I Disassembled my Acer Predator Helios 300 g3-571 to change thermal paste and m2 hard drive.

I unintentionally broke a brown connector near the battery. I re-assembled the computer and it all works fine.

The connector seems to have a label on the motherboard "JBL1". Does anyone know what is it for?

[Edited the thread to add model name to the title]

    Thats the keyboard backlight, check your keyboard lights works, as D below is that connector and cable. You need to get the FPC mobo plug replaced and unfortunately you need a microscope and micro soldering tools as this FPC plug is small and needs the proper tools to replace or as a temporary fix, plug the flat cable into the plug and put tape over the top so that your keyboard backlight works until you can get it fixed..
