My oldest running laptops that have never had a single issue are a MacBook Pro (2011 model, the high-end 15”) and a Lenovo gaming laptop that’s like 14 years old and inexplicably has a second video card you can take out of the side.

I use them both to this day. They have 16GB RAM and SSDs now, and never had a problem.

Quick edit: the MacBook Pro has its original battery and lasts over two hours at full brightness still, but has fewer than 40 battery cycles since it was originally a gaming machine for LAN parties I went to. The Lenovo has its original battery and lasts about 45 minutes still.
