I have had some success (not all the time) running under Linux with
USB power and no battery, but I had to turn off the charger through
"echo 0 > /sys/.../chgmode" as well as turning off GSM.
I have also found that WiFi stops working when the battery is removed,
but it recovers when I re-insert the battery.
It occurs to me... Is it possible that even with the battery in that we
can get a brownout condition on resume?
