  • situation
    • notebook keeps dead.
  • Possible reason

    • free -mh check memory
    • memory was almost full
  • What I did
    • du -sh /etc check directories memory
      • while checking memories with du -sh /etc/*, I found a huge memory in the place where I didn't expected, log folder.
    • Remove all the useless data
    • Linux Trash path: cd /home/user/.local/share/Trash/
    • rm -rf delete
