I remember reading that the T400 was supposed to have the feature that would allow the USB ports to be powered even when the machine was in standby, so you could essentially use the battery to charge mobile phones or things like that. Anyone know how to enable this?

It is a setting in the Lenovo Power Manager under "Global Power Settings".

Yeah, found that... I have "enable always on USB" checked, but still no power on any of the ports when I standby the machine. ;-(

Is your Thinkpad plugged in? It only works when your Thinkpad is connected with the AC adapter.

yeah, I tried it both on AC and battery power (this was before I knew battery only wasn't supported) and got nothing ;-( Also checked the BIOS and it's enabled there as well...

there aren't any operating system requirements, right? any reason it shouldn't work on XP/SP3?
