power outages

I have a HDR-2000T Occassionally the power is cutting off, annoyingly of course when it's recording. I unplug, wait a few minutes then put the plug back in and it then works fine. This has happened a few times over the last cople of weeks. Any idea of what is causing this annoying problem...

In the event of a power outage, the HDR-FOX can end up in the half-awake state when the power returns. This happens if the unit was fully awake when the power cut occurred. If the mains supply is interrupted while the unit is in full standby, when the power comes back on, it boots up briefly...
