Shutting off your display completely, would not be adviseable. Just think
what would happen, if your computer hangs, and you need sighted helpif your
screen reader stops working, and you need sighted assistance. The screen
shut off, will leave your sighted assistant just as helplessly lost as you.
And, since you don't know if your computer has locked itself, it would not
even help to have remembered the key sequence for going to the controlpanel
or the like to turn the screen on again.
Some years ago, one person adviced the following, which I never have had the
chance of testing myself, so it will have to stand on its own. If anyone
have the chance of testing it, and come back with the results, it would be
greatly appreciated. What was suggested, was to get hold of an external
monitor plug. No cable, no monitor, simply just the plugg itself. It might
be obtained from your local dealers scrape yard, or the like; and would be
of very low cost. The person that suggested it to me, claimed that the
laptop would recognize that a plugg had been inserted, thinking this would
mean an external monitor was operative, and simply switch off the internal
laptop screen. Hmm, well, only remember that most laptops have a setting,
that will tell whether the internal screen has to be turned off, when an
external screen is connected; or to leave the computer in a dual-monitor
mode, on which this workaround would have no effect at all.
Another user suggested for you to keep the lid of your laptop closed. I do
find it in its place here, to put out a tiny warning. This due to a couple
of reasons. First, my old laptop actually had its fan intake located right
above the keyboard. This would mean, closing the lid, would block for the
fan intake, hence causing little or no cooling of your computer. And, even
when this fan location is not the case, modern laptops tend to develop quite
an amount of heat. They have been engineered the way, that the big surface
of the keyboard area, that will be exposed when the lid is open, serves as a
cooling area. In other words, the 'close the lid' idea, has to be on your
own risk of overheating your system. Specially so, if you are running any
software or process, that uses excessive resources. If you try it out, and
find your fan to speed up, or your computer to be unusually heated, I'd
suggest for you immediately to find another way of saving battery life. Not
only can overheating your system cause fatal errors on the system itself,
but it also will shorten your battery's lifetime. First your battery might
have a shorter usage-time this very charge, but repeatedly overheating your
system or battery, will cause chemical reactions in your battery cells, that
will shorten it's overall lifetime.
Some laptops have their sensoring switch for the lid accesible. You will
feel it as a tiny PIN-like thing, coming up through the top of your laptop's
keyboard area. Usually its located near the one side. If your computer has
this construction, placing a small piece of tape over this switch, will
cause it to be pressed down. The computer now will think the lid has been
shut, and hence turn off the screen.

Hi all,
Is there a way I can turn off completely the display on my laptop? I would
like to conserve power where ever I can and the display does take up a lot
I
am guessing.
Many thanks.
