No idea. According to the mfg it's "automatic", whatever that means, and there is no user interaction possible.



Just found this:

http://www.geardigest.com/2005/08/30/the_turion_64_inside_story/page5.html
It seems its automatic and can be adjusted via "power options properties".


Ah, this might explain what's going on. It seems that the clock cannot or at least does not drop below 800MHz. That's still a whole lot of MHz when doing mundane things such as layout checks. This is what I use my laptop for most. There, I can't see much difference between the old Compaq throttled to 25MHz or so and the new screaming fast laptops. Except that the old Compaq's enclosure crumbled and I can no longer enjoy 6hr runtimes because "modern" design don't deliver that :-(

Why don't they allow a drop to, say, 100MHz or less? Many laptops are routinely used as document displays during meetings. That requires close to zilch in horsepower.


I get about 4-1/2 hours on my 2-1/2 year old Thinkpad T42P, and you can get second batteries that go into the DVD drive slot that will give another 2 hours or so, so that would get you back up there. You have to get the 9-cell battery and not the 6-cell one--the good ones stick out the back of the machine by an inch or so.


Maybe this mfg (Twinhead) has those, too. But it's weird. Instead of making machines more efficient or at least as efficient as those from the early 90's it's like this: We've bloated our OSes and programs, therefore you need 1GB of RAM and 1GHz of clock to write "Hello World", and the solution is to just buy bigger batteries.

I still don't see any reason why the processor should run anywhere above, say, 10MHz while I am staring at Gerber files. It just doesn't make any sense to me.

Might be like the DRAM vs Static RAM Problem. To get the smallest Trans Cells they have to be quasi-dynamic.

I've just heard of various attempts over the years of making truly Static Microprocessors. They were never the larger ones.


That might be the case. My 2nd laptop had a 486 and that must have been static. AFAIR the lowest clock speed it could do was 1MHz. Absolutely great if you had to write a lengthy module spec in MS-Word. I sat there typing away on a transatlantic flight and the old NiCd in there was still cranking after 5 hours. The guy next to me with his fancy Thinkpad was in utter disbelief because his had quit two hours before that.

Perhaps you might keep an eye open for something like these:
http://www.pocketpcfaq.com/wce/21/dreamwriterit.htm


I was looking for something like that a while ago but after the old ones from the 80's disappeared (Casio? Sharp?) nothing replaced them. IMHO a market opportunity but nobody fills it. The general problem with such devices is this:

"However, the DreamWriter is an "education only" device. So, you won't be seeing any at the local computer store." (Quote from your link)


Or the old Tandy T100 & T200 series. Battery lasts quite a while if you just want to write on a long trip.
