I have an Alienware m18 R1, it was new (about 6 months old) it was running a simulation in multithread mode, so I was using all logic cores. It was running for several days, and at some point, it just went off and is not responding at all. I connect it, and the charger LED is on, but nothing at all happens. I was wondering if this is common, since I had the idea that this was a very powerful computer
