If the small screw/battery tabs (which hold the battery in place) are broken, is this always indicative the laptop has been dropped?
I would have to say that I would have a pretty hard time coming up with other scenarios that would be responsible for those plastic battery tabs getting broken…other than the computer being dropped…or bumped pretty severely against an object.
And I am surprised that no external damage is present (but the battery tabs are broken). I guess the computer could have landed just right (in a fall/drop)…where the exterior wasn't damaged…but the shock was still enough for the brittle plastic tabs to break.
It is possible…that someone was working on the inside of the computer…and maybe over-tightened the screws (breaking the plastic tab's). It is a VERY good idea to disconnect or remove the battery when working on the inside. So this could happen.
Also (who knows)…that battery could have been replaced with a used battery with broken tabs.
But of these three scenarios…the dropped or seriously bumped computer would be my statistical 1st choice for the broken tabs (let's say a "guesstimate" of 90-95%)…maybe more. The other two scenarios I mentioned would have a far less probability.
Although many folks can be pretty bad about over-tightening screws (if they were working on the inside of a computer).
