Also t480 - i5-8350u CPU.
My process was to update firmware with fwupd -> change TLP to performance(depending on desktop environment you may have a battery life settings panel) -> reboot into bios and change power settings to performance.
Ran a benchmark and my CPU was running at full power when it was limiting itself to 2Ghz before.
Can’t go wrong with just booting the live environment and seeing if it works. Just check your display is the right resolution and your speakers and brightness work before installing. I also recommend checking it’s actually running off of the 1050ti too
