This morning I woke up and found I couldn't turn on my neo... even
though it was plugged in [usb] all night! It was plugged in directly,
as in no hub, and yes, the PC was on overnight.
I'm not sure what happened... I was playing with gsm and bluetooth
[ssh'd in over bluetooth] when I powered it off. I probably just put
it to sleep, actually, not hard off. So possibly the bluetooth was
still on drawing power, and maybe the gsm was still alive, and the cpu
was keeping its memory warm too. So possibly this was taking more
than 100ma? I didn't even think I had anything to worry about since
it was attached to USB 5V that should be able to put out 500ma. I
figured it'd be fine to leave it in that low-ish power state
overnight.
I'm attempting to charge the battery now, the Neo 1973 emergency
charging way listed on
http://wiki.openmoko.org/wiki/Neo1973_Battery_Charger So I have my
fingers crossed that it'll come back to life.
The page you cite implies that you can use a reasonably arbitrary USB
charger, e.g., from a Blackberry, to charge your Neo:
"An alternative method is used if the proper charger for the Neo is
used. If the Neo measures 48kohm +/- 1% between usb pin 5 and ground, it
will detect the dumb charger and use it for fast charging."
Has anybody tried this, specifically a Blackberry charger?
3. Should a voltage always appear on the +/- terminals of the battery,
or does that third pin need tickled in some way to get a voltage
out?
I had my battery out the other day when in similar circumstance, and
measured around 3V across the +/- terminals with no tweaking, so I
suspect that it should always appear.
