to turn off power to the RCX

The sequence of actions necessary in order to turn off a computer or telephone system. Not following the correct power down procedures can cause a loss of data.

To turn off the power switches on the workstation chassis and the monitor.

Any occurrence in a shmup which causes the player's weaponry to lose some or all of the enhancements that it's gained. In shmups without the Retain feature, for instance, players “power down” after being shot down; in other cases touching an enemy craft (as opposed to a shot) will power down the player's craft rather than destroying it; in still other cases, the player's weapon will power down automatically if extra power-ups aren't collected to maintain it. Other variations aside from these exist in different shmups. In some games in which the rank is affected by how powered-up one's craft is, players will sometimes “power down” on purpose to keep the rank from rising too fast.
