Bob, You don't by any chance have the screen dimmed all the way down, do you? Just an 'Occum's Razor' thought. Merry Christmas!

The battery is old, still has (or had) a charge. I mention this because I would expect the battery to power up or attempt to power up the puter if the power cord was defective. The book seems to be still working - slight hum to the hd and the book stays warm This condition simply "just" happened.ie:using the book I put it down,turned to make a phone call picked up the book and - - nothing. No symptoms. Thanks for any input, help, or opinions. Bob R -------------- next part -------------- An HTML attachment was scrubbed...
