Power Supply - IBM PS/2 35 SX Hardware Maintenance Reference

3.1 Power Supply

The power supply switches to either the 100--125 V ac or 200--240 V ac
range when the power cord is plugged into an outlet.
converted to the proper dc operating voltages.
When the system is powered-off for five seconds or more and then
powered-on, the power supply generates a 'power good' signal that resets
the system logic. The presence of the 'power good' signal indicates that
the power supply is operating properly.
The 'power good' signal turns on the green power-good light on the front
of the system. If the green light is not on, the power supply is not
functioning properly.
Note: There may be a 3 to 5 second delay before output voltages are
generated after power-on due to system sequencing requirements.
