Easynote MX37 just died?

on starting laptop after install of windows 7 laptop started bios update, I let it continue until it said bios flash sucessful. it stayed like that for a while and would not respond to anything so I removed the battery to reboot, now everything is dead and even the power supply light does not come on , any idea what happend and hopefully a solution.
Thanks
Andy
