Hello danito Thank you so much for your help!

Unfortunately, after flashing that provided file, I'm still experiencing the same issue.

- With battery pluggin in, power led turns on for about 3 seconds, then caps lock flashes and then nothing
- Without battery plugged in (and power usb plugged in), high pitch sound from the same area as the usb plug
- (edit: I can hear a less intense whine from the same area when the battery is plugged in regardless of the usb power being plugged in)

From my research this would indicate that there's something...
