Fn-F7 toggles the set of display devices active (CRT, LCD, Both), so cycling through that will restore the screen from the state of backlit but no image, at least for me.
Strange, on my notebooks (Gericom and Compaq) is Fn-F5!!! However IBMis always different ;-). Try also CTRL-ALT-BACKSPACE which kill your X session (all data in X lost) but maybe it helps because it restart X server what mean reinit of
