I still remember the good old IBM Thinkpads, most of them were indestructible tanks. But with Lenovo, those times are long over. My last machine was a TP L390 Yoga. It overheated frequently, the cooling system was inadequate for the 4.6GHz Intel CPU, one day the logo sticker came off because the glue turned into sticky liquid, the passive Micro-Ethernet dongle cost 50€ and the cable turned into glue after a few months...god, what a shit machine this was.
I was able to work with it for a while by limiting and undervolting the CPU, but one day a Windows update came out that disabled the functionality and it worked like crap on Linux for a long time due to bad drivers.
I switched to GPD now. Never going back, although I miss the Trackpoint a little bit.
I hope you have healthcare, because that sounds terrifying.
