hello.. tell me one thing only. is it possible that any problem inside the desktop can stop the ups giving output untill a restart of ups?? is it possible??? actually some days back my ups was failing to give output sometimes even when the ac power is present. but at the time of power cut it gives 20min of backup easily. but nowdays sudden shut down of pc is happening. and when im checking the output of ups there is no output at all. but after a restart of ups all are fine. this was happening frequently 2days back. but last 2days i didnt face any problem like this. any reply is welcome...
