M6807 refuses to work at 800MHz on battery

[lionsh]

I have my emachines for 5 months, love it very much.
Sometime ago I noticed that the battery runs uot to fast. I saw that even when I'm working on battery the CPU speed indicates 1.8GHz in My Computer \ Properties... and in AMDinfo tool.

I onced wanted it to be like that. But I don't wan't it anymore. I want it to run at 800Mhz on battery.
I don't know what I changed to make it work like that. I sure didn't intend it , I never changed the bios and all that stuff.

It doesn't matter if I change the power scheme from "Always On" to "Max Power".

How can I get it back to the previous settings?
please help me...

Set it to portable/laptop in power schemes.
If fails, try uninstall AMD64 driver and reinstall, reboot.
Check task manager, you might have some heavy spyware/virus in the background eating your cpu cycles, which will cause your cpu to seemingly be stuck at max speed.
