I had a scare when my laptop would not turn on this morning. Don't know why and this evening it seems to be fine. My problem is all my warranty info and even how to contact HP is on the computer. I was going to make a hardcopy of this page in case it ever happened again but found this page is only active though the computer, no exterior contact given that I could find. My question is; if my computer does not turn on how do I contact HP to get service?
