My 466mhz SE is shutting off, requiring a restart and to be plugged into the AC adapter in order to get it up and going again.
Some times when this happens, I even need to reset the date.
Most of the time it dies, it is showing about 40-50% battery power left.
Sometimes it dies sooner, a couple of times it does not die at all.
I have reset the Power Manager
I have taken the battery back out and reinstalled it and made sure it was not loose. It seems okay.
Am I missing something?
