That would be a hell of a virus though. &nbsp;LOL

I am pretty sure that you can use software (a virus) to switch off the backlight. That's why I made this assumption ... Thanks for your comment anyway.<br />

Dear all,<br />
<br />
I have a Sony Vaio (PCG-FX401) laptop. Recently, the screen has been switching itself off occasionally, and I have had to use an external monitor. The screen is not totally dark - &nbsp;I can still see a little bit. The screen also switches back on sometimes. <br />
<br />
I presume there is something wrong with the backlight (or the mechanism [software?] that switches it off). Please note that I have also changed all the screen (saver) settings to ‘never switch the screen off’. Could I have caught a virus, as it looks like a software problem rather than a hardware problem (the screen works fine sometimes)?<br />
<br />
I would really appreciate any help.<br />
<br />
Many thanks in advance,<br />
<br />

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
