Well she never dropped the charger - so you can be pretty sure that any alternative charger will behave the same.
But she did drop the laptop so you can be pretty sure that the laptop is quite broken inside - they are not intended to be dropped.
The power light going out on the AC/DC adaptor suggests that the laptop is "eating" all the available DC power.
The choices you have are - self repair - depot or shop repair - new machine. Unless you have a service contract - in which case do not mention the dropping.
