System started auto waking up after 5-10 minutes

This problem just started last night, and I have a feeling it might be related to the optional updates I installed. (Win10 update is both hidden in WU and disabled in the registry for now, I'm giving it a couple of months to shake out first.) At first I thought it was my external keyboard/mouse acting up, but I removed the dongle and it still happens. The event viewer shows lots of these events:

The system has returned from a low power state.

Sleep Time: ‎2015‎-‎08‎-‎05T22:33:29.891174000Z
Wake Time: ‎2015‎-‎08‎-‎05T22:42:54.338772700Z

Wake Source: Device -ACPI Lid

Every time it sleeps now, 5-10 minutes later it reports that the lid opened, when it certainly did not.

The updates I installed yesterday were:
3075853
2976978 (I'm thinking of uninstalling this to test it, I wonder if the new metrics is waking it up)
3071663
3055343
3035583
3065013
3072019

Oddly enough, I had already installed 2976978 on July 28, and it must have been reoffered or something, because WU prompted me to update it again. In the meantime, has anyone else seen this and narrowed down the cause?

Edit: I've ruled out some of the Windows Updates. It actually stays asleep if it's unplugged, so I'm going to assume it's a hardware problem.
