Ciao,
My Neo1973 wan't start anymore.
Sometimes it happened (I think to all of us! ;) ) that NEO1973's battery
goes fully discharged, and for this I follow the instruction on the wiki
pages (detach battery 20 seconds, attach to USB, wait 1 hour, start the
Phone).
It does function allways till this time.
I've waited 40 hours and now the battery gives 3.72 Volts, but the Phone
doesn't start the same
I know the problem well. It sometimes can occure,
while neo is connected to usb-host, and somehow is not
recognized by the usb-host. This happened to me on
after a reboot of neo while connected a couple of times.
I made myself a little "emergency" charger made of an
old mobile-or-something power adapter (6V, 150mA) and a
resitor (10 Ohms) between battery and poweradapter, which
did result in a charging currency of around 150mA (picture
attached).
See the symbols on the battery for polarity. TM stands
for temperature monitor.
After a couple of hours the battery will have enough charge
to be further charged in the neo on usb-port.

Thank you for your suggestion, Marc, and also for the photo (why don't you put
it with a brief description on the battery page of wiki?).
I may do that sometime :-)
My problem seems to be quite different.
Now my battery is full-charged (3.90 volts on my digital multimeter) but the
phone won't start the same!
I agree, from my experience 3.90 Volts should be enough to boot.
Even 3.7 Volts should do.
A fully charged battery will have around 4.20 Volts though. I've only
reached this while charging in the neo though.
Sorry for not being able to help :-(
Marc
