I *think* 'thinkVantage' blue btn should work too. On my T23 I have suspend/wake on lid switch off (in BIOS), preferring to have to use the Fn key to wake. No other keys do that on mine including the ThinkPad key, so then called. While consulting 'sysctl hw.acpi' about that I see: hw.acpi.lid_switch_state: NONE which I assume reflects my don't-do-that BIOS setting. And confirming: # sysctl hw.acpi.lid_switch_state=1 # (or =0) hw.acpi.lid_switch_state: NONE sysctl: hw.acpi.lid_switch_state: Invalid argument which makes sense and was expected .. except that since doing that, closing the lid while awake still just blanks screen, but opening lid now wakes the laptop from sleep! No big deal, just slightly odd .. Cheers, Ian
