In September of 2012, I bought a T430 from Lenovo. I loved that thing! Covered it with stickers, even upgraded it as the years went on.
Eventually, it had a Core i7-3820QM with 16GB RAM, 1080p screen (with an adapter), SSDs (plural, I put one in the UltraBay)... I installed Coreboot with Tianocore, upgraded the WiFi card... I even modded in the keyboard from a T420.
In June of 2022, 10 years later, I bought an X270 off eBay. I could still use the T430, it was just starting to feel sluggish... I just felt like I needed a new laptop. I'm very happy with the X270 and I hope to use it as long as possible.
It was also fun to start covering it with stickers all over again!
I still have the T430, it's just not being used and it's sitting in a storage locker (with my vintage computer collection).

A cleaning and re-paste will bring it back. If on windows maybe time for a windows re-install.
Typed on a T430 via BSD that was just re-pasted and cleaned, not sluggish anymore :) If you are interested *BSD, I can confirm both NetBSD and OpenBSD works great on the T430 I have.
