I have a Fujitsu-Siemens Laptop Amilo La1703 with a Turion 64 MK-38 cpu (2.2GHz) on a via chipset.
The Bios does not have any CnQ options etc. It has very limited options there.
But that doesn't seem to be the problem.
It came with Vista Home.
When I plug it in, CnQ runs as expected. 800MHz when idle, goes to 2200MHz when I run sth.
But when I unplug it and run on battery, it is stuck at 800MHz, and nothing can make it go any faster.
I upgraded the BIOS from 7.0 to 8.2 but nothing.
I installed winXP SP2 Pro to test it, but it is the same.
I used AMD XP driver 220.127.116.11 and 1.3.2.0053 , nothing.
I have changed all power schemes in both OS but it is always the same.
I use SuperPi as a cpu intensive task and cpu-z to monitor the cpu speed.
I plug & unplug the power cord during SuperPi calculation and it goes like this all the time.
800MHz on battery, jumps to 2200 when I plug it, drops to 800 when I unplug it.
(and if SuperPi is finished while plugged in, it goes back to 800MHz, so CnQ works when pluged in)
The notebook is 5 months old, it was rarely used during this time, and I didn't notice this earlier, maybe because I didn't have to do a cpu intensive task on battery, or maybe the problem wasn't there before, I can't say for sure.
