I opened my computer at my desk yesterday afternoon to a glitching screen and a little part of the screen blacked out. I would assume these are signs of it being dropped or sat on (something wrong with the lcd screen?) but it never left my desk. I didn't damage it in any way, I had been using it just fine a couple hours before hand. I just got this computer a month ago and have only used it a handful of times. It is only under limited warranty. I just payed 1300 dollars for this computer -it's pretty much the most expensive thing I own and I've been saving up forever for it- and I need it for college in 2 weeks. Does anyone know what could have caused this, and if it could be under the limited warranty?
