I have one that is 6 years ancient and running 24 hours a day 365 hours a year. The only time it is off is when there is a power outage. Yes it’s been repaired a few times also .

The choice is yours to make, I made mine to keep because I repair my own computers and everyone else’s.

Sometimes you can buy from ebay at a very low cost. It’s simple to check out the seller for reputation etc…
Unless you have lots of cash, try and fix it. Replacing with second hand parts can sometimes be the best way to go to save money.

After you graduated and landed a excellent paying job get a
better laptop.
