One approach here would be to have launched task manager before the problem arises.
If task manager is running and J is pre-selected within task manager, selecting task manager (using the mouse or alt-tab) then hitting the delete key (and then confirming on the resulting popup -- probably hitting y or enter) should work. That said, I think you should seriously consider setting the swap file size on this laptop to be as large as the amount of physical ram you have. (Or, double that, if you have enough free space.)
