- 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.
