I bought the computer and stored it in the box in my closet until it was time to replace my old one. When I tried to turn it on, it wouldn't turn on with the power button...it would turn on with the tech button on the back but when it was released it would immediately turn off again....took it to my computer technician and after a 100 dollar checkup he told me it has a bad motherboard....I live in Ecuador so returning it isn't possible...first and last time buying a refurbished item. It's good for parts only.
