Hello guys,

Why is my brightness slider is adjusted, but has no proper effect on actual brightness? No matter how you adjust the slide, brightness is always at max, only decreases (dims) between 40 and 55.

Checked it in three different OS; Windows 7, 10 and Ubuntu. Shows the same symptoms in each.

Might it be the firmware , graphics driver or the hardware issue?

Computer : Toshiba Satellite L755-S5242.

Welcome to the Forum.
Is the slider a hardware or software tool?

It is a Windows 7 brightness slider, under power options.

Have you checked on a dark room?
Sometimes it is so saturated that you don't see it changing, although it is.
