subnotebook computer

A laptop computer that weighs less than four pounds. In order to reduce weight, subnotebooks often eliminate built-in CD/DVD drives, relying on external units to be plugged in when needed. However, if optical discs are required on the road, an external drive in the same travel bag as the computer generally results in more overall weight than a built-in drive would have added in the first place. For features of a portable computer, see laptop computer. See notebook computer.

Sony VAIO 505G

At three pounds and less than an inch thick, the 505G set a trend in 1998 for subnotebooks. The floppy and CD-ROM drives were external to reduce weight, and a docking station was included. (Image courtesy of Sony Corporation.)
