Specifications
Recall
The Wall Street Journal reported that IBM had received 15 complaints of a short circuit occurring between the circuitry and a conductive coating inside the case which, in some instances, has melted a small hole in the case. The short occurs when the laptop is run on batteries, and IBM reported it will install a fuse to stop overheating. They had to issue a recall for 150,000 machines.[2]
Other models
One year after the announcement of the L40SX, on 24 March 1992, four other notebooks were announced by IBM: N51SX, N51SCL, N45SL and the CL57SX.[4] The CL57SX was the first laptop from IBM that featured a color TFT display.[5]
