Alienware Gaming Laptop 15 6 Inch Review

A few times when playing a game, the computer would end the session. Just abruptly leave. No idea what occurred or whether a larger problem might be brewing. The second problem is that as of right now, my keyboard is dark and does not respond to typing. When I restarted, nothing happened. After 15 minutes, I closed my lid, and when I opened it again, the keyboard was functioning normally. Is this anything that might come up later?
