All fairly well the same responses...
Boeings have a "Throttle Hold" function that unpowers the A/T actuators at a set point during the takeoff roll.
For the 737NG it is at 84 knots, and the FMA reflects that change.
After that, for the rest of the takeoff, the throttles are totally manual!
If you're a bit slow getting the thrust up to spec, at 84 knots the throttles will stop advancing, manual input is then needed.
Since most V1s are well in excess of 84 knots, removing one's hand from the throttles at V1 is not a problem!
But, if you abort before 84 knots, and 'as you do' retard the throttles to idle and beyond, the autothrottle will still be trying to advance to the selected takeoff power setting. But above 84 knots, will not!
This is why we select disconnect of autothrottles for every abort, then that's one thing you don't have to think about.
Normal ops for us!
