I am assuming that too. Hibernate is suspend-to-disk and the machine is then turned off. Standby/Suspend would be suspend-to-ram and would need continuous power to keep the ram alive. > What do you mean by 'enough to run the power button'? When suspended to > disk, isn't the system completely off? Most of the system is off. But the power button is electronic. It takes just a tiny little bit of power to sense the button and then activate the power supply. It is almost a zero power state. Power isn't needed for the computer since nothing is running but power is needed for the switch. In the old days the power switch was a simple physical power switch. The switch went "clunk" and power was either connected or disconnected. The machine couldn't turn itself off but could only say it was now safe to remove the power. But these days almost all computers use a smart electronically driven power supply that can turn itself off and on. Or allows the machine to wake up automatically upon a set time. Also machines might be configured for a Wake-On-LAN magic packet in which case the networking would also be active. You may have seen Wake On LAN available in the BIOS settings. (I don't know if the x200 in particular has WOL.) The LAN would of course draw significantly more power, for a laptop. But for a desktop the amount of power to drive the LAN card is small. A lot of larger sites configure machines for wake on LAN so that they can wake them up in the middle of the night for backup and for updates and then shut them down again when that is done. Hmm... Thinking about this more makes me think you should probably make sure that Wake-On-LAN isn't enabled in the BIOS. Since that would need to keep the LAN powered up while off or hibernated. Bob
