alt Hacker News>I could still use the T430, it was just starting to feel sluggish
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.
I think it's currently running either Arch or Manjaro (I forget which) and maybe a quick re-install and cleaning of the fans/thermal paste could help. I dunno, I just got the feeling that I wanted (needed?) a new laptop...
