TODAY'S DATE to get your warranty to cover it when it's busted good...
There is nothing I can tell you except there are 2 parts they replace. Motherboard and keyboard. One's fairly cheap, the other is not.
Given that a motherboard plus labor can exceed the price of a new laptop, you must deal with them. Your answer should be... It's broken, unusable and I want you to honor your warranty.
Even if you ship it out and back for this issue, it serves as the date you reported the problem and therefore when it fails, you have your laptop in warranty when it's out of warranty...
