Писах на подръжката на Fujitsu и получих следния отговор:
I guess you made a fault by calculating the power consumption!
I guess you have measured the input current at stand by condition!
Maybe it was around 0.23A, so you calculated 230V x 0.23A => around 52Watt
But you should not forget to add the cos ℓ!
The correct calculation is P = U x I x cos ℓ!!
cos ℓ is around 0.15 during stand by condition! It means your real power consumption is less than 8 Watt!
Hope I could help you with this explanation!
You can proof the real power consumption by using a power meter that includes the cos ℓ!
please multiply the 52 Watt with ƞ ~ 0,1 in Standby. Then you have roundabout 5 W.
This seems OK.

Човека излезна прав,електромера върти по бавно на тия "52" вата отколкото 8 ватова крушка
