I purchased the chromebook for my daughter to use.  During her online class, the screen went blank.  We tried to reboot the computer and did everything we could, the screen started to leave multi zig zag lines.  After we turned the computer off and reboot it, the zig zag lines stayed on the screen.  We immediately asked for a return.  The seller accepted the return but only gave us almost half of the refund.  We are livid because the chromebook failed with less than two weeks of use (10 days) at approximately less than 3hrs usage per day.  I would NOT trust to buy from this seller again.  We will continue to fight for our complete refund and will update if they comply or not.
