Operation without battery (GTA02)

I have two 100% reproducible issues with my GTA02.

1. When running with the battery in (charged enough) and a USB cable  
plugged into a computer, removing the battery makes the phone die. It  
seems to turn off several seconds after the battery is removed. If the  
battery is replaced quickly enough, the phone doesn't turn off. While the  
battery is disconnected, some things still run and some seem to stop; e.g.  
the GPS chip stops sending NMEA sentences but continues doing so when the  
battery is put back.

2. When the phone is off with no battery in it, plugging the USB cable  
connected to a computer makes the phone emit a buzzing noise. The noise  
continues until the cable is disconnected. The phone won't start up in  
this state, not even in the NOR menu. I remember a similar issue in GTA01,  
but GTA02 was supposed to work without a battery.

Can anybody reproduce?
