i have already did repairing just now with windows 7 but the result is justt the same, my phone is back to died after for a couple second , the point is i can get inside to normal display for standby ready phone but the power can not for long time life but only a bit second .
is it expensive batterry for my SP, and this is because internal batterry so can not so easy that we can replace with our own hands
we have to open go to inside for all open and then we can make new batterry but the process is verry dificult because it is not normal for comfort process
i love sony but like this problem make confuse also for me
and for your diagnosa is this about my batterry problem because my indicator while this phone is on that i can see my batterry is 80 90 percent but always died by it self.

You should have the device examined at a sony service:
