alt Hacker News>The older they are, the better they are
Everyone agrees the build quality used to be better (my grandpa already said this about appliances from his youth). But one thing I almost never see discussed is the power consumption of these old devices. Older CPUs often double as room heaters. Modern ones, especially the Apple M-series, have become a lot more efficient. So while I agree that modern laptops suck in many ways, I would do the math to see if it's actually cheaper to buy and use an older computer. Maybe not if you're in Qatar or Russia but some countries have extremely high electricity costs.

ThinkPads use 20V chargers. USB-C supports 20V power delivery. What's the efficiency of power adapters back then compared to current gen USB-C chargers?
It just isn't really a measurable impact against an overall picture.
At maximum, a T580 can draw 44 watts. 8 hours per day, 365 days a year, at 50 cents a kWh (quite expensive for the US), that's $65 a year. That's a several-year-old computer already.
The W520 can draw a much higher (but still low relative to a desktop) 150 watts. The cost per year to run it would then be around $220/year - but again, that's assuming maximum power draw for much of the day every day. Your home refrigerator uses more than twice that.
For most people, I don't see this cost increase as a problem.
