How to Update Sony Drivers by Yourself?

There are a variety of common alerts along with other messages that you could get in the driver upgrading process, several of which I've paraphrased and listed here along with advice on what you can do:

QUESTION: I have one Vaio SVE14A25CXH once i changed to windows 8.1 and later windows 10 We have lost the initial program's Vaio. In the course of all these transitions keyboard backlight settings have transformed. Currently, it only glows when handled. Just how do i return the function of continual lighting. I have to admit that my Vaio recovery disks are dropped. Thank you.

ANSWER: The keyboard backlight is one of the limitations of Windows 10 operating on your own machine as a result of lack of up-to-date drivers : http://esupport.sony.com/CA/p/model-home.pl?mdl=SVF15A190S&template_id=1®ion_id=3&tab=download#/downloadTab

How to Update Drivers with Device Manager?

1. Open Control Panel



Depending on your version of Windows, Control Panel is usually available from the Start Menu or the Apps screen.

What you do next depends on what Windows operating system you're using:

  • In Windows 10 and Windows 8, tap or click on the Hardware and Sound link.
  • In Windows 7, click System and Security.
  • In Windows Vista, choose System and Maintenance.
  • In Windows XP, click Performance and Maintenance.

Note: If you don't see these options, your Control Panel view may be set to Large icons, Small icons, or Classic View, depending on your version of Windows. If so, find and choose Device Manager from the big collection of icons you see and then skip to Step 3 below.

2. Open Device Manager

  • In Windows 10 and Windows 8, check under the Devices and Printers heading.
  • In Windows 7, look under System.
  • In Windows Vista, you'll find Device Manager towards the bottom of the window.
  • Windows XP Only: You have a few extra steps since Device Manager isn't as easily available in your version of Windows.

From the open Control Panel window, click System, choose the Hardware tab, and then click the Device Manager button.



3. With Device Manager now open, you can view a device's status, update the device drivers, or do whatever other hardware management you came here to do.
