 Re: dv6258SE base hot when usingMessage #2 Posted by Eric Smith on 1 Mar 2007, 8:01 p.m.,in response to message #1 by Scooby Doo This isn't really the right forum, and I don't have that model (I've got a dv5210us), but basically all laptops/notebooks do that. A laptop typically uses 30-40W, and converts more than 95% of it to heat. By comparison, a heating pad uses about 8W and reaches 170-180 degress Farenheit. So naturally the laptop will get very hot, and won't be too comfortable on one's lap. If the laptop has a fan, make sure the vents are not obstructed, as the forced air cooling will exhaust some of that heat into the room rather than your lap.

 Kahan's Integral for LaptopsMessage #3 Posted by allen on 1 Mar 2007, 10:45 p.m.,in response to message #1 by Scooby Doo The probability that a laptop will get hot if insulated while running can be expressed as the integral: ``` /x=1 | P = | sqrt(1^(s!!!)) dx /x=0 ``` Where s= the Processor speed in hertz. (undefined at s=0) Richard P. Feynman spoke about this very issue in one of his later books. In brief, entropy is the way of the future.
