Hi,
I recently purchased an Aspire K3 I've had it for roughly a month, now when I go to charge it the battery indicator under the button flashes a blue ish colour non stop.
I've had a look around to see what this means in the hand book but I don't see any mention of what it could mean.
This flashing could mean a short....make sure you clean the 510 connections real good and check your charger connections on the bottom of the battery for debris, and/or try another charger altogether.
