I stepped on my Tp and now when there is some digital lines stuck on screen. If I hold power button the screen will go dark and when I try to turn back on I get more lines showing on the screen. There are no system sounds coming from Tp at all and other than the lines there is no other activity on screen at all. When plugged into pc there is no reaction from pc at all. I have about a week left in my basic labour warranty. Do I call HP for warranty or am I wasting my time because they will say i physically damaged it even though there is no outward sign of physical damage to Tp? If I call them I should probably leave the part out about stepping on it right? From what I remember they take my credit card info. Do I risk being charged for service and then they still refuse to service it?
