On the SFP/ER the spoilers are mechanical/hydraulic between down and flight detent. Between flight and up they are electro/hydraulic. When the auto speedbrake circuit breaker is pulled/collared as part of the MEL the solenoid operated valves for the flight spoilers are disabled. So instead of having full travel of 56 deg. for spoilers 2,3,10,11 and 65 deg. for 4,5,8,9 you only have 19.5/24.5 deg.
