Power Consumption of my PCs measured by Kill A Watt P4400

1. Custom build: AMD Athlon 64 X2 5050e, ECS GF8100VM-M3 motherboard with Gigabit NIC, one hard drive, 80-PLUS CORSAIR CMPSU-400CX 400W PS
   
   
   
   • Hibernating: 2W
   
   
   • Starting up/Shutting down: 50W
   
   
   • Idle: 40W (50W before installing the AMD CPU driver)


2. PowerEdge 400SC: P4 2.4C, 1GB DDR memory, Radeon 9600, one SATA hard drive
   
   
   
   • Hibernating: 1W
   
   
   • Starting up/Shutting down: 108W
   
   
   • Idle: 61W
   
   
   • Web surfing: 70-90W
   
   
   • Playing back a WMV: 78W(81W with high quality mode)
   
   
   • Standby (S3): 4W (7% of idle power)
   
   
   • Standby (S1): 52W (85% of idle power)
   
   
   It costs me about $36=52*24*365/1000*$0.08 for standbying S1 a year. How to avoid that.
