Thanks Twoboxer and saint19 for the advice. I acted on it. To update, yesterday I phoned ASUS warranty repair service, explained the problem much as described in my original post, they agreed to send RMA, I got it and fedexed it yesterday afternoon. That's the good news, so far. Discouraging was that ASUS informed that average turn around time after they recieve the unit is 16 working days. Means, with shipping, I am looking at 4 weeks without the computer. Thanks again.
