"Can she keep using it for now"
If it's still letting her log in then yes, although you won't get any updates for you computer until it's sorted.
"is there anything we can do about the problem without having to go through the school ? "
Is it your daughters laptop, or is it a school laptop that your daughter is allowed to use? if it's her property then you can do what you want with it, if it's only on loan to your daughter then you need to take it back to the school.
