I sent my computer out for repair under warranty for an LCD display replacement and it came back with a random white screen on boot. It is random and is not connected to anything previously attempted. 85% of the time it is OK, then out of no where when I boot it up white screen. Thanks for any advice, it will be going back but I do not want it comming back unresolved. Hoping for some info for argument sake in case they tell me it fine...again thanks! Jerry
