I purchased this ultrabook year 2014 and it worked really well until one day, right after the warranty expired!!!
I brought it to the technician but the only solution they have is to change the motherboard. OK, after less than 2 years its motherboard is already bad. Is that possible? What could be wrong? My old laptop worked for almost 6 years, and this dell ultrabook is just less than 2 years. Too disappointed!!! I spent so much money for nothing.
The mainboard is newer notebooks is basically everything inside the system - CPU, GPU, i/O chips -- even in some cases the memory for the system. They can and do fail for any of a host of reasons. Unfortunately, as more and more parts are now integrated onto mainboards, the chances for failure increase, as does the cost of repair.
