Title:
  [Toshiba Satellite P50-B-10V] CPU Fan stops working

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Usually CPU fan works as expected but in some situations stops working
  causing high temperatures and drastically reduces system performance.

  I haven't found a pattern on this but I think it happens  on the
  following sequence:

  1 - Suspend the computer while connected to power cord
  2 - Disconnect from power and resume system running on battery
  3  - Suspend the system (still on battery)
  4 - Connect power cord, resume system and fan will not work

  As I said I haven't found a pattern, but i THINK this is sequence of
  events that leads to fan failure.
