Just got it yesterday. After I powered it on, the screen showed the lenovo logo and then went blank. I tried to restart and reset the computer, it still won't work. Today I had a lengthy and tedious chat with a lenovo tech but still couldn't solve the problem. I'm returning it to get the full refund!BTW, the lenovo tech was also awful. He seemed to be indifferent, slow in response and incompetent. I'll never buy a lenovo again!
