Anyone here experience a total, random shutdown? Just noticed that one of my PXLs has been totally off since last Sun (5 days). Power was there (FIOS router + Apple Airport also on same APC, so would have noticed asap) plus PXL power cord was still firmly in place. PXL would not respond to remote commands, front LEDs were not registering anything so pulled the cord to reboot. Everything seems fine now but have never experienced this.
