Laptop Scanner Mystery

Laptop Scanner Mystery


I bought a refurbished Dell 7420e laptop to replace my aging Dell 7470. The 7470 has an S key that works irregularly.

In the past, I have used xsane to run an HP DeskJet 2600 All-in-One Printer flatbed scanner.

Dell laptops have a “backlight”, and the letters on the black-body of the keys can glow under the right circumstances. Very handy when positioning your fingers on the keyboard when in dim rooms. After installing Arch Linux, the 7420e keyboard would not illuminate. The keyboard backlight worked, the POST flashed it during reboots.

After installing Arch Linux, the 7420e would not suspend when I closed the lid, it just stayed on, display lit up brightly.
