ノートパソコン

1989 is a concrete hardware point for ノートパソコン: Toshiba released the DynaBook J-3100SS001, described by the IPSJ Computer Museum as an A4 binder-size notebook personal computer. The machine weighed 2.7 kg and used an 80C86 CPU, according to the museum record. Daijisen explains ノートパソコン as coming from notebook personal computer, while Seisenban Nihon Kokugo Daijiten analyzes ノート plus パソコン, the Japanese shortening of personal computer. The word formed inside Japanese computer retail language, after パーソナルコンピュータ had already shortened to パソコン in the late 1970s. Toshiba's T1100 in 1985 was a laptop PC, but the 1989 DynaBook framed the notebook category; NEC's PC-9801N followed in 1989. As portable PCs became thinner in the late 1980s and 1990s, ノート, ノートPC, ノートブックPC, サブノート, and モバイルノート formed a product vocabulary. The meaning moved from a notebook-shaped personal computer to the everyday laptop category. Modern ノートパソコン means a laptop computer with screen and keyboard in one folding body. English speakers usually say laptop or notebook computer; note PC is not the normal term, and notebook personal computer sounds like a specification label. Japanese contrasts ノートパソコン with デスクトップパソコン, タブレット, and スマホ. A4サイズ and B5サイズ often appear in older product descriptions. Example: ノートパソコンを買った.
