Re: screen curtain and saving battery


Where did the sighted person look at the screen?  Was it dark in the room or was there light from other sources?  Others may comment but I would think that if you set the brightness as low as you can, little or very little battery power would be used by the small amount of light shown.

the screen but unfortunately my Dell is not having this keyboard
Gene i think that depends on the brightness level you are allowed to
reach on the laptop. I set the brightness to 0% but according to
sighted help the screen is still viewable. I don't have any experience
about this but i remember someone had posted a way to add a keyboard
shortcut to NVDA to turn off the touch pad and it is working perfectly
well on my device that is also lacking a shortcut to enable this
option I hope that there is a possibility to do that to the display as
and back to my original question: how does screen curtain in NVDA work?
thank you

Whether you can turn off the screen or not, you can dim the screen to a
point where, I would think, little power would be used and the screen
being on would have a negligible effect on running time per charge.

Hi all. In my previous laptops there was the option to turn off the
by pressing a key combination. But, with my new laptop which is from the
Dell brand this option is not available unfortunately. I want to know
the screen curtain feature in NVDA does enabling it saves battery or it
only meant  for privacy purposes? also, does anyone knows of a way to
the screen really turned off, i mean to have an option similar to what
present in many laptops
I am interested in turning off the display to make the battery last
Thank you
