Vostro 3550 laptop i3 LCD looses sync (like old TV when the loose horizontal sync
I am used to company issued Vostro laptops. My (new to me) Vostro 3550 display looses horizontal sync (as in the old tv's when they loose the horizontal oscillator). I do not get an error code. Hard power off and reboot brings it back to working.
I leave my laptop on 24/7, plugged in to 110V.. It's not heat related because fan is not running. I have upgraded to 480gb SSD (cut down in fan running time, BTW)..
