bricked my Samsung NP300E5C today.
Tried to install latest Ubuntu 64bit on a brand new samsung ssd;
used Ubuntu32bit before.
switched on sata3 mode in bios before installation - no other changes
got critical errors during installation
then i wanted to switch back sata mode; got something like "bios ... full ???" error message when trying to save the settings
now black screen - no reaction at all
removed nvram battery - no reaction
