Yesterday I had the following problem with Rockbox 2.1:

My batteries were totally empty.

So I connected the power supply to the Jukebox
Recorder to charge them.

Then I wanted to listen to some music.

I pressed "On" a few times and finally got the Recorder to
boot Rockbox 2.1 from harddisk. (Rockbox Logo appeared)

But everytime I pressed a key in Rockbox, a message
saying "battery loading" or something appeared and the
Rockbox firmware didn't react normally to the keys.

In the background I saw the file list.

Disconnecting the charger caused the device to power
down immediately (of course...) since the batteries were
completely empty.

I wasn't able to get a playing and charging Jukebox.

I thought playing and charging would be possible?

I tried to press the "Play" key for a longer time. This
caused the hard drive to produce a series of awful
clicking sounds. When I stopped pressing the backlight of
the display was somehow blinking...

I think this is at least bad error handling.

It would be fine if you could fix that... ;)
This task depends upon

When the batteries are completely empty, they don't have
enough power to spin the disk. This is why you had a hard
time even booting into Rockbox.

Wait an hour or so and everything will work again.

This is not a Rockbox bug, it's a hardware design issue.

When the power supply was connected to the box, I was able
to boot Rockbox. Isn't it possible to stop the battery loading
process and use the power of the ac adaptor to spin up the
disk and play mp3s?

Unfortunately not. The archos charger charges the batteries,
which power the harddrive. Thus there has to be a little bit of
power in the batteries to use the archos even when plugged

We can only turn the charger on and off, not route power to
specific components.
