The SLT is a family of laptops released by Compaq Computer Corporation.

The SLT was the first laptop ever released by Compaq, then primarily known as a maker of luggable and desktop computers.

[2] The SLT series was the successor to the Portable III and the predecessor to the more well-known LTE.

The SLT/286 had a 12 MHz Harris or Intel 80C286 processor (both brands were used throughout the SLT/286’s production) and a grayscale (up to 8 shades) backlit VGA LCD screen, the first laptop with this feature.

[2] Compaq's main marketing message for the SLT range was its battery life, up to 3-hours minimum.
