Founded in 1939 by Bill Hewlett and Dave Packard in a garage in Palo Alto, California, Hewlett-Packard became a pioneer in electronics and later a major player in the PC market. If you're searching for "history of HP laptops," "first HP laptops," or "HP laptop series," this article provides a detailed overview of the brand's evolution from early calculators and minicomputers in the 1960s–1970s to modern models in the 2020s under HP Inc. We will explore key development stages, the advantages of HP laptops and desktops, the unique "personality" of the brand as an engineering giant, and a thorough breakdown of each major series – from Pavilion and Envy to EliteBook, ZBook, Spectre, Omen, and others. This information will help you understand why HP remains one of the market leaders in 2026, when consumers seek AI integration, sustainability, battery life, and professional performance.

HP is not just a hardware manufacturer – it is a company that invented the first scientific calculator, the first business personal computer, and set quality standards in the industry. With a market share of around 20–25% in the 2020s (according to IDC), HP continues to lead thanks to innovations in displays, battery life, security, and sustainability (HP Planet Partners recycling program). Advantages of HP include high reliability (average lifespan 5–8 years), powerful performance, premium design, and eco-friendly initiatives (recycled plastic in 70% of models). The brand's "personality" is American-Californian engineering precision: a focus on quality, longevity, and user comfort, balancing innovation and practicality. Now, let's break down the evolution step by step and dive deeply into each series.

Beginnings: From Calculators to the First HP Computers (1939–1980s)

HP's history starts not with laptops but with electronics. In 1939, Bill Hewlett and Dave Packard founded the company in a garage, releasing their first product – the HP 200A audio oscillator. In 1968, HP introduced the HP 9100A – the first scientific desktop calculator, considered a prototype of modern computers. In 1972, the HP-35 became the world's first pocket scientific calculator, marking a revolution.

HP's first computers were minicomputers: the HP 2116A (1966) – for scientific calculations.
