I need your help. I'm currently in the 2nd year of a CS degree and I don't know if I should buy a new computer now or wait 'till I finish my course.

I have a HP Pavilion G6 with about 6 years old and still using HDD and critical state battery.
My question is: should I upgrade to SSD, buy a new battery and keep this laptop until I finish my course and then buy a new one or buy a new laptop now? I'm thinking about maybe some ThinkPad or XPS or Zenbook.

Are we just programmed to stay awake all night? Even if we have nothing to do?

Like, it's 4 a.m. in my country and I just can't fucking sleep! What is this?!

I just switched to iOS and it's being an amazing experience.
So great to finally have access to all my files, and personalize my device as much as I want.
And it has no virus so it's all good news.
