IMac connected to TV, can I turn the iMac screen off?

Hi,
I connected my Intel (white 20") iMac to my TV and I'm using the TV screen as the main screen with the menu bar and all that. But the iMac screen is always on, until you launch Front Row or Hulu..etc. then the iMac screen turns off. Is there a way to make the iMac screen to stay off permanently?
Thanks
Gene

On the MacBook, you can wake it while the lid is closed, and the built-in display will not be used. You can then open the lid, and the built-in display should still stay off. At least, that's how it worked with my older PowerBook. So the MacBook design is capable of doing it without any additional software; Remote Buddy just takes a short cut, which is why it is kind of cool, like it does to change the "Main display" from one to the other, or "Toggle mirroring," without opening System Preferences Displays pane Arrangement tab.
I was exactly where you specified in the Remote Buddy menu. The brightness control can adjust the brightness exactly like the built-in control, but even the lowest setting is not an OFF setting.

Can i turn the Laptop screen off while connecting the TV?

Dear All,
I am connecting my Mac to TV 32'' via mini display port converted to HDMI.
I am using it on MAC OS X 10.6.6, and on Windows 7 Ultimate SP1 also.
when i am connecting my TV, the 2 screens are on, Laptop screen and TV screen.
Can i turn the Laptop screen off while connecting the TV?
how to do this on both operating systems?
Thanks & Regards,
Boudy,

The quick answer is, hook up the tv to the computer, close the lid, then wake the computer up by clicking the mouse while the lid is closed. Not sure if it'll work while running windows, but I'd bet it does if you have the mac drivers installed on the win os.

How do I turn the touch screen off?

Is there a way to turn the touch screen off to avoid mistakenly calling someone when the phone is in a pocket or purse?
thx

You can put your iPhone into screen-lock mode (also called sleep mode). It is not off when in this mode: It can still receive calls and other data, but it will not respond to touches on the display, it will not display anything on the screen (except briefly when new data comes in, such as a phone call), and will use much less battery power.
You can place your iPhone into sleep mode by briefly pressing the power button on the top.
You can wake your iPhone from sleep mode by briefly pressing either the power button on the top of the home button just below the screen.
You can set your iPhone to automatically enter sleep mode after a short period of time within the Settings app.

My Hp Printer can print from my Imac But my printer can not see the Imac to scan Photosmart 5514

My HP printer is a(photosmart5514) Imac can print to it, but the all-in one can not see my Imac to scan

This has been a problem with HP for ages. HP's support forum is filled with this complaint, and no resolution appears evident.
You can try assigning both the iMac and the HP Photosmart 5514 static IP addresses. This will ensure they will remain in the same "place" on your network. This may help.
I recommend you abandon the attempt to initiate scanning from the scanner. Initiate the scan from your computer with HP's Image Zone software.

I am using BT Broadband home hub and want to use my time machine - Can I turn the wireless router off in TM?

Hi,
I have BT home hub which is now my main router in the house. I also have Apple TV which works off the router and a network adapter around the house which is perfect for all my needs. However, I also have a time machine but haven't used it for a while now as it's internal router overrides my current network which causes problems.
Being that i'm not very 'technical' I was hoping someone could give me a 'guide for dummies' instruction on how to turn off the wireless signal inside my time capsule without messing up the BT router?
Many thanks in advance
Alex

Thanks guys,
Sorry, just to clarify, I need to connect the ethernet cable to my home hub and my TC first before i can do this?
And once i've done this will my stuff be backed up via the cable or wireless?
I know these are probably very stupid questions but like I said, i'm a div when it comes to this stuff!

Can you turn the Monitor only off?

I sometimes leave my Mac on for a couple of weeks when I tar el for work since I access it from the road.
The monitor does go to sleep mode, but I was wondering if there is a way to have it simply stay off yet leave
the computer still working?

I have tried Ctrl + Shift + Eject and setting energy saver to 1 minute but as soon as I access the computer from the road the monitor turns on again. I would like to have it stay off completely while I am on the road. Is this even possible on my Mac?

You could try removing the iSight Kext file. It's located in System->Library->Extensions/Apple_iSight.kext You might need a restart since the extension has already loaded.
I've never tried it and I certainly wouldn't just trash the file (make a backup) but that's was the NSA suggests to disable the built in cameras on Macs.

If the place of purchase does not have a 'Lemon' policy (three replacements = refund or complete exchange), sadly you are out of luck.
And Apple themselves do not have any power over what policy a reseller uses. You can call Apple Care and have them replace it, but the odds are you would probably get a standard replacement again like has previously happened. I'm pretty sure Apple holds their own sort of 'Lemon' polocy where if it's been replaced three times through them they'll swap it out for a brand new phone. Not 100% sure though, best bet is too call them again.
And it ***** getting a response like that from their support personel, but hey, they can't all be that bad can they? I'm sure if you plead your case they'll try and help out. I've dealt with them in the past and had one or two people that rubbed me the wrong way, but most of them have been a great help and kept me a happy customer, haha.

Is there a way to turn the wireless capabilities off on an AirPort Express? I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections

Is there a way to turn the wireless capabilities off on an AirPort Express? I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections. For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb. These terrible download speed really only affects the iPhones as my MacBook Pro usually gets the good speed no matter where it is. I don't believe there is anything wrong with my phone because if I am in the part of the house that uses just the extreme the download speeds on the iphone goes up to 50-75mb. As a note I have an AirPort Extreme on the top floor of my house (second floor) that's where my modem is located. On the first floor that's where one airport express is located. I also have another airport express in the basement that is accessed by my landlord. Any thoughts on how to fix this would be helpful.

It appears that your networking goals with the AirPort Express is to use it as a wireless Ethernet bridge instead of using it to extend the wireless range of your AirPort Extreme. The latter requires that the Express Wi-Fi radios be enabled.
If you intended to use the Express as a wireless bridge, you just need to reconfigure it to "Join a wireless" network instead of "Extend a wireless network."

In an extended network, the placement of the extending base station is critical as it can only extend the wireless network at the bandwidth at which it receives it.
Please check out the following AirPort User Tip for details on optimal base station placement.

I am unaware of any PCs that support connection via Target Display Mode. I have never tried it myself, so I don't know if it would work. All you can do is try provided you have an iMac that supports TDM and the proper cable adaptors.

I have been having issues with not receiving texts and voicemails daily, for a few months now. If I turn the phone completely off, when I turn it back on the messages will flood in from hours before. I can't be continually turning off my phone in case someone left me a message. How do I resolve this issue?

Wifi: my Cell phone will remember 10 wifi connections. So delete any you don't use often and your home wifi and try to enter home wifi again.
if it still won't connect to home wifi, call your internet provider for help. You may need a newer router or different settings Or upgraded service. Your phone seeks the best connection and will refuse lesser connections.
last resort. Backup the phone. Do a full reset, then restore as new with the backup.
if still not fixed, go back to apple and insist on repair or replacement.
HOWEVER. voicemail is not a wifi issue, it's a carrier function, which is why the SIM card is a suspect.
