Received Laptop with defect hardware. Mouse pointer moved continues to left bottom corner to open Start menu. Strange round circles at the left of screen. Talked with MSI support. They told me to send back for repair. Need to wait at least 20 days for repair, and I have to pay for all the shipping cost. I was very disappointed about MSI's customer care!.Amazon approved return for credit!.I'm not buy any MSI computer in the future.
