How can I turn off HDD power management at boot and resume?
From what I understand, putting 'hdparm -B 255 /dev/sda' in /etc/rc.local is not the way to do it (and probably won't work for resume from suspend). What is the recommended way to do this?
You could try https://aur.archlinux.org/packages/systemd-hddapm

Can't turn off WiFi Power Management with iwconfig
I had an issue with my WiFi connection dropping occasionally, and I found that my situation was the same as described in this part of the Wicd wiki article: <https://wiki.archlinux.org/index.php/Wi … connecting>, so I used iwconfig to turn power management off, like it said. But, the disconnecting issue is still there. I think power management is still on, because of this:
[<...>]$ cat "/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net/wlan0/power/control"
auto
[<...>]$ cat "/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net/wlan0/device/power/control"
on
Yet, iwconfig still shows that power management is off:
[<...>]$ iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"<...>"
Mode:Managed Frequency:2.437 GHz Access Point: 00:21:A0:F9:FD:C3

How can I turn off the 101ncmdt on my camera and just have a camera
my phone camera use to work very well and some how it got some other thing when I go to camera and it is called 101NCMDT. Now all my photos go to this mode instead of just camera. Because of this I can not send pictures to a lot of people. I hate it and just want my old simple camera on my phone back. It has also made the camera take pictures slower and it is very frustrating. who am I writing to anyway?
Let's get your camera working again, 1knarlysurfrat. That's definitely a strange mode. What phone do you have? Did you download any new applications before this started?

Satellite A660 How can i turn off the lighting of the power button?
Hello, I recently bought a new Toshiba A660-1FL.
However bothers me is the lighting of the multimedia keys, if I work in the dark.
In Bios I could turn off the led illumination, but the power on/off button is still lighting,that distracts me when i am working.
This notebook has two power LED, so the power on lighting is in my opinion, unnecessary.
My question is: How can i turn off the lighting of the power button?Here you can see the LED with the same function in front of you: http://s3.imgimg.de/uploads/t009aae62jpg.jpg
Yes in fact, the difference is color, design, but also location and brightness of the LED.
For me, this LED is too bright and it is distracting in the dark, as you can see here: http://s3.imgimg.de/uploads/leddf570760jpg.jpg
I was today at a local electronics store, and saw that Toshiba has the brightest Power LED on A660, but why it must be placed under the LCD and not in the front as in my old notebook Toshiba A210.
I also had the idea with a tape, but it would look ugly, and it must be removable without residue.
P.S. Also the fingerprints on the glossy keyboard do not look nice. -

How can I turn off this "feature" and have the power button bring me the shut down / restart / sleep dialog by default again?
With the position of the power button on the Retina MacBooks, any mistake turns off the screen in the middle of a presentation or any activity using a projector or big screen — a huge waste of time to wake up the display, enter password, have the projector sync back, watch audience disconnecting from what was being discussed, etc.
This is very annoying, and seems to add to the increasing collection of options Apple decided to make by itself instead of allowing the user to choose.
Come on Apple guys, I'm using my Mac because I want options and lots of preferences to tweak to my needs.
If I needed the lobotomized version I'd be using my iPad!
Any way (official or hack) to change this button back to its proper funcionality?
Thanks!cterra wrote:

Not what you want, but you can get the shut down / restart / sleep dialog by holding the power button -
How can I turn off base64 email encoding in iPlanet Process Manager?
Email sent out from a workflow running in the Process
Manager seems to be base64 encoded. How can I turn
off the encoding?No worries. Typically you can rename a machine by just changing the name System Preferences -> Sharing. But there is also a command line option to adjust the name, and if you don't use the command line option, the server freaks out and will alert you about the change forever. ie - for servers, you need to use the command I describe below.
The command is called changeip and can be run from command line in Terminal.app. It is for manually chaning the ip address and or name of a machine. It basically has 4 parameters: old ip address, new ip address, old machine name, new machine name.
Basically the command looks like this:
sudo changeip OLDIPADDRESS NEWIPADDRESS OLDNAME NEWNAME
If any value is being kept the same, just repeat the identical information as both the old and new value.
Example 1: Changing the IP address and host name. This would update the machine's ip address to be 192.168.1.2 and its name would be update to my_new_name.
sudo changeip 192.168.1.1 192.168.1.2 my_old_name my_new_name
Example 2: Keeping the IP address the same but updating the name. This would update the machine's name to my_new_name but would keep the same ip address.
sudo changeip 192.168.1.1 192.168.1.1 my_old_name my_new_name
Most likely you're just wanting to update the name, in which case you should follow the second example. If you run this, be sure to reboot the machine afterwards and test to make sure that any enabled services are running properly. -

How can I turn off my Apple TV?
There is no power switch. You cannot turn off your Apple TV. You can only put it in standby (sleep) mode. To power the unit off your only option is to pull the plug.

How can I turn off other languages on my ipad the next generation running ios7? I have the international language set to English but it's showing a foreign language and sometimes it shows the foreign language with English. Thank you.
The complete backup and restore procedure is explained in the link above.
If you don't want to do a restore, then your iPad may remain in the unstable state you have for the moment.
You can change the country in the App Store. Have a look at the bottom of the App Store screen, you can change the country and also do the permanent change via Manage > Account.
You can change the language in iTunes via General Preferences > under General tab. -
How can I turn off the wireless modem on my HPG5200uk Desktop?
How can I turn off the wireless modem on my HPG5200uk Desktop? I have an ethernet connection, and don't want to be blasted by unnecessary radio waves.
This question was solved.
View Solution.Hi,
You may not have a wireless network adapter.
If it is not in Network Adapters and you have no Device Manager errors or disabled devices under Network Adapters then that would be the case.
