Your friend asks for your because her laptop screen is too dim to read anything. what is the first step you should take to fix the problem?

I would do three things:

- connect the laptop to a power supply

- take it into a dark room to maybe see any thing

- press the Fn key combination to increase the brightness.

Most probably the question is suggesting a low battery causes the laptop to dim the display, so the power supply would be the best action.

Mostly the problem would be with the adjustment of the “brightness and contrast” value. I would help my friend to set a value of brightness and contrast value by using the button provided in the edge of the laptop or the short cut keys available in the keyboard. It is very similar to the settings which are done in television.

Even after changing if the monitor display is dim, then there is a hardware issue which needs to be trouble shooted by the system engineer. It might either be screen or monitor needs a change or brightness adjustment button may be faultier.
