[Ham-Computers] Computer - Power Management Query

[ham-computers@mailman.qth.net]

Does anyone know a web address or can explain modern power management 
methods. eg

Just upgraded to a Pentium IV ASUS S370 motherboard and notice the following 
when the computer is connected to the mains power socket :

1.  LED on Motherboard continuously ON.
2.  IR Mouse light always ON.
3.  LAN connection always shows ON on the LAN Hub.


I presume this is modern accepted "Low Power" Consumption convention because 
no reference in Manual - is the above a MODE and can it be changed in the BIAS - 
it confuses me. 

One should therefore always disconnect computer from the power before making 
any hardware changes.

Dont want to consume too much bandwidth with this slightly off topic subject but if 
anyone can point me in the right direction would appreciate it.



Regards

Eddie
