m18 R2, repair issue, stadium lighting

Hi All - I had a service call to replace my keyboard due to a cracked cap (M18R2). Keyboard works great, but I noticed the stadium lighting no longer works. Does anybody know how it's connected to the motherboard so I can try to fix this myself? Also, part of case isn't in correctly (at the monitor hinge) if anybody knows if I can fix that too that would be great. Thanks for reading and thanks for any help!
