My T42 doesn't even go to sleep fully. The screen blanks, hard disk spins down, and the little moon LED lights up, but the fan never stops spinning, and I can press Caps Lock and see the LED light up. The moon LED remains lit up, and the screen remains blank, even if I try to wake it up by pressing Fn or opening the lid.
I can also reboot my laptop with Alt+SysRq+S, U, B while it is in this half-sleep state.
