I think you don't understand me as well...I don't think you understand.
I know its a hardware issue, and an HP Laptop on top of it.
It needs to be reflowed.
Do you know what a reflow is without a google search?
Taking it back and getting them to replace it with a brand new one is an easier way and SAFER way of doing a reflow. Not anyone should be doing reflow.
Plus it'll be brand new.
