Feb 4, 2013 10:05 AM in response to cruserjby SP Forsythe,It is normal for it to take a few seconds. The SMC (System Management Controller) will take a few seconds to ascertain the charge levels, and then direct current from the adapter appropriately. I think I have noticed as long as 6-8 seconds. Is yours significantly longer?

Feb 4, 2013 10:11 AM in response to SP Forsytheby cruserj,Well, to be honest, I haven't timed it.
Just now was the second time I'd noticed it; and, panicking, I kept checking the power supply.
I'd guess it was minutes rather than seconds.
