The college she goes to is very likely to make her buy/lease a computer from them, at their price, which could be $700/semester.
So if you could get a tune up on the old one, clear out the stuff that’s making it run slow, and eke it out for two years, it might be a good idea.
My daughter is a senior and pushing for a new computer.
We’ve already decided, she and I, that she will take online courses to complete her first 2 years unless she gets a full or mostly full ride on scholarship. If she gets a full ride and has to lease, then her brother will be happy with the lappy.
-rhyme-master LOL.
