Battery discharging while plugged in

USB cable connected to computer, not the charger.

yes, using 2007.2's "dim only, don't lock" option, so most of the time 
the screen is turned off, but the phone is not suspended. I don't use 
suspend.

erm, i don't know how to tell for sure, but I'm pretty sure it's getting 
500mA from the PC - it will charge to 100% in a few hours (not the 12 
hours needed at 100mA). it's plugged directly into a USB port, not a USB 
hub or anything like that. Host is running fedora, not sure how to 
determine how much power the it's drawing, but 'lsusb -v' gives me 
(among much other info):

    bmAttributes         0xc0
      Self Powered
    MaxPower              500mA

the way I'm plugging it in hasn't changed since It used to charge to 
100% and stay there.

Thanks,
