These notebooks seem to sell for about $300.00
This particular thinkpad ships with 8GB of ram, but can be upgraded to 16GB
It already has a SSD drive so technically you could leave well enough alone if you don’t need whole lot of space but if you do you could add more storage by either replacing the hard drive with a bigger model. 500GB hard drives go for about 200 dollars so it’s not much money for a much bigger SSD.
The battery could probably be replaced. New batteries sell for about $20.00 so don’t let the fact that this is an older computer get you down.
Total cost of the computer and upgrades would be about $500.00
