Re: Screen Dimming and Battery Saving


Of these, dimming the screen is most effective - you can't really project your screen onto another monitor unless you have a different monitor connected or using older Windows releases, and screen curtain doesn't dim the screen - it makes the screen go black but doesn't change brightness.
A more effective solution is tweaking power plan settings:
* Make the CPU (processor) go a bit slower.
* Enable power saving mode for the wireless card.
* Tell Windows to turn off the display after a shorter amount of time.
Also, don't use a lot of processor-intensive programs in the background.

Subject: [nvda] Screen Dimming and Battery Saving

Dear all,

I am using NVDA 2020.4 Beta 2 on Windows 10, and I am looking to maximize my laptop's battery life, and as a blind person, I would like to save on the power that the display monitor uses. There are three ways (not necessarily mutually exclusive) that I know that help in screen dimming:
* reducing brightness level from from Settings to 0
* enabling NVDA's screen curtain
* pressing Windows+P and selecting Second screen only For each of these, could you please comment on whether or not they help extend battery life and explain why? Are there other ways to save on display power that I have missed?

I would truly appreciate any assistance.
