• With no headphone jack, how to use the iPhone in my car 7

  Okay, so here's the challenge.  I have a power source and a headphone and not Bluetooth.  It works perfectly with iPhones before 7.  But with 7, it isn't possible to use the same configuration I had for years.  I own my car, and I have no interest in buying a new car just to support a new phone.  And since this will be a problem for the years to come if I stay with Apple, I would like to know what are the solutions are available.

  So, how to use the new iPhone 7 while remaining responsible and using my car speakers?  Dongles Bluetooth that I need to reload, it's probably not.

  Thus, looking for ideas that might have people.  I can't be the only one with this concern.

  It's almost a certainty that a third party adapter will appear quickly. The new Macbook has a single port usb - c and people asked the same question, 'how to load and use USB at the same time." There are today dozens of solutions for the Macbook, and then it will be with the iPhone 7. An adapter with a 3.5 mm jack and a port of loading Lightening would be my guess. Kickstarter entrepreneurs are probably already working on it.

• How to use the capture and the print button

  I tried to figure out how to use the capture and the "print" button, or add or what you call. I press it and the whole page of a different color changes, so I try to cut the section I want but I don't know how to send it to the printer. Can someone help me with this. I'm not at savvy with tech stuff, but when I find a recipe or something and it doesn't have an option to print a certain area, I can't understand how to use it?

  Thank you

  Andi Starbuck

  That happens to me is, I click and drag to make a rectangle of yellow selection, and as soon as I raise my finger on the mouse button, the part I've selected is captured as an image, a new tab opens and preview before printing, the image display. I can use the installation of the Page or simply print. But if I close the preview, this temporary image vanishes and I'm back on the page where I started. You see something different?

• How to use the Print Screen function?

  I've seen various descriptions of how to use the print screen function.

  It would be nice to actually tell one that works.  None have worked for me.

  [Fn] and Prt SCr does not work.

  CTRL and Prt SCr does not work.

  CTRL, Alt, and Prt SCr does not work.

  [Fn], Ctrl and Prt SCr does not work.

  If anyone knows the correct method to activate the screen capture function which would be a good thing.

  From the looks of things, HP has a big problem with this function.

  Here's a microsoft articleon the use of the screenshot function.

  This should answer your questions.

  Thanks for taking a peek.

• How to use the adapter from the wall with my Mac Pro laptop?

  How to use the adapter from the wall with my Mac Pro laptop?

  The AC wall connector is not compatible with the outlet on the MBP?  As the MBP charger will work from 100v to 240v, a transformer is necessary.  You need a converter that connects to the power outlet home and is compatible with your MBP.  You can buy the Apple travel kit:

  http://www.Apple.com/shop/product/MD837AM/A/Apple-world-travel-adapter-Kit

  Or you can use a single specific converter for the geographical area:

  http://www.Amazon.com/orei-grounded-universal-adapter-Singapore/DP/B004SCSV2U/re f = sr_1_4? ie = UTF8 & qid = 1460735377 & sr = 8-4 & keywords = us + in + uk + power + adapter

  (it is a UK USA example)

  Or you can get the converter that adapts the charger directly:

  http://www.Amazon.com/HIOTECH%C2%AE-extension-charger-connecting-specification/d p/B00MA48JZW/ref = sr_1_3? ie = UTF8 & qid = 1460735486 & sr = 8-3 & keywords = us + in + uk + power + ad aptor + apple + charger + cord

  (again, this is for a UK plug.)

  Ciao.

• How to use the software keyboard Toshiba 50L9450VE TV?

  I just bought a LED TV model 50L9450VE. When installing, I need to enter the password for the wifi network. The remote doesn't have a keyboard of the letter, and the TV shows a soft keyboard to enter the password. How to use the software keyboard? I can't figure out how to get the cursor in it; the manual does not say, and I can't find the information online. Thank you.

  Hershel

  Suppose you are from Israel? Although this model is not made for the EU market, but probably for the Asian market, it looks like the European L93 series.
  You will find how to operate the software keyboard (page 52): http://www.toshiba-om.net/pdf/manual...h-Specific.pdf

• How to use the recovery CD?

  Hello

  Ive lost the instructions to tell me how to use the recovery CD. I forgot, I need to press to access the disks when I reboot!

  Can anyone help please?
  St. Clare

  Hi clear, before using the recovery CD make you that all important data has been saved to the floppy or USB key because the procedure will erase the entire hard drive. The method for booting from a cΘdΘrom may vary according to the model number of your laptop, but it's something like hold the 'B' button for the Toshiba Startup logo. If this fails you can try to change the boot sequence or use the Toshiba from Windows or the BIOS configuration tool (ESC then F1 when prompted from a cold start) make CD-ROM the first device startup in the list.
