Hi,
I searched the web for quite a while, but did not find any thread that matched my problem exactly, so I am writing this.
I bought Asus G75vw around 5 months ago and after approximately 2 months the machine just powered down, without any warning. I wouldn't have started worrying if that didn't happen again in 3 weeks. And it feels like it is becoming systematic and every interval between shutdowns is smaller. It happens very randomly, just the keyboard back-lighting disappears and a second later machine powers down.
I am a moderately power user, but I am sure it is not an overheating problem, because laptop is not even warm when that happens. I am thinking to check voltage or something.
Any ideas?
