I thought I'd expand the survey. For those who have had it happen, do you have any theories on why (excess sleep, plugging/unplugging the power supply while on, etc.) it happened? Has anyone had it happen after DT&T replaced the IO Board? Obviously those new to the 2400 wouldn't really know. GLOD - Green Light of Death, a not always terminal disease that can require the replacement of the IO Power board, not necessarily the entire motherboard. The 2400 site has some resuscitation techniques. ~ Larry, Darn Good Design PS, Mine is still chugging along nicely and giving me two or so hours from the battery while playing games at Starbucks this morning.
