Hi,
Found this site in my search for how to repair an ASUS laptop with the backlight issue on Battery. I've been a tech since 74 after I left school. I know (a bit of) stuff and I fix things, is basically me. I'm currently retired. I've currently have over 40 IoT devices on my home network. Anyway, that's me. Hope I can help anyone else in the areas that I know.
BTW, My handle comes from the fact I played drums in bands for many years.
regards.
