There's been a few issues with my laptop recently.
1) At times the sound just stops to work. I would have to restart the computer just to get it back on again.
2) Laptop would sometimes shut down on its own.
3) There is a wet smug in the center of my screen (humidity?)
I can't remember if microsoft gave me a warranty on this laptop. If so, how can i retrieve the information needed to bring this laptop in and make it fully funtional again?
Thanks!
