Replaced KeyOne screen. Charge / notification light not working

Just replaced a cracked screen on my KeyOne. Everything works as it should except LED charge /notification light. Did I mess up somewhere?

It does not light up when plugged in nor for notifications. Checked settings. Tried several tests of email sending & also used Test Mode which confirmed failure of the charge light.

Anyone know how replacing screen could have affected this? Possibly something to do with removal of back cover?

Any clues appreciated. Clearly not a software / settings issue. Thanks.

Welp LED charge light suddenly just started working while I was in Test Mode running unrelated tests. So, cause unknown.

Little bits of code that no one knows that they're doing.
