Sound Laptop stops recording

Recording. Everything OK. Suddenly loud continuing noise from laptop stops track recording. Cut off monitors. Laptop speakers keep the loud noise going. Cut off Cubase. Sound stops.
The longer I work on one track, the sooner it starts. Maddening. I want to record, I’m not much of a pc man. What is going on? Does someone know?
