The
“
standby connector,
”
unlike the traditional mechanical
switch, is an electronic way to turn the computer
’
s power
off. To use this feature, the power supply system must
permit a shutdown power supply (+5VSB), support the
electronic switch feature, and must also be used with
connector JS1 on the mainboard. For example, when
using Windows 95, your computer will automatically shut
down after having saved your work when you exit
Windows. You do not need to use the mechanical
switch to turn the computer off.
