Source-derived summary

IBM ThinkPad 240 is an ultra-portable laptop computer designed and produced by IBM from June 1999 to 2001. It is one of the few ThinkPad 200 series models made available in America and was the smallest and lightest ThinkPad model produced to date. The 240 series was discontinued, and it (as well as the 570 series) was replaced with the ThinkPad X series in 2000.

Features

The first 240 series models included the 300 MHz Mobile Celeron processor, 64 MB built-in RAM and one slot for memory expansion (maximum 320 MB). 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 floppy drive connector. The unit shipped either with a standard 6 GB hard disk drive or with the 12 GB 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.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “ThinkPad 240”, the useful work is to connect “computer model by IBM” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q5969074. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1999, 2001 and 2000.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
