Comment:

 Thanks.  I've not seen this yet on Darfon power supplies on 240V 50Hz.  It
 is difficult to tell if the power supply tripped, or if the laptop failed
 to indicate correctly.  Please report the OpenFirmware and EC version.
 You can find these just before the ok prompt.  Please make the symptom
 happen again, and then:

  * do not remove either power cord yet,
  * turn on the laptop, hit escape to get to the ok prompt, and type watch-
 mppt
  * note the Vin value, and whether it is stable,
  * remove the plug from the laptop, wait five seconds, then put it back
 in,
  * note the Vin value, and whether it is stable, and whether the power LED
 changes,
  * if the power LED is still off, unplug the power supply from 240V 50Hz,
 wait five seconds, then put it back in,
  * again note the Vin value, and whether it is stable, and whether the
 power LED changes.

 (If you have an open wireless access point, you might more easily capture
 this data using the telnetd in OpenFirmware).
