Delayed monitor power-on

In many computer systems, the mains for the monitor is derived from the computer, so that when the computer is switched on, the monitor is switched on also. This can give rise to such a high current, that the domestic mains fuse may blow. This is not just annoying, but it can give rise to data loss and even damage to the hard disk. This difficulty may be remedied by a slow-blow fuse, a separate mains switch for the monitor or the power-on delay in the circuit diagram shown.
