Strangely the above laptop has repeatedly turned its screen off several times.The lights are all on, but the screen goes completely dead. On restart the screen is okay, for about 10 minutes then it goes blank again! We've restarted it a few times and its done it again and again. I've booted it up in safe mode and checked the latest AV updates etc, which are up to date. There haven't been any recent software additions.
We're now backing things up just in case!
Easiest way to check this problem is connecting an external monitor. If you notice the same behavior on external monitor it seems to be a problem of software or internal hardware. Otherwise it’s just the internal monitor that is malfunctioning.
Not 100% sure if you have the same setup as the laptop I have, but this happened to me on several occasions and I thought it was a screen burnout or a software problem despite the fact that I'd only had the laptop for 5 days.
I managed to resolve it, but had to connect to an external monitor to do so. When I right clicked on the desktop a menu appears with a tab called graphic options. Click on this then choose output tools / clone displays / built in display + monitor. This should resolve your problemo.
