Notes

To select a boot device or enter BIOS setup: press ENTER immediately when the red Lenovo logo appears. You only have about a second.

It is likely possible to control the battery charging to extend the lifetime of the built-in battery; see Thinkpad battery management. I have not tested this on the T480.
