Solved! I need to find the model #

Hp laptop/notebook 15"screen

Model number should be on a sticker on the underside of the laptop, potentially in the battery compartment if the battery is removable.

Type cmd in the windows search bar and a black box will show up. That is called the command line.
Type "WMIC CSPRODUCT GET NAME" without quotes and below you'll see the model!
You can do the same for the serial number "WMIC BIOS GET SERIALNUMBER"
