The power switch on my Zen Micro has died. I can't turn it on or off unless I 'jump start' it from a USB cable and leave it alone to go into idle shutdown. I've had this player just three weeks and this is happened and frankly I'm disgusted. But wait, my story get's worse:
So before sending it back to Creative I thought that I should at least exhaust every possible cure. First on my list? A Firmware upgrade to v2.22.05. I downloaded the program and set about installing the new firmware but halfway through the process it hung and I had to end it prematurely. Now what I had was a ZM that apparently had v2.22.05 but was not being recognised at all by my computer. Media Explorer wasn't picking up on it and neither was WMP although strangely when I connect the device it's there in the Device Manager...
So, check back with the website and it said to download an update for Mediasource and that should solve the problem. Downloaded the patch but then realised that I hadn't installed Mediasource on my computer (can't remember why I didn't though). Went back to the downloads page and downloaded Mediasource. Tried to install it but I can't. The reason? because my computer isn't detecting the ZM and I can't install it until it recognises that it's there.
As a last resort I thought that I would try to use 'Rescue Mode'. Seemed simple enough, remove the battery and hold down the power switch. Then put the battery back in and wait for the rescue screen to come up. Seems easy enough. Oh wait, I don't have a working power switch.
What I do have though, is a small piece of plastic and metal that I can't turn on, can't turn off, can't put any songs on, can't listen to, can't fix and can't be bothered with. I have a ?60 paperweight.
Anyone at all have any idea what I should do? I just want to put it all in a box and send it back to Amazon with a request for a full refund or a threat to take them to the Small Claims Court.

Although a failed power switch is not unknown, I only recall seeing two or three other cases of this. It's not common.
If WMP isn't working with the device having v2 firmware something is wrong. Unfortunately this can be difficult to fix, but take a look here in the Zen FAQ at Nomadness.net.
MediaSource won't detect the player if there's some issue e.g. WMP0 not detecting it. You can of course also try installing Zen Micro Media Explorer (Creative Zen Micro Media Explorer Web Update to be specific) which has MTP support.
Are you are presumably under guarantee, and as you bought from an Internet store, it's best to return it direct to Creative. Contact Creative Support to arrange this.

HP Mini Netbook Power Switch

My sister is not able to power on her HP Mini 1010NR netbook. I was looking at the HP Mini 1000 Mainteance ans Service guild and could not find a part number for the replacement switch. Is there a parts manual and breakdown on this hardware area? The netbook is out of warrenty, but I would like to fix the issue with a replacement power switch.
Thanks for any help!
Update:
I found part #506336-001 to be a "on/off switch and USB card" through a google search, but the service manual only states it to be a USB board. Can anyone verifiy that tis is the correct part number?

I happen to own one of those.
There is no internal power unit, per se. Notebooks and netbooks have power circuitry that distribute and rectify power to various parts of the system board.
The greates likelihood is that your power adapter is faulty. Does the power led light up when it is plugged into the netbook?
Troubleshoot power/battery.

Software for Power Switch Control and One Key Recovery for Windows 8?

Hi. I have recently upgraded to windows 8 with a clean install. I was wondering if there is software to get the power switch control software back so I can set it to auto, turbo or cool because without it I think using the switch is useless. I also would like to know if there is a way to get one key recovery back.

I can't use the One Key Recovery of my Y2P anymore, as I decreased the size of the C partition in favour of increasing D:\Data
OKR won't even start anymore...
Any chance to get OKR working again if I make these partitions the same sizes?
Who has the exact partition sizes in MB of the Y2P 20266 with Samsung PM851 256 GB SSD?
0 1 MB NO_NAME unallocated
1 1000 MB WINRE_DRV NTFS
2 260 MB SYSTEM_DRV FAT32 (EFI)
3 1000 MB LRS_ESP FAT32
4 128 MB NO_NAME Other
5 ? GB C:\Windows8 NTFS
6 ? GB D:\Data NTFS
7 14135 MB PBR_DRV NTFS Recovery
8 327 kB NO_NAME Unallocated
Data is backupped daily and I already have a full system backup together with a bootable USB stick that has been tested.
But I like to make sure I can reinstall Windows in the future..

HI .. I have a new macmini 2.5 Ghz 10.7.3 Lion, had a problem today ,it froze so I could not shut down using mouse or tablet. used the power switch, when I tried to restart I got audible 'beeps' from it.

HI ....I have a new macmini 2.5 Ghz 10.7.3 Lion, had a problem today ,it froze so I could not shut down using mouse or tablet pen. used the power switch, when I tried to restart I got audible 'beeps' from it. I managed to restart it but kept getting a message come up on one ot the dual screens ' restart using the power swich to turn it off , then press it again to restart.'
This worked okay , but now it just keeps freezing whenever I start it up. I thought the issue could be my old Epson Expression 1680 scanner not being compatible , so I have unplugged it. I also had a look at the new memory I installed when I got it, but this seems not be the problem.
It is connected up to an Eizo Flexscan S2231W using a cable straight into the HDMI input , the other monitor is a small Acer using the VGA into Thunderbolt port.
When I turn the Eizo screen on first and then press the power button on the mac-mini, I hear the chime then the screen flahes the 'Digital no signal' message on and off for about 30 seconds , then the monitor comes on as normal. But it is still freezing up on me after using it for a while and I am having to use the power switch button to turn it off again.
Can anyone help please.

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

Can i take apart the imac power cord to put it through a hole in my desk. I'm able to get the ring off, but dont want take the housing off incase it breaks

can i take apart the imac power cord to put it through a hole in my desk. I'm able to get the ring off, but dont want take the housing off incase it breaks

I hear you. The reason I asked is that on the computer end of the cable, I took the ring off and it looks like there are some clasps around the housing, so I was wondering if these were for the purpose of threading the the cable. I will try and get some pictures. The drill is charging, however!!
Thanks
