Though the Canon PowerShot camera is considered to be one of the best digital cameras on the market, the manufacturer has issued a warning that a number of its PowerShot A530 or A540 cameras have a tendency to overheat.
A press release issued by Canon says:
We have discovered that, in a very small number of PowerShot A530 and PowerShot A540 digitalcameras, the area around the battery cover on the bottom of the camera may become hot. We would like to convey the details of this phenomenon and our service policy.
We have discovered that in cameras where the opening/closing spring on the inside of the battery cover (see images below) sticks out beyond its regular position, if a battery is put into these cameras and the battery cover is closed, it causes a short-circuit and the following phenomena occur: The bottom of the camera becomes extremely hot near the battery cover; Batteries that are loaded are depleted quickly; The number of shots that can be taken becomes extremely small.

If you open your battery slot and notice the opening/closing spring sticks out like in the ones shown in the images above -- they are affected by this malfunction, do not touch them, as they may be extremely hot.
