Intel seeks light sensors to halt laptop scalding

Having an overheating laptop nestled on your legs isn't exactly the most comfortable way to work, but even if your Li-ion doesn't erupt on your mid-section, other forms of damage can still ruin your day life. In an effort to quell the scalding that so often occurs on today's lap-burners, Intel has issued a patent application "which uses light to sense when a computer casing is getting too hot, and automatically throttles back the power" to cool things off. Considering that hot spots emerge in various locales on the casing, a light sensor would be used to detect changes on an internal thermochromic coating, which would then relay a signal to the processor to clock down a bit in order to keep the temperatures within reason. Of course, we fully expect a taskbar icon to disable this CPU-limiting procedure for those rocking flame retardant pants, but this should work just fine for those who prefer not to dress accordingly while computing on the go.
