If you need to replace the LCD screen of your Lenovo ThinkPad T480, follow this guide. The LCD screen or liquid crystal display is a type of flat-panel display. It uses liquid crystal film between glass plates that when voltage is applied its optical properties change and images are displayed or hidden.
If damage or failure occurs you may notice missing pixels, the color could be off, or the screen could crack if it is dropped or sustains a fall.
Prior to starting this repair, be sure to disable the internal battery, turn off the device, and unplug it from the charging cable.

If the internal battery is disabled why do you need to remove it?
Hi Dan, if you disconnect the internal battery from the motherboard, (Step 12), you should be fine. We just want to make sure that there is no power to the system and the step to remove the battery is included as a precaution. Thanks!
@sarahw thank you but my question was more about why do you need to physically disconnect the battery if it is already disabled in BIOS?
