I have a Toshiba AMD processor which came with WIndows 7. However most of the time I dual boot into Ubuntu 12.04 LTS because of comfort and security it provides. However when I use Windows mode, I feel and/or apprehend that it seems to be warming up little too fast. Is this the nature of AMD processors or Windows making it do that? One of my friend says that carrying an AMD processor-laptop to warmer place like Chennai, India may compound the trouble? Other than this heating issue, I do not find anything bad with that. Any solutions or pointers or enlightenment?

--Brisingr AerowingYou are joking, right? The CPU is made of CMOS transistors, called MOSFETs. The special thing about those transistors (and the complementary way they are wired up) is that they draw pwer only when they are switching between states, but not when they hold their state. And, like all processors, all energy they use is converted to heat to almost 100%. That is why a processor is cooler when it's idle and much hotter when it runs at maximum. Two different programs (operating systems are also programs) may have the CPU do more or less work, so they may heat up the CPU faster or slower, depending on te average activity.

Have you checked the Power Management settings? Windows will default to *full power* desktop mode even on laptops. My old AMD Turion used to overheat & blue screen regularly with XP power settings set to minimal power management. X|
Reducing the clock frequency may lower the heat and power consumption, as well as the processor's performance of course. When running on its battery, this may be a good compromise for a notebook and buy you some more time. In no case it should be needed to prevent overheating.

Probably not. It's not a given that someone who does programming knows anything about how the machine they program works, and it's extremely rare to find that level of knowledge. There's no reason most programmers would know that, so be nice. :-D Good explanation, by the way. I'd go into far too much detail about transition times and duty cycles and stuff nobody really cares about. Except you and me, of course... ;P BTW - MOSFETs weren't always made with CMOS technology, and the early ones could be quite leaky. ;)

I would do it tonight and revert back.

I just fear the day when there are only the 'don't have to know what I'm doing' guys are left over. I already see them dancing around the computer with masks and rattles. :)

I Still know how to read a data sheet and have even done so recently :)

Sure n-MOS and p-MOS. Using them together is the complementary part. :)

Overheating was a problem with the HP Pavilion I had. The fan was underneath and so using it on your lap blocked the vent. (more of a design flaw really) but the heat generated by laptops i've owned over the years, have in my experience, been uncomfortably toasty. My last netbook was an improvement over the pavilion, but still not usable for any prolonged sessions when used as expected, on my lap. Being mobile you have to expect some compromises, and I'm afraid that CPU speed and graphics performance need to be reduced.

--Brisingr AerowingWindows doesnt do individual core CPU throtelling, inlike LInux, so you will get higher power consumption on Windows. Of course I wrote a driver for windows to control the CPU speed under app controll, you can run any app flat out and set the CPU speed as you like. Doing so totally pissed off the Windows kernel dev community but what the hey, they should write a better OS, like Linx! :)
============================== Nothing to say.

Yike! You broke the code! Now we'll have to kill you...:suss: Back when RCA was first playing with CMOS, a college buddy of mine worked for a company that got free parts to evaluate in exchange for writing app notes for RCA. They built an entire low-power radio receiver system on a single card, and in testing it worked almost perfectly, but not quite. On investigation, they found that the circuit board designer forgot to include power runs for the chips. The input protection diodes rectified enough of the incoming radio signal to power the whole system! CMOS was one of the greatest inventions of all time, I think, followed by the VFET.

Next you are going to tell me that you have some CDP1801 left over :)

Sorry, no. I used the last one as a fishing lure a few years back. :) But I do have a couple of 100 MHz FAST Fairchild shift registers, and about 10 VN66 VMOS power transistors in my tool bag. I might even have a couple Signetics SN25120 Write Only Memory (WOM)[^] chips in there somewhere.
