!Help file for ! application

This application is to change from an external to the internal screen on an
A4 portable in the event of a sudden power cut. Not for use on computers not
fitted with an LCD display
Why?
In theory the A4 portable running form the mains contains its own
uninteruptable power supply. However this is of little use in a power cut if
you are using an external screen as you cannot switch easily between the two.
Try this brief experiment:
Make sure your battery is not completely flat, then with your computer
connected to an external monitor, walk over to the wall socket & switch of
the power to your computer system (make sure you don't switch of anyone
else's or you may be unpopular). Your unsaved work is perfectly safe until
your battery power runs out, but apart from pressing f3-enter to save from
the file with input focus you cannot save any of your work until the power is
restored, which may be several hours longer than the life of your battery.
Now switch the power back on and breathe a sigh of relief.
So that you don't get caught out in a real power cut, Install this
application in the ROOT directory of your hard disc and make sure that it is
the configured drive with the command '*Configure drive 4'.
In a power cut you will have to run the application without the aid of the
mouse so memorise this key sequence:
1) Press f12 (fn-f2)
2) Press ! (shift 1)
3) Press enter three times.
Practice this until you can do it with your eyes closed (you may not be able
to see the keys in a power cut). you can now save your work or continue
working from the internal screen. I hope you never have to use this.
