A technician has received a laptop that is having problems with the screen. The user is reporting that the display is too dim and difficult to see. Which of the following steps should the technician…

An anti-glare filter reduces reflections and glare but does not increase brightness; it would worsen perceived brightness on an already dim display.

Laptop keyboards include function key combinations (typically Fn + a brightness key) that directly control the display brightness level through the operating system. This is the simplest, fastest, and most non-invasive first step to resolve a dim display, following the troubleshooting principle of checking the easiest and most likely causes before moving to complex hardware repairs or driver changes.

Replacing the LCD backlight is an invasive hardware repair that should only be attempted after confirming software and settings adjustments cannot resolve the issue.

Updating display drivers may resolve color or resolution issues but is not the first step for a simple brightness problem that can be adjusted via function keys.
