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

Can i use an external power supply to power second graphics card?

hello. i currently have an ATI 5870 in my 2010 Mac Pro. I want to throw a Quadro 4000 in there as well, but i need one more 6-pin power cable. can i plop the quadro into the second PCI slot, buy a PC desktop power supply and just let it sit on the outside next to my Mac Pro, and then just run a 6-pin power cable from the power supply into the Quadro? i realize that the Mac Pro door would could not be placed back on...but i could figure out some way to cover up the opening so that dust doesn't enter.
would this work? anyone tried?

Hi,
Just want to ask a question that is not clear on everything that I have read. If you don't switch off the external power what do you take the risk for? Could you burn something or the card will just continue to work (spin the fan) after you turn off the Mac Pro? Where is the dangerous part?
Thanks!

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..

Powering down display with external power supply

I am using a 23" display with an old PowerMac G4 from 1998 with an upgraded video card and external power supply.
Is there any way to power off the monitor without powering down the computer? Ideally I'd like this to happen automatically based on my system prefs, but apparently the external power supply precludes this.
As a "workaround", I've created a screen saver that displays a black image. Does this actually save any energy and/or extend the life of my display?
Thanks,
- Michael

Hi Michael,
Welcome to the discussions.
You can install an on-off switch on the power lead to the external power supply (actually, it's safer to have a qualified electrician do this, as you are dealing with a mains power supply). I have this system for my ADC 15" Display, and it works fine.
A black screen saver will not extend the life of your monitor. Screen savers were meant to mitigate the "burn in" effect that happens with CRT displays (and which doesn't happen with LCD displays). If the display is still on, the backlights will still be functioning and they are the finite life component of the LCD display that you need to look after. Also, because the LCD's themselves use so little energy, there will not be much energy saving.
It's more appropriate to "sleep" the display. You can do this (via Energy saver settings in System Preferences) without having to "sleep" the entire computer. This will turn off the backlights and significantly extend the life of the display.
(I'm presuming you are using OS X - you haven't supplied any details regarding your system. :))
Cheers!

IPod won't pause when external power removed

I use my IPod Nano to listen to audio books in my car and I have a 12 VDC charger connected to it. The 12 VDC is turned off when the car is shutoff. Older generation IPod would pause when the external power was shutoff but the new IPod doesn't. Any body know for a solution to this? I keep losing my place in the audio book which is a huge pain. Thanks.

I found a page at http://www.allpinouts.org/index.php/Apple_iPod,_iPad_and_iPhone_dock and it has a section that states:
1MOhm - Belkin auto adaptor, iPod shuts down automatically when power disconnected Connecting pin 21 to ground with a 1MOhm resistor does stop the ipod when power (i.e. Firewire-12V) is cut. Looks to be that when this pin is grounded it closes a switch so that on loss of power the Ipod shuts off. Dock has the same Resistor.
This connects to pin 21. So it appears that there may be Belkin Auto Adapters available for the new 30 pin dock connector that will allow to pause the IPod when Power is removed.

Power switch circuit for 13" MacBook

I replaced the water damaged keyboard on my white 13" MacBook 6.1, which now works except for the power switch and Keycaps light. I think what happened when troubleshooting, I jumpered the 2 MLB contacts to bypass the power switch and may have made contact with another trace that may have damaged a diode or transistor in that circuit. Plus, I think that the fact that the Keycaps light doesn't work indicates that supply voltage going to the power switch in missing, if that is where the Keycaps LED gets its power. Jumpering the contacts is still the only way to power it up. If anyone has the circuit diagram of this part of the MLB or knows the solution I would appreciate the information. My last resort is to wire an external switch to the contacts and mount it somewhere on the side of the laptop. Thanks for any help.

The magsafe adaptor does have its own circuitboard, so it could be an isolated failure of the DC board.
iFixit has the instructions to replace the board.
powerbookmedic.com has the parts, generally less than $50 but depends on your model. Make sure you get the right model!
http://www.powerbookmedic.com/Magsafe-DC-IN-Board-for-MacBook-Pro-15-Unibody-p-1 7273.html
Personally, I would take it to the Apple store and try out one of their power supplies, just to make sure that your AC adaptor is not the cause.

How do I get the backlight to stay on, when connected to charger / external power ?

Hi,
Is there a way of setting the backlight on my 8900 Curve so that when it is connected to the USB or Mains charger,
( and therefore not draining the battery ) the backlight stays on ?
I can only find settings in Options / Screen/Keyboard, which I have set to leave the backlight on for 90 seconds, and dim automatically ?
Obviously I don't want to leave the backlight on for longer than necessary when it is NOT connected to external power,.
I was hoping that there are either some separate settings that I haven't discovered,
which only apply when connected to external power, or failing that maybe an App that will do the job ???
Thanks,

When you first plug your phone in, it should go to the clock and that does stay lit. Other than that, there is no way to set the phone so that balcklight stays on.

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.

Is there a MagSafe 2 compatible portable external power source for the retina display MacBook Pro?

I’m using a retina display MacBook Pro with the MagSafe 2 connection. I would like to have a portable external power source to extend the use of my laptop on long field trips where I am away from power sources. Swapping batteries is not an option for this generation of MacBook Pros. There seem to be many options for PC’s and even iPhones/iPads/iPods but the MagSafe 2 connection seems to be the issue. I saw one link that suggested buying an Apple MagSafe 2 power adapter and performing surgery on the power cord (using components provided by the vendor) so that the adapter would run on their back up battery. I was hoping for a more esthetically pleasing solution. Any suggestions? Does this product exist and I just missed it? Clearly, if a MagSafe(1) compatible external battery existed I could adapt that using the MagSafe to MagSafe 2 converter.

Sparon,
I wouldn’t recommend using an underpowered AC adapter with your MacBook Pro. It sounds as though the best solution would be to get a different laptop bag with a sufficiently large side pocket.

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..

Can i add an external power button to my mac?

I've got a Mac Pro early 2008 2.8ghz 8 core, I'm going to be putting my mac in another room, how can I add an external power on button?
Are there USB options? Or are there inputs inside the mac that I can connect too?
Many Thanks
Matt

Yes I was going to Hide it under the stairs, and then have the basics on my desk in the attempt to cut down amount of cables.
I realise I can use sleep mode, but I want to avoid it being in standby to save on the electricity bill.
At the moment I don't have it all set up, but I think I may have just remember, but I have the 30" cinema display, I know its got a Power Button, can this be reprogrammed to Power the machine on and Off? I remember the option for sleep.
If anyone has it to check i'll be grateful.
Many thanks
Matt

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.
