Comment (by ted.juan):

 No matter is Q2A42 or Q2A51 BIOS all will happen the serious prolem.


 The root cause is the EC won't do the precharge now.


 EC can't recognize the correct Battery type since there is no enough
 voltage.


 Then it won't do the charge because there is risk to charge the unknown
 battery.

 The new EC version PQ2A62 will fixed the problem.


 It will precharge a short time,then try to read battery type.


 If it still can't recognize the battery, just stop to chrage.
