Sr. Citizen Level Questions Re Sleep Mode, Brightness, etc. Please

Hi,

Great Forums and folks.
Thanks for all the previous help.

a. For the first time, I tried using the sleep mode.
Worked fine, apparently.

But after a few days with it, it started asking me for a Password when I
woke it up by using the keyboard or mouse.

Why the change ? A real "pain"

b. I tried, really, but cannot see any "simple" slider in System preferences
to simply adjust the monitor brightness.
How do I do it, please ?

c. Might anyone suggest a very simple, uncomplicated screen Saver that can
use a file of photos I have created ?

General question if you have any thoughts on: do you feel that sleep mode, with the additional start stops for the HD, diminishes the HD life as compared to simply leaving it always on ? And the burn-in possibility for the monitor ?

Much thanks,
stay well,
Bob

For monitor brightness, I'd suggest 2 things to look at:

1; within the monitor controls itself, unrelated to Windows. Look at your manual.

or

2: "Night Light", within Windows; you can set it to dim the screen at certain hours; it does use a slider. Type "night light" in your search box or within "settings".

There's probably something else within Windows, but I haven't looked for it.

Screen Saver? Are you referring to Wallpaper? Right click the screen and look at "personalize". And then "background". Choose slideshow.

You can select a folder there and choose how often you want the picture to change.
