In the wake of the recent 'fire hazard' battery recalls, it is now warning: do not use your laptop computer on your lap.

The CPSC states that it is aware of at least 47 incidents involving smoke or fire related to laptop computers, between January 2001 and August 2006. It also reminds users of a number of tips.

As well as 'Computer batteries can get hot during normal use. Do not use your computer on your lap', these include: 'Do not permit a loose battery to come in contact with metal objects, such as coins, keys or jewellery'; 'Do not crush, puncture or put a high degree of pressure on the battery as this can cause an internal short-circuit, resulting in overheating'; and the essential, 'Avoid dropping or bumping the computer. Dropping it, especially on a hard surface, can potentially cause damage to the computer and battery. If you suspect damage contact the manufacturer'.

Of course the most important advice is simple: 'Follow battery usage, storage and charging guidelines found in the user's guide'. RTFM, in other terms (and maybe 'F' stands for 'flaming').
