laptop problems

[russie]

I bought a laptop but my browser and my laptop screen keeps on blacking out and the people who sold me on Lenovo Concept Store Festival Mall & PC Express didn't fix the problem. Is it the laptop or an OS problem? Coz Im not getting a good resolution from their CS people

My laptop has been reformatted by the store I bought it but I still experience the blackout browser and screen. They don’t seem to want to replace it with a new laptop. Idk whats the problem and how to fix it i thought it can be fix with reformat so what to do now if thats the case is it as good as trash?
