Sony :: Brand New TT- OS Not Found

I've just received my VGN TTWN/B two days ago. It has Vista Business installed by default and I've been going through the guide page by page to ensure everything's just right as I set it up. It's just fab!

Tonight I opened the power icon on the tooltray when the machine was connected to the mains (window showed: connected. Not charging. 80% charged) and proceeded to the lid/button power functions. Here, I found four boxes, two for AC functionality and two for battery. All four boxes were set to 'sleep'. To experiment, I changed one - the AC lid function to 'hibernate'.

I then closed the lid and returned a while later. By now the screen was black, but the power indicator (on/off button) was still lit green. I attempted to restart using the return key. Nothing happened and several minutes later, I decided to hold in the power on/off button for 5 seconds to try to shut the machine down and restart.

It didn't shut down, and once more I repeated trying to unhibernate using the return key, except this time, up came the phrase: 'Operating system not found.' I used various keys and the same message came up again and again.

Now the machine has been sitting there, black screen and with this message. It's disconnected from the AC and the on/off is still lit green.

I have been tempted to remove the battery and replace it, and start again, but this is where I run out of talent. I don't want to do anything to the TT which will screw it up.

System restore discs were made at the very outset.
