 Maybe it would be best if at least the Windows admin password recovery stuff was moved to its own page (not to be confused with the BIOS admin password recovery stuff)?

		+	No suck luck. But the two things that came to mind are probably incorrect, there is one much simpler reason to not want the laptop turned on while charging: ''temperature''. The battery degrades a bit faster with high temperatures (even while in storage). If temperature gets extremely high, the cells vent, and permanent capacity loss happens.
		+
		+	One should note that it is possible for the battery and charging circuit to be cooler with the laptop operating at full cooling fan speed than when the machine is turned off...
		+
		+	Now, excuse me while I go away to store my spare pack on the refrigerator :)
