When batteries run out in a Gameboy then you turn it back on, it can run for a short while. Why?

While the device is on it is consuming power. Placing an electrical load on the battery causes the voltage to "sag" a little. Once the voltage sags below a certain point, the device detects it as a dead battery. Turning off the device relieves the batteries of the load and the chemical reaction inside the cells quickly recovers the voltage to a point above what the device considers "dead." As soon as you turn the device on again it consumes what little power was generated in the down time and reverts to "dead" status.
