Zepto Computers A/S was a Danish computer company founded in 2002. They specialized in customizable laptops and TVs, rebadging and branding notebook computer barebones of OEMs/ODMs like Compal for sale. Zepto operated in Denmark, Sweden and Norway, and throughout the rest of Europe and in Australia via their partners. In Europe, they were one of the few companies where Microsoft Windows was optional and a "naked" computer could consequently be bought at a reduced price, a practice popular among users of Linux and other alternative operating systems.

Zepto's main business was selling highly customisable laptops. The customer would select a series of laptop, and then select which specific parts, like CPU, RAM and HDD they wanted to have and Zepto would integrate it for them. Their machines were designed with this in mind; for example, the single chassis common to all models in the A15 series could accommodate a large range of combinations of CPU, graphics card, RAM, wireless, TV tuner, bluetooth, webcam and fingerprint reader, including one full-size and one half-size PCI Express Mini Card slots for this purpose. They rebadged most of their laptops, sourced from external manufacturers, at their headquarters in Hedehusene, Denmark. Header information in the ACPI DSDT file from the A15 series' BIOS indicates these machines are manufactured by Vestel.
