I'm back now, and I have a couple. Should I mail you one?

problem is getting a good battery. Local stores don't carry battery

A sure fix should be: insert "good" battery, attach wall-charger, boot all
the way to system, replace "good" by drained battery *without* switching off
or suspending system.

Yes, I can run off usb without the a battery. But if I have a drained
battery, I cannot. Seems like charging pulls too much power so I
cannot run.What I had to do at one time was pull battery and charger
out. Hold down the aux key. Put battery in. Put usb in. hold down the
power key.
release aux key. wait for menu. When I did this the battery starts to
charge.

Na, mine wont run off USB power. I'll double check on a 2nd computer.
My unit is pre production, but I know guys have done battery drain
tests With no problems. So, scratches head....
I tried with the battery in, battery out. Sean, can you run yours
while plugged into usb with the battery removed?
You have a phone from the same batch I have.

Some do, some don't. E.g., I never got any GTA02 (out of 1-2
samples) to run from USB power for more than a few seconds.
Regarding charging, the big issue seems to be that we turn off the
charger if we don't have USB power. The PMU remembers that setting
while it has any power at all. Thus, if the battery is empty and the
charger happens to be turned off, USB power is simply ignored.
So far the theory. I've tried to actually confirm that behaviour (so
that I could observe an improvement after changing the logic), but
only got more or less random results, with the system occasionally
not charging when it should, and (quite often) happily powering up
when I didn't expect it to :-(
So there seems to be more going on than meets the eye.
