My mom-in-law and I each have a 2.5 year old Toshiba Satellite. Last night both dropped into a coma. Hold down the start button on each and the various power lights flutter for a mo', there's a little fan noise, then nothing.
What the frig??
My main computers are fine and they have been networked to mine, whereas Mom's has had no direct contact with my laptop. Lots of security on both, almost no software in common.
