I observed that in battery mode, the frequency will drop to around 700M. However, since yesterday, the frequency drops to 1.58G even though the chip's in AC mode. What's the matter?

PowerNow does this even when on AC mode. The 3000+ has 3 steppings - 800MHz, 1600MHz and full speed at 1800MHz. This works in battery as well as AC mode. The frequency increases as and when needed depending on the cpu load. It does not matter whether the laptop runs on battery or AC.

Also Windows System properties window is know to show incorrect processor speeds on mobile cpu's. So if you want to check the cpu speed in real time I suggest getting a third party monitoring tool or you can download AMD Dashboard from the downloads section for your cpu. This will show the real time clock speeds and you can see whether the cpu is stepping up or is stuck at a lower speed.
