In 2006 I bought a low end basic HP notebook ($1000) Played World of Warcraft heavily on that until it broke down in February 2008. The screen wouldn't turn on, I couldn't even see the Windows is starting screen etc etc. I was able to press the power and hear the notebook turning on, but the screen was completely black. Then in March 2008 I bought a Dell xps 1530 laptop ($1500). It was a big upgrade for me and definitely a step up over my Hp notebook. I played WoW for 2 years before quitting in late 2009. Since then I've been using the computer to stream movies online, download stuff, browse online, and do basic lightroom and video editing for upload to youtube. Now this morning my dell won't turn on anymore, the same exact symptoms as my HP notebook I press the power button, hear the fan and harddrive noise, but the screen is completely black. HP lasted me a good 18 months. Dell lasted me a good 4 years and 10 months. I could have use Dell for 2 more years if it didnt break down on me. What could have caused that? does anyone know? Now the reason why I'm posting this is because I bought a Macbook air 2012 (i5/8/256) 2 months ago and it cost me ($1706) exactly. I'm hoping this computer doesnt experience what happned to the above 2 computer I've owned in the past. My goal for this computer is for it to last 6 years maximum, hoping to keep it for that amount of time, and its my only computer that I will be using in that span. has anyone experienced this problem with macbook computers?
