The other question is this:
If she needs more hard drive space, and/or a new battery, the expenditure would be about $150 for battery and 256GB drive. Add $70 for a 512GB drive, so about $220.
The computer sells for about $300 on eBay.
So, a brand new one, with better spec, etc is $900 ($600 after selling the old one). Is it worth upgrading it for $220? I think not.
