MMMN, Thanks for your advice. But contrary to your advice, I have gone throguh lots of problems with dell. First one of the letter keys puffed off and then I need to replace the hard drive. I have very unpleasent experience with DELL. So I am now kind of decided not to buy DELL in my life and recommend others not to buy Dell too. This is terrible. Hope I wont lost my data. Cheers
