The old turn off and turn on again, but you have to wait for the battery to go flat before it fully turns off
Looks like mine has come good as well, mine wouldn't respond to any buttons.
But I've also noticed, there's a "reboot device" button on the util.
I also hit that, after it rebooted it seems to work, I'll finish charging battery and see how it goes.
