I have searched as thoroughly as I can so as not to waste anybody's time but I can't find any help.
I have a Toshiba satellite 300 with Vista Home Basic and running Ubuntu - dual boot.
Everything was running well.
This morning I updated the 12.10 and then saw calibre running and downloaded the latest version. In a terminal window loaded the commands as suggested by calibre for Linux and then opened the filw manager and double clicked on the claibre shell file to run it. Seemed OK.
Then clicked on calibre on the left hand bar and everything went black and dead.
I tried to start by pushing the start button - no light, no sound, nothing.
I removed the RAM and reinserted it, after removing power and battery for a while - nothing. It might as well be a paperweight.
