I just caught the 5-LED battery charge state indicator on the far right, flashing all 5 LEDs together. Everything was powered normally. Single "AC power filtering" LED on as normal. No or one load LED on as normal. No 'transformer grunt' to say that it was trying to produce power from the batteries. In fact nothing abnormal except those LEDs flashing. I've never seen it do this before. Just as suddenly as they started to flash, they went back steady, as normal. Then, as I was typing this, they just flashed again about four or five times, and have now gone back steady again.
Anyone know what it's trying to tell me ?
TIA
