Question

Is there a laptop where you can turn off the backlight of the screen completely?

I have a Pixel Qi tablet where you can turn off the backlight and I use that function all the time. Really saves the eyes if you read or write a lot.

Now, I would like to have that functionality in a laptop too, preferably with a 13.3 inch laptop screen or so.

I don't know how well the Pixel Qi company is doing, haven't seen a lot of updates from they're lately. Maybe there's another company which manufactures a similar screen that you can tip me about?

Again, I'm looking for a laptop where you can turn off the backlight of the screen entirely. Perhaps a Mirasol screen, or did that product turn into vaporware too?

The technology behind is somewhat irrelevant - what's important is that I want to be able to turn off the backlight.

Any tips?

Although shopping requests/recommendations are off-topic for SU, and I think finding a notebook with this specific functionality would be impossible (never seen or heard of one personally), here's a generic hack that could work with many notebooks:

• Open your notebook's LCD shell.
• Find the two power lines that run to the LCD backlight's power inverter (assuming not LED backlit).
• Put a small toggle switch inline with one of the wires.
• Mount the toggle switch through the chassis/shell someplace.
• Profit. :)
