I run things until they don't, and then keep them running anyway.

I also have a second broken laptop, an XPS 15 from 2016.
Its internals are working, but it's missing a battery, a display,
and it's got a broken keyboard and a fan that's broken.
I'm not sure I have the skills to replace the keyboard, but I can try.
It's a high-spec 4-core machine with 16Gb of RAM, and still very
usable these days, but it'll take around 400 dollars to repair,
as a new original screen is expensive (290), battery isn't cheap (60),
and parts are in general in demand as it's out of support by now.
