Hello, I have a Lenovo Edge 2-15 with windows10, whenever I turn it on it works perfectly fine, but it happens that after closing it to lets say take it to university whenever I open it screen stays black, so what I do is turn in off with the power button then back on, so if there is any app or doc open of couse I lose it but the laptop keeps on working just fine, please help I really have no idea whats the matter but its quite frustrating. Thanks
