SP4 Battery drainage while shut off on 14342

[Robindjuret]

This is one strange 'bug'; Since I installed 14342 on my SP4, the battery drains to zero overnight when I shut the computer off (not sleep or hibernate). I haven't had time to roll back and that might cost me. I wonder how much this is gonna effect my long term battery life. When I signed up for this thing I was willing to accept buggy software, not destruction of my $1200 hardware. Anyone else got this problem?

More than likely it's not fully shutting off. Tap a key on the type cover and it'll probably light up.

For now, hold the power button down for 30 seconds to fully shut it off.
