Unable to dim brightness in Dell Studio 1749 laptop

Unable to dim brightness in Dell Studio 1749 laptop: everything I have tried does not allow me to dim the over-bright screen using the win 10 customization tools? Most suggestion offer tweaks that might not be reversed?

 

Laptop powers up with dim screen


Post Windows 7 Home Premium to Windows 10 Home upgrade on my Acer Laptop, everything went reasonably OK apart from having to resize the Reserved System Partition.

After a couple of days, the brightness of the screen at start up is really dim making it difficult to see or do anything. I initially thought that Windows had crashed & did CTRL/ALT/DEL to restart.

The only thing that I can to is hold down the Fn key & press Screen Brightness key which seems to work.

But, why should it do this after a couple of days.

Not aware of having made any changes to initiate this.

Would really like it to boot up at full brightness.

Any suggestions gratefully received.

 

Screen dimming even at 100% brightness

Hi recently bought a Lenovo laptop, a Lenovo V14-ARE laptop, and as soon as I turned it on I noticed, when I put it on 100% brightness it is bright and vivid but then it dims. After a while, the screen brightens again then proceeds to dim once again in a
few seconds. When I plug it in to charge, the screen is bright and vivid but as soon as I unplug it, it dims. I already left clicked on the power icon in the task bar, went to power options and selected "choose when to turn off the display", clicked "change
advanced power settings", scrolled down to "display" and opened its list, but the only option I have for the display's list is "turn off display after", in the Youtube videos I've seen they have an "adaptive brightness" setting or something like that and that
fixes their problem but I don't have that option. My power plan is also in high performance and everything is "on battery" but the problem still happens.

Can this problem be fixed?
