Hi, I have one problem with my Asus W680 board and I was wondering if anyone has solved this as well...
Basic configuration, fresh installation, IPMI not connected, i5 14500, 32GB, 1GB SSD.
Consumption in idle mode is around 25W.
I have a network cable plugged in - this is an important note! 🙂
If I enable all ASPM states in the BIOS and run powertop --auto-tune, it has no effect on consumption.
Then I disconnect the network cable, monitor and keyboard and power consumption drops to 14W (and I haven't exhausted all the options for optimizing that).
If I then connect back the network cable, the consumption jumps to 25W.
If I then connect the keyboard and mouse, the consumption is the same 25W.
If I disconnect the network cable so consumption drops to 17W.
If I disconnect the keyboard and mouse I'm back to 14W.
The board has 2x 2.5Gb and it doesn't matter if one UTP is connected or both. Consumption is still 25W.
The network cards on the board are of the i226-LM type.
EEE is disabled by default. If I try to turn it on, it works fine on one port, when I try on the other port it always freezes.
Does anyone have a similar experience? Do you have any advice or solution?
Is it normal for connecting a network cable to make a 10W difference in consumption? (without monitor and keyboard).
