Hello ,
i've installed windows 7 on a inspirion 1720 and everything worked well until saturday.
they're where 177 upgrades to do so i let my laptop running all night long .
But yesterday morning i saw that the laptop was blocked so i did a restart and now my screen is black ( no backlight ) . when i connect a external screen everything is ok .
does this means that i ave to reinstall windows or is the screen broken ?
