go flatline

( v.)

   [from   cyberpunk  SF,  refers  to  flattening  of  EEG  traces  upon
   brain-death] (also adjectival flatlined).

   1.  To  {die},  terminate,  or  fail,  esp.  irreversibly.  In hacker
   parlance, this is used of machines only, human death being considered
   somewhat too serious a matter to employ jargon-jokes about.

   2. To go completely quiescent; said of machines undergoing controlled
   shutdown. "You can suffer file damage if you shut down Unix but power
   off before the system has gone flatline."

   3.  Of a video tube, to fail by losing vertical scan, so all one sees
   is a bright horizontal line bisecting the screen.
