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 - I can still see a little bit. The screen also switches back on sometimes.
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)?
I would really appreciate any help.
Many thanks in advance,
