  • I have loaded 12.93 beta into Edge 520. If only unusual power issue being fixed in 12.93 and nothing else changed, the battery issue would still be existing. I actually have filled out a form for 12.93 beta and sent it to you yesterday. All activities and error logs are attached. Please find mine in your mailbox.
