IBM ThinkPad 240 is an ultra-portable laptop computer designed and produced by IBM circa 2000. It is one of the few ThinkPad 200 series models made available in America and smallest and lightest ThinkPad model produced to date.


The first 240 series models included the 300 MHz Mobile Celeron processor, 64MB built-in RAM and one slot for memory expansion. The laptop also was one of the first to feature the Mini PCI card slot. No built-in optical drive or diskette drive was included due to size limitations. External drive access was via a USB 1.0 port and/or the IBM external drive connector. The unit shipped either with a standard 6 GB hard disk drive or with the 12GB upgrade option.

All 240 series models feature a 10.4 TFT display, and the first models featured NeoMagic MagicGraph128XD graphics chips with 2 MB of video memory. The 240 is capable of displaying up to SVGA (800x600) on the TFT display, with XGA output available to an external monitor. All 240s also have audio controllers and VGA ports to connect to external display devices.


  • IBM ThinkPad 240X - Supplied with Windows 2000, and featured the modestly improved SMI LynxEM+ graphics chip with 2MB video memory. Also featured the new Pentium III processor at clock speeds to 500 MHz.
