So ive had my t480 for 2 months now. About 1 month ago the trackpad and trackpoint started observing unusual behavior. When i boot the machine up, the trackpoint doesnt work, but the trackpad works except its very laggy. Eventualy when i start using the machine, the trackpad starts to work regularly. Ive checked the bios settings, xorg config files (i use unix based operating systems usually) and ive tried using windows. None of these worked. So it seems like a hardware issue. What do i do?

Hello and welcome,
This is totally out of left field... but I've seen similar behavior when testing live Ubuntu on an X280.
It's fixed (perhaps w/out advanced touchpad features) by adding "psmouse.proto=bare" (w/out the quotes) to the kernel line in the grub boot stanza.
Can't explain why it would suddenly change on your machine, so as I said... out of left field...
