I have a new Mini 10 purchased thru Sam's Club. Really happy with it, came with the 3-cell battery. Purchased a new 6-cell directly from Dell. When I replaced the battery I find that the 6-cell is not securely attached to the netbook and it falls off when I pick up my Mini. I've checked the release latches, the left side (when looking at it on the bottom) sort of "snaps" when secured, however the right side feels a bit mushy when the battery is in place. This is not the case when the 3-cell battery is attached, both latches are firm. The 3-cell is snug on the backside of the Mini. Any suggestions? Or might I have defective battery latches on my new Mini?
